Biodiversity Change and Human Health : from Ecosystem Services to Spread 0f Disease
Human actions and their effects on the environment are indisputably the major forces driving changes in biodiversity at both global and local levels. Human-driven climate change, habitat destrustion, invasive species introductions, and nitrogen deposition all result in biodiversity losses (Sala et al. 2000). Some of the general impacts of impoverished biodiversity include decreased food production, decreased food production, decreased food security, the loss of resources for indigenous medicine, diminished supplies of raw materials for new pharmaceuticals and biotechnology, and threats to water quality (Grifo and Rosenthal 1997). There is general agreement among the scientific community that maintenance of natural levels of biodiversity is necessary for proper ecosystem functioning and the provision of ecosystem srvices.
