Who wants to share your short passage about the pollution around you?Ss: Id like. Our earth used to be a beautiful place. Thick trees and green grass covered the hills and it was the best home for birds and animals. What a beautiful scene it was! However, as time went on, people destroyed the forest to grow crops. What were worse, people let their cattle eat up the grass. So you can see a stretch of wasteland instead of green hills now. As a result, when it rains, the soil is washed down the hills, strong winds blow away the rich soil that lies on the top of the fields.
