Extreme Heat Health, Safety, and Survival: Tips for Helping People, Other Animals, and Plants

I much prefer focusing on preventive health than on emergency triage. I’d rather be writing about how to prevent climate destabilization and global heating from getting worse (and I’ve been doing that for years and will continue to do that), but tragically, we have entered the age of climate consequences, and adaptation has become necessary. The climate outcomes that scientists have been warning us about for decades are here, now, everywhere, and getting worse every year. Climate instability is already causing widespread suffering, misery, displacement and migration, medical emergencies, and death. If people continue to accept and allow the burning of fossil fuels (and the degradation of our natural environment) going forward, we will get to where we are headed: we will turn our once quite habitable and hospitable Earth into an uninhabitable planet more like Mars. We are creating Hell on Earth.

Globally, this has been the hottest summer on record (which has included the hottest day, hottest week, and hottest month ever recorded)—and it’s not just because of El Niño. The last decade (which included years with a heat-tempering La Niña) has also been the hottest decade ever recorded. Unlike the “heat waves” of the past, we are now experiencing more frequent “heat domes” with unprecedented, sweltering, record-shattering daytime and night-time temperatures, across large swaths of the planet, lingering for longer periods of time. The air, land, oceans and most other water bodies are now hotter than ever, with devastating and cascading consequences for all living things.

When we’re extremely hot, it can be hard to move, hard to work, hard to think, hard to function, hard to cope, and sometimes even hard to stay alive. Heat typically kills more people than any other type of extreme weather event in the U.S.  The number of heat-related deaths is often greatly underestimated, as heat is not usually listed as the “cause of death,” even when heat is what precipitated the organ failure or heart attack or other final outcome. This study estimated that there are approximately 12,000 premature deaths from heat exposure in the U.S. each year, and it projected that that number will rise to 50,000-110,000 premature deaths per year due to increased warming. Another study found that heat killed approximately 61,000 people in Europe during the summer of 2022. Correspondingly, emergency room visits skyrocket during heat waves.

Our bodies (and the bodies of other living organisms) can only survive temperatures within a certain range. High humidity can make it even harder to withstand high temperatures (which is why weather reports typically include a “heat index” or might even talk about the “wet-bulb” temperature.) Air pollution also tends to worsen during periods of excessive heat, which makes heat waves even more deadly. Studies show that the risk of a fatal heart attack may double during heat wave days and fine particulate pollution days.

Prolonged exposure to excessive heat can cause heat cramps, heat rash, dehydration (note: severe dehydration requires immediate medical attention), heat exhaustion, and heat stroke (which also requires immediate medical attention and can be fatal). See the graphic above for tips on how to tell the difference between heat exhaustion and heat stroke, and what to do if someone is showing symptoms of these.

Those who are particularly vulnerable to the dangers of extreme heat include: homeless/unhoused people (and their pets), older people, people who work outdoors (e.g., farmworkers, landscapers, construction and road workers, etc.), people who work and/or live in non-air-conditioned spaces, people who live or work in urban areas or “heat island” zones (areas that have a lot of dark and unshaded surfaces, such as asphalt pavement and roofs, and relatively few trees or green spaces), infants and young children, people with pre-existing health conditions or disabilities, pregnant women, incarcerated people, first responders, and athletes, as well as livestock, pets, and wildlife.

Basic tips for survival, health, and greater comfort in high heat:

  • Always stay well-hydrated (i.e., drink plenty of water throughout the day). Keep a water bottle with you wherever you go (but don’t leave plastic bottles in hot cars or sitting in the sun, where the heat will soften the plastic, which will then leach into your water). Also eat foods that are hydrating (e.g. fresh fruits, such as watermelon and cucumber). Avoid drinking alcohol or caffeinated or super-sugary drinks.
  • Wear loose-fitting, lightweight, and light-colored clothing.
  • Avoid going out into the heat (or exercising, watering your garden, or driving) during the hottest parts of the day (afternoon through early evening). Cancel or reschedule activities as needed. Early morning is the coolest time of day.
  • If you’ve been sweating a lot, drink even more, eat something salty, and make sure you’re getting plenty of electrolytes (potassium, sodium, calcium) and other minerals and nutrients.
  • If you’re feeling too hot, wipe a cold, wet washcloth on your face and body and/or run cold water over your feet and hands or head; or put some water in a spray bottle and spritz yourself as needed; or when you can, take a cool shower or bath. Or you can sit in front of a fan with a cool, damp towel on you or between you and the fan. If someone is over-heating (e.g., showing signs of heat exhaustion), put cold water (or ice/ice water) on the neck, armpits, inner thighs, and other places where heat gets trapped and a lot of blood vessels are just beneath skin, to help cool down the person faster.
  • No one should be left sitting in a non-air-conditioned, stationary car when it’s hot out (especially infants, children, elderly people, and pets). Rolling the windows down does not keep cars cool enough when the sun is beating on them.
  • If you’re outdoors: Stay in the shade as much as possible, and drink extra water. Take regular breaks from any physical exertion, or avoid it if possible. If you have a hand free, use a parasol (or an umbrella) to shade yourself from the sun.
  • If you’re indoors and you don’t have air conditioning (or you’re trying to minimize your use of the A/C to conserve energy or money, or to keep the grid from collapsing): Use fans (or evaporative “swamp” coolers in really dry climates). Cover your windows by closing the shades, blinds, curtains, or shutters. If you don’t have opaque or thermal window coverings, you could temporarily put up big sheets of cardboard or rigid foam or hang thick blankets or tarps inside or outside your south- and west-facing windows (and/or your windows that get the most direct sunlight) to keep the heat/sun out. Avoid running the oven, stove, dishwasher, washing machine, and dryer on the hottest days, and especially during the hottest hours of the day. Turn off any lights that aren’t needed (especially any lamps that are still using old incandescent bulbs or halogen bulbs, as they emit a surprising amount of heat). Unplug appliances or electronics that you aren’t using. If it gets cool at night—or any time it’s cooler outdoors than in—open your windows to get a cross-breeze; you can also use one fan as an exhaust fan to help push the warmer indoor air outside. It can be too hot to share a bed with someone else; if there’s nowhere else to sleep, you might find that sleeping on a floor is the coolest place to be. If you have a basement, that is probably the coolest area in your house.
  • Make sure you have a lot of ice (and/or ice packs) in your freezer and/or coolers, especially in case there is a power outage and you need to use the ice to keep yourself cool until you can get to an air-conditioned space.
  • If your house is too hot and you’re able to drive somewhere close, spend some of the afternoon hours in air-conditioned spaces, such as a library, mall/store/cafe, movie theater, or community center.
  • Click here for additional ”Tips from readers on keeping cool without A/C” (NPR).
  • Conventional air conditioners (especially old window units) use a lot of energy (and are therefore expensive to operate). And every time we use air conditioners to cool interior spaces, we’re heating the planet up even more. Much better air conditioning technologies now exist, and even better ones may be available soon. One option to consider is having a “heat pump” installed (also known as a ductless mini-split system). These are much more efficient than traditional air conditioners, and there are tax incentives and rebates that you might be eligible for. Or in very dry climates, many people use evaporative “swamp” coolers rather than air conditioners. Whole-house attic fans can also help reduce the need for air conditioning. (Note: If you are replacing/getting rid of an old air conditioner, make sure that your HVAC company properly recovers and disposes of its refrigerants. A/C refrigerant emissions are a major contributor to global warming!)
  • Scroll down to the section below on “Design strategies and investments,” for additional suggestions for keeping your home cool.
  • Check on your neighbors and friends, especially elderly or disabled people and people who don’t have air-conditioning (or who are experiencing a power outage). Make sure they are not showing signs of dehydration, heat exhaustion, or heat stroke (see graphic above). If you have air conditioning and a little extra space, invite others who don’t have A/C to come over to your house. Or let others borrow or keep any extra fans you may have.
  • Share information about local cooling centers that are open in your community or county. Print and post/distribute that information at homeless shelters and service centers, senior centers, soup kitchens, food banks, and libraries (and through social media and community websites, e.g., NextDoor). Find out if there are local Mutual Aid groups or others who are helping distribute water or assisting people in need. If your town does not provide a cooling center (or a mobile cooling bus), contact your Mayor or city council or local emergency services department to request one, or help find a location that could serve as one (e.g., community center, church, etc.).
  • You could leave some bottles/gallons of water in front of your house, in a fully shaded area, with a sign letting people know they can take one if they need it. And you could donate non-disposable (and disposable) water bottles (or clean gallon jugs with caps) to a local homeless shelter or organization.
  • On days/nights with particularly extreme heat, if you are able, you could offer to pay for (or you could crowd-fund) an air-conditioned motel room for a homeless person or family or for people who don’t have air conditioning. Or make a donation to a homeless/low-income services group that is assisting people in your area or in a region that is even hotter.

Animals

  • Pets: Do not make pets stay outside (or in a dog house) if it’s cooler in your house. When they must be outside, make sure they can remain in full shade and have plenty of water (you could even fill a small kiddie pool for them to sit in or drink from). Do not walk dogs on artificial grass or on hot pavement (especially black asphalt, but on any pavement when it’s hot out); it will burn their paws. Do not leave pets unattended in your car without air conditioning running. Click here for information on hot weather safety (and signs of heat stroke) for pets. If you see someone else’s pet in distress or in danger, call 911 or your local Humane Society or ASPCA.
  • Livestock and horses: Give them plenty of water every day (making sure they never run out) and access to shaded and well-ventilated areas (with a good cross-breeze and if indoors, also fans, if possible). If they have no shade trees (or not enough to shade all of them throughout the afternoon) or a large-en0ugh shade shelter outside, put up some type of shade canopies (e.g. canvas carports) for them. Hose them off with cool water when you can, or provide ice blocks for them to lick, or sprinklers, wading pools, or water misters when possible.
  • Wildlife: Put a bowl of clean water out daily for wildlife in your area (ideally in both your front and back yards); thoroughly wash the bowl out every day, if possible. I like to use a light-colored ceramic (or white plastic) bowl that won’t absorb much extra heat. (Note: Absurdly, many outdoor hoses have lead in them. Buy/use a lead-free hose, or get drinking water directly from a faucet.) Don’t set out deep buckets of water that tiny animals could fall into and not be able to climb out of. You can also leave fruit and vegetable scraps and other healthy food out for wildlife. And if there is no shade in your yard, you could put up a shade canopy/sail or make a temporary shade shelter (e.g., with old sheets or large cardboard boxes). Shade as much of your paved areas as you can to reduce the heat absorption on your property. If you see an animal in distress or in danger, contact your local wildlife rescue group.

Plants & Trees

  • Water plants at their base (near the roots) early in the morning. (On especially hot days, they might also need some water in the evening, but don’t soak plants too much before night-time.) Young trees (and new plants, planted within the last couple of years) especially will need more watering during heat waves. Older, established trees may need some water every few days during heat waves.
  • Move potted (portable) plants to shadier areas or cooler areas (e.g. a shaded potting shed).
  • On especially hot/sunny days, you could put shade cloth over the most vulnerable plants, or shade them with an umbrella.
  • Put a few inches of mulch (e.g., grass clippings, fallen leaves, wood mulch) around the base of plants (and place mulch several inches away from the base of trees). Do not buy peat.
  • Do not prune (or fertilize) plants on hot days.
  • Crops can benefit from having solar panels placed between rows for shading.
  • Organically grown crops and plants (and native plants) have been shown to have greater resilience to heat than chemically-grown (and non-native) crops and plants.
  • Some plants will simply not be able to survive the increase in temperatures, and we’ll need to replace some plants with more drought- and heat-adapted plants over time.
  • You can find lots of additional tips regarding how to protect plants and trees during heat by doing an online search.

 

Design strategies and investments:

The tips above mostly cover immediate or short-term steps you can take to protect yourself and other living things from heat. Here are some design strategies and investments to consider, which require a little more planning or preparation:

  • Put thermal window coverings on your windows (e.g., thermal honeycomb blinds or shades), particularly on west- and south-facing windows.
  • Add shade trees, awnings, or overhangs to your property (particularly outside of west- and south-facing windows and over dark, paved surfaces).
  • Make sure your home has enough insulation (especially in the attic and walls). This will also help you during cold periods.
  • When it’s time to replace your roof, choose light-colored roofing (and/or solar roofing tiles, or solar panels to shade the roof).
  • When it’s time to repave your driveway (or pathways), choose a light-colored paving material or pavers (rather than black asphalt paving), or better yet, replace some paved areas with light-colored pervious materials or vegetation. (Also ask your city to use light-colored paving materials.)
  • When choosing a car, in addition to choosing an electric or hybrid vehicle, choose one that’s a light color (e.g., white, silver) so it will not absorb as much heat.
  • Do NOT use artificial turf (fake grass). It becomes incredibly hot, even hotter than black asphalt, in the sun. Replace astroturf with native or adapted drought-tolerant plants, groundcovers, or a clover lawn. Replace astroturf sports fields with real (but drought-tolerant) grass.
  • Solar photovoltaic panels can provide shade over roofs, pavement, and between rows of crops.
  • Consider getting an electric battery backup system for your home; ideally, this would be tied into a solar photovoltaic system to keep your power (and cooling) on during extended power outages. You can also get an electric/solar generator to use during power outages (or off grid).
  • When designing any new home (or building), designers should consider incorporating passive cooling techniques. One ancient, passive cooling technique is the “wind catcher” design. And some building materials, such as rammed earth, have thermal properties that help keep homes cool in summer and warm in winter.
  • There are SO MANY things we can all do (and our society, government, and industry must do) to try to stop global heating from getting worse. Please check out and commit yourself to some of our climate solutions in our other posts.

Re-Tree the World: Clean the air, slow climate change, plus…

photo by Erica Gies

Trees are life enablers and life protectors. They are air cleaners and oxygen makers, making it possible for us to breathe (i.e., live). They mitigate climate change by absorbing carbon dioxide; one tree can sequester up to 50 pounds of CO2 per year, and an acre of forest can absorb twice the CO2 produced by the average car’s annual mileage. Trees also filter some pollutants out of the water and soil, and they can prevent soil erosion and control flooding by absorbing stormwater and buffering storm surges. They provide habitat to many species. They provide shade (natural cooling, which reduces energy use for AC cooling). Some trees provide food (fruit and nuts), as well as medicines. Being near trees boosts our mental health and clarity. Their presence increases property values for homes and neighborhoods, and they contribute much-needed beauty to our world. So many benefits. Trees are life; trees enable life; trees save lives.

Despite all of the ways that trees contribute to (and are necessary for) our health and wellbeing, a recent study found that during the past 12,000 years of human civilization, humans have wiped out almost half of the trees on earth. Around 15 billion trees are cut down each year (to make wood products, pulp, and paper; to clear land for development, as well as for cattle grazing, palm oil plantations, and other agricultural uses; and to use as a heating fuel). (Click here for other Forest Facts.) We are destroying our own life support system. We are also losing millions of trees to drought and disease in some areas, and also to the growing number of severe storms (wind/ice) and wildfires, which are worsened by climate change and simultaneously contributing to climate change through additional carbon emissions, in a vicious cycle (AKA a feedback loop).

“You and the tree in your backyard come from a common ancestor. A billion and a half years ago, the two of you parted ways. But even now, after an immense journey in separate directions, that tree and you still share a quarter of your genes….”
— Richard Powers, The Overstory

“When we plant trees, we plant the seeds of peace and seeds of hope.”
— Wangari Maathai, founder of the Green Belt Movement

“The best time to plant a tree was 20 years ago. The next best time is today.”
– Chinese proverb

“In some Native languages the term for plants translates to ‘those who take care of us.’”
― Robin Wall Kimmerer, Braiding Sweetgrass

“In the case of trees, being old doesn’t mean being weak, bowed, and fragile. Quite the opposite, it means being full of energy and highly productive. This means elders are markedly more productive than young whippersnappers, and when it comes to climate change, they are important allies for human beings.”
― Peter Wohlleben, The Hidden Life of Trees

“We’re so good at clear-cutting mother trees; we always go for the biggest, oldest trees because they’re so valuable. And I’m saying, ‘No! We need to do the opposite!’ We need to save those trees. And the more trees we can protect around them, the better off they’ll be.”
— Suzanne Simard, author of Finding the Mother Tree: Discovering the Wisdom of the Forest

23208221_10155936458843007_9218184974786625536_n

First and foremost, we need to prevent deforestation (particularly of the few remaining ancient and old-growth forests, as well as rainforests, boreal forests, and coastal mangroves). And then we also need to reforest and regreen our world. We can start with our own yards, gardens, fields, open spaces, or towns. Resist plans to cut trees down in your yard or community (unless the trees are hazardous or diseased). Plant a tree, or two or three! Try to select trees that are native or climate-adapted to your region; fast-growing and fire-resistant trees are great, too (yes, there are trees that are less flammable and even fire-resistant, such as redwoods). You can also choose fruit or nut trees, flowering trees, and other trees that help feed pollinators.

You could also have a tree (or multiple trees in a forest) planted in someone’s name (i.e., “adopt” or “sponsor” a tree in their honor) as a gift for any occasion—through groups like One Tree Planted, The Nature Conservancy, Cool Earth, 8 Billion Trees, the Green Belt Movement, Arbor Day Foundation, Trees for a Change, etc.

[NOTE: If you celebrate Christmas and you traditionally mark the occasion with a cut-down (i.e., killed) xmas tree, how about starting a new tradition: you could buy or rent a living (potted and replantable) tree instead (do a web search for the words “living Christmas trees” or “live xmas trees” and your county name to see if there are places near you that offer these; or just go get a live, plantable tree from a nursery). Alternatively, you could put ornaments or lights on a tree that’s already growing in your yard. Or get creative and make (or buy) a wreath or a table/mantle garland decoration from evergreen trimmings, and forego having a xmas tree at all (gasp!). In a climate crisis (which is what we are in now), and with millions of trees being destroyed by massive wildfires, drought, deforestation/development, commercial logging and clear-cutting, disease, and climate-driven pests every year, I think it’s entirely fair and appropriate to question and reconsider some traditions (such as our Great Annual Xmas Tree Massacre) and start up some new ones. Don’t you? Regardless of what you choose to do (or not do) for Christmas, you can always make a donation to a reforestation group or a local tree-planting group (or plant a tree or three in the spring or fall). You will find a partial list of tree-related organizations below.]

imagesfscOne good way to reduce extreme deforestation (the clear-cutting of forests) is to look for FSC (Forest Stewardship Council) certified wood and paper products (or even better, 100% recycled paper products), as well as Rainforest Alliance-certified products (see logos to the right)—and of course reduce, reuse, and recycle all forest/paper products. Also avoid processed foods and other products that contain palm oil, whenever possible, as palm oil plantations are responsible for much of the deforestation in the world, particularly in Indonesia (where orangutans’ habitat is being decimated).

Earlier this year (2017), 1.5 million volunteers planted a record 66 million trees in 12 hours in the state of Madhya Pradesh in India. Reforestation “flash mobs” have been conducted in other areas, as well. Costa Rica has served as a model of strong reforestation efforts in recent years. In some parts of the world, groups are starting to use drones to plant seeds or saplings, to reforest areas more quickly and efficiently than can be done by hand (there have been articles on this in Fast Company and Wired magazine, among other publications). Note: Climate- and site-appropriate (native or adapted) trees should be selected when planting trees, and multiple species should be planted for biodiversity, to recreate natural forests as much as we can (monoculture/monocrop tree plantations are not the answer). Also, forests should not be planted over native, wild grasslands, which also sequester carbon.

There are many anti-deforestation efforts as well as local tree-planting and global reforestation organizations around the world, including:

Natural Mosquito Control and Effective, Least-Toxic Insect Repellents

With the 2016 spread of the Zika virus and its link to microcephaly, proper mosquito control became something that people wanted and needed to understand more than ever. [The Aedes mosquito can carry Zika; this CDC map shows the areas that have reported active transmission of Zika.] Some types of mosquitoes can also transmit malaria, West Nile virus, equine encephalitis, dengue fever, yellow fever, and other serious diseases in various regions of the world. (Other types of mosquitoes are also responsible for infecting dogs with heartworm.)

Climate change is almost certainly contributing to the increase in some tropical diseases, due to higher temperatures and more precipitation in many areas, in the tropics and beyond.  [Source: The Guardian]

mosquitoUnfortunately, conventional tactics for killing mosquitoes are not always effective, and they tend to be toxic. Zika can harm the development of fetuses and can harm some adults; meanwhile, exposure to toxic insecticides can harm everyone (including fetuses). It doesn’t make sense for society to accept that we should have to suffer from the long-term effects of slow poisoning (e.g., chronic and fatal illnesses) from insecticides and pesticides when less-toxic, effective alternatives exist. We cannot just “fog” the world in a cloud of insecticides to try to avoid Zika or other mosquito-borne viruses. Furthermore, the use of insecticides often backfires and has unintended consequences, such as killing other insects and animals that eat mosquitoes.

header-logoHere are some key excerpts from a very helpful article from Beyond Pesticides, which references information from an article in The Guardian:

“Aerial and ground applications of pesticides have long been used for mosquito control, but many believe that these methods fail to sufficiently control mosquito populations, [and that they] promote resistance and kill other species that would have acted as a natural predator to mosquitoes.

Dino Martins, PhD, a Kenyan entomologist, in an interview with The Guardian said that while pesticides can reduce the population of flying adult mosquitoes that transmit the virus, they will fail to deal with the epidemic that threatens to become a global pandemic, and warns that spraying landscapes is extremely dangerous.  ‘It is a quick fix but you pay for it. You kill other species that would have predated on the mosquitoes. You also create a mosaic of sprayed and unsprayed low densities of chemicals that fosters the rapid evolution of resistance.’

Already there is emerging resistance to insecticides among Anopheles mosquitoes. Additionally it is impossible to fumigate every corner of habitat where mosquitoes might breed.

According to Dr. Martins, the explosion of mosquitoes in urban areas, which is driving the Zika crisis, is caused by a lack of natural diversity that would otherwise keep mosquito populations under control, and the proliferation of waste and lack of disposal in some areas which provide artificial habitat for breeding mosquitoes.

The efficacy of adulticidal pesticide applications (aerial or ground spraying) has been called into question over the years. Further, the drifting spray impacts other non-target organisms like pollinators, birds, fish and amphibians. Commonly used mosquito pesticides like permethrin, resmethrin, naled and malathion are all associated with some measure of human and ecological health risks, especially among people with compromised immune systems, chemically sensitized people, pregnant women, and children with respiratory problems, such as asthma.

…Individuals can take action by eliminating standing water, introducing mosquito-eating fish, encouraging predators, such as bats, birds, dragonflies and frogs, and using least-toxic larvacides like bacillus thuringiensis israelensis (Bt). Through education of proper cultural controls, and least-toxic and cost effective biological alternatives, the use of hazardous control methods, such as toxic pesticides, can be eliminated.

  • Clean-Up–Eliminate pooled or stagnant waters from debris, containers, drains, and anywhere that pools water. Watch out for [and fix] leaky faucets. Mosquitoes can breed in puddles the size of dimes, so keep a keen eye out for stagnant water!
  • Natural Predators– Use indigenous fish populations, like bluegills or minnows, to eat mosquito larvae in shallow waters and ornamental pools. Copepod crustaceans can also be used to eat mosquito larvae in ditches, pools and other areas of stagnant water. Don’t forget about bats either! One bat can consume 1,200 mosquitoes in an hour, and many bats are in trouble from a disease wiping out their population. Help conserve these important mammals while keeping the mosquito population down by installing a bat house!
  • Behavior Modification–Wear long sleeves and long pants/skirts, and use least-toxic mosquito repellent when outdoors. Try to avoid being outside at dusk when mosquitoes are most active.
  • Attentive Monitoring– Check sources of water for signs of mosquito larvae often.
  • Least-toxic Pesticide Options– Use Bacillus thuringiensis israelensis (Bt), a biological larvicide (“mosquito dunk”) that prevents mosquitoes from developing into breeding, biting adults in standing waters that cannot be drained.
  • Take Action–Let your local council members, mayor, or state delegates know that safer, more sustainable options exist. [Click here and scroll to the bottom of the article to] download our sample letter to send to public health officials in your area.

Beyond Pesticides’ Mosquito Management program page has a list of resources that can help you and your community safely manage mosquitoes, including least-toxic mosquito repellents, bed nets, and proper clothing that can be used to keep mosquitoes safely at bay.”

In addition to the behavior suggestions mentioned above, these are some other useful suggestions for keeping mosquitoes (and other bugs) away:

  • Make sure any windows that get opened have window screens, and repair/tape any tears in the screens.
  • Turn on a fan. Mosquitoes avoid strong wind.
  • Remove all standing and stagnant water from your yard. Don’t let excess water sit in plant pot dishes. Clear out debris from gutters. Remove water from birdbaths, any discarded tires, unused water troughs, etc. If you use rain barrels, make sure they have screens and that the screens are on tightly. If you have a compost pile, make sure it has drainage, is not soggy, is covered with a thick layer of leaves or grass clippings, and is not located right next to your living quarters. Running/moving water is generally OK, as mosquitoes larvae cannot grow there.
  • Cover up with loose, light-colored clothing. Wear shoes and socks instead of sandals. Change and wash your socks and clothing regularly, as mosquitoes are attracted to stinky feet and sweat.
  • Use mosquito netting over baby carriers, strollers, beds, etc.
  • Avoid drinking beer or eating/drinking dairy products when in a mosquito-prone environment. They seem to be attracted to beer and possibly also to lactic acid.
  • Methods and products that don’t work or don’t work well include: 1.) Ultrasonic devices. 2) Vitamin B patches. 2.) Repellent candles (e.g., citronella candles): They don’t work nearly as well as clothing or skin treatments, and 3) Bug zappers: They may actually attract more mosquitoes and other bugs to the area, and they can kill beneficial bugs.

Repellents

There’s no need to coat your skin or clothes with highly toxic chemicals to avoid being bitten by mosquitoes. Studies are finding that mosquito repellents that use oil of lemon-eucalyptus (with some PMD) are just about as effective as DEET, and they last longer. Picaridin (or icaridin, or KBR 3020) is a less-toxic synthetic repellent than DEET and it works almost as well. The EcoSmart organic insect repellent (which uses a variety of botanical ingredients) was also found to work well, but it needs to be reapplied frequently (every 2-3 hours).  [Sources: NPR and EWG]

Consumer Reports gave these three DEET-free repellents their top ratings: Sawyer—Fishermen’s Formula Picaridin;  Repel—Lemon Eucalyptus; and Natrapel 8-hour. [For more information on those three products, see this article.] A friend of mine, who runs a summer farm camp and has tried many repellents, swears by All Terrain’s Herbal Armor repellent (which is also DEET-free).

Avoid using permethrin-based repellents, even those used to treat clothing and not applied to skin. Also avoid products with more than 30% DEET. And don’t use “foggers.” Those are all very toxic. Also, don’t use any aerosol sprays (use lotions or pumps instead). Don’t use repellents on babies under 6 months, and don’t use lemon-eucaluptus/PMD on children under 3 years old.  [Source: EWG’s Guide to Bug Repellents in the Age of Zika: Top Choices, and Do’s and Don’ts for Avoiding Bug Bites]

Other than lemon-eucalyptus oil, most botanical/plant-based repellents have not been found to be as effective as DEET or Picaridin-based repellents (especially for repelling the types of mosquitoes that can carry Zika). However, you could still experiment with rubbing a few of these bug-repelling plants on your skin or clothes (try a small area first, to make sure it doesn’t cause an allergic reaction). Better yet, planting some of these herbs and plants in your yard could help reduce the mosquitoes (and also fleas and ticks) in the area around your house. (Always be sure to buy organic—or non-treated—plants or seeds, so that they don’t kill off pollinators and other beneficial bugs and creatures.)  Turning your yard into a thriving garden will also help create more much-needed habitat for beneficial bugs, birds, and other species that help keep the mosquito population under control.

A company is currently working on developing Kite Patch and Kite Shield, technologies intended to prevent mosquitoes from detecting the CO2 that we emit, to make us virtually invisible to mosquitoes. Time will tell whether these technologies are effective. If they are, they are likely to become quite popular.

 

Unfortunately, many women who know that they got Zika during their pregnancy, or who live in areas where there are many Zika-carrying moquitoes, also happen to live in countries where contraception is not readily available or affordable, and/or where abortion is illegal and therefore unsafe.  Many such women are contacting organizations like Women on Waves for help.

Sustainable Agriculture, Farming, Gardening, and Food-Related Resources

This is a list of links to information resources related to sustainable agriculture, organic farming and gardening, and growing and buying good, safe food.

Image created by Matt FarrarThese resources are organized into the following general categories (though some are relevant to more than one category): Organizations, Magazines and Blogs, Educational Programs, Funding & Investing, Permaculture, Urban Farms, Agri-Tourism / Farm Tours, International/Non-U.S. Initiatives, Films and Books.

At the end, you will find a few suggestions of simple ways to get involved in the good food movement.

Organizations

Magazines and Blogs

Educational Programs

Funding and Investing

(including some crowdfunding sites)

Permaculture

[Partial list; please mention other groups in the Comments.]

Urban Farms

[This is just a small selection; there are many, many more. Please mention other urban farms you are familiar with in the Comments.]

Agri-Tourism / Farm Tours

International/Non-U.S. Initiatives

Films and Books

Many films about food and farming have come out recently. One of the most recent is Symphony of the Soil.

There are also many books on these topics. One new one is called Farmacology: What Innovative Family Farming Can Teach Us About Health and Healing, by Daphne Miller, MD.  Another recent book is Farmer Jane: Women Changing the Way We Eat, by Temra Costa.

I also recommend reading Barbara Kingsolver’s Animal, Vegetable, Miracle, as well as books by Wendell Berry, Michael Ableman, Michael Pollan, Frances Moore Lappe, Anna Lappe, and Marion Nestle.

For other relevant books, check out the offerings from Chelsea Green Publishing, Mother Earth News, and New Society Publishers.

Taking Part

You don’t have to be a farmer to be involved in sustainable agriculture and the good food movement. Here are just a few of the steps that almost anyone can take, to create a healthier family, healthier community, and a healthier planet:

  • Buy organic, non-GMO, and locally grown foods whenever possible (from the grocery, a farmer’s market, local farms, a CSA, etc.) To find local farms, farmer’s markets, or food providers, go to LocalHarvest.org, and if you live in California or New York, check out Farmigo.com, which is basically an online Farmer’s Market or CSA for small or large groups.
  • If/when you buy meat (from stores or at restaurants), avoid getting factory-farmed meats. Look for and ask for meats from grass-fed and grass-finished animals, that are free of antibiotics and added hormones, and that also, ideally, have third-party certifications (such as Animal Welfare Approved) verifying that the animals were raised and slaughtered humanely. Boosting the demand for such products will help shift the industry away from factory farming. (We’ll be adding a blog post with more information on humanely raised meat in the future.)
  • Buy organic, non-GMO seeds and organically grown plants, and plant them in a kitchen garden, window boxes, porch pots, raised beds, a greenhouse, a community garden, or wherever you can.  Use organic/natural rather than toxic chemical pesticides, herbicides, and fertilizers. It’s fun and satisfying to swap your surplus harvest with friends and neighbors.
  • Replace water-intensive, conventional grass lawns with a garden, or no-mow native grasses or groundcovers. Choose low-water (drought-tolerant), native or adapted (climate-appropriate) plants and flowers, including those that attract and feed pollinators such as bees and butterflies.

Tips for Conserving Water

Conserving water is becoming increasingly important, and it has become a necessity in areas that are suffering from drought. According to the UN, by 2025, 1.8 billion people will be living in countries or regions with absolute water scarcity, and two-thirds of the world’s population could be living under water-stressed conditions, as a result of water shortages from climate change and rising levels of water use due to a growing population.

Reducing your water use will not only lower your water bills and help prevent potential water shortages. It also reduces the strain on municipal water systems and infrastructure (e.g., sewer, water treatment and distribution), which helps reduce the energy, maintenance, and the associated taxes required to run and expand those systems. Using less water can also save you money on your energy bill, because electricity or gas is used to heat your water. Water conservation also leaves more water available for critical uses, such as drinking, growing food, and fighting fires; and it keeps more water in lakes, rivers, and streams for aquatic species and other wildlife.

These are some of the ways that you can reduce your household water use, both indoors and outdoors:

INDOORS:

  1. Replace your toilets, faucets, and showerheads with high-efficiency (WaterSense labeled) plumbing fixtures, or at least add aerators to your faucets, and if you have an old toilet, put a small water bottle (filled with water, with the cap on) into the toilet tank for displacement. Switching to high-effiiency fixtures results in significant water savings.
  2. Do not let faucets run longer than is necessary for your task. Don’t leave it running while brushing your teeth, shaving, or soaping up your hands or dishes. And when you turn a faucet off, make sure that it is turned all the way off.
  3. Try to take short showers, and/or don’t take a shower every day (if you aren’t really dirty—from work, exercise, recreation, etc.).
  4. When using a clothes washer or dishwasher, only wash fairly full loads (or select a light-load setting for small loads). If you’re buying a new washer, select a high-efficiency (Energy Star) and water-saving model. Front-loading washing machines are much more efficient than top-loading machines.
  5. Wash dirty dishes immediately or soak them before hand-washing, so that they can be washed off more easily and quickly (requiring less water).
  6. If a faucet is dripping or if your toilet is running (for too long after it has been flushed), have the leak fixed right away. A leaking toilet can waste more than 50 gallons of water each day, and a dripping faucet or showerhead can waste up to 1,000 gallons of water per week (according to ResourceVenture.org). Also check for washing machine or dishwasher leaks (usually found where the hose is connected to the machine or at the shut-off valve). Familiarize yourself with the water shut-offs behind your toilet, sinks, and washing machine, as well as the water shut-off for the entire house, so that you know how to turn off the water when needed.
  7. As the saying goes, “If it’s yellow, let it mellow. If it’s brown, flush it down.” There’s generally no need to flush a toilet after it’s only been peed in one time. Hold off on flushing until the toilet has been peed in 2-3 times or has been used for “doing #2.”
  8. Compare your water bills (or water meter readings) from month to month and from year to year, to monitor the results of your conservation efforts and to look for any sudden spikes in water use, which could be caused by leaks.

OUTDOORS (yard / lawn / garden):

  1. Water your yard/garden during the coolest, least windy, and/or least sunny time of the day (usually overnight or early morning, ideally after midnight / before dawn) to avoid losing a lot of water via evaporation. And be sure to avoid over-watering; many plants do not need to be watered every day, and some rarely need to be watered at all.
  2. When you add new plants, trees, or other vegetation, select drought-tolerant or native/adapted plants that require little, if any, irrigation. To get information on how to choose the best plants for your area, click here.
  3. Putting mulch (including fallen leaves or wood chips) on your garden or landscaped areas can help the soil retain moisture longer.
  4. Turf grass typically requires much more water than groundcover or shrubs, so the less lawn area you have, the less watering you will need to do. If adding or reseeding grass areas, select a drought-tolerant, native grass variety or consider replacing the grass area with groundcover or native plants. As an added bonus, most types of groundcovers and some types of grasses will only grow a few inches tall, so they would rarely if ever need to be mowed.
  5. If you are installing an irrigation system, choose a high-efficiency irrigation system. Drip, micro, and bubbler irrigation systems are more efficient than spray or sprinkler irrigation, because they deliver water directly to plants’ roots, minimizing evaporative water loss. If you use a hose to water, use a shut-off/trigger nozzle on it so that the hose doesn’t continue to run when it isn’t aimed at the plants to be watered.
  6. If you have an irrigation system or sprinklers, make sure that all spray or drip spouts are oriented in such a way that they are watering planted areas only and are not watering the sides of buildings, pathways or other paved areas. In addition to wasting water, allowing water to pool up on pavement can make it slippery to walk on an can degrade the pavement over time.
  7. Also, for irrigation systems, perform (or have an irrigation specialist perform) regular system checks and maintenance, to make sure there are no leaking heads, pipes, or valves. Make sure the irrigation system is not watering the lawn/yard/garden during (or immediately preceding or following) rainy days. Even on dry days, make sure the system is not over-watering the plants or over-saturating the soil. If the irrigation timer runs on a battery, make sure it is working and change the battery as needed; if the battery is dead, the system could allow non-stop watering (which would waste a lot of water). Re-program the system seasonally and as necessary to adjust to weather conditions. Winterize the system before the first frost of each year. If issues arise, consider hiring an irrigation professional to do an irrigation audit.
  8. Consider adding rainwater collection barrels/tanks at downspouts (or a bucket in your shower or yard, or a greywater system) for use in watering your yard/garden.
  9. Sweep your sidewalks and driveway (and other paved areas), rather than hosing them down.
  10. Avoid washing your car frequently, and if/when you must wash it, take it to a carwash that recycles its water.

At a broader level, two of the most effective ways to reduce water use (indirectly but significantly) are: to reduce your energy use (because the generation of electricity typically requires enormous amounts of water), and to reduce or eliminate your consumption of meat (because raising meat animals, especially corn-fed factory-farmed beef cows, requires enormous amounts of water) as well as your consumption of milk and other dairy products (and also non-dairy soy milk, almond milk, and rice milk), which are also water-intensive to produce.

Flea and Tick Treatments That Won’t Poison Your Pet

Fleas and ticks (and mosquitos) can bring severe itching, allergic reactions, discomfort, and even serious diseases (such as lyme disease) to your pets, so it’s important to protect your pets from them. However, studies have found that some common flea and tick control treatments—products that are readily available at stores and have been recommended by many vets—aren’t just harmful to fleas and ticks; they can actually poison pets, and some are also dangerous to humans and other animals.

Some conventional flea and tick treatments (including many of the topical, spot-on treatments that are applied directly onto pets’ skin, as well as flea collars, powders, and sprays, and even some ingestible products) contain highly toxic pesticides, some of which have been shown to cause a range of serious reactions in pets, from skin problems, vomiting, and excessive drooling to neurological problems (e.g., seizures or uncontrollable shaking), heart attacks, and death. So, tragically, some pesticides end up serving as pet-icides…

The Center for Public Integrity did a study in 2008, and found that at least 1,600 pet deaths related to spot-on treatments were reported to the EPA over the previous five years. According to the NRDC, cats may be more susceptible to adverse reactions than dogs, since they are more likely to lick the treatments off of their fur and they often lack enzymes for metabolizing or detoxifying the pesticides. Many of these pesticides are toxic to humans, as well, and children are especially vulnerable to exposure.

Avoid products that contain pyrethroid, pyrethrin, or permethrin pesticides, organophosphate insecticides (such as tetrachlorvinphos/TCVP; chlorpyrifos, dichlorvos, phosmet, naled, diazinon, and malathion), carbamates (e.g., propoxur, fenoxycarb, and carbaryl), or Amitraz. [This list was updated on May 26, 2010.] Many common flea/tick control products contain at least one of these ingredients. (Towards the end of this post, you will find a link to a listing of some specific products to avoid.) Please note: Never use products on cats that are meant for use on dogs (and vice versa), and never give your pet more than the recommended dose.

It’s disturbing that so many of us might have been unwittingly sickening our animals (and possibly shortening their lives) by using these products, often at the recommendation of our veterinarians, who trusted the manufacturers’ assurances of the products’ safety. It’s yet another example of how you can’t trust that a product is safe just because it’s been allowed into the marketplace. According to the Humane Society, the EPA did not start reviewing pet products for safety until 1996, and there is still a backlog of products that need to be tested. However, the overarching problem is that some ingredients that the EPA had deemed “safe” clearly were not. In 2009, the EPA announced that it would be developing stricter testing and evaluation requirements and could place new restrictions on flea and tick products.

Fortunately, there’s no need to wait for those changes to take effect. Safe and natural alternative products and methods for controlling fleas and ticks already exist. Here is some guidance from the NRDC on ways to prevent flea problems. And when treatments are necessary, some pet supply stores and many online sites (see links below) now carry flea and tick products that are made up of plant-based ingredients, such as peppermint oil, citrus oil, clove oil, or Neem, which is a natural insecticide that comes from a tree. See the NRDC’s Flea and Tick Product Directory to look up the ingredients and risks of specific products. Some flea and tick solutions can even be made at home. Fleas and ticks are repelled by rosemary, thyme, eucalyptus, and lavender. So to ward off the bugs, you can tuck sprigs of one or more of those plants under your pet’s bed cover (or under your rugs), or boil some of those herbs in water and pour the cooled water onto your pet, rubbing it into their coat. (Note: Some herbal or “natural” ingredients can cause allergic reactions or toxicity in animals. Be sure to test any treatment in a small dose first; and always apply treatments sparingly and only as needed. Also, never use pet products that contain pennyroyal oil, which is toxic to animals. Furthermore, while some sources say that adding a little bit of garlic to a pet’s diet will repel fleas, other reputable sources say that garlic can be toxic to dogs and even more so to cats, even in small amounts; so I steer clear of using garlic, just to be safe.) If your pet has a flea infestation that does not respond to any of the plant-based solutions listed above, look for the lowest-risk commercial products listed in the NRDC’s directory, which include Spinosad-based products, such as Comfortis.

NRDC’s research has identified many common products that should be avoided, due to their high toxicity risks. According to the NRDC, such high-risk products currently include K9 Advantix II, and a number of products made by Hartz, Sentry, Sergeant, Vet-Kem, Adams, Bio Spot, Happy Jack, Verbac, Zodiac, and other companies.

To take action on this issue, print out some of the info from the links below, bring it to your pet store and to your veterinarian, and ask them to stop selling flea control products that contain the most dangerous pesticides (and to start selling the lowest-risk products), to protect the health of pets and their people.

Sustainable Ag: Marin and Sonoma County Resources

This is an addendum to the previous post for those of you who live in (or near) Marin or Sonoma County, California.

ca-seedbank-store-frontWe are fortunate to have a plethora of amazing farms and sustainable agriculture resources in this area. One very cool new addition to our local scene is the “Seed Bank” store, located in a historic bank building at a major intersection in downtown Petaluma (Washington and Petaluma Blvd.). The store sells more than 1,200 varieties of non-GMO Baker Creek Heirloom Seeds.

Our area is also home to many farmers markets, as well as wonderful organizations (and businesses) such as:
Marin Organic :: MALT (Marin Agricultural Land Trust) :: Grown in Marin :: Petaluma Bounty :: Sonoma County Farm Trails :: Occidental Arts and Ecology Center :: Ag Innovations Network :: Harmony Farm Supply & Nursery ::  Mostly Natives Nursery :: Permaculture Skills Center [NEW: Added 2014] :: F.E.E.D. Sonoma Farmers Exchange [NEW]

You might also want to check out the Hidden Bounty of Marin, a recently produced 1/2-hour film about the farms and farmers of beautiful West Marin; it shows the rich variety of agricultural enterprises in this region—from dairy, produce, and oyster farming to cattle, hog, and sheep ranching.

There are many great family farms in this area. Wild Blue Farm, Toluma Farms (goat dairy), and Straus Family Creamery are some of my favorites, as they’re the farms that I’m most familiar with.

And lastly, here’s my list of links to other sustainability-related resources in the North Bay region of the San Francisco Bay Area. If you have other favorite local organizations or resources to recommend, please share them in the Comments section below. Thanks!
