Jaherring,
Coral reefs will be gone by the end of the century, according to UN Scientists. This would give coral reefs the dubious accolade of being the first entire ecosystem to have been destroyed by human activity. In the recently published book 'Our Dying Planet', Professor Peter Sale writes that coral reef ecosystems are very likely to disappear by the end of this century, in what would be "a new first for mankind — the 'extinction' of an entire ecosystem".
What a, "blast"!
