The Bamako Convention is like a big set of rules that lots of countries agreed to follow, kind of like how when you're playing a game with friends, you all agree to follow the same rules so that everyone is playing fair.
But instead of a game, the Bamako Convention is all about protecting people and the environment in Africa from harmful things called hazardous waste. Hazardous waste is garbage that can be really dangerous if it's not handled properly, like chemicals that can hurt people or make animals and plants sick.
The countries who signed the Bamako Convention all agreed to work together to make sure hazardous waste is properly handled and disposed of. They also agreed to share information and help each other out if there's a hazardous waste problem in one country that could affect others.
This is really important because hazardous waste can be really bad for people's health and the environment. By following the rules of the Bamako Convention, the countries that signed it are working to keep each other safe and healthy.
