Worldwide there are more than 430 reactors currently in operation, unfortunately the Kyoto treaty classifies nuclear as emission free. They may be emission free, but what happens to the toxic waste they have created. With high level radioactive waste the half life may be longer than 100,000 years. Do you really think that the build up of this waste won't become a problem in the future? Eventually we will run out of room to store these deadly chemicals, and surely some of the containers will fail within 100,000 years, no matter what we're told by nuclear supporters.
  What makes nuclear power such a bad idea, is not just the waste it produces, as environmentally deadly as it is, but the fact that these toxic power plants are absolutely unnecessary. Governments may say otherwise, but if they would invest as much money in windmill farms, hydro power and solar energy fields, they would be able to replace all the power that these poisonous plants could ever supply.
   The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel and without proper regard for safety. The resulting steam explosion and fire released at least five percent of the radioactive reactor core into the atmosphere and downwind. 28 people died within four months from radiation or thermal burns, 19 have subsequently died, and there have been around nine deaths from thyroid cancer apparently due to the accident: total 56 fatalities as of 2004. This information is taken directly from the Uranium Information Centre. Now who says that this can't happen again, and what if it's an even larger disaster next time? Can the governments of the world promise us an absolute guarantee that this can never happen again under any circumstances. No, of course they can't, anything can happen in our uncertain future. How then can it possibly be worth the risk? It isn't, so don't believe the hype, and don't back nuclear power for any reason, no matter what they tell you.
  Are we unclear about nuclear energy? No way, we know it's a ticking time bomb that has to be avoided at all costs. Nuclear power plants are just an easy way out, and the easy way out always has it's consequences. There are better ways, and we have to convince our easy fix, short term solution governments that it's just not worth our lives when there are many other, better alternatives out there.
