Global Warming: The Great Evolutionary Oppurtunity

So evolutionists say that mutations are one of the best things that can happen to mankind. (Or any other type of life, for that matter) If this is true, why are mutations so feared?

In Chernobyl, after the radioactive leak, there were several mutants that arose from the radiation. Only problem is that after they arose, they fell. All the mutants died out almost immediately. This happens with all mutants. This is interesting, because mutants are supposed to be good things that survive.

Another problem with mutations is that the "good" ones are way too rare in the cells where they matter (reproductive cells) for any type of order or progress to be achieved. If one "good" trait evolves, fine. But that trait is useless unless it is developed along with other traits that profit the species. "Natural selection" is not going to see any profit in the trait.

For example, with the bombardier beetle, you have many chemicals and enzymes that must mix in the right place at the right time in order for the beetle to fire the mix without blowing up himself. If one of the components evolved (and that's a stretch of the mind) without the others, Mr. Beetle is going sky high. As someone once said, "nothing works until everything works"

In the whole hubbub raised about global warming, which itself is unproven and questionable, it is intriguing that the scientists who support it are saying that the deterioration of the magnetic field and other things are going to cause increased rates of mutation. The result, they say, is not wonderful evolutionary progress, but cancer and disease that will kill millions.
