Indoor air pollution is when there are bad things in the air inside a house or building that can hurt people's health. In developing nations, many people use things like wood, coal, and animal dung to cook their food and keep their homes warm. While these things may work well for those purposes, they also give off harmful smoke that can make people sick.
This pollution can cause different problems for different people. Some people might start coughing and have trouble breathing, especially if they already have asthma or other lung problems. Other people might get infections, like pneumonia, more easily because their immune systems aren't as strong.
One way to stop this pollution is to use cleaner cooking stoves and fuels. For example, some stoves are designed to burn wood more efficiently, which can reduce the amount of smoke that's produced. Other stoves use fuels like natural gas or propane instead of coal or dung, which can also help.
Governments and organizations are working to promote these cleaner options and make them more accessible to people in developing nations. By doing so, we can help protect people's health and make sure everyone has access to safe, clean air to breathe.
