用这５个提示写一篇有关机器人的作文

As is shown by the two graphs,between 1800 and 1990,the U.S population grew from about 2 million to 250 million.In contrast,at least 70 wildlife species bid farewell to the country over the same period of time.It is obvious that the extinction of wildlife resulted from the population explosion.
There are some possible reasons for the effect.First,with the rapid growth of human population,inhabitable areas were expanding so fast that few areas were left for wildlife.Second,a great number of wildlife species were killed for food,for money and even for fun.Finally,a host of newly-built factories constantly discharged harmful gases and liquids,which seriously polluted the environment.And this global industrial pollution speeded up wildlife extinction.
In my opinion,it is imperative to take effective measures to save all wildlife species.Firstly,the birth rate all over the world must be put under control.Secondly,we should establish more natural conservations for wildlife,especially for rare animals and those in face of extinction.Last but not least,we should educate the people to realize the importance of wildlife protection.Only by taking firm actions can we prevent wildlife from decreasing continually.
