“Carbon dioxide, Mr. Speaker, is a natural byproduct of nature,” Bachmann said. “Carbon dioxide is natural. It occurs in Earth. It is a part of the regular lifecycle of Earth. In fact, life on planet Earth can’t even exist without carbon dioxide. So necessary is it to human life, to animal life, to plant life, to the oceans, to the vegetation that’s on the Earth, to the, to the fowl that flies in the air, we need to have carbon dioxide as a part of the fundamental lifecycle of Earth.
“As a matter of fact, carbon dioxide is portrayed as harmful. But there isn’t even one study that can be produced that shows that carbon dioxide is a harmful gas. There isn’t one such study because carbon dioxide is not a harmful gas. It is a harmless gas.”
