Pollution refers to the presence of harmful substances or contaminants in the environment. It's the introduction of pollutants that degrade the quality of air, water, and land. Imagine smog hanging over a city 🌆– that's air pollution. It often involves human activities that release harmful waste products. Unlike natural impurities, pollution is caused by human actions. It can have devastating effects on ecosystems and human health. It's like a toxic cloud hanging over everything.
