EARTH TALK
From the Editors of E/The Environmental Magazine

 

Dear EarthTalk: My pediatrician swears by those gel hand sanitizers for lowering the risk of my family getting sick during cold and flu season. But I’ve also heard that these products can be dangerous to kids if ingested. Are there any safer alternatives that work just as well?                                                                                                                                                -- Jason Blalock, Oakland, CA 

A 2005 study by the Children’s Hospital in Boston compared illness rates across a study group of 292 families—half of them got hand sanitizers while the other half were given literature advising them of the benefits of frequent hand washing. The findings revealed that those families who used hand sanitizers experienced a 59 percent reduction in gastrointestinal illnesses and that the increased use of sanitizers correlated to a decreased spread of contagions in general. 

Another study conducted at Colorado State University yielded similar conclusions, that alcohol-based hand sanitizers were as much as twice as effective as either regular soap or antibacterial soap at reducing germs on human hands. A Purdue University study, however, concluded that while alcohol-based hand sanitizers may kill more germs than plain or triclosan-based soaps, they do not prevent more infections that make people sick. Instead they may kill the human body’s own beneficial bacteria by stripping the skin of its outer layer of oil. 

The down side of the gel/alcohol products is their danger as poison, especially for young children who may ingest the gel by licking it off their hands or eating it directly out of dispensers. Purell and Germ-X, two of the leading brands, each contain 62 percent ethyl alcohol. While this alcohol is what gives the products their germ-busting power, it also puts kids at risk of alcohol poisoning. A few squirts of the hand sanitizer—which is equivalent to124 proof booze—is enough to make a kid’s blood alcohol level .10, which is the equivalent of being legally drunk in most states. 

So what’s a concerned parent to do? Unfortunately, the so-called greener alternatives out there aren’t safe to swallow either. EO Hand Sanitizer, for example, though it uses organic lavender oil also contains alcohol to sanitize the skin surface, and would also be considered poison if a large enough amount was ingested. Similarly greener (but still not safe to eat) products are available from Avant and All Terrain. 

For now, soap and warm water—and constant nagging of your kids to wash their hands—may be the safest way to sanitize. Also, make sure that any hand sanitizer dispensers you may still use are kept out of the reach of little hands. 

But who knows how we’ll be sanitizing our hands in the future. Researchers at Arizona State University have found that certain types of natural clays pulled right from the ground are highly effective at killing bacteria. One type of green clay has been shown to do a number on E. coli, salmonella, staph and other bacteria known to make people sick. But the research is still in its infancy, so don’t expect to see moms pulling jars of clay out of their purses anytime soon.

EARTH TALK
From the Editors of E/The Environmental Magazine

 

Dear EarthTalk: What are the environmental consequences of leather? Are there any good alternatives?                                                                                          -- Brianna Jacobs, Somerville, MA

 

Leather is everywhere—from shoes and belts, to purses, wallets, jackets, furniture and car seats. Most probably assume that the leather that finds its way into our wardrobes and living spaces is a byproduct of the meat industry. But while cows are certainly the most popular animals to use for leather goods, in truth most of our leather is sourced from overseas, from countries like China and India, where a host of animals may be raw material for our bags and belts, including horses, deer, sheep and, in more exotic cases, alligators or snakes. All of which may make an animal-lover or vegetarian queasy.

 

But environmentalists have reason to forgo leather, too. Processing leather requires copious amounts of energy and a toxic stew of chemicals including formaldehyde, coal tar, and some cyanide containing finishes. The tanning process is just as pollutant-laced, and can leave chemicals in the water supply (as described in the best-selling book and popular movie, A Civil Action) and on the hands (and in the lungs) of developing world workers.

 

Tanneries are top polluters on the Environmental Protection Agency’s (EPA) “Superfund” list, which identifies the most critical industrial sites in need of environmental cleanup. Due to their toxicity, reports organicleather.com, “many old tannery sites can’t be used for agriculture, or built on, or even sold.” That website is the home of Mill Valley, California, retailer Organic Leather, which offers a return to the tanning practices of old—using animals that are organically fed and humanely raised and a tanning process that uses plant tannins, vegetable tannins or smoke to cure the leather with zero toxicity in the process.

 

But with the wealth of fashionable faux leather alternatives, there’s no need to ever wear animal skins. So-called “cruelty-free” fashions have advanced in leaps and bounds, with variations on every style of handbag, wallet, belt and boot. Online “vegan boutique”Alternative Outfitters even has a version of the ubiquitous Ugg boot made with microsuede “shearling” on the outside and synthetic wool inside, while Iowa-based Heartland Products sells western-style non-leather boots and non-leather Birkenstock sandals. Science has come up with plenty of comfortable, durable alternatives to materials made with animal products. These include vegan microfiber, which claims to match leather in strength and durability, and Pleather, Durabuck and NuSuede.

 

Products made with these synthetic materials tend to be less expensive than their leather counterparts and are being produced by major manufacturers like Nike, whose Durabuck athletic and hiking shoes “will stretch around the foot with the same ‘give’ as leather... and are machine washable,” according to company sources. And you won’t need to adjust your style, either. Vegetarianshoesandbags.com offers everything from purple faux snakeskin peep-toe pumps for hitting the clubs to hemp sneakers with recycled outsoles that look skate park-ready, to distinctive Pleather bags and versatile woven belts.

EARTH TALK
From the Editors of E/The Environmental Magazine

Dear EarthTalk: What are some of the best online sources of environmental information?                                                                                                                                     -- Hip2bGreen, Seattle, WA

 One of the best places to start in venturing out into eco-cyberspace is the website of a green group you already know—perhaps one for whom you have donated money or volunteered. Most groups use their websites to keep their supporters updated on the issues they cover, and provide links to many other green websites. Beyond such groups, several independent “third-party” sources also provide useful information on a wide range of environmental topics, from consumer tips to news to action alerts. 

One leading green website is Grist (grist.org), which reports environmental news in a witty and engaging manner, billing itself as “gloom and doom with a sense of humor.” Checking out Grist’s daily rundown of environmental news is de rigueur among eco-activists, and many regular folks keep tabs on it, too. Other excellent news sources include Environmental News Network (enn.com), and Environmental News Service (ens-newswire.com). And one new kid on the block is The Daily Green (thedailygreen.com), which bills itself as the “consumer’s guide to the green revolution.” Owned by major magazine publisher Hearst, The Daily Green offers news, green tips and advice, and a plethora of green home, food and lifestyle topics. 

The Green Guide (thegreenguide.com), run by National Geographic, is probably the best online source for green consumer information, specializing in green living tips, product reviews and environmental health news. Looking for guidance on saving water around the house, choosing among non-toxic paints or packing greener lunches for your school-age kids? The Green Guide would be a good place to start. 

If you’re interested in more comprehensive looks at green issues and topics, emagazine.com posts much of the content of its flagship E – The Environmental Magazine, along with weekly news and commentary. Visitors can also access 18 years worth of in-depth articles—the magazine has been turning out bi-monthly print issues since 1990—on just about every green topic imaginable. 

Those interested in social networking and the environment should look to Care2 (care2.com), the world’s largest online environmental community. The site offers its eight million members free e-mail accounts and provides lots of background information on just about every environmental issue.

 A handful of green ‘blogs are starting to get a lot of media attention and web traffic. The king of them all is Treehugger (treehugger.com), which offers several posts each day from a stable of thinkers committed to environmental issues. Its coverage is not comprehensive, but Treehugger excels at tapping into trends in environmental thinking and culture. Another source of environmental tips and culture online is IdealBite (idealbite.com), a blog-style site offering up “bite-sized ideas for light green living.” 

And then there are the “click-to-donate” websites, where visitors can read up on a variety of conservation campaigns and then contribute money via credit card. Ecology Fund (ecologyfund.com), the Rainforest Site (the rainforestsite.com) and Red Jellyfish (redjellyfish.com) are some of the leaders in this category. 

So cue up that browser and start clicking. You’ll be amazed at what you can learn, let alone accomplish! 

Dear EarthTalk: What is the status of sharks around the world? I see occasional stories about sharks attacking humans, but on balance aren’t we a lot more brutal to them then they are to us?                                                                                                                         -- Pam Hitschler, Radnor, PA 

It’s true that humans do a lot more damage to shark populations than vice versa. Marine biologists report that sharks are in rapid decline around the world. In the North Atlantic Ocean, shark populations have declined more than 50 percent over the past 20 years alone, with some species now nearing extinction. 

Experts see the primary cause as overfishing, which depletes sharks as well as their prey. Sharks are especially vulnerable to illegal “longlines” (fishing nets strung across dozens if not hundreds of miles of ocean), where they get inadvertently snared along with the tuna and swordfish fishermen intend to catch. 

Rising demand for shark fin soup in is also contributing to the demise of sharks. According to a report by Wildaid, shark fins are among the most expensive seafood products in the world, selling for some $700 per kilogram on the Hong Kong market. With prices like that, many longline fishermen, who are already operating illegally, are happy to augment their incomes by “finning” a few sharks along the way. (Finning is the practice of removing a fin from a shark and discarding the rest of the carcass at sea.) 

Often, threatened wildlife species manage to maintain their numbers in spite of excessive human predation. But sharks face an especially uphill battle, says renowned shark expert Ransom Myers, because they “take a long time to mature and have relatively few babies.” 

So what is being done to save sharks? In the U.S., the Magnuson-Stevens Fishery Conservation Act is the primary law that oversees the conservation of U.S. fisheries and has established various management regulations for 39 species of sharks in the Atlantic Ocean, Caribbean Sea and Gulf of Mexico. It outlaws finning if the carcass is discarded but not if the rest of carcass is kept, clearly an unfortunate loophole. 

The U.S. also helped develop a United Nations Food and Agriculture Organization treaty (the International Plan of Action for the Conservation and Management of Sharks) whereby 87 countries agreed to develop their own plans for the conservation of sharks. However, only two countries—the U.S. and Australia—have lived up to the agreement. The U.S. plan is administered by the National Oceanic and Atmospheric Administration, which has been working with regional fisheries authorities to make sure fishermen are sticking to cautiously low quotas regarding the number of sharks they are allowed to catch. 

What can consumers do to save the sharks? The Monterey Bay Aquarium in Monterey, California urges consumers to avoid all shark products, not just on restaurant menus but also all souvenirs such as jaws and teeth, and shark-cartilage pills, which have been touted as cancer cures but which have been proven to be completely ineffective and are now widely considered a scam. The aquarium also encourages consumers to support with their pocketbooks conservation groups working to protect sharks and oceans, and specifically those working to set aside marine reserves that are off-limits to fishing.
