提到森林被破坏,就避不开一大串数字,因为数字最能说明问题。虽然小编看着那些数字也比较晕,但有些数字我们有必要知道:0.3%现在世界森林资源存在的主要问题是数量的减少和质量的下降。虽然20世纪90年代人工林面积年均增长300万公顷,但全球天然林仍每年损失1303万公顷。因此,从总体来说,全球森林仍以每年0.3%的速度下降。其主要原因是热带林地区的毁林开荒和过度采伐。另外,酸雨也造成大片森林衰退,使林地失去更新能力。
When it comes to forest destruction, we can not avoid a long list of numbers because the numbers best explain the problem. Although Xiaobian looked those figures are also more dizzy, but some figures we need to know: 0.3% The main problems in the world’s forest resources now is the reduction of the number and quality decline. Although the area of planted forests increased by 3 million hectares annually in the 1990s, the world’s natural forests still lose 13.03 million hectares annually. Therefore, globally, the global forest is still declining at a rate of 0.3% a year. The main reason is the deforestation and over-harvesting in tropical forest areas. In addition, acid rain also caused the decline of large forest, so that the loss of renewal capacity of the forest.
