For children, global warming is just a word or a topic in a book. They think it may be about hot or unstable weather, the high water level or missing polar bears, etc. Parents try to explain global warming to their kids, but children find it difficult to get a clear grasp and an understanding of this complex phenomenon. To this end, POB designed a board game called Earth Rescue, which directly uses ice and water elements to help children get a feel for the actual scenario and better understand it.
