The population of the earth grows uncontrolled rate, and the number of animals decreased dramatically. Under the threat of becoming extinct 21% of mammals, 30% of amphibians, 12% of birds, 17% of sharks and 27% of the corals. We lose biodiversity at an unprecedented pace in the history. The reasons are the same: environmental degradation, deforestation of the Amazon, the decrease in volumes of fresh water in lakes, as well as the destruction of coral reef ecosystems.
