Some of the Causes

-> The chemists used for the conservation from the wood of the granaries;

-> Illegal slaughtering and generalized pursuit

-> Lacking of natural preys and perturbation of the habitat;

-> Perturbation of the places of nidification;

-> Captures for commerce;

-> Species threatened by the intense and indiscriminate hunting;

-> Destruction of foods;

-> The last inquiries point which thousands of animal species were extinguished in the last hundred years. A great deal of these species never will be known by future generations. We know that, a great deal of them, they might reveal to humans important information on the environment and even the cure for determined types of diseases.
