Gợi ý:
Water pollution is defined as the contamination of bodies of water such as lakes, rivers, oceans, and groundwater. 
Water pollution can have two main causes: point source pollutants such as industrial waste, sewage, pesticides, herbicides, and non-point source pollutants such as pollutants from storm water and atmosphere.
Water pollution can lead to negative effects on humans, animals and plants. Humans may die if they drink contaminated water. Animals may get sick due to polluted water. In addition, herbicides in water can kill aquatic plants and cause further damage to the environment.
So, some solutions to the problem of water pollution include: minimizing the use of pesticides, herbicides, fertilizers; using the minimum amount of detergent and/or bleach when you are washing clothes or dishes; avoiding throwing garbage into lakes, rivers and streams; and helping in cleaning litter around water resources.
