So the issue we face in the next millennium is not whether there will be a greenhouse effect, but whether humans, by burning fossil fuels, are adding enough carbon dioxide to the atmosphere to change it (and our climate) in significant ways...
...shroud is starting to come off that mystery, thanks to a discovery reported last week in the journal Science. Digging in Madagascar, an international team headed by John Flynn of Chicago's Field Museum has unearthed the fossil jaws of two dinosaurs that appear to be around 230 million years old. "These are either the earliest or among the earliest dinosaurs known," comments University of Pennsylvania paleontologist Neil Shubin. The scientists also found fossils of eight other primitive animals, some of which are a key to the evolution of mammals, which arose at about the same time as the dinosaurs...
Leyh said the amount of fossil fuel and water that go into the production of one hamburger could run a small car for 20 miles and supply water for 17 showers. And according to PETA, slaughterhouses and processing plants pollute water with millions of gallons of animal waste each year...

But some advocacy groups say those targets shouldn't be accepted as goals because the ultimate goal should be an end to fossil-fuel...
Born to famed paleoanthropologists Louis and Mary, Leakey spent much of his childhood on his parents' fossil-hunting expeditions, developing a love of the outdoors and a marked independent streak. After leaving school at 16, he at first rejected anything to do with fossils and archaeology for fear of being trapped in his parents' shadow. But by the time Leakey was in his late 20s, his team was making important finds. He wrote books on the origin of mankind and headed the National Museums of Kenya before turning to wildlife conservation...
