Dugongs and Sea Turtles in Crisis on Great Barrier Reef
Hundreds of miles of beach are seeing unprecedented numbers of dead or dying dugongs and sea turtles off the Great Barrier Reef. It is believed to be a result of a cyclone and flooding that have afflicted Australia within the last year, destroying grass beds that the turtles and dugongs depend on for survival. These animals are solely responsible for managing the seabeds, often referred to as the “lawnmowers of the sea.” Without the grasses, the animals starve and die, and without the animals, the ecosystem faces a real threat of collapse.
Activist Will Intentionally Attract Sharks in 30-Mile Dive
In an effort to raise awareness of the state of the ocean near southern California, world-renown diver and environmental activist Scott Cassell will attempt a record-breaking 30 mile dive from Catalina Island to Los Angeles on September 17. In addition to trying for the new record, he will be fitted with an acoustic shark attractor. The waters of the Catalina Channel were at one time filled with many shark species, but on this dive, Cassell may only see a few. The dive will be filmed and streamed online for people to observe the mission, and as a way to document the current shark populations in the Channel.
Coral Reefs Predicted to Be Extinct in This Century
Scientists are predicting that coral reefs will be the first entire ecosystem that have been destroyed by human activity. With increasing levels of CO2 in our atmosphere raising the ocean’s acidity, pollution, overfishing, and development, corals are becoming more subject to bleaching and die-off than ever before. Many scientists believe that our current rate of activity that contributes to the coral’s decline could result in a massive widespread die-off by the end of the century.
