Coral Reefs are easily one of the most recognizable ecosystems on the face of our planet, and they are dying fast. Rising ocean temperatures are bleaching many of these beautiful structures and pollution is killing off large sections of the reefs. But, why is this important? Why should we care about the reefs? Here are some of the most important reasons why you should care about our coral reefs.

1. They increase Biodiversity.

Coral reefs are legendary for the sheer amount of biodiversity present in such a small area. Known as the “rainforests of the ocean”, they contain 25 percent of all aquatic species while covering 1 percent of the ocean. Around 2 million species reside in coral reefs, so it’s no surprise that they are famous for their unique life forms. Without biodiversity, organisms’ gene pools shrink. Without large gene pools, the species is more vulnerable to many different changes. Biodiversity is important so the plants and animals in the reefs do not go extinct.

2. They give food.

Coral reefs have plenty of fish, so it comes as no surprise that many people rely on these structures to feed themselves. People who live near the reefs often fish to supplement their diets. Reefs also serve as hatcheries and nurseries for many of the fish species commercially eaten.

3. They make money.

Coral reefs are a major tourist destination. Famous reefs worldwide such as the Great Barrier Reef generate over 375 billion dollars a year, a majority of which is attributed to tourism. Without the reefs, millions of jobs in over 100 countries around the world would be lost.

4. They protect us.

Coral reefs also act as natural barriers against hurricanes, tsunamis, and typhoons. They are the first line of defense against flooding in many coastal areas around the world that lack other protection. In events such as the devastating 2004 Indian Ocean Tsunami, the reefs offered some security to the people living along the coast.
