Some of my best holiday memories are linked to snorkeling in areas with great coral reefs. I returned at one of those a few years later, and lots of it had already died out. As much as I don't believe we can reverse the warming of the oceans at this point of time, I do hope we'll find ways to at least make some of the remaining ones more resistant to changes in water temperature. It'd be nice if I can snorkel there one day with my son when he's a few years older.
