Many sensitive organisms will die from radiation

I was thinking today about how much this nuclear problem is going to affect life on earth here in the future. Because there is at least 7% plutonium in the Mox fuel mix at reactor number 3 and because plutonium is 2 million times more toxic to life than any other reactor's radioactive fuels and since Plutonium has a half life of hundreds of thousands of years, you can bet many sensitive organisms around the world are going to go extinct from it's presence in the environment in Japan, the air, the ocean and around the world. And this could greatly alter how life generally functions upon earth. In some ways I'm less concerned about Japan in this respect because there was already Hiroshima and Nagasaki which already altered all life forms in Japan. So already from those two blasts there are probably already extreme adaptations of all organisms on Japan and around Japan including human genetics. So, this drastic genetic change likely has already occurred in all organisms in Japan. However, I don't know if plutonium was a part of the first A-Bombs or not.

I found the following quote from Wikipedia under the heading "plutonium":
The most important isotope of plutonium is plutonium-239, with a half-life of 24,100 years. Plutonium-239 is the isotope most useful for nuclear weapons.end quote

So, the likely plutonium that is 7% of reactor number 3's fuel is plutonium-239 with a half life of 24,100 years. So, that means the radiation will be here full force for almost 25,000 years now and this will greatly affect the genetics of all life on earth and likely cause many extinctions of more sensitive organisms worldwide.

Humans that get cancer and die from it over the next thousands of years likely will not be able to trace that that is what killed them either since only one particle in a human body will kill that body if it stays for 20 or more years inside that human body in the lungs or tissue.
