Extinction is increasing
The extinction’s species is a natural and fundamental process of the evolution. When a specie disappears it’s because another replaces it and is more adapted to the environment.
During the Earth’s history, a massive extinctions of many species have already occurred at certain times for different reasons. However, nowadays the species are extinguished more than a thousand times as on the prehistory.
The main cause of the extinction of the animals generally are the human action.
As always natural resources have been exploited without considering the dangers it can cause.
When a specie is extinguished for the human action, then there’s no other specie prepared to substitute it or prepared to survive.
The main reasons for its extinction
1. The killing of animals for the value their skins.
2. .Fishing and intensive hunting.
3. The contamination of species foreign to its habitat, for "invasive species".
4. The seas’ pollution by the boats petroleum loss.
5. Natural accidents (ex: fire, droughts, floods, volcanoes, glaciers, hurricanes)
6. Other contaminants (deposits of uranium, polonium, radio and other radioactive elements).
7. And the most important : the animal’s habitat destruction
All of these actions are alarming because approximately 21% of known mammals, 30% of known amphibians, 12% of known birds, and 28% of reptiles, 37 percent of freshwater fishes, 70% of plants and 35 percent of invertebrates are cataloged to disappear.
