Everywhere the Heath brothers look, it seems, there is a lesson to be learned. The Nature Conservancy gives tracts of land spiffy names like the Mount Hamilton Wilderness--a better ring than "1,875 square miles of environmentally critical ecosystem"--and donations perk up. Chalk that up to the power of being concrete. The Texas department of transportation casts Dallas Cowboys and Houston Astros in testosterone-soaked ads telling drivers "Don't mess with Texas," and roadside litter drops 29% in a year. Consider it a score for an emotional appeal to identity--a way of getting litterbugs to believe...
...only species harmed by ocean pollution, of course, but they are easier than most to study. They sit at the top of a food chain that may extend less than half a mile from shore. "The sea otter is the canary in the coal mine for the coastal ecosystem," says Monterey's Murray...

That's why scientists are alarmed by a new study in the journal Science. Over the past 26 years, say European researchers, the diversity of species in British and Dutch wild bees--and the wildflowers they favor--has plummeted. That's not to say there are fewer bees (some species are thriving) but there are fewer varieties, and that is not good news. An ecosystem with fewer species...

We should not forget that the death of even a single bird because of environmental factors can be linked to the fate of human beings, since we all depend on the health of our ecosystem. Tadashi Kawabe Fukuoka, Japan Of Illness and Morality time's interview with evangelist Franklin Graham [May 29] astonished me. He seems to believe that diseases such as cancer and leprosy are the result of "a sinful lifestyle." In Jesus' day, no one knew of the existence of bacteria and carcinogens, so many...
