Japan’s Environment Ministry has found that Japan’s Sekiseishoko coral reef is 70 percent bleached, with 91 percent at least partially bleached.  Coral bleaching is caused by warming sea temperatures.  The plant portion of the animal coral is expelled and the coral can no longer produce food for itself and it dies and turns ghostly white. Read More…
