Conservationists and environmentalists are battling policies of Trump administration, which aims largely to reverse the contributions of Bill Clinton and Barack Obama toenvironmental protection. If Trump succeeds in reversing progress made under those two, he will surpass Ronald Reagan as the worst environmental president of modern times. The damage done in the next few years could be irreversible. Environmental rights are essential human rights, and all nations should adopt One World under One Set of Laws and give international law precedence over domestic law, with direct bearing on the rights and duties of the people. This means complying with the UN Charter, the Paris Climate Agreement and other relevant pacts. For more see the Charter for Permanent Peace and Development. §5.3
