The "Green Scissors" campaign

Green Scissors was launched to call attention to programs that both harm the environment and waste tax dollars, including environmentally damaging public lands, water projects, agricultural and fossil fuel subsidies.

Goldfinches, The Late Nesters

Courtesy byard via Flickr/Creative Commons

The bird world quiets down by late summer - but not the American goldfinch, one of the most common backyard birds. September brings the chatter of young goldfinches as they follow their male parent. They beg noisily, perched with head thrown back and trembling wings.

Most songbirds switch their diet to high-protein insects when feeding their young, and they nest earlier when insects are most bountiful. For example, chickadees that keep bird-feeders busy in winter disappear in summer as they forage for insects not birdseed.

Comments from Mt. Monadnock

This stream-of-consciousness postcard was assembled from random entries in the Marlboro Trail hiker register on Mount Monadnock, most-climbed mountain in the Western Hemisphere. A year of scrawled fragments…

Winter:

  • Happy New Year!
  • Today is my half-birthday!
  • Lost crampons on hike, if found please call…
  • Played hooky from work, a great choice.
  • Made pee-pee in the woods! 
  • Happy Spring!

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.

Dear EarthTalk: I read that a single child born in the U.S. has a greater effect on the environment than a dozen children born in a developing country? Can you explain why?

Hawks Aloft

Once again, it's broad-winged hawk migration time. Whirpools of hawks soon will fill the sky, riding high on thermal lift as sun warms earth. When lift plays out they stream south in an orderly, and countable, procession.

New Hampshire Audubon does just that - count the hawks - at Carter Hill Orchard in Concord and atop Pack Monadnock at Miller State Park in Peterborough.

Here's what Henry Walters, the official counter at Pack Monadnock, wrote two years ago on September 18:

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.

Hover Flies

Hope Abrams, via Flickr Creative Commons

While hiking on Mount Monadnock this summer, I witnessed an odd phenomenon: nearly-motionless hovering insects with orange-yellow stripes over a dark body suggesting wasps or bees. The tight aerial formation of insects hovered at eye level in a shaft of sunlight over the trail.

The “Hover Flies” - sometimes called “Flower Flies” - belong to a LARGE group in the Order “Diptera” (the true flies). Those in the Family “Syrphidae” have only one pair of wings. All wasps and bees have two pairs of wings.

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.

Garbology: Our Dirty Love Affair with Trash (REBROADCAST)

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.

What Can We Do to Reduce Our Light Footprint?

The federally funded National Optical Astronomy Observatory reports that poorly-aimed, unshielded outdoor lights waste 17.4 billion kilowatt-hours of electricity in the U.S. each year.
