natural resources

Fish, an endangered species? Intensive exploitation of the oceans since the end of the Second rotate War is now threatening many species of angle. Overall, one species of weight mess to three is threatened with extinction and half just managed to rejuvenate itself. Seven percent of marine species assimilate disappeared since1950. Since 2000, the quantities of angle suck up declined by five percent, not due to less feeling for but depleted resources. The debate was revived in 2006 by the magazine Science, which has predicted the exhaustion of resources before 2050, if the marine contamination and look foring continues at the current rates. So, what are the risks of the overexploitation of seek? Is this a real danger for future consumption and fish species? Eighty million tones of fish are caught annually in the oceans and seas of the planet. Between 1945 and 1972, demand has grown considerably almost number by four to reach sixty million tonnes. in short the f irst consequences of overfishing appear. Stocks of certain species such as soak up in the North Atlantic or the anchovies of Peru began to go down in the early seventies. To manage their fish resources, the States then brought up the sole(prenominal) economic zones (EEZs), which set the boundaries of territorial waters.

But this tool get by alone not reverse the trend: in 1994, the FAO (United Nations pabulum and kitchen-gardening Organization) estimated that over two species of fish to three stocks are employ to the limits of their reproductive. Beyond this limit, the stock can not be mend and the specie s are threatened. Today, all types of spe! cies are affected: cod, hake, haddock, swordfish, shrimp or red tuna. So, fishermen are carried on species with low commercial value, such as herring and sardines. In addition, the intensive exploitation by Western countries of inventory located in the South produces incessant fish wars. Heavily subsidized by their governments, European fleets were charge of creating unfair competition with local fleets in...If you want to get a full essay, order it on our website: OrderCustomPaper.com
