"Contaminants in our air and water cause X billion dollars of added health care costs and lost productivity to Americans every year. Rising sea levels and extreme weather patterns cause Y billion dollars of damage to real estate and crop yields every year. What is the EPA going to do to control these losses?"
I really want this anti-science conservative to answer the question about what he really cares about: the wallets of people who own lots of things. His side doesn't care about "good science" or objective truth, and they don't care about the public's well being. They care about money above all else and I think that's where the discussion should be focused.
