rainwater that does not percolate into the soil‚ and it carries chemicals and waste that are then drained into the Bay through the storm drains (“Stormwater Runoff”). Plant nutrients like fertilizers are one of the chemicals that are carried by runoff. The rainwater dumps out nitrogen and phosphorus from the fertilizers into the water. These contaminants directly harm aquatic life by causing eutrophication. The growth of algae is enhanced

Therefore control of nitrogen stress during the culture and optimization of wet extraction seem to be valuable options. This study also emphasizes the potential of anaerobic digestion of oilcakes as a way to reduce external energy demand and to recycle a part of the mineral fertilizers. 1.

Journalist Cheryl Lyn Dybus‚ a specialist in marine sciences simply defines dead zones as‚ “coastal waters too low in oxygen to sustain life” (Dybus‚ 2005). Stanford University researchers in a 2005 study state that when water drains into waterways from nitrogen enriched fertilizer treated farmland either during heavy rains or flooding‚ entering

techniques to enhance natural biodegradation by indigenous microorganisms‚ seeding of new bacteria and fertilizing the indigenous populations have attracted the most interest. The application of nutrients as nitrogen and phosphorus in the form of fertilizers have shown to be most effective in accelerating the biodegradation process and at the same time to be environmentally safe.

The Scientific Method “The "game of science" begins with the scientist ’s asking questions about a particular phenomenon which he has observed. He wishes to find out how it behaves and why‚ in the sense of determining relationships between it and other phenomena.” (Kariel‚ Herbert G.‚ 1967‚ California Geographer: Using the Scientific Method to Solve Geographic Problems‚ Vol. 8‚ p. 21) The scientific method is the methods used by scientists to answer questions or solve problems.

Even before construction began on the 3 Gorges Dam the Yangtze River was already suffering from extreme pollution but the addition of the dam has increased pollution levels. One reason is the use of commercial fertilizers‚ another is sewage from passenger boats that tour the river and reservoir (Yangtze Pollution Irreversible) and finally and possibly most serious is the increased greenhouse gas emissions from decaying vegetation.
