These are only a few of the impacts that a pollutant can have on a population and ecosystem. Another factor to consider is the ... organisms genetic constitution, and that pollutants can alter a population's gene pool (Freeman, 128).

The TreatyΥs signers agreed not to test nuclear weapons in the atmosphere, in outer space, or ... fission bomb in this age of computers and wide spread access to nuclear data, and India nor Pakistan, the two most worrisome nuclear powers is likely to sign any deal at all. The United States, Great Britain, Russia, and France have joined a moratorium on all testing. Only China continues to develop lightweight, multiple warheads that could be deployed on submarine based missiles. Claiming discrimination, India insists it will not accede ...
