Human beings maybe not occupied the largest population on the earth,but must be greatest specimen to the whole world's change.Looking into the reality,human activities do harm to the plants and animal species.As a consequence,different views about the time that we take actions rise. A large number of people think that it is too late to do anything about this problem.For them,2 reasons consulted.Firstly,the economic growth is developing dramatically and its development has huge negative effects on the plants and animals undoubtedly.However we cannot protect them despite of stopping the improvements.Secondly,the circumstance has shaped and we can hardly change it. On the other hand,some people suggest that we have the capability to improve this situation.In fact,technology has the ability to take some measures. All in all,I agree with the latter opinion since a large quantities of lands still exist in a good manner,so it's not that late for us to do something.At first,we can set nature conservation areas to protect the fragile animals and plants.Furthermore,some animals and plants can bleed artificially to prevent hunting the wild ones.Most but not least,scientists can do research on the energy substitution to decrease the destroy of the biosphere.
