Essay on Preventing Air Pollution in Metro Cities in 100 Words
Air pollution has become a serious problem in metro cities like Delhi, Mumbai, and Kolkata. The main causes are smoke from vehicles, factory emissions, burning of waste, and dust from construction work. According to the World Health Organization, nine out of ten people in cities breathe air that is not safe. Dirty air can cause breathing problems, asthma, and lung diseases, especially in children and old people. To prevent air pollution, people should use public transport, plant trees, and stop burning garbage. Factories must use filters to reduce smoke, and roads should be cleaned regularly to control dust. Government should promote electric buses, solar energy, and bicycle tracks for clean travel. Students can also help by spreading awareness about clean air in schools and homes. Together, small steps from everyone can make our cities greener, healthier, and pollution-free for the future generations.

Essay on Preventing Air Pollution in Metro Cities in 200 Words
Air pollution is one of the biggest environmental challenges in metro cities. In places like Delhi and Bengaluru, the Air Quality Index (AQI) often reaches “very poor” levels, mainly because of vehicle smoke, factory emissions, dust, and crop burning nearby. Studies show that over 1.6 million deaths in India every year are linked to air pollution. The harmful gases like carbon monoxide, sulfur dioxide, and nitrogen oxides make the air unsafe to breathe.
To prevent air pollution, metro cities need a combination of government policies and citizen action. Using public transport, electric vehicles, and cleaner fuels can reduce smoke from traffic. Industries should install pollution control filters and shift to renewable energy. Construction companies must cover sites and sprinkle water to stop dust. The government should also plant trees along roads, build more parks, and strictly ban burning of waste and leaves.
Schools can play an important role by teaching children how air pollution affects health and climate. Students can join “Clean Air” campaigns and encourage their families to follow eco-friendly habits. Wearing masks and checking AQI before going outdoors can protect us on bad air days. Preventing air pollution is everyone’s duty. When people, schools, and governments work together, our metro cities can become cleaner, greener, and safer places to live.

Essay on Preventing Air Pollution in Metro Cities in 300 Words
Air pollution is one of the most dangerous problems faced by metro cities today. Cities like Delhi, Mumbai, Kolkata, and Chennai have millions of vehicles, big industries, and constant construction work. These activities release smoke, dust, and gases such as carbon dioxide, nitrogen oxides, and sulfur dioxide into the air. The tiny dust particles known as PM2.5 are very harmful because they can enter our lungs and bloodstream. According to the World Air Quality Report 2024, Delhi was again ranked among the most polluted capitals in the world.
Breathing polluted air causes asthma, lung infections, and heart diseases. Children and the elderly suffer the most. It also reduces visibility, damages crops, and contributes to global warming. Air pollution has both health and environmental effects, so preventing it is extremely important.
To reduce air pollution, metro cities must take several strong steps. First, public transport should be improved to reduce the number of private vehicles. Encouraging electric cars, CNG vehicles, and metro trains can cut down harmful emissions. Factories should use eco-friendly machines and smoke filters. Construction sites must be covered, and water should be sprinkled to control dust. Burning of waste, leaves, and crop residue should be strictly banned, and proper waste management systems must be used. Planting more trees in schools, colonies, and roadside areas helps purify the air naturally.
People can also contribute by using bicycles for short distances, switching off engines at traffic signals, and saving electricity. Schools can start “Clean Air Clubs” to teach students how small habits can bring big changes. Awareness campaigns, clean energy programs, and stricter air quality laws can together make a big difference.
If every citizen takes responsibility, metro cities can once again breathe clean and fresh air. A pollution-free city is not just a dream — it is a goal we can achieve with care, cooperation, and commitment for a better future.
