A 2004 poll estimated that thirteen percent of American households keep goldfish. Nearly 500 million are sold each year just to feed other pets. How goldfish became America’s go-to pet is a matter of some debate.

Azure Crescendo

Bluebirds reside in tree cavities or manmade nestboxes.
Photo by Francie Von Mertens.

Generations ago, when people lived closer to the natural world, more outdoors than in, mild October days were called "bluebird weather. "The eastern bluebirds' gentle, quizzical notes were familiar and their distinctive habits recognized. A bluebird family remains together this time of year when most other bird species disperse. They favor field or open habitat, and typically perch on branches at field edge when they feed. Family members take turns dropping down to the ground then return to perch, one after another, most likely in pursuit of grasshopper or cricket.

How Safe Is Cat Litter

Many cat litters contain significant amounts of silica dust, chemical fragrances and, in "clumping" cat litters, sodium bentonite clay, derived from destructive strip mining and can cause gastrointestinal distress in cats that can lead to death.

American Consumption Habits

With less than 5 percent of world population, the U.S. uses a third of the world’s paper, a quarter of the oil, coal and aluminum, and 19 percent of the copper. The U.S. ranks highest by a considerable margin in most consumer categories as well.

Safer Sunscreens

Most of us assume that all we need do to prevent sunburns and skin cancer from exposure to the sun is to slather on sunscreen. But consumers should be careful about which sunscreens they trust for themselves and, even more important, for their kids.

Baggage-laden Biofuels

Biofuels (or agrofuels) can be a carbon-neutral energy source, but the overall process of producing them is far from carbon neutral, given the substantial amount of fossil fuels expended in growing, harvesting, processing and distributing them.

A Rare New England Bird May Actually Be Endangered

The Bicknell's thrush nests in mountain areas which are often tough for humans to cross, so they're not often seen by birders.

The Bicknell’s thrush is a migratory songbird that winters in the Caribbean but comes to northern New England to breed.

It's long been hard to find in the region – and conservationists say that’s becoming a big problem. In fact, the US Fish and Wildlife Service announced last week it’s considering the Bicknell’s thrush for endangered species status.

Anders V/ Flickrs Creative Commons

We talk with Pulitzer Prize winning author Edward Humes about his new book, Garbology: Our Dirty Love Affair with Trash. Americans are at the top of the heap for producing waste: over 100 tons per person in a lifetime.

Humes explores why we make so much garbage, the environmental and economic impact of trash…and why he believes this is a problem ordinary people can fix.
