The article that I have found this week is about how ocean scientists will test 50 coral reefs around the world and test ways to limit damage from climate change, pollution and over fishing. They say record breaking heat, pollution and over-fishing threaten to wipe out 90 percent of all reefs by 2050. Last year was the warmest on record which caused damage to coral reefs all around the world. Scientists want to first change the course of coral losses by attempting to safeguard corals. Some ways to do this include establish no fishing zones and cut pollution in coastal seas. The article says that some of the most disastrous effects of climate change are out of sight on the ocean floor. Warm waters can bleach corals by driving away algae. One in four types of fish spend part of their lives in coral reefs.
