The Netherlands-based nonprofit the Ocean Cleanup says its latest prototype was able to capture and hold debris ranging in size from huge, abandoned fishing gear, known as “ghost nets,” to tiny microplastics as small as 1 millimeter.
…The Ocean Cleanup system is a U-shaped barrier with a net-like skirt that hangs below the surface of the water. It moves with the current and collects faster moving plastics as they float by. Fish and other animals will be able to swim beneath it.
The new prototype added a parachute anchor to slow the system and increased the size of a cork line on top of the skirt to keep the plastic from washing over it.
It’s been deployed in “The Great Pacific Garbage Patch” — a concentration of trash located between Hawaii and California that’s about double the size of Texas, or three times the size of France.
Ocean Cleanup plans to build a fleet of these devices, and predicts it will be able to reduce the size of the patch by half every five years.
During closing statements, Biden had the line of the night: “Look, I’m like plastic straws. I’ve been around forever; I’ve always worked, but now you’re mad at me?”
Democratic presidential candidate Pete Buttigieg inaccurately said that “we could lose half the world’s oxygen because of what’s going on in the oceans.”
…Climate change does pose a threat to oceans, including by reducing the amount of dissolved oxygen in the water, which in some places could be cut in half. But globally, oceans are projected to lose only 1%-7% of their oxygen, and the world’s atmospheric oxygen supply is not at risk.
…The Pono tourism movement. “Pono” is a Hawaiian word having a multi-faceted meaning, but, concisely, it connotes an ethos of respect, uprightness, prosperity and well-being.
“Many travelers visiting the Hawaiian Islands don’t necessarily understand why we stay on the trail when we hike, why we care about protecting our reefs, and many of the dangers they need to be mindful of,” said Jay Talwar, HVCB’s chief marketing officer. “Rather than scold them, we felt that, if our residents shared the ‘whys’ behind appropriate behavior, then most visitors would follow along; in other words, if we don’t show them the trail, how can we expect them to stay on it? That’s what our new Kuleana Campaign aims to do.”
