Coral reefs are threatened by massive changes throughout the oceans of the world: with rising seas, warming oceans, ocean acidification, overfishing of fish that keep the coral ecosystems in balance... We are only beginning to grasp how dire the situation really is.
Here's an excellent short video that does a great job of putting much of this into context: “Polyps in Peril” video from WRI (World Resources Institute) is like a 101 introduction to corals. It features Celine Cousteau and the artwork of Jim Toomey. Highly recommended!!
