Australia’s Great Barrier Reef Suffers Most Severe Coral Bleaching

According to scientists, the Great Barrier Reef in Australia witnessed the worst coral bleaching occurrence in March 2021. Researchers at James Cook University in Queensland, Australia made the most recent discovery of coral bleaching. The most recent coral bleaching case is noted to be the result of unusually high temperatures in the region over the last few months. The Great Barrier Reef covers roughly 348,000 square kilometers of area, making it home to the world’s largest array of coral reefs as well as thousands of various kinds of marine life. Coral is a group of small aquatic organisms that work together to build large, hard structures known as reefs. When the ocean water becomes too warm, corals release the protective algae that live in their tissues, resulting in bleaching. The method turns corals white and makes them sick, killing them in some situations. Reefs are vital to the ocean’s health and all the life it holds.
