The supporters of the movement are deeply concerned about the decline of the conditions of life on the planet. What Bernard E. Rollin calls aesthetic value may be a sort of value closely related to the intrinsic value discussed within the deep ecology movement. Elsewhere Rollin criticizes those who maintain that natural objects have intrinsic value on the grounds that such people see value as a mystic property. But even people without special mystical talents speak about intrinsic value of a sort that does not need to be buttressed by poetic rhetoric. Work is in progress to move from international environmental cooperation to the creation of a system of international environmental conventions. Conventions comparable in thoroughness to that of Bern are desperately needed to cover the Third World. But there is no moral or other basis for requiring developing countries to adopt the environmental conventions of rich nations.
