SAN DIEGO, Calif. — For months, we’ve seen face masks in places they shouldn’t be: storm drains, streets, beaches, and parks.Now, we’re learning just how many could be flooding our oceans.“Once plastic enters the marine environment, it’s very difficult to move," said Dr. Teale Phelps Bondaroff, director of research for OceansAsia. The marine conservation group has been tracking the number of face masks washing up on a remote island south of Hong Kong since the pandemic started. “About six weeks after COVID hit Hong Kong, so late February, we began finding masks, and lots of masks," said Bondaroff. “What’s remarkable is we weren’t finding face masks before COVID.”Masks are made with polypropylene, which Bondaroff describes as thin fibers of plastic."The fact that we are starting to find masks that are breaking up indicates that this is a real problem, that microplastics are being produced by masks," he said.These tiny pieces of plastic can remain in the ocean for hundreds of years, threatening fish and even polluting the air.“The question that we couldn’t answer was how many are entering our oceans? We just didn’t know," said Dr. Bondaroff. OceansAsia launched a study to find the answer and recently shared its findings. Of the estimated 52 billion masks manufactured globally in 2020, it's believed 1.56 billion will enter our oceans this year, resulting in an additional 4,680 to 6,240 metric tonnes of marine plastic pollutionBondaroff says the report used a conservative loss rate of 3 percent, and the average weight of 3 to 4 grams for a single-use polypropylene surgical face mask, to arrive at the estimate.“The 1.56 billion face masks that have entered our oceans in 2020 are there for the long run. They will remain in the ocean for 450 years or more, and they’ll break into smaller pieces.”The report notes global sales of face masks surged from around 0 million in 2019 to 6 billion in 2020.“That’s important, we need to keep people safe, but at the same time that has a lasting impact on our environment, and we’re seeing that on the beaches," said Bondaroff. And he says, unfortunately, this problem makes up only a small fraction of the plastic pollution invading our oceans.The report asks people to wear reusable masks whenever possible, dispose of masks responsibly and reduce their overall consumption of single-use plastic. It also calls on governments to:Implement policies designed to encourage the use of reusable masks, such as releasing guidelines regarding the proper manufacture and use of reusable masks.Foster innovation and the development of sustainable alternatives to single-use plastic masks.Discourage littering by increasing fines, and educate the public about responsible ways to dispose of masks.Repair and improve waste management systems to reduce losses and spillage. 2840

SAN FRANCISCO (AP) -- California wildlife regulators have postponed the start of the commercial Dungeness crab season to protect whales and sea turtles from becoming entangled in fishing gear.The Department of Fish and Wildlife announced Wednesday that it's pushing back the Nov. 15 start of the season to Dec. 1. The postponement affects fishing zones from Mendocino County north of San Francisco to the Mexican border.The San Francisco Chronicle says 50 humpback whales were spotted in one week last month off the coast of San Francisco and another 25 in the Monterey Bay area.The recreational fishing season will be allowed to open on Saturday. 655

SAN DIEGO (KGTV):SAN DIEGO (KGTV): Ten budding businesses will have a chance for a big boost when they compete for up to ,000 in cash during Thursday night's Quick Pitch Competition.The event, similar to the TV show "Shark Tank," gives each business-owner two minutes to wow the judges.The ten companies range from tech start-ups to medical research companies (For more information on the 10 finalists, click here). They were chosen from around 280 that applied."It's more art than science," says Mike Krenn, the CEO of San Diego Venture Group. They're one of the sponsors of the event. "There were so many companies. We fought long and hard over who were the final 10. But they've all got some momentum going to market, all chasing big opportunities."One company, DoWhop, is an online marketplace to buy and sell experiences around San Diego. It's founder, Rae Lietzau, says winning this competition would mean expanding her workforce and bandwidth on the site."At this stage, every dollar counts," says Lietzau. "Right now it means allowing more people to get paid to do what they love to do."In addition to SD Venture Group, the event is put on by Tech Coast Angels and the John G. Howard Foundation. All three groups work to improve business in the region. Krenn says this year's competition shows how San Diego has become a hub for start-ups."We're really on the upswing," says Krenn. "It's exciting to see a lot of people imported from silicon valley. Everything's trending in the right direction."Krenn also noted that the winning team from 2 years ago went on to raise around million in capital after the competition.Even companies that don't win cash at Quick Pitch usually get a boost from the exposure. The audience is full of venture capitalists and other potential investors."It gives them the ability to get on their radar earlier so when they come back for funding, people are already familiar with them as well as their milestones," says Victoria Laker, the Pitch Chair for Tech Coast Angels.The event starts at 5 pm at Qualcomm Hall. It's sold out for the first time. 2114

  

SAN DIEGO (KGTV)- Thousands of survivors laced up their walking shoes this morning to support breast cancer survivors and others battling the disease.The annual Susan G. Women San Diego Race for the Cure was held in Balboa Park this morning. The main focus of the event is to bring awareness to breast cancer.Organizers say early detections and knowing your family health history can save your life.“When I was 10 my mom was diagnosed with breast cancer. So I’ve been really diligent throughout my whole life in getting mammograms," Survivor Merrilee Neal says. Komen San Diego offers a number of free resources, including free mammograms.“I am a recipient of the Susan G Komen free mammograms and that’s where my breast cancer was detected,’ says survivor Wendy Shurelds.In San Diego, six women are diagnosed with breast cancer each day. The state of California and the Komen Foundation teamed up for an initiative, called “The Circle of Promise,” to educate women.“The Circle of Promise was created for African American women, due to the fact that the African American women mortality rate is 41% higher in San Diego than any other race.”The goal for the event was 5,000. The funds raised are used to support patients around San Diego county and research in the U.S. 1289

  

SAN FRANCISCO (AP) — A woman was drunk when she drove her large family off a Northern California cliff last month and her wife and several children had large amounts of a drug in their systems that can cause drowsiness, authorities said Friday.Police had previously said they believed the Hart family died in a suicide plunge from a scenic overlook. The crash happened just days after authorities in Washington state opened an investigation following allegations the children were being neglected.Preliminary toxicology tests found Jennifer Hart had an alcohol level of 0.102, said California Patrol Capt. Bruce Carpenter. California drivers are considered drunk with a level of 0.08 or higher.Toxicology tests also found that her wife Sarah Hart and two of their children had "a significant amount" of an ingredient commonly found in the allergy drug Benadryl, which can make people sleepy. Toxicology results for a third child killed are still pending, Carpenter said.Carpenter said none of the car's occupants were wearing seatbelts.Sarah and Jennifer Hart and their six adopted children were believed to be in the family's SUV when it plunged off a cliff in Mendocino County, more than 160 miles (250 kilometers) north of San Francisco.Authorities have said data from the vehicle's software suggested the crash was deliberate, though the California Highway Patrol has not concluded why the vehicle went off an ocean overlook on a rugged part of coastline. A specialized team of accident investigators is trying to figure that out with help from the FBI, Carpenter said."We believe that the Hart incident was in fact intentional," he said.Carpenter said the family stopped in the small town of Naselle, Washington, about 80 miles (128 kilometers) northwest of their Woodland, Washington, home, during their drive to the California cliff. But investigators are still trying to determine why they stopped in Naselle, which added an hour and a half to their trip, and whether they contacted anyone. Naselle is near U.S. Highway 101, a popular, scenic route along the coast.Five bodies were found March 26 near the small city of Mendocino, a few days after Washington state authorities began investigating the Harts for possible child neglect, but three of their children were not immediately recovered from the scene.Two more are missing and another body has been found but not identified.The 100-foot (31-meter) drop killed the women, both 39, and their children Markis Hart, 19; Jeremiah Hart, 14; and Abigail Hart, 14. Hannah Hart, 16; Devonte Hart, 15; and Sierra Hart, 12, have not been found.Devonte drew national attention after he was photographed in tears while hugging a white police officer during a 2014 protest.A neighbor of the Harts in Woodland, Washington, had filed a complaint, saying the children were apparently being deprived of food as punishment.Long before the crash, Sarah Hart pleaded guilty in 2011 to a domestic assault charge in Minnesota over what she said was a spanking given to one of her children.And authorities have said social services officials in Oregon contacted the West Linn Police Department about the family in 2013 while they were living in the area. Alexandra Argyropoulos, who told The Associated Press previously that she contacted Oregon child welfare officials, said in an email Friday that Jennifer Hart ran the household "like a regimented boot camp."Argyropoulos wrote that as a family friend she initially thought Jennifer Hart was a loving mother. But after spending two weeks with the family Argyropoulos said she noticed kindness, love and respect for the children was largely absent. She says the six kids were regularly punished for common childlike and adolescent behavior, such as laughing too loudly.Argyropoulos says the family's story has spurred her to start a petition calling for a national child abuse registry that would alert states of prior reports of abuse.___AP writer Lisa Baumann contributed to this story from Seattle. 4012
