World needs oxygen to support life. Unfortunately, world oxygen reserves are being depleted.
The earth needs your help to survive!
Trees release oxygen but buildings and empty soil consume it.
You can grow trees and buildings in your country. You can grow your country by claiming cells next to it. The bigger the country, the more impact your country will have overall.
