Don't want a children's toy containing lead paint manufactured with child labor in your state? Congressman King and the House Agriculture Committee say "tough." Want the workers in your state to have a better chance? Your state won't have the right to choose. The Feds are encroaching.

How is it possible that we have moved from a free system that enhances our environment to a costly system that destroys our environment?

William S. Becker

Executive Director, Presidential Climate Action Project

In picking Gina McCarthy to lead the EPA, Obama sent the Senate a nominee who should satisfy, if not delight, Republicans as well as Democrats. But these days, the Senate rarely stumbles in the right direction. Senate Republicans are playing games with Obama's selection.

With less than 30 animals left in Borneo and an estimated 80 animals in Sumatra, the Sumatran rhino should be a constant reminder to all consumers of the devastating effect industrial palm oil plantations have on wildlife.

Given the myriad ties that bind, it's tough to fathom any other decision being made by the DOE on Freeport or any other LNG export terminal from here on out. And the ecological consequences of that will be disastrous.

Few of us will ever venture past the 60-mile boundary that separates Earth and outer space. If you do, though, you're likely to experience something known as "the overview effect" -- a cognitive shift in how you perceive our planet.

Who has freckles, pigtails, and is still holding out from joining the Fair Food Program? If you guessed the fresh-faced mascot of Wendy's, give yourself a gold star.

Greenpeace is offering to testify about being the target of politically motivated audits in 2004, because regardless of which party holds power, these abuses are egregious and must stop.

The demand for shark fins is what drives almost all shark deaths. Some species may have declined by as much as 97-99 percent in the last 35 years. In other words, as few as one out of 100 may be left of some species.

The truth is that roses -- if you buy the RIGHT roses (old or new) for your location and climate -- are incredibly tough shrubs that can survive almost anything -- even the gardener's ignorance.

100 million sharks are disappearing from our oceans each year, primarily driven by the lucrative trade in shark fins. A bill that would prohibit the sale and consumption of shark fins in Texas, passed the Texas House. However, this bill faces a fight ahead.

Economist, Environmental Defense Fund and author, 'But Will the Planet Notice?'

Up to a point, GDP does tell us important facts about people's lives, livelihoods and aspirations. Living on a dollar a day is miserable no matter how you look at it. Choking on economic growth, of course, is equally bad.

I spoke at length with DeChristopher about hacking the Democratic party, arcane but vulnerable processes like elections and auctions, why Americans really should spend more time in prison, and other tragicomic matters of consequence. Read up, plug in, turn out.
