The human population of the world is increasing by about 1.5% per annum, adding about one hundred million people to the human ark each year. Not all agree that population growth on this scale constitutes a problem, but there is wide acceptance that the world's human population cannot go on growing indefinitely. Where do the limits lie, and how can they be determined? What are the problems caused by population growth and how can we safeguard the future of our planet? In this important book, leading authorities examine the implications of rapid human population growth for global stability and security. Avoiding the hysteria and over-statement that so often characterize discussions of human population issues, the book represents an important assessment of current prospects for the process of sustainable development, based on care for the environment.
