Minecraft
Minecraft is a sandbox building game where people can create their own worlds and play with friends.
We built a world with two cities:
One is a polluting city with cars that have gas coming from the exhaust, buildings that are using a lot of energy that is not renewable, and burning fossil fuels. It is a very dirty and polluted environment.
The other city has cars that are all electric vehicles, very safe for the environment, with buildings using solar panels.
