The
pie chart illuminates several dominaint resources vividly from which the more
and more counterproductive arable land envoled, while the table beneath it
demostrates the ramefacation of how these apatheoges devastigate three places
in the world during the 1990s.
So
apparent is it that the pie was cagegoried into four sorts, three of which
shared an appoxiamitely siginificant equal proportion. Specifically,
over-grazing, a quite short sighted behavior often wreak havoc on the fertil
land, ranked on the top, representing for 35%, followed by deforestation and
over-cultivation, with 30% and 28% respectively. The rest 7% went to other
causes.
Also
depressed, as we can see from the table, Europe, which was beyond one’s
imagination, went through the most disouraging performance in land degradation,
sharing a ratio of 23%, almost twice as much the porpotion as Oceania (13%) , where
there are a multitude of islands in the South Pacific envolving Australia and
New Zealand. The lowest total degradation in land was achieved by North
America, with only 5%. The total land degraded rate is a combination of such
branches as deforestaion, over-cultivation and over-grazing, within which all
of the propotion is no more than 12%.
