Damage land in main reason

The bar graph indicates how the three main cause of land damage in four different areas in the world, including Afirca, Asia, Australia and Europe, with units measured in millions hectares. Overall, the damaging of three main cause of land in the Africa and the Asia is significantly higher than that of the other two categories, namely the Australia and Europe. Among them, especially the figure for breeding in the Africa is highest and the data of farming in the Australia account for the lowest. It is evident that, among three main reasons for land lost in the Africa and Asia, the breeding is the largest, destroying 500 and nearly 400 millions hectares respectively, compare to the figure for Australia and Europe are lower, stand at 220 and 120 respectively. In stark contract, the amount of land used for farming is highest in Asia, standing about 450 mh, whereas the figure for Australia is lowest, hitting at 50mh. The number of land for tree-cutting account for the highest in the Asia, reaching a peak at 480 mh, which is slightly higher than that on Africa, is roughly 380 mh. The number of land used for tree-cutting in the Australia is as high as that on Europe.
