Ships sent to clean Great Pacific Garbage Patch in middle of ocean return to SF
Briefly

"Plastic pollution is one of the largest threats our ocean faces today. It's ravaging ecosystems. There are more than 100 species facing extinction because of plastic," said Boyan Slat.
"Once that is secured, we can ramp this up in about two, three years and the clock starts running. We can clear up the patch in potentially just five years," Slat said.
"You have big waves, and you have a harsh environment. And to build something that's actually surviving out there, while at the same time only making sure you're catching plastic and not marine life, that was quite a challenge," Egger said.
"It is a system of netting, cameras and computers powered by artificial intelligence," Egger explained, detailing the technology developed for the cleanup.
