Coral reefs are one of the most vital components of maintaing the health of our oceans! These "lungs of the ocean", however, are under direct threat due to climate change, ocean acidification, temperature rise, and pollution. This is creating mass biodiversity loss and "coral graveyards" around the world. We travelled to Key Largo, Florida, USA to visit the Coral Restoration Foundation, the largest coral restoration organisation in the world doing its part to save these essential creatures!
