When people breathe out air, they give off carbon dioxide, which is needed by plants.
People build buildings, cut down trees, use chemicals that pollute the water and soil, drive cars and use factories that pollute the air, etc.
People can also affect the earth's surface in positive ways, such as planting trees, using agricultural methods that do not harm the earth, driving cars less, etc.
