The use of solid fuels, such as wood, charcoal, and dung, for cooking and heating, is a major source of air pollution in developing countries. People rely on these fuels in many rural areas because they are cheaper and more readily available than cleaner alternatives such as natural gas and electricity. However, the burning of solid fuels produces high levels of indoor air pollution, which can cause respiratory problems and other health issues. It also contributes to outdoor air pollution, as the smoke and particles emitted from burning solid fuels can escape from homes and into the surrounding environment. This makes the use of solid fuels a significant health and environmental concern in developing countries, particularly in low-income communities where access to clean energy sources and technologies is limited.
