Air pollution is caused by the accumulation of toxic gases in the atmosphere from sources like the burning of fossil fuels, industrial emissions, burning of rubbish, and deforestation. Effects of air pollution include acid rain, injuries to skin and lungs, smog, melting poles, increased temperatures, and rising sea levels. To reduce air pollution, individuals should conserve energy, use public transportation, and reduce plastic use. Companies can take actions like installing filters, using renewable energy, and eco-friendly materials. Governments should pass stricter laws, enforce recycling, and require industries to use environmentally friendly practices.
