Systems dependent on industrially fixed nitrogen, as well as those that make up for nutrients lost from the system by bringing in more, have the highest impact. Organic farming and gardening should be based on a system of low environmental impact. The Nat ...

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.
