Mankind's problems, which tend to be global in nature and extent, need global solutions. This paper lists and elaborates on a number of these global problems. No solutions are given. The first part of the paper presents background information on the following issues with which the world's governments will be dealing in the next quarter century: (1) the population problem, (2) the food problem, (3) the world economic outlook, (4) the world educational crisis, (5) the problem of environmental pollution, and (6) some political issues. In the second half of the paper the author discusses the future prospects of the United States, the Soviet Union, Japan, China, and Western Europe and comments on how each of these powers will deal with these global problems. The author's conclusion is that the world future will not be resolved by governments unless and until there is an informed and generally aroused world public opinion. He believes that the citizens of the United States must take the lead in thinking through world problems and in promoting responsible discussion of actions. (Author/RM)
