Modern conveniences, 1 like cars, planes and motorcycles, have made our lives more comfortable. But they have also brought us new problems. Air pollution2 is the worst3 of these problems. It affects every living thing in the world.
Because people are the ones making air pollution, we have a responsibility4 to stop it. If we want to make less pollution, we should go to work by bus or share our cars with other people. It is not too late to fight pollution. Everyone must help!
