Pro- lower emission of greenhouse gasses. Con- produces a radioactive waste which is difficult to dispose of.

Three part question here...

What is an effect of ozone depletion, how are they formed, where is a current ozone hole located?

Not sure what the "tan effect" of ozone depletion is, but
there's still the ozone hole above Antarctica, I believe.

The location is right, but you need all three answers.

Oh, okay, I understand the question now!
Ozone depletion occurs chiefly with the emission of CFC's and VOC's (chlorinated fluorocarbons and volatile organic compounds). These have excess chlorine atoms (Cl-) that will bond with free oxygen (O^2-) and prevent the formation of ozone (O2 + O = O3) in the stratosphere or at the stratopause. This leads to ozone depletion and ozone holes, which means that there is a gap in the ozone layer and effects include increased rates of cancer and cataracts due to lack of protection from harmful UV.

Alright, here's an easy one: explain why there is so much nitrogen in the atmosphere but most organisms can't use it?

Nitrogen gas is the most abundant gas in the Earth's atmosphere, but most organisms cannot use nitrogen in its diatomic form. Only a few types of bacteria are able of converting nitrogen gas to ammonia, a form that is usable by a lot of organisms. The Haber process can also be used to fix nitrogen so that it can be used by organisms.
