Drew Day is an environmental toxicologist whose focus is on water resource management. He currently works as a core member of Yihua, an environmental networking platform. The aim of this presentation is to highlight the issue of eutrophication in China.
Eutrophication or more precisely hypertrophication, is the ecosystem response to the addition of artificial or natural substances, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system. Eutrophication is extremely costly to society and recovery from eutrophication has been estimated to take a thousand years. 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 causes a reduction in specific fish and other animals.
