the application of fertilizers, pesticides and insecticides for higher crop yield which pollute land. iii. Deforestation : Humans depend on trees for many things including life. Trees absorb carbon dioxide from the air and release Oxygen, which is needed for life.
Forest helps replenish - - Environmental Economics soils and help retain nutrients being washed away. Deforestation has led to land pollution. Causes of Land Pollution i. Deforestation and soil erosion : Deforestation carried out to create dry lands is one of the major concerns.
Land that is once converted into a dry or barren land, can never be made fertile again, whatever the magnitude of measures to convert it. ii. Agricultural activities : With growing human and pet animal population, demand for food has increased considerably. Farmers often use highly toxic fertilizers and pesticides to get rid off insects, fungi and bacteria from their crops.

Landfills : Each household produces tones of garbage each year due to changing economic lifestyle of the people. Garbage like plastic, paper, cloth, wood and hospital waste get accumulated. Items that cannot be recycled become a part of the landfills that cause land pollution. v.
Industrialization : Due to increasing consumerism more industries were developed which led to deforestation. Research and development paved the way for modern fertilizers and chemicals that were highly toxic and led to soil contamination. vi. Construction activities : Due to urbanization, large amount of construction activities are taking place.
This has resulted in large waste articles like wood, metal, bricks, plastic. These are dumped at the outskirts of urban areas that lead to land pollution. vii. Nuclear waste : The leftover radioactive materials, harmful and toxic chemicals affect human health.
They are dumped beneath the earth to avoid any casualty. Effects of Land Pollution . Soil pollution : Soil pollution is another form of land pollution,
