## What is Reef Hero?

Help a coral reef and its inhabitants survive threats from pollution and rising ocean temperatures. Chase away dangers like boat anchors or fish collectors with bubble shots. Get rid of plastic waste, ghost nets, or toxic run-off. Monitor the water temperature and bring it down by collecting CO2.  As in the real world, the reef will change as its health deteriorates: Stress, coral bleaching, loss of fish and eventually a dead underwater landscape means "Game Over". Keep the reef healthy and alive - which is getting harder every day!
