Air pollution and why is it harmful
Air pollution refers to the pollution created in the atmosphere by humans for their physical or monetary needs. Any substance that alters the natural properties of the atmosphere, whether it be chemical, physical, or biological, is considered an air pollutant. Air pollution can occur indoors or outdoors. We often forget that the world we live in is not just meant for us but every other organism living here. Air pollution modifies the environment in such a way that it changes the natural charecteristics of the atmosphere. Air pollution is mainly causes due to selfish human need, we need to stop this and make the atmospheres better and a safer place to breath in. The locality that I stay near is called Bannerghatta and is situated in Bangalore. The air pollution here has gotten a bit out of hand due to many underlying factors prompting the students to fall sick in return very often.
People affected by this sir pollution:-
Since the area that I stay in has a lot of colleges nearby, it is mainly a student area with Pgs, hostels and student accommodation flats all around. Youth is considered to be the future of our country, but with such bad atmosphere conditions it is clearly visible that the air that we breath here is not completely safe and can deplete one’s health. Many of my friends have also faced breathing problems and dust allergy whilst walking the streets of Bannerghatta. People also tend to fall sick more often. The air quality Index of Bannerghatta is also considered to be AQI95 pure



Why is the pollution happening:-
There is not one main cause of this pollution in our area but this has been building for ages and if we do not take any strict action right away, this is only going to increase in the upcoming years. But if we start pointing out the on going factors which has resulted in such a decrease in the quality of the air we are breathing in our locality there are plenty right now and these factors are mainly caused by humans for their own needs and in the process to modernize a city, an environment is getting destroyed. The locals around who have been living for so many years have said that earlier Bannerghatta was a beautiful place with long roads and a lake. Due to the increased pollution, the Hulimavu lake in Bannerghatta has also dried up. This air pollution is mainly happening due to underlying reasons like the huge traffic and so many on road vehicles. The huge traffic releases more gas from the exhaust and hence it gets spread into the atmosphere around us. The traffic has increased so much nowadays that people do not get any space to walk and the exhaust coming out of the car makes the atmosphere even hotter . One more main reason is the construction of the metro that is being going on for around 7 years according to a local. This metro construction has broken up so many roads with various construction activities like land clearing, operation of diesel engines, demolition, burning, and working with toxic materials contribute to air pollution. The people working in these constructions have to go through harsh body and weather conditions among so many machines working between them takes a negative turn on their health causing many diseases. Apart from the metro construction there are also many new construction sites that are being built in this area because more students are coming here to live as this place is getting completely urbanized. According to the locals, Bannerghatta and Hulimavu especially before was no that much urbanized and were mainly considered to be the outskirts of the city. But now due to the arrival of new students and setting up of new colleges, more and more students are accomodating near Hulimavu to stay and complete their education or work for a job, because of that new buildings and constructions are being done in that area.
Conclusion
We can conclude that Hulimavu has serious air polution conditions and it is upto us, the youth to take a control over it over the upcoming years by encouraging people to do and follow certain activities to play their parts and not be a problem like cycling and not using cars, the usage of public transport and many other factors which causes pollution in the air.
