Document Summary
Humans are altering the operations of the earth"s atmosphere, biosphere and geosphere which is the environmental crisis. The health and reproductive success of amphibians are damaged by interactions between an increase in uv light (due to thinning of the stratospheric ozone), toxic chemicals, infections caused by virulent fungi and bacteria. This also indicates environmental threats to human health. Driving forces of environmental crisis: population growth and industrialization. Industrialization has outgrown the growth in population: increase in industrial production, use of fossil fuels, manufacturing, and number of automobiles. Human activity doubled the concentration of methane and produced long lived ozone destroying chlorofluorocarbons into the stratosphere. Emissions of sulfur and nitrogen led to acid rain. Recognizes that humans are participants in complex ecosystems and their potential for health is propotional to the health function of the ecosystem. Takes into account health services the natural environment provides such as soil production, pollination, water cleaning, etc.
