Causes of Land Pollution

Land pollution is the pollution of the Earth's natural land surface by industrial commercial, domestic and agricultural activities. 1. Increase in urbanization :- Construction uses up forestland. This leads to the exploitation and destruction of forests causing imbalance to climate. There is more demand for water, hence reservoirs are built causing the loss of land. 2. Increase in agricultural land :- As the human population grew there was a greater demand for food, thus more land allocated to agriculture. 3. Overuse of pesticides and chemical fertilizers :- Chemical herbicides and pesticides kill bees and other pollinators. Chemical fertilizers do not put minerals into the soil. Consequently, the crops grown have very few minerals and causes non-biodegradable chemicals to enter and accumulate in the food chain. Vegetation alone has the unique ability to convert inorganic minerals absorbed from the soil and water into organic forms that animals and humans can use. Beca
