Indeed, the earth is our home and we have the duty to take care of it for ourselves and for our descendants. In my opinion, we should work out concrete solutions to the problem of pollution from poisonous gas given off by automobiles. For example, the automobiles should be equipped with a device which can dispose of waste gas so as to prevent it from polluting air. Only in this way can we really solve the problem of air pollution caused by automobiles.有关大气污染的英语作文：earth is our home
