Widely known as "rainforests of the sea", coral reefs are the largest structures on earth of biological origin. Coral reefs support some of the most biodiverse ecosystems on the planet. Thousands of marine animals depend on coral reefs for survival, including some species of sea turtles, fish, crabs, shrimp, jellyfish, sea birds, starfish, and more. Not only beneficial for marine life, coral reefs are also produce up to 85% of the oxygen in the air humans breathe - a shocking fact that not everyone's aware of.
Despite all the good things coral reefs have done for humans and marine wildlife, unfortunately, 25% of coral reefs all over the world are irrevocably damaged. Destructive fishing practices, coral mining, climate change and pollution  are some of the reasons behind their plight.
