Researchers have found that children who play outside more are in better shape, more creative, less aggressive and show better concentration than their couch potato counterparts.

Getting kids away from computer and TV screens and outside into the fresh air is an increasing challenge for parents everywhere. Researchers have found that U.S. children today spend about half as much time outdoors as their counterparts did 20 years ago. The Kaiser Family Foundation reports that kids aged eight to 18 spend on average more than seven and a half hours a day – or some 53+ hours per week – engaging with so-called entertainment media. Meanwhile, the Children & Nature Network (C&NN), a non-profit founded by writers and educators concerned about “nature deficit disorder,” finds that, in a typical week, only 6 percent of American kids aged nine to 13 plays outside on their own.

According to Richard Louv, a founding board member of C&NN and author of the book, Last Child in the Woods, kids who stay inside too much can suffer from “nature deficit disorder,” which can contribute to a range of behavioral problems including attention disorders, depression and declining creativity, as well as physical problems like obesity. Louv blames parental paranoia about potential dangers lurking outdoors and restricted access to natural areas – combined with the lure of video games, websites and TV.

Of course, one of the keys to getting kids to appreciate nature is for parents to lead by example by getting off the couch and into the outdoors themselves. Since kids love being with their parents, why not take the fun outside? For those kids who need a little extra prodding beyond following a parent’s good example, the National Wildlife Federation (NWF), a leading national non-profit dedicated to preserving and appreciating wildlife, offers lots of suggestions and other resources through its Be Out There campaign.

One tip is to pack an “explorer’s kit” – complete with a magnifying glass, binoculars, containers for collecting, field guides, a notebook, bug repellent and Band-Aids® – into a backpack and leave it by the door to facilitate spontaneous outdoor adventures. Another idea is to set aside one hour each day as “green hour,” during which kids go outside exploring, discovering and learning about the natural world.

NWF’s online Activity Finder helps parents discover fun outdoor activities segmented by age. Examples include going on a Conifer Quest and making a board displaying the different types of evergreen trees in the neighborhood, turning an old soda bottle into a terrarium and building a wildlife brush shelter.

Researchers have found that children who play outside more are in better shape, more creative, less aggressive and show better concentration than their couch potato counterparts – and that the most direct route to environmental awareness for adults is participating in wild nature activities as kids. So do yourself and your kid(s) a favor, and take a hike!

Smoking and poor nutrition together account for two-thirds of U.S. cancer deaths each year, but the President’s Cancer Panel reported in 2010 that environmental toxins play a significant and under-recognized role in many cancers, causing “grievous harm” to untold numbers of Americans.
Dear EarthTalk: I know that some of us are genetically predisposed to get cancer, but what are some ways we can avoid known environmental triggers for it? – B. Northrup, Westport, MA

Cancer remains the scourge of the American health care system, given that four out of every 10 of us will be diagnosed with one form or another during out lifetime. Some of us are genetically predisposed toward certain types of cancers, but there is much we can do to avoid exposure to carcinogens in our environment.

According to the Environmental Working Group (EWG), a non-profit working to protect public health and the environment, a key first step in warding off cancer is lifestyle change – “stopping smoking, reducing drinking, losing weight, exercising and eating right.” The American Cancer Society reports that smoking and poor nutrition each account for about one-third of the 575,000 U.S. cancer deaths each year.

But smoking and obesity are obvious and other cancer triggers aren’t so easily pinpointed. In 2010 the President’s Cancer Panel reported that environmental toxins play a significant and under-recognized role in many cancers, causing “grievous harm” to untold numbers of Americans. And EWG reports that U.S. children are born “pre-polluted” with up to 200 carcinogenic substances already in their bloodstreams.

Given this shocking fact, it may seem futile to try to reduce our bodies’ chemical burden, but it could be a matter of life and death. EWG lists several ways anyone can cut their cancer risk. First up is to filter our tap water, which can include arsenic, chromium and harmful chemicals. Simple carbon filters or pitchers can reduce contaminants, while more costly reverse osmosis filters can filter out arsenic or chromium.

The foods we choose also play a role in whether or not we get cancer. Eating lots of fruits and vegetables is healthy, but not if they are laden with pesticides. Going organic when possible is the best way to reduce pesticide exposure. And when organic foods aren’t available, stick with produce least likely to contain pesticides (check out EWG’s “Clean 15” list of conventional crops containing little if any pesticide residue). EWG also suggests cutting down on high-fat meats and dairy products: “Long-lasting cancer-causing pollutants like dioxins and PCBs accumulate in the food chain and concentrate in animal fat.”

Eliminating stain- and grease-proofing chemicals (Teflon, Scotchgard, etc.) is another way to cut cancer risks. “To avoid them,” says EWG, “skip greasy packaged foods and say no to optional stain treatments in the home.” And steer clear of BPA, a synthetic estrogen found in some plastic water bottles, canned infant formula and canned foods. “To avoid it, eat fewer canned foods, breast feed your baby or use powdered formula, and choose water bottles free of BPA,” reports EWG. Personal care products and cosmetics can also contain carcinogens. EWG’s “Skin Deep” cosmetics database flags particularly worrisome products and green-lights others that are healthy.

Another cancer prevention tip is to seal wooden outdoor decks and playsets. Those made before 2005 likely contain lumber “pressure-treated” with carcinogenic arsenic in order to stave off insect infestations. Of course, avoiding too much sun exposure-and wearing high-SPF sunscreen-when using those decks and playsets is another important way to hedge one’s bets against cancer.

  1. Yet Steingraber says that the report isn’t all bad news. “There’s good news here,” she says. What would be devastating is if cancer were mostly attributable to genetics — ”… because there would be nothing we could do about that except wait for our genes to blow up inside of ourselves,” Steingraber says. Instead, the report highlights the fact that some cancers are caused by things that we can do something about.
