Extinction speed

Since the life on the earth, has ten million kinds of extinct or endangered animal plant, these belong to the normal natural evolution.

But in the past 300 years, due to habitat destruction, environmental pollution, human hunting, and so on reasons, the speed of species extinction improved 1000 times. According to statistics, every 15 minutes to have a kind of extinction. In the next 20 years, 1 million species face extinction.

According to this speed, may be less than 100 years, the only remaining creature is human in the world.

So, species extinction is a big problem, we must figure out a way to slow down the rate of extinction, perfect the law, to protect the endangered creatures.
