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. in this ppt, i cover source of land pollution, factor for causing land pollution and how to prevent land pollution

3.  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.

5.  Agricultural sources
 Ashes
 Mining sources
 Industrial sources
 Sewage Treatment
 Garbage or waste
 Construction sources
 Deforestation
 Chemical And Nuclear Plants
 Oil Refineries

6.  Include a lot of human actions, like
deforestation, overuse of pesticides
and chemical fertilizers,
desertification, mining, inefficient
and / or inadequate waste
treatment, landfill, litter, etc.
 Many of these are unavoidable;
however, definitely the severity of
these actions in terms of the effects
they have on the land can be
reduced by taking appropriate and
adequate corrective measures.

7.  Mainly refers to cutting trees to
clear land for agriculture, as
well as processes like
desertification and land
conversion.
• Desertification is when effects of
human development or other
actions convert a piece of fertile
land into desert-land or dry-land.
• Land once converted to desert-
land can never be reclaimed by any
amount of corrective measures.

8.  Inefficient use of land as such is not going to cause land pollution.
 However, inefficient use of land amounts to wastage, and hence
shortage of land; and it is precisely during such conditions that
man has to resort to measure such as deforestation and others to
meet his needs.

9.  … key causes of 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.

10.  When the top-most 'soil' layer of land is destroyed or
polluted.
 Soil pollution is again another cause of land pollution that
affects not only the land, but also a lot of other things such
as forest cover of a region, productivity of land in terms of
agriculture, grazing etc. .
 Soil pollution is also caused by wrong agricultural practices,
such as overuse of chemical fertilizers and pesticides.

12.  Land pollutions leads to loss in the forest cover of Earth.This is
in turn going to 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.

13.  Habitat fragmentation is the
fragmentation of the natural habitat of an
organism; cause primarily by urban
sprawl.
 Habitat destruction, on the other hand, is
when land clearing adversely affects
animals special such that their natural
habitat is lost.

14.  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.

16.  Waste materials that are disposed of should have minimal
toxic materials.
 Once the waste is treated, it can be disposed of using
responsible methods.
 Harmful chemicals can also be replaced with less toxic,
biodegradable materials.

17.  As explained by the Stanford Recycling Center, each
American throws away 7 1/2 lbs. of garbage.
 Garbage requires land fills, which takes up large amounts of .
land.

18.  Buy organics products, especially organic cleaners, pesticides,
insecticides and fertilizers.
 The advantage of using organic products is that they are
biodegradable and friendly to the environment.

19.  People should buy
biodegradable products.
Go organic - that's the
mantra for avoiding land
pollution.
 Organic farming,
lessening the use of
pesticides, buying organic
fruits and vegetables and
other products, will keep
land pollution in check.

20.  Initiative should be
taken to grow more
trees.
 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.

21.  Excessive littering is one of most common reasons for land
pollution
 Oil and petrol should be used judiciously.
 So should all the other products and resources made from
glass, plastic, metal and paper.

22.  Organic wastes must be disposed of in areas that are far from
human or animal habitation.
 Find land far away from natural environments to dump wastes
that cannot be disposed of and are essential to industrial
processes.

23. Soil in forested lands are far more fertile than soil
without trees, suggesting that trees have the
ability to fertilize land.

25.  The Central and State Governments
have initiated several programmes
and schemes to check the land
degradation.
 These include centrally sponsored
the Integrated Wastelands
Development Programme (IWDP),
the Draught Prone Area Programme
(DPAP), Employment Assurance Scheme (EAS) and
National Watershed Development Project For Rainfed Areas
(NWDPRA).

26.  As per the requirements of MoEF(Ministry of environment
and forests) has carried out compensatory mangrove
plantation on a 40-hectare area, which is identified as
suitable coastal area for such plantations by BNHS(Bombay
Natural History Society).
 In addition, rehabilitation of degraded lands is also covered
under the state sector Integrated Wasteland Development
Programme (IWDP) and EAS.
