Great Barrier Reef coral has been reduced to half since the 80's

A new study has found coral cover in the Great Barrier Reef has been reduced to half of what it was in the 1980s.

Researchers at the Australian Institute for Marine Science found that total coral cover in the region dropped from 28% in 1985 to 13.8% in 2012.

In effect, it means the total coral coverage has dropped by 50.7%.

Researchers say cyclones are responsible for 48% of the loss, while crown-of-thorns starfish represent 42% of the total and coral bleaching the remaining 10%.
