In reading some of this I have some problems with it.

It was taliking about problems caused with photoplankton being destroyed by ozone holes. Ozone holes that are located by the poles. If you really think about it very little photoplankton would be able to be exposed there becuse it is either covered by ice (north) or there is in fact a land mass there (south).

Much was made about Edward Teller being behind the letter that Einstein sent to Roosevelt. Leo Slizard was the prime motivator behind that letter. I think anybody familiar with the real story behind making the forst atomic bomb would realize that.
