1). What impact did Chernobyl have on the world? 2). Thirty-five years after the Chernobyl disaster, what lessons have we learned?

Explanation:

Mankind seems to learn very little from anything -- good or bad. There are many things you could say about Natural Gas or Oil, but one thing that neither one could do is create another Chernobyl.

People are saying that the cleanest and most efficient way to go would be to use Nuclear Power Plants. I admit that Gas and oil create their own set of environmental problems, but nothing as far reaching as something lasting 35 years as Chernobyl has done

Scientists are bewildered by Chernobyl heating up again. They cannot explain why let alone what can be done. Each of the alternate energy choices have their problems and have their ill effects on the environment.

a. i. only is correct.
