How to Protect the Earth
The earth is our home. We should protect it. First, reduce water pollution. Stop factories from pouring waste water into rivers and don't throw rubbish into them. Second, cut down air pollution. Walk or ride a bike instead of driving, and plant more trees. Third, handle rubbish well. Throw it into different bins and recycle things like paper and bottles. If we all do these, we can make the earth a better place.
