The role of humankind in ecosystems causes growing concern to biogeographers. Human transformation of the natural ecosystem by agriculture and industrialisation has led to changes in the pattern of plant and animal distribution and to the simplification of organism-environment relationships. As a result, there has been and continues to be an overall decrease in diversity and stability of the biosphere.
Human populations can modify the environment, either in a planned or inadvertent manner. Either way, this can have negative or positive results. Negative effects of human use of the environment include contamination of fresh water resources; land degradation, toxic waste, loss of biodiversity and air pollution. Since resources are limited, if we continue to destroy, pollute or overexploit the physical environment, then we severely threaten our own existence as a species. The emphasis of biogeography on
the role of humans on the biosphere makes it a study of increasing relevance for future well being of our population.
