Are We Crazy?
I don't think younger folks really comprehend the staggering environmental improvements we have made over the last 40 years. Virtually every metric you can think of on air and water pollution has improved, not to mention the return to health of a number of high-profile species like the bald eagle.
So I am sure that had you told me in the early seventies that the main toxic threats that the government would be campaigning to protect us from in 2009 were carbon dioxide and salt, I would have thought you were crazy.
