Land pollution is the deterioration or destruction of the earth's crust, often intentionally or unintentionally, due to human activities and abuse of resources terrestrial. This can happen when waste is not disposed of properly or when humans use pesticides, insecticides and fertilizers during agricultural processes. Increasing agricultural land can cause many environmental problems even without pesticides. Agricultural land continued to expand as demand for food increased. The continued growth of agricultural land has led to the loss of habitats for many species. Another problem is the continuous cultivation of a single crop or monoculture, as it depletes the soil of essential nutrients used for native plants and can spread disease throughout the soil. Nutrients can take many years to fully regenerate after a farmer sells his land. The exfoliation of minerals and oil also contributed to the destruction of the earth's surface. Since the 1700s, natural habitats have been destroyed and environments polluted due to industrial practices. This has caused illness in humans and many other animal species. Such human actions have also caused land degradation, that is, many large areas of land begin to lose, or even completely lose, their ability to support life forms and living organisms.
