The author of this web site is a scientist with an postgraduate degree who has published numerous research articles. The material is believed by him to be essentially correct, or at least basically consistent with current scientific literature. However, the information presented here has not been peer reviewed (evaluated by other specialists in the relevant fields). Thus, it should be only considered as the opinions of one individual and not used to make important decisions without review.
In particular, no governmental agency should use this information alone to make policy decisions. In the United States, the National Academy of Science is the appropriate agency to generate reports to serve as a foundation for policy decisions. Other countries have similar agencies (take note Tony Blair).
