Richard Branson has discovered plastic on the backside of the world’s greatest ocean sinkhole.
The billionaire dove into the abyss with Fabien Cousteau, the grandson of French explorer Jacques Cousteau, and Nationwide Geographic explorer Erika Bergman on the finish of final yr. In a weblog put up concerning the journey, he has mentioned the invention of bottles on the backside of the Nice Blue Gap exhibits the good have to “eliminate single use plastic,” including that it has change into the “scourge of the ocean.”

The Nice Blue Gap, off the coast of Belize, is sort of 1,000 ft throughout and 410 ft deep. It’s a part of the UNESCO World Heritage Web site the Belize Barrier Reef Reserve System (BBRRS). It’s on the heart of an atoll referred to as the Lighthouse Reef.
The Nice Blue Gap shaped as a limestone cave tons of of 1000’s of years in the past, when sea ranges have been far decrease. On the finish of the final ice age, sea ranges rose by round 300 ft, submerging the cave to change into the pure marvel it’s immediately. The positioning turned well-known in 1971 when Jacques Cousteau explored it, declaring it one of many prime 5 scuba diving websites on the earth.
Branson went to the Nice Blue Gap final month and broadcast the dive on the Discovery Channel. In a subsequent weblog put up, Branson wrote: “We travelled about 10 minutes within the submarine into the Blue Gap after which began edging down the wall of the outlet. The very first thing we got here throughout was a large wall of big stalactites, which have been breathtakingly stunning.
“The Blue Gap is fabricated from a posh system of caves that after shaped on dry land. It’s proof of how oceans can rise shortly and catastrophically. Sea ranges have been as soon as tons of of ft decrease. 10,000 years in the past the ocean stage rose by about 300 ft when plenty of ice melted all over the world. At 300 ft down you might see the change within the rock the place it was land and changed into sea. It was one of many starkest reminders of the hazard of local weather change I’ve ever seen.”
Persevering with, he mentioned the three divers finally received to the thick layer of hydrogen sulphide—a colourless, poisonous fuel that has shaped over centuries. Under this, the workforce discovered creatures that had fallen into the outlet and died after operating out of oxygen.
“As for the legendary monsters of the deep? Properly, the true monsters going through the ocean are local weather change—and plastic,” Branson wrote. “Sadly, we noticed plastic bottles on the backside of the outlet, which is an actual scourge of the ocean. We’ve all received to eliminate single-use plastic.”
The scientific workforce working with Branson will now be producing a 3D view of the Nice Blue gap. They’re additionally concerned in Ocean Unite—a conservation group that hopes to guard 30 % of the ocean by 2030.
The divers’ discovering that plastic has entered the Nice Blue Gap shouldn’t come as an enormous shock. Mass manufacturing of plastic began within the 1940s and 50s. In 2017, scientists on the College of Georgia introduced round 8.three billion tons of plastic had been made—most of which has been discarded. Plastic has been present in deep sea sediments three miles under the floor of the ocean. It has been present in Arctic sea ice and on Swiss mountains.
Extra lately, scientists introduced plastic particles could be present in human feces throughout the globe. Philipp Schwabl, lead creator of the analysis, mentioned: “It’s doubtless that the quantity of plastic contamination could rise additional if mankind doesn’t change the present scenario.”
