Scientists and volunteers who have spent the past month gathering data on how much plastic garbage is floating in the Pacific Ocean returned to San Francisco on Sunday and said that most of the trash they found is medium to large-sized pieces, as opposed to tiny ones.
Volunteer crews on 30 boats have been measuring the size and mapping the location of tonnes of plastic waste floating between the US west coast and Hawaii.
“It was a good illustration of why it is such an urgent thing to clean up because if we don’t clean it up soon then we’ll give the big plastic time to break into smaller and smaller pieces,” said Boyan Slat, who has developed a technology that he said could start removing the garbage by 2020.

A ship carrying fishing nets, buckets, buoys and bottles, among other items, and two sailing boats with volunteers who helped collect the garbage samples arrived at San Francisco’s Piers 30-32. The boats went on a 30-day voyage as part of the “Mega Expedition,” a major step in an effort to eventually clean up what is known as the Great Pacific Garbage Patch.
The expedition was sponsored by The Ocean Cleanup, an organization founded by Slat, a 21-year-old innovator from the Netherlands.
Slat said the group would publish a report of its findings by the middle of next year, and after that they hope to test a 1.6km barrier to collect garbage near Japan. The ultimate goal is construction of a 100km barrier in the middle of the Pacific.
He first became passionate about cleaning the oceans of plastic while diving in the Mediterranean Sea five years ago.
“I was diving in Greece and realized that there were more plastic bags than fish, and I wondered why can’t we clean this up,” Slat said.
After dropping out of university after his first six months, Slat dedicated his life to developing the technology the group is to start testing next year.
He has envisioned using long-distance floating barriers that would attach to the seabed and would target swirling ocean currents full of waste and skim garbage from the surface while aquatic life and the currents themselves pass underneath.
After a 2012 Ted Talk about his idea was viewed more than 2 million times, Slat decided to launch a Kickstarter campaign and raised 2 million euros (US$2.3 million) that helped to start his organization.
Soon, his innovative solution got the attention of major philanthropists in Europe and Silicon Valley, including Salesforce.com chief executive officer Marc Benioff, who are helping to pay for the data-gathering efforts and the technology’s development.
A Zurich city councilor has apologized and reportedly sought police protection against threats after she fired a sport pistol at an auction poster of a 14th-century Madonna and child painting, and posted images of their bullet-ridden faces on social media. Green-Liberal party official Sanija Ameti, 32, put the images on Instagram over the weekend before quickly pulling them down. She later wrote on social media that she had been practicing shots from about 10m and only found the poster as “big enough” for a suitable target. “I apologize to the people who were hurt by my post. I deleted it immediately when I
The governor of Ohio is to send law enforcement and millions of dollars in healthcare resources to the city of Springfield as it faces a surge in temporary Haitian migrants. Ohio Governor Mike DeWine on Tuesday said that he does not oppose the Temporary Protected Status program under which about 15,000 Haitians have arrived in the city of about 59,000 people since 2020, but said the federal government must do more to help affected communities. On Monday, Ohio Attorney General Dave Yost directed his office to research legal avenues — including filing a lawsuit — to stop the federal government from sending
At first, Francis Ari Sture thought a human was trying to shove him down the steep Norwegian mountainside. Then he saw the golden eagle land. “We are staring at each other for, maybe, a whole minute,” Sture said on Monday. “I’m trying to think what’s in its mind.” The bird then attacked Sture five more times on Thursday last week, scratching and clawing the 31-year-old bicycle courier’s face and arms over 10 to 15 minutes as he sprinted down the mountain. The same eagle is believed to be responsible for attacks on three other people across a vast mountainous area of southern Norway
Chinese President Xi Jinping (習近平) is to visit Russia next month for a summit of the BRICS bloc of developing economies, Chinese Minister of Foreign Affairs Wang Yi (王毅) said on Thursday, a move that comes as Moscow and Beijing seek to counter the West’s global influence. Xi’s visit to Russia would be his second since the Kremlin sent troops into Ukraine in February 2022. China claims to take a neutral position in the conflict, but it has backed the Kremlin’s contentions that Russia’s action was provoked by the West, and it continues to supply key components needed by Moscow for
