Cheers as endangered turtle sets off on 20-year journey

July 2, 2008

A 68kg sea turtle raised by humans returned to freedom this week after nine years of captivity, swimming away after the veterinarians who cared for her helped steer her toward the ocean.

Humans have raised the turtle, named Dylan, since she was found in August 1998 as a hatchling straggler on Jekyll Island’s beach, left behind by her nest mates. She spent years at two nature centres before moving to the Georgia Aquarium, and later, the Georgia Sea Turtle Center at Jekyll Island.

The caretakers took the turtle to within 3m of the water and she scooted right in as about 300 people watched from the beach. She took an immediate right turn, swimming parallel to the beach. Terry Norton, head veterinarian at the Sea Turtle Center, helped turn her back out to sea. (more…)

Coral Reef Alliance

June 30, 2008

“Working Together to Keep Coral Reefs Alive” – Nature has long challenged the hardiness of our reef communities but has never quite managed to completely snuff out the entire life force. The ancestors of today’s reef-building corals go back as far as 200 million years and have even survived the catastrophe that wiped out the dinosaurs. Continents may have shifted, sea levels may have risen and fallen but these stalwart reef survivors always managed to regroup and form new communities. At least until now.

In modern times, humans are collectively the coral colonies most effective predators. Holiday makers break bits off as souvenirs, shops sell them as treasures, swimmers stand on them for respite, divers crush them with flippers and boat operators drag anchors across the top of them. On a larger scale, the use of ‘rock-hopping’ nets and bottom-trawling fishing equipment, the grounding of boats, the use of cyanide or dynamite to fish and sediment run-off due to deforestation, are all taking their toll on the well-being of this living eco-system.

Tidal Turbines the Way Forward

June 30, 2008

Renewable energy enthusiasts across the world were recently focused on Northern Ireland’s Strangford Lough, for the installation of the first ever commercial tidal turbine system. Pioneering developer Marine Current Turbines, are behind the SeaGen system, backed by investments from ethical specialists, Triodos Bank and its clean energy investment fund, Triodos Renewables.

The UK has a massive potential for marine energy, which could provide a fifth of the country’s electricity – the proportion nuclear currently provides. The idea of generating power from the sea is moving from the drawing boards and becoming a reality but it is not without its challenges. (more…)
