title: Population growth. Implications and problems.
abstract: Population growth in the twentieth century is at its highest level in history, with the world's population now doubling in approximately 40 years. An unprecedented 90 million people are being added worldwide each year, with most of the growth taking place in the developing world. The implications of this rate of growth are discussed, as are some of the program efforts underway to decrease the rate of increase.
