The Great Barrier Reef is in rough shape after multiple bleaching events. The Ocean Agency / XL Catlin Seaview Survey Two new studies show that the world's oceans are in dire straits — even more than scientists previously thought. One study found that coral bleaching events, which can kill reefs, are now happening every few years instead of every few decades. And a new review found that oceans are losing oxygen faster than we realized, which could have serious consequences for marine life. Ocean health has a huge impact on human health, so solving these problems is essential. Our world is an ocean planet. The seas support hundreds of millions of people by providing food and jobs around the globe. Ocean plants produce up to 85% of the oxygen in the air we breathe. But a pair of new studies published in the journal Science indicate that the oceans have...
It’s official. The Great Barrier Reef cannot be saved. The prognosis comes from the Australian government’s Reef 2050 advisory committee, made up of experts and scientists responsible for managing the reef’s future. In the more optimistic times of 2015, the committee put out a report on how to best preserve the reef. But now two of the committee’s experts have told the Guardian that the plan is no longer feasible “due to the dramatic impacts of climate change.” Instead, they recommend that the goal be revised to “maintain the ecological function” of the Great Barrier Reef. And the reef may now have a better shot of being listed as a “ World Heritage site in danger ,” a designation the Australian government has fought for for years. Record temperatures have killed almost half of the coral in the Great Barrier Reef One reason for the bleaker forecast for the reef...

#Plastic is one of the most enduring materials we make; it takes an estimated 500 to 1,000 years for it to #degrade, but 50 percent of the plastic we produce is used once and then thrown away. Eight million tons of plastic ends up in the #ocean every year. #oceandebris #plasticpollution #sustainability #goblu3
Facts like this are plentiful, but you get the idea. So, a call to arms. Here are some very easy things to give up in order to curb your contribution to the problem.
#Scubadivers may be more aware of the threats facing #sharks — but we also feel helpless about what we can do. It’s a sobering statistic: Up to 25 percent of the world’s sharks and rays are threatened with #extinction, according to the #IUCN #SharkSpecialistGroup (SSG). Using the #IUCNRedList of #ThreatenedSpecies criteria, the SSG says that of the 1,041 species assessed, 107 rays and 74 sharks are classified as threatened.
