Reef restoration provides passion for diver

From an article on CNN.com:

TAMPA, Florida (CNN) -- After witnessing the rapid devastation of a Cayman Island coral reef where he had been diving since childhood, Todd Barber was moved from horror to action.

He gave up a six-figure salary as a marketing consultant and dedicated his life to restoring the world's ocean reef ecosystems.

"I had been following this reef since I had been 14; it was where my first dive was," recalls Barber. "When that one little tiny reef was lost, that sparked something in me. If we lost one and it took that tens of thousands of years to get here, how fast is this happening?"

Barber had caught a small glimpse of a larger global issue -- the destruction of the world's coral reefs -- and it scared him. According to the Nature Conservancy, if the present rate of destruction continues, 70 percent of the world's coral reefs will be destroyed by the year 2050. Not only are they home to 25 percent of all marine fish species, but the organization states that 500 million people rely on coral reefs for their food and livelihoods.

So Barber and his father, a marine biologist and fellow diver, sat down to devise a solution to "put the reef back." What started as a basic idea to shape concrete around a beach ball led to three years of research, testing and prototyping with the help of friends and college professors.

"Our goal was to mimic nature, not dictate nature," says Barber. "And that meant that I couldn't come up with an idea; I had to design something that would fit exactly what the reef required."

The result was what Barber calls a "Reef Ball." Made of concrete engineered to last more than 500 years, Reef Balls are circular structures with a hollow center that serve as a base habitat upon which a natural reef can grow. Portable, inexpensive and environmentally friendly, according to Barber, Reef Balls can be built anywhere and are used to mimic and rehabilitate all forms of oceanic reefs, such as mangrove, oyster and coral reefs. They can also help control erosion and stabilize shorelines.
