Okay kiddo, so in 2011, all the leaders from different countries came together to talk about something really important. You see, sometimes things we do can make the Earth get warmer and warmer, and that's not good because it can cause lots of problems like floods, droughts, and bad weather.
So all these leaders wanted to make a plan to help stop the Earth from getting too warm. They talked about different ways to use less energy and electricity, and how to not put as much pollution into the air. They also talked about how some countries are more responsible for making the Earth warm than others, and how they can work together to make things better.
It was a big meeting that lasted for many days and there were lots of different ideas and opinions. Eventually, they came up with a plan called the "Durban Platform for Enhanced Action" which meant that countries agreed to work together to make the Earth a healthier and better place for everyone. It was an important step forward in helping protect our planet for the future.
