Only after

Only after all the oceans are polluted
Only after the last fish has been caught
Only after the last coral reef has been destroyed
Only then will you find that money is not everything

What could we do to save the corals from ending up like the dinosaurs?
1-do not litter near coastal areas
2-when you go scuba-diving, leave what you see alone in their natural habitat instead of collecting them for souvenirs.

If everyone is making an effort to save the earth and not to mention the coral reefs, maybe saving gaia or IYOR would not be needed anymore to remind everyone how important it is to save dying corals and the earth.
