Which statement best summarizes "Save the Coral Reefs”? Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. In fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. More must be done immediately to save the reefs.

Explanation:

Coral reefs are among the world's most complex habitats, home to thousands, or even millions of marine species. Around one-third of all species of marine fish spend a majority of their lives on coral reefs.  Coral reefs worldwide are steadily decreasing and endangered by a number of factors including pollution, climate change, fishing, and human activities. Unless nothing is attempted to save them, then by the end of the century many coral reefs will no longer survive as functional ecosystems. Via strong protection measures and efficient coral reef resource management, people can reduce some of the risks to reefs posed by local human activities.
