Causes and effects of industries on environment

Industrial pollution  

This kind of pollution is directly linked with industries. This type of pollution is producing many problems for the world. WHO judges the pollution of air, they noted that this pollution is causing many problems to the health of humans.

About 2% of cardiac and lung diseases, about 5% of cancers of lungs, and about 1% of all respiratory infections are caused by this pollution. With the increase in the number of industries, humans are going to be more advanced near the 21 century.

Due to the rapid increase in technology, science is becoming more advanced and further manufacturing of things is seen. With the advancement, there is a bad impact to the world which is pollution. In old-time, industries were in few numbers and were very small and the smoke was the main source of pollutant. But with passage of time this issue is growing rapidly.

Causes of industrial pollution

Due to the lack of the planned action

Due to taking poor steps to overcome the pollution, many of the industries are broken all the rules and throw all of their wastes into the oceans and are creating many problems to the aquatic environment.

Unplanned industrial growth

Due to the poor management of the industries, there are many of the industries are present in the same line and are not taking care of pollution which they spread into the water, into the air. So the human health is affected by environmental pollution.

Uses of outdated technologies

A great number of the industries are still dependent upon the old technologies and are manufacturing things by following the old methods. A number of the factories are avoiding high of the expenditures to produce the things and are depend just onto the old methods.

Due to the presence of small scale industries

Numbers of factories are present which are very small and are dependent on the grant of the government for running their process of manufacturing the things. These small industries with poor management are causing the biggest role in producing environmental pollution.

Inefficient waste disposal

Due to the waste material which is thrown into the ocean and other aquatic sources, aquatic life also disturbs, and when this polluted water is drink, then it causes many chronic diseases and the end is death to the living organisms. [1] [2]

Effects of industrial pollution on the environment

Water pollution

Many industries require a large amount of water for their work. Then after usage, this wasted water removes into the oceanic levels and causes pollution into the water.

This polluted water contains a large number of heavy metals such as mercury, lead, chromium, etc. These metals then transfer into the liver of many fishes through gills.

And when this effected fish is eaten by many aquatic organisms and humans, then these heavy metals are transferred into their body and causes many lethal diseases.

This polluted water is then used by farmers for supplying dry land with water using ditches which disturbs the crops from producing a good yield.

This water also reaches into the underground water level and causes many problems for the aquatic and the wildlife organisms by drinking the same polluted water. This water should be recycled for the best usage in different industries.

Soil pollution

This type of pollution is producing many problems to the vegetation and the agriculture process. It causes many chronic diseases to human health.

 The waste material which is thrown into the ocean also affects soil activity. The toxic chemicals destroy the fertility of the soil and produce the affected fruits and vegetables.

Air pollution

The smoke which is released from the factories and the industries when mixing into the air then causes many of the diseases when it is inhaled. It causes many chronic diseases such as heart attacks, lung cancer, and many other respiratory diseases.

When this air is mixed with water drops into the air, then it falls on the earth in the form of acid rain. Acid rain can cause the stone cancer of many historical buildings.

This acid rain is not good for soil activity. And produces many of the toxins into the plants during absorption of water.

Global warming

The biggest problem to the world is global warming and it is due to humans activities.  Because many of the environmental emissions are only the results of humans.

This kind of emissions contains a large amount of CO2, which the main product forming through the burning of fuels, volcanoes eruptions, deforestation, and methane is produced from the conversion of organic matter into inorganic matter by the process of bacteria’s.

The greater amount of released CFCs also is the main cause of global warming.  A larger amount of greenhouse gases and smoke that are realized from the factories into the air are also the main causes of global warming. Global warming may cause the:

  • Increase in the oceanic level
  • Due to the rise in temperature
  • Due to the extinction risk of the animals
  • Due to the increase in natural disasters
  • Due to glaciers melting


  • Due to the increase in the industries, there is also an increase in the pollution of land, air, and water.
  • Due to the import and export of the products, the transport system is creating many problems for the environment by increasing air pollution. And the main source of air pollution is releasing of smoke from chimneys, vehicles, and other automobiles.
  • The dirty and unhealthy conditions in the factories and their surroundings are causing a big source of damages to human health.
  • In factories, a great number of small children are working. So the country has many uneducated people. [3] [4]
