ABSTRACT
This investigation must by general mission know the main causes, of which the species are in favours in extinction danger, besides to create conscience in the population about this great problem as it is it the extinction of species in our planet, since it causes a great imbalance in the ecosystem.
The species that are in extinction danger need that all we help to do something to conserve our environment, since in all we are and if we do something that harms it, also would harm to us.
The ecology is the science that is in charge to study the relations of the species with environment
Demo ecology is in charge of the study of the populations of the species taking care of some aspects like the growth of the population, mortality and the nasality thus like the factors that they influence in the development of the flora and fauna.
This investigation consists of an exposition of the problem, of a justification, the objectives to follow, referential frame, theoretical frame, hypothesis, a survey and a conclusion of the subject.
The exposition of the problem is where the main causes of the extinction are exposed. Besides to explain so that it is important to do something by the species in extinction danger.
The justification consists of the importance of the subject thus was done and the reasons for the investigation are exposed.
The objectives show the goals to follow to obtain a good investigation of this subject.
Within the framework theoretical are theories of this subject in all history as well as it consists of a referential frame where the historical context is.
In order to conclude, this investigation was made all the population and to make conscience, because we must fight this great problem of the animal extinction.
