Sažetak A man has become, affecting all fundamental happenings, that take place in biosphere, one of the most important environmental factors. His activity is in most cases without obeying rhythms in nature, uncoordinated with it, destructive for life, ecosystems and biosphere on the whole. The development of technique and technology has put an important question for a man of how to protect nature and himself from negative consequence of technical and technological progress.
Human activity regularly depends on "the essence" of a man, and not only "to do" or "to have". Not a single action would produce a permanent success without ethical awareness and conscience, therefore it is to no purpose to search solutions only out of moral sphere. A man is also responsible for all non–rational beings on the Earth; he has to live and act in accordance with nature and its laws; Does not have the moral right to do all that is to him physically possible, and the profit cannot be the only goal of economy.
It is not only that our and future generations have the right to live, we cannot deny it to them. On these obligations all states have to care, all societies and all legislatures (national and international).
