Read the passage and answer the questions. Land pollution is another term for soil contamination ( for example, by factory chemicals or sewage and other wastewater). It means any kind of long-term land damage, destruction, degradation or loss. Air and water pollution disappear, but land pollution doesn’t. It stays exactly where it is. Radiation can contaminate land for thousands of years. That means radioactive waste dumps remain that way indefinitely. The biggest problem comes when contaminated land is returned to use as buildings or agriculture land. People might get their water from rivers, but they don’t know that the contaminated groundwater gives water to the rivers. Diseases might happen over year for this reason. We should try to find a way of stopping or reducing land pollution. We should recycle old things to reduce our need for new ones. Also, we need to clean up many contaminated sites. 1.
