Document Summary

Monoculture the cultivation of a single crop in a given area. Reduced genetic diversity in crops with the same species of crops. ****eutrophication: excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen. Flooding the land with too much water and it is not essentially pure. Once water evaporates, it leaves salts behind in the soil and hence causes irrigation. In 2006, a lot of the water has disappeared due to irrigation. ****everything is spatially uneven in this whole course. Argument for: increased nutrition, can make a crop drought resistant, some crops are higher protein.
