About a quarter of all the species of amphibians and reptiles inhabiting the United States, are threatened with extinction, and therefore the need to expand the Red Book of the United States, according to the U.S. Center for Biological Diversity.
"According to the researchers, one of four species of amphibians and reptiles are threatened with extinction. However, only 58 of them are included in the Red Book of the United States, which protects 1.4 thousand species," — said in a statement.
In this regard, conservationists have made a request by fish and wildlife U.S. futures listed in the Red Book of 53 species of frogs, turtles, salamanders and lizards, which are threatened by disease, habitat loss, climate change, settled outside predators and pollution. In this species, endangered, live in 45 of the 50 states.
"The direction of the report of 450 pages to the authorities was the result of long work of social organization and biological scientists, in order to identify the most vulnerable, but at the same time the most vulnerable species. Despite the fact that they rarely make the news, reptiles are a risk which they have not yet encountered. It is caused by human activity, putting many species at risk of extinction "- note the animal protectors.
The status of these species in the world is not much better. According to the International Union for the Conservation of Nature in 2011, a total of 664 species of reptiles, which makes up 20% of the total, may soon become extinct. Cases in amphibians are worse — the threats to more than 1.9 thousand frogs, toads and salamanders (30% of species). In this case, scientists do not have enough information about the state of nearly a quarter of species extinction is faster than scientists can study them.
