Professor William Happer: 'We're in a CO2 Famine, Not a Crisis—It's Essential for Life

"We're in a CO2 famine now... It's unbelievable that they've managed to turn this beneficial gas, a part of life, into a threat."

– William Happer, Professor Emeritus of Physics at Princeton University.

"They talk about carbon pollution. I can't imagine what they're talking about. We're made of carbon, and we breathe out two pounds of CO2 a day, each of us—that's 8 billion people."

"Many of them say, well, people are the real problem, it's not the CO2, we've got too many people, and really we can't have more than a billion people in the world."
