Eco-economic decoupling means that we can have a strong economy without causing too much damage to the environment. It's like having a big, strong city with lots of buildings and businesses, but not using too much energy or polluting the air. We can do this by using green energy sources like solar power, wind power, and other renewable sources. We can also reduce the amount of waste we create, like recycling more and using less plastic. These steps can help us stay healthy and protect our planet.
