Contraction and Convergence

Contraction and convergence is a concept that explains how people around the world can share the same amount of resources fairly while also reducing their impact on the environment. Think about it this way: imagine you and your friends have a bag of treats to share, but one person keeps taking more than their fair share, while the others aren't getting enough. That's not fair, right?

Now let's say there are lots of people all over the world, and they are all using resources like energy, water, and food. Some countries are using a lot more than others, which means they're taking more than their fair share. This can cause problems for everyone, especially the environment.

That's where contraction and convergence come in. The idea is that everyone should work together to reduce their impact on the environment, by contracting or using less resources overall. And at the same time, everyone should converge or come together to share those resources equally.

So imagine that each country starts out with a certain amount of resources that they can use. Over time, the amount of resources available to each country gets smaller and smaller, so they have to contract and use less. At the same time, every country is trying to use the same amount of resources per person, which means they are converging to a more equal distribution of resources.

The hope is that by using these principles, we can all work together to reduce our impact on the environment and promote fairness and equality around the world.
