In particular, the predicted 0.5 meter [20 inch] rise in sea level by year 2100 will change the nature of physical processes on these reefs, the dominant type in the Hawaiian Islands.

WASHINGTON - The illegal mining of corals off the southwest coast of Sri Lanka permitted far more onshore destruction from the 26 December2004 tsunami than occurred in nearby areas whose coral reefs were intact.

Only in areas where corals were more or less wiped out and no healthy reefs remained nearby to provide a source of new coral larvae, would artificial methods such as coral transplantation be clearly beneficial.
