Landpollution

  1. 1. POLLUTION • Pollution is an undesirable change in the physical, chemical, or biological characteristics of our air, land, and water that may or will harmfully affect human life or that of desirable species, our industrial processes, living condition, and cultural assets. • Different types of pollution are- Air pollution, water pollution ,land pollution ,noise pollution etc.
  2. 2. WHAT IS LAND POLLUTION ? • Land pollution may be understood as the deterioration of the earth’s land surfaces, often directly or indirectly as a result of man’s activities.
  3. 3. According to CPCB, waste profile of some Indian metro cities is as follows: Cities Waste generated (tonnes per day) Delhi 5,922 Greater Mumbai 5,320 Chennai 3,036 Kolkata 2,653 Hyderabad 2,187 Bangalore 1,669 Ahmedabad 1,302
  4. 4. CAUSES OF LAND POLLUTION DEGENERATIVE ACTIONS • It include a lot of human actions, like deforestation, overuse of pesticides and chemical fertilizers, desertification, mining, inefficient and / or inadequate waste treatment, landfill, litter, et c.
  5. 5. MISUSE OF LAND • Mainly refers to cutting trees to clear land for agriculture, as well as processes like desertification and land conversion. This process may lead to soil erosion and disasters like landslides and floods.
  6. 6. LAND CONVERSION • When a piece of land is converted from its indigenous form to a form used for either agriculture or infrastructure. This is done as a part of rapid economic development and urbanisation.
  7. 7. SOME OTHER CAUSES ARE:- • Other major factors responsible for land pollution include - urbanization, improper waste disposal, industrial activities, nuclear research, chemicals released by all sorts of heavy industries, coal- fired power plants, metals production industries, etc.
  8. 8. EFFECTS OF LAND POLLUTION EFFECTS ON CLIMATE • Land pollutions results in loss of the forest cover of Earth. This is in turn affect the amount of rain. Less rain mean lesser vegetation. The effect of all different kinds of pollution will eventually lead to problems like acid rains, greenhouse effect, global warming.
  9. 9. EXTINCTION OF SPECIES • Species are under endangerment and extinction because of two processes:- • Habitat Degradation-This results due to human population and human activity. • Habitat Fragmentation-It is the process where a large continuous area of habitat is both reduced in area and divided into two or more fragments.
  10. 10. BIO MAGNIFICATION • Process in which certain non-biodegradable substances go on accumulating in the food-chain. The most common example is of methyl mercury in fish and mercury in eagles. Not only does bio magnification put the particular species at risk, it puts all the species above and below it at risk, and ultimately affects the food pyramid.
  11. 11. MEASURES FOR REDUCING LAND POLLUTION DISPOSAL OF WASTES • The simplest method for disposal of waste is crude tipping or open dumping. More satisfactory is controlled tipping or the sanitary landfills. When disposing of waste, the authorities should treat it with various kinds of chemicals, so that it has a very low level of toxicity.
  12. 12. RECYCLING AND REUSE • People should buy and use products that have been recycled. For instance, plastic bags should be given up; instead, jute bags should be used. Reusing old items is another good way to reduce the stress on various resources. Clothes, paper, glass, everything should be recycled and reused.
  13. 13. BIODEGRADABLE PRODUCTS • People should buy biodegradable products. • Organic farming, reducing the use of pesticides, buying organic fruits and vegetables and other products, will keep land pollution in check.
  14. 14. GROW MORE TREES • More trees should be planted. Researches show that trees can actually fertilize the soil. This means that by growing trees, soil will become fertile, agriculture will get boosted and land pollution will greatly reduce.
