Environmental pollution due to human activities

It can be defined as the unlike changes in chemical biological and physical characteristics of the water land and air because of overpopulation increase in industries and some other man activities such as deforestation and agriculture earth will be overloaded by harmful pollutants which are releasing on daily basis.

Pollutants are of two classes

  1. Pollutants which are biodegradable: these type of pollutant can easily be broken by the action of microorganism and can enter into the biogeochemical cycles .these pollutants can be home wastage products urination sewerage residues of agriculture wood cloth etc
  2. Non-biodegradable: they are stronger than biodegradable and stronger bondage of chemicals. They cannot be broken down into simpler products that are harmless.

Causes of environmental pollution

  • Growth of population:

 Many scientists believe that human is the main cause of pollution in the environment. This observation is applied in all types of the pollution population have many environmental problems which are increasing day by day. Population increase can because the exploitation of resources of nature .it will cause movement of people from the areas of fewer resources to the areas of where enough resources available

  • Deforestation:

 FORESTS are very precious property of a nation because they give us shelter and material for many industries for example timber for building, habitat fertile, and soil that is rich with nutrients and with a high amount of organic compound. The forests are the sources of high rainfall.

It is observed in forest areas rainfall is more than the normal .this is due to the usage of carbon dioxide by plants .plants give us the fuel for different purposes .they give us shelter, in short, we can say that forests the lifeline of national forests can be the main source of food for different animals and plants.

  • Industrial developments:

 The developments of industrial are the main boosters of for the economic development of our society. It is the main source of our socio-economic structure but it has also created many problems for our society. The noise through industrialization gives us a glittering effect and has a negative impact on our minds.

But now it has become the main parameter of economic development of our society installation of new industries have also caused many problems .we should install new industries to boost our economy. More industries can cause the decrease in the forest due to the cutting of trees  digging of soil for the purpose of mining  reduction of crop fields

  • Urbanization:

The movement of people from rural to urban areas has been increased in the last decade due to the industrialization and development of urban areas. This can cause depletion of resources and several types of environmental pollution. Urbanization has now been at the peak in the developed countries. Due to the overpopulation, the job facilities may decrease.

  • Coal burnt thermal power plant:

For the generation of electricity, coal is used widely.in our country, about 62% of the total coal is used in the generation of electricity. This process can do the accumulation of ash in the bottom boiler slag and ash fly.

This material can be used in the manufacturing of cement and bricks and is very useful. We can store ash without disturbing our economy ash needs a large area for dispersal e.g. of a superpower plant is a boil on 900 acres normally require 1300 acres for disposal of ash.

Classification of environmental pollution:

Pollution is classified on the basis of polluted components of the environment.

Pollution is of many types which pollute the air. E.g. pollution of land and pollution water pollution due to noise.

1.Air pollution:

Oxygen is abundantly present in our air. in air carbon dioxide and nitrogen is present .their presence is in particular ratio .when any type of imbalance do occur in the air it is can be called as air pollution .air pollution can be caused due to following factors

Natural:

THEY can be natural disasters e.g. fire in the forest naturally storming of the dust and decay of the matters which are organic

Manmade pollution:

 It can be due to the manmade activities which can be cutting of trees migration of people and establishment of new industries. Several activities of humans are causing the pollution in the air and decreasing the quality of air. As we know man is a social animal and due to his social activities, the air is being polluted by co2 co so, etc. Due to air pollution ozone is badly affected. Many gases are destroying the layer of ozone.

Harmful effects due to air pollution:

The respiratory system is being affected due to the pollution of air and is causing asthma cancer and pneumonia etc

Depletion of ozone

It’s causing UV radiations to be reached on the earth and can cause skin diseases. Acid rain is also caused due to the pollution of the air. Acid rain is due to the nitrogen and sulphuric presence of air.

2.Water pollution:

Water is necessary for our life. Shortage of water is occurring due to the increasing population. The availability of water is being polluted and not capable of drinking .water is being polluted by changes in physical and chemical changes .water pollution is caused due to the factory’s power plants and oil wells.

The development of industrial is the main boosters for the economic development of our society. It is the main source of our socio-economic structure but it has also created many problems for our society. The noise through industrialization gives us a glittering effect and has a negative impact on our minds.

But now it has become the main parameter of economic development of our society installation of new industries have also caused many problems .we should install new industries to boost our economy. More industries can cause the decrease in the forest due to the cutting of trees 2] digging of soil for the purpose of mining 3] reduction of crop fields

Urbanization:     

The movement of people from rural to urban areas has been increased in the last decade due to the industrialization and development of urban areas. This can cause depletion of resources and several types of environmental pollution. Urbanization has now been at the peak in the developed countries. Due to the overpopulation, the job facilities may decrease.

Coal burnt thermal power plant:

For the generation of electricity, coal is used widely.in our country, about 62% of the total coal is used in the generation of electricity. This process can do the accumulation of ash in the bottom boiler slag and ash fly.

This material can be used in the manufacturing of cement and bricks and is very useful. We can store ash without disturbing our economy ash needs a large area for dispersal e.g. of a superpower plant is a boil on 900 acres normally require 1300 acres for disposal of ash.

3.Soil pollution:

It is caused due to the deforestation and solid wastes are dumping. soil erosion is increasing due to the cutting of forests. The land for agricultural use is being lost.

The development of industrial is the main boosters for the economic development of our society. It is the main source of our socio-economic structure but it has also created many problems for our society.

The noise through industrialization gives us a glittering effect and has a negative impact on our minds. But now it has become the main parameter of economic development of our society installation of new industries have also caused many problems .we should install new industries to boost our economy.
