Coral reefs are literally the foundation for much of the life on Earth. These living cities are made up of animals –coral – which exist in symbiosis with algae.
They are home to thousands of species of fish, as well as important to the lives of as many as a billion people who rely on their production of food, their protection of coastal areas, and their attraction for tourists. They’re ancient, too, and have survived for millions of years.
But now coral reefs are under threat, from pollution, changing temperatures, and disease. Alizée Zimmermann, executive director of the Turks & Caicos Reef Fund, says she was startled to see one particular disease, stony coral tissue loss disease, kill off 500-year-old corals in the span of a few weeks.
Her organization has started to preserve coral species, maintaining them in a lab to save them for when they might safely be returned to the sea. It’s a complicated project and they are racing against time to save species before they go extinct. It’s too late for some. The United Nations Environment Program estimates that 14 percent of the world’s corals died between 2009 and 2018. To stop stony coral tissue disease from killing off selected colonies in the ocean, Alizée's team has even had to apply a specially formulated antibiotic to save these creatures and the ecosystem they comprise.
In this episode of One World, One Health, Alizée explains why corals are so important to everyone, and she talks about some of the creative ways she and her colleagues are working to save these animals that are so important to so many.
