HAWA - The Game

"In the Hawa game, players protect the digital trees they plant and grow from carbon dioxide monsters by planting real trees in their neighborhoods. The goal of Hawa is simple: grow as big as possible so that you can protect yourself from monsters who want to eat up all of your carbon dioxide emissions!
You can play games and help protect the planet. You can also help protect forests, rainforests, and other types of trees. The more people who do this, the better! If everyone plays Hawa and helps protect our digital trees then we will be able to stop carbon dioxide monsters from taking over our world as we know it today!"
