The Lima Declaration is a special promise that a lot of countries made to each other. They all got together in a big meeting in Lima, which is a city in Peru. During this meeting, the countries talked about how to help each other and work together to make the world a better place.
The countries all agreed to do a few things to make this happen. They promised to protect the Earth, which means they will try to stop pollution and take care of the environment. They also agreed to help each other out by sharing money and resources.
The Lima Declaration is important because it shows that countries can work together and be friends. They want to help each other and make the world better. It's like when you and your friends work together on a project, you can get a lot more done than if you try to do it all by yourself. By working together, the countries can accomplish a lot more than they could on their own and make a brighter future for everyone.
