Land Pollution Explanation
Land pollution is a matter of global concern. According to Encyclopedia Britannica, land pollution involves the deposition on land of solid wastes---e.g., used cars, cans, bottles, plastic containers, paper---that cannot be broken down quickly or, in some instances, cannot be broken down at all by the action of organic or inorganic forces.

Causes
-
Human beings are directly responsible for land pollution. One of the major causes is the increase in urbanization that results in deforestation. The land is contaminated by human trash and litter. In addition, the dumping of industrial wastes (toxic materials disposed by industries) also contributes to this problem. The pesticides and fertilizers used by farmers for crop enhancement seep into land thereby polluting it.
Effects
-
The habitats of terrestrial animals are being obliterated because of land pollution. As a result, the ecosystem will lose balance. Many chemical pollutants are not readily degradable. These can affect many forms of life on earth like plants that absorb them through their roots. This can easily enter into the food chain and hence adversely affect human beings.

Other Effects
-
Land pollution might also contaminate the air and the water. Toxic substances from land may seep into water bodies and cause water pollution thereby affecting the aquatic life. These chemicals may also vaporize adding to the air pollution.
Prevention
-
Land pollution can be prevented by reusing and recycling waste, by avoiding pesticide usage and by the use of biodegradable products. Disposal of waste needs to be categorized into glass, metal and paper and other waste which improves chances of recycling and reduces pressure on landfills.
Need for Regulations
-
In order to alleviate the situation generating from land pollution, stricter laws need to be reinforced in developing countries to prevent litter and enforce proper disposal of industrial waste.
