Wetlands

Wetlands are not just home to different animals and plants, but they also control flooding and help keep the Earth’s water clean. Flood waters move more slowly through wetlands because they have to go through barriers of plants and dirt. Wetlands help stop erosion because the plants stop the soil from washing away. Plants and soil in wetlands slow water enough that bacteria and other decomposer organisms can break down and even absorb some types of pollution. Wetlands are wet. Let’s keep them that way.
