Human beings achieved so many high-tech goals,with the sacrifice of animals and environment,and the consequence is our planet getting more and more injured.Some people believe that there is no way to solve the problem,while others think that it can be saved by adopting positive measures.Personally speaking,I prefer the last one. Some people hold the negative view,they think human activities certainly do harmful effects on the planet and biology,so it's too late to save them.No one can deny that ecological system was imbalance sometimes.For example,some animal species have endangered,such as a kind of tiger and sheep. And there's a more important reason is that some people aren't aware of the significance of the environmental protection,and it need many years to improve sense of duty.As a consequence,ecological environment is becoming more and more worse,which is not leave much time to do some measures to protect them. However,others believe that this situation will be better with some positive measures are adopted in time.Firstly,the government can make laws to restrain the behavior of citizens and punish them who break the laws.Secondly,enterprises can produce products which do good for the environment.Thirdy,parents and teachers can cultivate the sense of environmental protection.So the situation will be improved. In my opinion,only human beings have the awareness of protection,can we make the planet better.
