One must deal with the competing necessities of biosphere and mankind with all their environmental and climatic consequences. On the other level, it is necessary to resolve the demands of competing nations and worlds within mankind's hierarchy of socioeconomic developmental levels and the "Christmas tree" of sociopolitical, ideological, and military consequences.
