More than 1,100 sea experts want the UN to do something to stop the destruction of the world's deep-sea corals.
Much of the damage is caused by a special type of fishing net that drags along the bottom of the ocean.
It's really good at catching the valuable fish that live in the coral, but wrecks the coral at the same time.
The scientists want to try and work out a better way of fishing the reefs, because if the corals are destroyed there won't be any fish left either.
