Hell, go back to the first earth day and look at the predictions made then and almost every day since then. None have come to pass, but it is funny that the "solution" to all the doom scenarios is to give the government all your money and dictatorial powers. When that happens the air and water will be clean, there will be plenty of good vegan food for all, and the polar bears will not be extinct.
Oh yeah, everyone will own a rainbow farting unicorn too.......
