If the ice caps melt the sea level will rise 12 meters and some countries or cities will get flooded and then the population of people will go down.
Also the animals on the ice will have no home.
Some animals will go to cities and they might attack people or people might hunt them down.
We are slowly stopping climate change so please if you have plastic don’t throw it on the ground recycle it and don’t litter.
If you keep littering then the ice will melt and the sea level will go higher and higher.
