While it is against my policy to do people’s homework for them, I do take exception to question #18. Uranium stocks, as well as all the trans-iron elements, are constantly being renewed in supernovae throughout the universe, and all of life depends upon nuclear fusion reactions in those stars, also creating all the sub-iron elements, making nuclear energy part of the overall organic interdependency. Conversely, in normal actual practice, tritium escapes from nuclear plants, the only issue being "how much", and enormous heat escapes as well, both contributing forms of air pollution.
