Where did she say this?
One issue is this
"Bachmann has charged that global warming is a hoax[60] and has been a vocal skeptic of global warming.[61] She has asserted that since carbon dioxide is "a natural byproduct of nature", it is a beneficial gas required by plant life. She stated that because life requires carbon dioxide and it is part of the planet's life cycle, it cannot be harmful. In a statement she made on the House floor on Earth Day, April 22, 2009, Bachmann stated she was against the cap and trade climate legislation, stating: "Carbon dioxide is not a harmful gas, it is a harmless gas. Carbon dioxide is natural; it is not harmful.... We're being told we have to reduce this natural substance to create an arbitrary reduction in something that is naturally occurring in the earth."[62]"
Another is this, she wants to not teach evolution in favor of creationism, she also is caught lying about evolution here.
"Rep. Michele Bachmann is the latest to get pulled to the side of the road, lights flashing in her rear-view mirror. Talking with reporters in New Orleans following last week’s Republican Leadership Conference, she said “I support intelligent design,” referring to the theory that nature gives scientific evidence of purpose and design.
She continued: “What I support is putting all science on the table and then letting students decide. I don’t think it’s a good idea for government to come down on one side of a scientific issue or another, when there is reasonable doubt on both sides.”
this is anti-science, there is no controversy and by definition intelligent design is not science. Asking for it to be taught will slow americas progress and ensure failure.
