We are responsible for our ecosystem!
As human beings we are part of the general ecosystem we are supposably the most intelligent and greatest in number. Therefore responsible for the welfare of our ecosystem. When a species dies out, it extinct. In the last 200 years, humans have become the most serious threat to animals. By destroying their habitat, or by killing the animals. Humans have already killed off over 300 animals species since 1600! Many more are in serious danger. By the year 2050, scientists fear that as many as half the earth’s plant and animal species could be extinct.
