Dioxin: Studied to Death.

He's not the quickest calf in the pasture, so it took U.S. President George W. Bush, and his White House handlers, a few months to grasp a basic rule of modem American electoral politics: Don't look bad on the environment. After thirty-one years of Earth Days, the environment has become a mom-and-apple-pie issue; 68 percent of Americans say they support the goals of the green movement. Thus it was no surprise to see Bush's poll numbers sliding, even among Republicans, as his Administration abandoned lower limits on arsenic in drinking water, the Kyoto Protocols on climate change and a host of other urgent measures. Bush has a problem. The U.S. Environmental Protection Agency is preparing to release a major study of dioxin's health effects that, if uncensored, will surely increase pressure for dioxin's rapid phase-out. Meanwhile, the chemical, paper and other dioxin-related industries are pressing the U.S. Government to block the study's release. If Bush heeds their call, he shields industry from costly new regulations but reinforces his anti-green reputation.
