National Pollution Control Day is observed on 2nd December every year to create awareness about the harmful effects of pollution on our environment and health. This day reminds us to reduce air, water, and soil pollution by using resources carefully and keeping our surroundings clean. It also encourages people, industries, and the government to follow safe practices to prevent accidents and protect nature. By planting trees, saving water, and reducing waste, we can all help make our planet cleaner and safer.
