Causes of the Danger of Extinction

Another of the main causes of many plants and animals from entering endangered are human activities that attack them directly or indirectly.

In the case of the exploitation of animals for their meat or skins, had taken several steps around the world, but on the black market prices are still very high, so poachers continue species to their destruction.
While this is a direct way of attacking species, the machinery and the disturbances such as noise pollution that cause humans and their machines, they attack indirectly complete ecosystems.

A clear example of this are the helicopters in tourism such as waterfalls and rainforests locations, where birds can not tolerate noise and are forced to leave the area.

The Golden Eagle is an example of this, given ben constant disturbances during its nesting have achieved their reproductive capacity has decreased alarmingly.
