Dying Coral Reefs
A study released says that coral reefs in the Pacific Ocean are dying faster than previously though. In the past two decades 20 percent of coral has disappeared from the Pacific Ocean. More than 600 square miles of coral reefs has disappeared since the 60’s. Losses in well-protected areas such as the Great Barrier Reef were just as bad as losses in poorly managed areas like the Philippines. The United Nations estimates that nearly a third of all coral has been lost and by 2030 an estimated 60 percent of coral cover will be gone.
There are many reasons behind the decline of coral reefs. Global climate change, storm damage, agricultural runoff, predators and diseases are the main factors influencing this rapid decline. Warming waters cause coral to “bleach” and lose their color, often resulting in death or reduced reproduction. In addition the ocean absorbs carbon from the atmosphere, which causes the ocean to become more acidic and thus dissolving the coral’s calcium skeleton. Agricultural runoff dumps massive amounts of nutrients into the ocean, fueling massive algae blooms that block out light for coral. Overfishing has exacerbated this problem, since no predators are left to feed on algal blooms.
Coral reefs are dying at an unprecedented rate around the world. |
It’s so hard to describe how disheartening this news is to me.
Coral reefs are a source of life for people. Ecotourism and fishing provide money for families to make a living. Coral reef islands are homes for people as they have been for hundred of years. They’re homes to an amazingly diverse group of animals and plants. They’re also a source of amazement and joy to the people that visit them.
I stayed on a coral reef island for a few days when I studied abroad, and I will never forget the amazing things I saw. I was gathering algae for a research project during high tide on the reef and when I looked up I saw a sea turtle hovering in front of me, quietly contemplating me as I slowly reached out and scratched it shell (I’ve been told that sea turtles enjoy having the algae scratched off their shells by divers). I’ve seen eagle rays jump six feet out of the water and silently watched female sea turtles digging nests on the beach. I’ve seen a 600-pound grouper hunting at night and swam beside a five-foot shark. I’ve seen a giant clam the size of a small child and dove through a school of simmering fish. Just floating above the reef and watching the sheer abundance of life weave their way around you as they go about living is indescribable.
I’m unable to do justice to all the crazy things I saw. I’m just telling stories. There are so many things I can’t convey in words. It’s the difference between seeing it on the TV screen and actually experiencing the realness of it. I think there was a point where I just stopped and thought, “This is real”. Before, all I’ve ever seen of the reef was in National Geographic and nature shows I watched as a kid. It’s unbelievable to think that someday, the only things left of coral reefs will be stories, pictures, movies and memories. One day, people won’t be able to go out and see all these things anymore, simply because the reefs will one day cease to exist. They’re already on their way there.
I’ve read too many reports and seen too many news stories on disappearing reefs. Whenever I see another one, all I can think to myself is, “This is unreal.”
