... earth’s temperature as a whole. The earth’s weather and climate is controlled by energy from the sun, which warms the surface of the earth as it, in turn, deflects the energy back into space. Some of this deflected energy is retained within the atmosphere of the earth by greenhouse gases which preve ...

Eutrophication
Eutrophication (Greek: eutrophia—healthy, adequate nutrition, development; German: Eutrophie) or more precisely hypertrophication, is the ecosystem's response to the addition of artificial or natural substances, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system. One example is the ""bloom"" or great increase of phytoplankton in a water body as a response to increased levels of nutrients. Negative environmental effects include hypoxia, the depletion of oxygen in the water, which may cause death to aquatic animals.
