Is ozone good or is ozone bad?
"Life in a greenhouse" tells you the odd story of how ozone can be both good and bad, depending on its location.
Your goal in the exciting Ozone Trap-n-Zap game is to balance the ozone in these layers. You need to Trap the ozone where it will help the environment and Zap the ozone where it will hurt the environment. Have fun doing your part to help Earth!
