Destruction of habitat is the most important cause of extinction of both plants and animals species, e.g. dui to habitat loss, 14% of the earth's land surface covered by tropical rainforest is now limited to only 60 loss in the last few years.
The Amazon rainforest (lungs of the planet) are also being cut and destroyed for cultivation of soybean or is converted to grasslands for raising beef cattle. Besides total loss, the degradation of many habitats by pollution also threatens the survival of many species.
