Public concern over the environmental crisis has begun to stimulate not only action on the local and national level but also proposals for new international efforts, mobilized especially by current preparations for the United Nations Conference on the Human Environment scheduled to be held at Stockholm in June, 1972. 1 Some of these proposals are being presented in the form of draft conventions, such as the Draft Convention on Conservation of the World Heritage, prepared by the International Union for Conservation of Nature and Natural Resources (IUCN), 2 and the Draft Convention for the Regulation of Transportation for Ocean Dumping, prepared by a U.N. inter-governmental working group on marine pollution. 3
