Environmental issues are interdisciplinary in character and raise a variety of legal, social, economic, and ethical questions. Science has an important role in enacting, implementing, and enforcing environmental law. However, those conflicting questions are not easy to be resolved only by science. In the 1960s, Rachel Carson had questioned the government''s manipulation of science to support the toxicological safety of pesticides, which therefore launched the beginning of the environmental movement in U.S. Even today, the continuing debate on regulatory reform has not yet reached consensus on how governmental institutions and procedures should be structured to make decisions better and more broadly acceptable for environmental protection.When science has been playing more important and complicated role in decision-making, what should we do to right the wrongs of the pasts and better environmental protection for our future?
