The document discusses three main types of pollution: air, water, and land. It provides introductions and overviews of each type of pollution, along with their causes, effects, and methods of prevention. The causes of air pollution include industries, vehicles, and burning of wastes, which produce harmful gases and affect human health, plants and animals. Water pollution is caused by disposal of untreated wastes into rivers and oceans, making the water unsafe for use. Land pollution occurs through waste dumping and makes the soil infertile and prone to erosion. Prevention methods include planting trees, using cleaner fuels, and proper waste disposal.
