Preventing species extinction?

It is very difficult to fight against unnatural factors causing the extinction of animal species, hunting or prevent the devastation of forests and wilderness areas is difficult but not impossible, for any cause whatsoever due to acts of man can be controlled .
The problem can not be solved is when an endangered species is suffering from the consequences of natural disasters or predation, so there are many organizations that are in charge of rescuing the last specimens of endangered animals and keep them in captivity, in habitats to preserve their species.
But there are cases where these endangered animals are very difficult to get them used to live in captivity despite having all the ideal conditions for breeding and this comes to complicate this task.
But despite all these problems, environmentalists do not lower their arms and each year they invent new techniques and strategies to ensure that endangered animals can interact with each other and achieve captive breeding.
Our contribution is to work split not continue destroying ecosystems, the main cause of extinction of animals.
