I think this is very concerning and of course tragic. I watched ââ"šÂ¬Ã…"œthe coral reef adventureââ"šÂ¬Ã‚ last night and it was said that in approximately 30 years the Great Barrier Reef will die completely if the issue is not addressed immediately. I may be exaggerating but I see it as an ecological disaster which will impact marine, and may be other, life around the planet.
