The oceanographic conditions, climate and its effect on soil quality and various human uses to determine figure out land will be unable to provide food for the ever growing human population.

The FAO also estimates that to meet the need of the human population of 2025, total production should increase to clxv million metric tons.



This significant increase can not come from the get wind of wild species without causing serious vituperate to marine ecosystems, lakes and rivers. Consequently, the increase in the production of seafood must of necessity come from a significant increase in the efficiency of crops. The worlds most populous countries like China, India and Indonesia, or those lacking qualified arable land areas, such as Japan, are play mainly to aquaculture for food production (Solar, 2002).


In 1997, for the first time the world production of farmed salmon surpassed the total global catch of wild salmon. In 2000, the salmon produced more than 1.1 million tons or 61% of the total...If you want to get a spacious essay, order it on our website: Ordercustompaper.com
