Scientists reckon the world's coral is disappearing so fast they should freeze samples of it for the future.
They say that climate change is causing coral reefs to die off really quickly, because of changes to the water temperature and acidity.
The plan would be to freeze the coral, store it and then put it back into the oceans later on.
Coral is really important because loads of fish and other animals live in and around the reefs.
Millions of people also need the coral reefs to make money.
In a meeting in Denmark, scientists said that most coral reefs will not survive, even if tough rules to try to stop climate change are put in place.
