Genes, pollutants and human diseases

Abstract

The use of traditional Western concepts of disease (i.e. the ‘germ’ theory) has guided the use of scientific knowledge and technologies in the Control of acute infectious diseases (Gori & Peters, 1975; Trosko & Chang, 1978c). The intervention of all sorts of technologies has prolonged the life expectancy, allowing more people to reach the limit of what appears to be a rather fixed life-span (Hayflick, 1976). At the same time, human beings have used technologies to alter out dependence on the natural enviroment We intervene on many levels to minimize threats to our dependence on natural forces for food (e.g. agricultural technology, food additives), for water (e.g. wells or dams), for health (e.g. instituting sanitary measures or using drugs), for protection against the elements (e.g. wearing clothes, building homes with heaters and air conditioners) and for pleasure (e.g. snowmobiles, etc.). It is now extremely clear that much of the ‘effluents of our technological affluence’ can be harmful to living systems.
