Abstract
The history of mankind extends over more than a million years, but its two most important innovations are of a rather recent date: the neoli thic introduction of agriculture 5 to 10 000 years ago and the ongoing industrial-scientific revolution which has led to the present high-te chnology civilizations. Both these events caused a rise in the rate of population increase, and the latter has been intensified by the growi ng use of external energy, particularly fossil fuels. High energy cost s make the expansion of mechanized agriculture a dubious way to solve the global food crisis. Death rates, especially infant mortality, have successfully been reduced by means of efficient health care, but an u nchecked population increase will probably make the WHO goal of "healt h for all by the year 2000" unattainable. The dilemma can be solved on ly by a reduction in birth rates through family planning. How urgent t he control of population growth has become is indicated by the fact th at the human population-one among many millions of consumer species-al ready requires nearly 10% of the global net production of biomass for its own use.
