首先我们必须面对粮食短缺耕地面积减少的问题，消费需要的增长，倒置了生态失衡：为了养活增加的人口，必须扩大用于生产粮食的耕地和牧场。
世界耕地在19世纪仅有4.5亿公顷，气候随着人口的急剧增加，耕地面积也在迅速扩大，现在已达15亿公顷左右，另外牧场面积约有30亿公顷，这样耕地和牧场面积总和相当与陆地面积的1/3，耕地和牧场的迅速增加严重破坏了森林。
人类为了自身的生存，垄断性地使用着地球1/3的陆地，这对其它生物来说也无疑是一个致命的打击，导致物种灭绝的加速
翻译的好绝对加分！！！！！！！
Firstly we have to face up to the problems, of food shortage and the reduction in arable areas, the growth of needs consumption,which have placed the ecological balance upside down: for the reason of making provision for the growing population, we have to expand arable and grazing lands which are used to produce food.
The world's arable land was only 450 million hectares in the 19 century, the weather follows the sharp increase in population,the areas under cultivation
also expanded rapidly, and it reaches the current size of about 1.5 billion
hectares, separately there are about 3 billion hectares of grazing lands,so the total area of arable and grazing lands is equal to 1/3 of the globe's land areas, arable and grazing lands have rapidly increased its serious destruction to the forests.
For the sake of their own existence, human beings are monopolizing the use of 1/3 of the globe's land areas, this is undoubtedly a deadly blow to other living
