Coral reefs worth four times as much as UK economy, 'Earth Index' finds

Earth Index is published in the financial sections of newspapers around the world to put nature on the stock exchange, with price for bees, fish and more

Coral reefs are worth 6tn a year in services they provide for people - almost four times as much as the UK economy - an assessment of the value of natural assets has found.

The 'Earth Index' drawn up for BBC Earth also found bees contributed 106bn to the world economy in pollinating crops, and that vultures were worth 1.6bn for clearing up animal carcasses and preventing human health hazards.
