How have people affected soil?
Metal and oil come from rocks. People have dug up the soil to get the metal, gas and oil. Trees have been cut down and the rain washes the topsoil away. Erosion causes lakes and rivers to get polluted. Erosion causes our native plants and fish to die because they can’t live in polluted water.
