I/read the passage and answer the following question:

Water pollution is the contamination of bodies of water such as lakes, rivers, oceans, and groundwater (the water beneath the Earth’s surface). It is one of the most serious types of pollution.
Water pollution can have many different causes. Factories dump industrial waste into lakes and rivers. Sewage from households is another cause. Farms using pesticides to kill insects and herbicides to kill weeds can also lead to water pollution. These factors cause ‘point source’ pollution while pollutants from storm water and the atmosphere result in ‘non-point source’ pollution.
Water pollution can have dramatic effects.

Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Point source pollutants are industrial waste, sewage, pesticides, herbicides. There are a lot of effects that water pollution may cause. Human and animals may die if they drink contaminated water. Plants will be killed by pollutants as well. So what we can do to solve the problem? Goverment should give heavy fines to companies that are found doing this, the most important measure is to raise the sense of responsibility of the community. In addition, we must save water; treatment of waste before being discharged into the environment....
