XII. Suggested aswer
        Land pollution is the destruction of the earth’s land surfaces, often directly or  indirectly as a result of man’s activities and their misuse of land resources. It occurs when waste is not disposed of properly, or can occur when humans throw chemicals unto the soil in the form of pesticides, insecticides and fertilizers during agricultural practices. Exploitation of minerals has also contributed to the destruction of the earth’s surface. Contaminated lands can cause problems in the human health and also cause various kinds of cancers. Moreover, dump sites and landfills also come with serious problems like very bad smell and odour in the town. The greatest prevention to land pollution is in the three ‘R’s’: Reduce waste, Re-use things and Recycle things. (122 words)
