Pollution is the introduction of harmful substances into the environment, which can damage the air, water, and land. Common sources of pollution include factories, cars, and plastic waste. When these pollutants are released, they can harm wildlife, plants, and even human health, leading to serious problems like respiratory issues and contaminated drinking water. There are different types of pollution, such as air pollution, water pollution, and soil pollution. Each type affects our planet in unique ways. For example, air pollution can cause smog and respiratory diseases, while water pollution can harm aquatic life and make water unsafe for drinking. Reducing pollution is essential for a healthier planet.
