Question

What are the disadvantages of pollution and its points?

Answer 1

Hi friend.

As the question doesn't specify a type of pollution ,i will take it as air pollution.

An increase in the content of harmful substances in air is called air pollution.

The various reasons for air pollution and their effects are given below:

• The fossil fuels like coal and petroleum contain small amounts of nitrogen and sulphur. When these fuels are burnt, nitrogen and sulphur too are burnt and this produces different oxides of nitrogen and sulphur. These gases also dissolve in rain to give rise to acid rain.

• The combustion of fossil fuels also increases the amount of suspended particles in air. These suspended particles could be unburnt carbon particles or substances called hydrocarbons.

• Presence of high levels of all these pollutants causes visibility to be lowered, especially in cold weather when water also condenses out of air. This is known as smog and is a visible indication of air pollution. • A regular breathing of air that contains any of these substances increases the incidence of allergies, cancer and heart diseases.

Hope this helps!

Pollution is when something is added to the environment harmful or poisonous to all living things. Polluted water or garbage in the water bodies is a type of pollution.In other words, pollution means a sudden change in the environment due to emission of pollutants such as carbon monoxide etc.

• Air Pollution: It is the contamination of the natural air by mixing it with different pollutants such as harmful fumes and chemicals. This type of contamination can be caused by burning material or by gases emitted by vehicles or harmful fumes emitted as a by-product of industries. Global warming is one of the biggest side effects of air pollution as per the experts.

• Water Pollution: It is the contamination of the water on the planet Earth. It includes water contamination by pollutants such as bacterial, chemical, and particulate that reduces the purity of the water. Oil seepage, as well as littering, is one of the most common forms of pollution. It mainly occurs in lakes, oceans, rivers and even underground reservoirs.  

• Soil Pollution:  It is also known as land pollution. It is the contamination of the soil or the land that prevents the growth of natural life. It includes land usage for irrigation, wildlife as well as habitation. The very common causes of soil pollution include hazardous wastage, mining as well as littering, non-sustainable farming practice, seepage into the soil, etc.
