How serious is the "greenhouse effect" on global climate and the environment? Very, says Dr. Jessica Tuchman Mathews, a Ph.D. in biochemistry and biophysics. We are now facing the specter of the "greenhouse effect," the prospect of overloading the earth’s atmosphere with gases released when industrial nations burn fossil fuels like coal and oil, and the Third World strips its forests to farm and burn firewood. In this program with Bill Moyers, she contemplates just how much the earth and the heavens can stand. Mathews suggests that advances in technologies and international cooperation are necessary if the world is to save itself from ecological disaster. (30 minutes)
