Pollution,now, becomes a world wide problem. Air, rivers even soil may do harm to animals and plants.
There's an example in our daily life:As the increasing number of cars, we can only see cars on the roads. Yes, it may make everyone convenient, but the air may also polluted by this. what was worse, it seems that people have not realized it. The waste water poured by factories, causes deaths of fish. but the managers likely haven't seen this, what they are thinking is all about the profit. If this continues, not only the fish but also the human beings' life would be changed. the life wouldn't be colorful anymore.so I hope government could take measures to prevent the scary scene come to our life.The goverment could do their best to control pollution,clean envirenment, keep the balance of the eco-system.
at last, I hope everyone could make their own contribution to the beautiful home,for everyone could see the smile of our common mother, the earth.
