Marine biologist, Dr. Christian Heesch, has serious concerns about the marine bleaching that is devastating coral reefs around the world. Changes in water temperatures, mostly thought to be a result of climate change, cause the coral reefs to lose their colors and appear bleached. The color change is not the issue of importance, but the fact that the bleaching illustrates a high level of stress on the coral itself. When coral becomes stressed to this level, it does not grow at its normal rate.
