 LAND POLLUTION


What is land pollution ??? 

  • Land pollution, in other words, is nothing but degradation, damage to the surface of the earth and its soil because of human activities. 
  • The increase in a number of cities and towns due to enhancement in a population are also the reasons for land pollution. 
  • A land gets polluted even due to lack of green cover on land which results in soil erosion.

Causes of Land Pollution:

  • Deforestation and soil erosion
  • Mining activities
  • Agricultural activities
  • Construction activities
  • Industrialization
  • Nuclear waste
  • Sewage treatment

Deforestation and soil erosion

        Deforestation which makes dry land is one of the major reasons of land pollution. In this, we need to observe that once a land becomes dry or barren then it cannot be regained i.e. it will be very difficult to regain its fertility.

Mining activities

        At the time of mining activities and extraction activities, many land spaces are made under the surface.

Agricultural activities

        With the increase in human population there is an increase in demand for food also. Farmers use toxic pesticides and chemicals to get rid of distinct types of insects and these types of practices result in poisoning of soil.

Construction activities

        Because of urbanization these days, construction activities are at a high rate and these activities generates waste particles at a high amount.

Industrialization

        There is an increase in population which results in an increase in food, shelter, and other required things. This requirement gave rise to industries and these industries require raw materials which lead to deforestation and also they produce a large amount of waste which has to be disposed of.

Nuclear waste

        Nuclear waste from a nuclear plant is dumped beneath surface of the earth for avoiding causality.

Sewage treatment

        After the treatment of sewage, huge amount of solid waste goes into landfills which lead to pollution of the environment.

Effects of Land Pollution:

  • Change in climate patterns
  • Pollution of soil
  • Impact of environment
  • Effect on human health
  • Cause air pollution
  • Effect on wild life
  • Distraction of tourist

Solutions for Land Pollution:

  • Reduce the use of fertilizers and pesticides
  • reduce, recycle, and reuse.
  • decrease buying package items.
  • increase buying biodegradable products.
  • properly dispose of garbage.
  • encourage organic gardening.

Air Pollution What Is Air Pollution??                     Air pollution is the introduction of  chemiclas, particular matter, or biological materials that cause harm to discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. Types Of Air Pollution There are several types of air pollution, mainly Indoor Air Pollution and Outdoor Air Pollution. These include smog, acid rain, the green house effect and hole in ozone layer. One type of air pollution is the release of particles into the air. Another type of air pollution is the release of poisonous gases.  Outdoor Air Pollution Smog Smog is a type of large scale out pollution. It is caused by chemical reaction between pollutants derived from different sources. Indoor Air Pollution      It more dangerous than outdoor air pollution because we do everything in enclosed environme...

  GLOBAL WARMING   Introduction Global Warming is the increase in average temperature of the earths near surface air and oceans. Most of the observed temperature increase is caused by increase concentration of greenhouse gases.  Major gases                             water vapour     = 36-70%           carbon dioxide  = 9-26%           methane           = 4-9%           ozone               = 3-7% Causes of global warming Emission of green house gas like carbon dioxide, methane, nitrous oxide etc. The major source is carbon dioxide (80%). 20% by methane and nitrous oxide . Carbon dioxide The major source of carbon dioxide is the power plants. Burning of fossil fuels for the purpose of electricity generat...
