Interactions of the Major Biogeochemical Cycles

Global Change And Human Impacts

The circulation and interactions of major elements such as carbon, nitrogen, phosphorus, sulphur, oxygen, and hydrogen are critical for the maintenance of the earth's ecosystems. Human activities including agriculture, industry, and urbanization alter element interactions and contribute to major environmental problems ranging from climate change and depletion of the ozone layer to acidification of soils to the destruction of coral reefs.

Interactions of the Major Biogeochemical Cycles is a new scientific assessment of element interactions in the biosphere.
