On instances of some worldwide problems of environmental protection, the authors refer to the fact, that a target of industrial countries is to help to the developing countries. Mainly it means an aim in such sense, that the dangerous failures and faults which happened in the past, should not be repeated as a consequence of temporaneous economical problems in the Third World. In the long run it is a common interest of all and certainly a sufficient motivation of a commonly coordinated effort in this field. It is at most desirable, that all developing projects, from a simple water supply to the integrated developing concepts, for example eco-agriculture projects, correspond with the national interests as well as with the specific requirements of environmental control.
