Coral reefs are a key element of ocean ecosystems.

They provide food and shelter for sea creatures, and they also protect coastlines from storms and erosion.

To measure the success of their program, they looked into calcium carbonate.

Fast forward four years, and the net carbonate budgets have tripled and are indistinguishable from healthy control sites.

The speed of recovery that we saw was incredible, said Lange.

We did not expect a full recovery of reef framework production after only four years.

Ultimately, these findings can prove priceless in undoing some damage to the environment.

However, the researchers note that preventing the damage is more important than ever.
