The Carbon Cycle Is a Bad Thing

"The life cycle on this planet is the sun, water, carbon dioxide and oxygen. You gotta have those four things for life," he said. "No one's saying that CO2 is evil or bad, just that excessive amounts of it are." He added: "If you go back in time, several hundred million years to the dinosaurs, there's so much CO2 that the plants were rising,. but human beings would be able to survive because there's too much CO2"
