$\huge \mathfrak{\red{pollution}}$

$\huge\mathfrak {What \: is \: pollution?}$
Pollution is introducing something into the environment that is dirty, unclean or has a harmful effect on the ecosystem.
$\huge\mathfrak{Present \: scenario \: of \: Pollution}$
Pollution is a key issue that has been affecting our earth. Although it is an issue that has been prevalent since ancient times, in the 21st century its harmful effect has been felt on a large scale. 

Although the governments of different countries have taken several major steps to curb these effects, there is still a long way to go.

Several natural processes and cycles get disturbed due to this. Not only that, many flora and fauna today either have gone extinct or are endangered. Due to the rapid increase in the amount of pollution, animals are losing their habitat at a rapid speed.

Pollution has affected several major cities across the globe. A majority of these polluted cities lie in India. Some of the most polluted cities in the world are Delhi, Kanpur, Bamenda, Moscow, Heze, Chernobyl, Beijing among others. 

Although these cities have taken several steps to curb pollution, they still have a long way to go. The air quality of these places is poor and there are cases of land and water pollution as well. Now it's time that the administration of these cities prepares strategies to check these issues.

$\huge\mathfrak{Types \: of \: pollution}$
Basically, there are four types of pollution -

1).Air Pollution:It is mainly caused due to vehicular emission of gases. Harmful gases are produced as a by-product in factories and industries, by burning toxic substances such as plastic and leaves in the open, by the vehicular exhausts, by the CFCs used in the refrigeration industry, etc.

2).Water Pollution:It is another big challenge faced by humans nowadays. Sewage waste, wastes from industries or factories, etc.are being dumped into water bodies such as canals, rivers, and seas directly. This has resulted in a loss of habitat for marine life and dissolved oxygen present in water bodies has started disappearing.

The shortage of potable water is a major repercussion of water pollution. People are forced to drink polluted water due to which they get diseases such as cholera, diarrhea, dysentery, etc.

3).Noise PollutionApart from contributing to air pollution, a large number of vehicles on the Indian roads also contribute to noise pollution. This is alarming for those who live in urban areas or near the highways. It causes stress-related issues such as anxiety in people.

This due to the fact that most Indian cities such as Mumbai, Bangalore, Delhi, Chennai, etc. have an active nightlife.

4).Soil Pollution:A major part of the Indian pradioactive pollution. Handling and mining of radioactive substances, testing, minor accidents occurring in radioactive power plants are other major causes contributing to radioactive pollution.
