Coral reefs are a biodiversity hotspot for ocean life. Remarkably, about 1/4 of marine species reside in coral reefs.
These are like the rainforests of the oceans. From an environmental standpoint, there’s been a race to protect them.
Not only does overfishing threaten coral reef health, but stress from rising temperature, ocean acidity even sunscreen can harm coral reef.
Scientists argue that coral reefs face extinction in 50 years. So the spotlight is on coral reef.
For example, replanting is just one way scientists are restoring these underwater biodiversity hotspots.
