On the bicentennial of Malthus' legendary essay on the tendency of population to grow more rapidly than the food supply, this book examines the impacts of population growth on 19 global resources and services, including food, fresh water, fisheries, jobs, education, income and health. Despite current hype of a 'birth dearth' in parts of Europe and Japan, the fact remains that human numbers are projected to increase by over 3 billion by 2050. Populations in rapidly growing nations are in danger of outstripping the carrying capacity of their natural support systems and governments in such situations will find it increasingly hard to respond to crises such as AIDS, food and water shortages and mass unemployment. Beyond Malthus examines methods such as the expansion of international family planning, investment in educating young people in the developing world and promotion of a shift towards smaller families which will represent the most humane response to the possible ravages of the population explosion.

H. REMMERT Small populations are very often discussed, but there seems to be no general overview touching all the self-evident but norma,lly simply neglected problems connected with small populations. First, there are many very different types of organisms, and as every biologist should know, the problems of small populations are very different in different types of organisms. 1. In vascular plants the problems are different from the situation in birds and mammals; in marine benthic animals or in parasites such as tapeworms the problems are different again, and in seasonal planktonic animals or insects they are different from those in biotopes under constant conditions. In tapeworms or in vascular plants, an adult organism seems to be comparable to a population of mammals or birds because its offspring can be so diverse and plentiful. 2. There are small populations which explode and break down to a small population again, and then explode and break down again.
