Evidence suggests that production of carbon dioxide and methane from human activities has already begun to change the climate and that radical steps must be taken to halt any further change

Human activities are clearly increasing the carbon dioxide content of the earth's atmosphere. The question is: Will enough carbon be stored in forests and the ocean to avert a major change in climate?

Life is maintained by the finite amount of solar energy that is fixed by green plants. An increasing fraction of that energy is being diverted to the direct support of one living species: man

Radioactive elements or pesticides such as DDT that are released in the environment may enter meteorological and biological cycles that distribute them and can concentrate them to dangerous levels

Ecosystems, the basic biological units of man's environment, are altered significantly by ionizing radiation. Forests appear to be among the most sensitive systems; weed fields are more resistant
