Happy Planet Index

The Happy Planet Index is a way of measuring how happy a place is. It looks at things like how long people live, how much they can do, and how much of the planet's resources they use. It tries to measure how good we're doing as a planet, both for ourselves and for the environment. So if a place scores high on the Happy Planet Index, it means the people there are very happy and that the planet is doing well too!
