Science Left Behind, by Alex Berezow and Hank Campbell, is a book that exposes the truth that leftists are more anti-science than conservatives. As the book points out, leftists believe in the wholesomeness of all things natural, the unhealthiness of the unnatural, and are averse to clean energy programs, fundamental biological research, genetically modified organisms, product testing on animals, and even life-saving vaccines. Leftists also believe that people are better starving than eating anything other than organic food. The result is that the safety and happiness of millions is needlessly compromised.
