Coral Relief: Learn

A bit of “founding fatherly– wisdom from James Madison:

Knowledge will forever govern ignorance; and a people who mean to be their own governors must arm themselves with the power which knowledge gives.

In that spirit we've compiled a list of facts (the cold, hard kind) about what corals are and how they are beneficial. So arm yourselves with this good knowledge:

• Contrary to popular belief, corals are actually animals. They are made up of tiny polyps that live symbiotically with zooxanthellae algae that grow within the coral's own tissue. This algae provides the coral with food and is what gives it color. These individual corals reproduce both sexually and asexually to form reefs.
• Reefs are home to 25 percent of all marine life equaling over two million different species.
• Ten percent of the world's diet comes from reef fish and many poor and developing countries rely on local reefs for more than a quarter of their protein.
• Coral reefs are an enormous part of local and global economies. In the state of Florida alone coral-related tourism generated $4.4 billion, while creating over 70,000 jobs in a single year.
• Coral reef species are being used to create new antibiotics and antiviral medicines, as well as bone grafts. They also show promise for treating leukemia, skin, and other kinds of cancer.
• Large reefs protect shorelines from excessive wave action, violent storms and floods, helping to prevent death, erosion, and property loss.

.

And here are some of the not-so-smiley causes of destruction:

• Dynamite and cyanide fishing: Yes, people use these two things to catch fish on the reefs. Their destructive impact should be obvious.
• Overfishing: The loss of a particular type of fish to the seafood trade can harm the ecological balance and be devastating to a coral reef.
• Runoff: Sediment from nearby development can get into the water and quickly destroy entire reef systems.
• Collection: Fish are caught and corals are harvested for the aquarium trade, calcium supplements, mortar and souvenirs.
• Global warming: A biggie. While many coral species are physically very hardy, a rise in ocean temperatures of only one or two degrees can cause massive coral bleaching, a condition where the algae dies off and the corals turn white and often die. In addition, warmer waters mean bigger hurricanes, which can pound coastal regions and do enormous damage to reefs.

So now you know a little about these underwater paradises and their frailty, but to quote Goethe: “Knowing is not enough; we must apply!”
