Threatened Species

Threatened species     

Endangered species is a population of living things (species or subspecies integral evolution) who are at risk of extinction due to small amounts, as well as threatened with extinction as a result of changes in natural conditions or predators.

Various countries in the world have laws special protection to habitat or endangered species, prohibiting hunting, restrictions on land development, zoning or nature reserves and wildlife reserves. The number of threatened species is actually more than the number of species listed and protected by law. In nature there are more species become extinct before it was first recorded, or has the potential to become extinct without ever managed to get the man's attention.

The rate of species extinction throughout the past 150 years is very alarming. And extinct species evolved naturally since hundreds of millions of years ago, but in recent extinction rate is much higher than the average rate of extinction on a scale evolution of the planet. The current extinction rate is 10 to 100 times the natural extinction rate. When the rate of extinction continues or continues to increase, the number of species that have become extinct in the next decade could amount to millions. Most people just think only large-sized mammals and birds are threatened with extinction, but in fact the stability of the entire ecosystem becomes disrupted by the extinction of key species in one of the food chain.
