SEATTLE (AP) — U.S. scientists said Friday they will investigate why an unusual number of gray whales are washing up dead on West Coast beaches.About 70 whales have been found dead so far this year on the coasts of California, Oregon, Washington and Alaska, the most since 2000. About five more have been discovered on British Columbia beaches. That's a very small fraction of the total number of whales believed to have died, because most simply sink and others wash up in such remote areas they're not recorded.NOAA Fisheries on Friday declared the die-off an "unusual mortality event," providing additional resources to respond to the deaths and triggering the investigation."Many of the whales have been skinny and malnourished, and that suggests they may not have gotten enough to eat during their last feeding season in the Arctic," agency spokesman Michael Milstein told reporters during a conference call.The eastern North Pacific gray whales were removed from the endangered species list in 1994, after recovering from the whaling era.The population has grown significantly in the last decade and is now estimated at 27,000 — the highest since surveys began in 1967. That has raised questions about whether their population has reached the limit of what the environment can sustain. Another theory suggests that the loss of Arctic sea ice due to global warming is a culprit.The whales spend their summers feeding in the Arctic before migrating 10,000 miles (16,000 km) to winter off Mexico. Though they eat all along their route, they are typically thinning by the time they return north along the West Coast each spring.They eat many things, but especially amphipods, tiny shrimp-like creatures that live in sediment on the ocean floor in the Arctic. For many years, researchers noted that fewer calves tended to be born following years when the ice in the Chukchi Sea, north of the Bering Strait between Alaska and Russia, was late to melt. The whales had less time to feast because they couldn't access the feeding area, and thus had less blubber to sustain them on their next migration.Last year, though, the Artic was unusually warm. The whales weren't blocked from the feeding area, and yet are still struggling this year. That has scientists wondering if the loss of sea ice has led to a loss of algae that feed the amphipods. Surveys show the amphipod beds moving farther north, said Sue Moore, a biological oceanographer at the University of Washington."The sea ice has been changing very quickly over the last decade or so," she said. "The whales may have to shift to other prey, such as krill or other things they eat."In an average year, about 35 whales wash up in the U.S.In 2000, more than 100 did, prompting NOAA to declare an "unusual mortality event" then as well. The resulting investigation failed to identify a cause. The die-off followed strong changes in ocean conditions in the mid-1990s, suggesting that warmer water patterns affected the availability of prey, but scientists were often unable to perform necropsies, Moore said."It's sometimes very difficult to get to these whales in a timely fashion," she said. "You can't always get the kind of samples you would need for diagnostic reasons."Since then, researchers have built up an improved network of volunteers and have better educated the public to help report and respond to whale deaths, said Deborah Fauquier, veterinary medical officer at NOAA's Office of Protected Resources. This time around, scientists have been able to perform necropsies on 20 of the whales, she said.John Calambokidis, a research biologist with the Cascadia Research Collective, noted that as the whales search farther afield for food, they've entered areas where they're not normally seen so often, including San Francisco Bay and Puget Sound. That puts them at higher risk of being struck by ships or entangled in fishing gear.Four of the 10 gray whales found dead near San Francisco this year were struck by ships, and a number of shipping companies have slowed their vessels in the area to avoid collisions. 4086

SAN YSIDRO, Calif. -- A quick conversation with a customer is now a rare interaction for border town business owner Sunil Gakhreja.“There is no business. You’ve been in here for 20 minutes and no one’s come in, no one’s even crossed by in front of us,” said Gakhreja.The Department of Homeland Security banned all non-essential travel between the United States and Mexico because of COVID-19.For business owners in the small border town of San Ysidro, about 20 minutes south of San Diego, this closure is suffocating their livelihood.“When they close the border, economically, it affects us a lot. That’s our main bread and butter,” said Gakhreja.The San Ysidro Chamber of Commerce said 95% of the customers in the stores cross the border from Mexico into the U.S. to shop.The chamber reports now that border crossings are restricted—businesses are losing .8 million per day.Gakhreja is no exception. He was forced to lay off the entire staff at his perfume shop.“It’s only me and my wife working. That’s how we can survive.”The family’s entire livelihood hangs on the success of one strip mall on San Ysidro Boulevard. They just opened a pizza shop next door named for Gakhreja’s mother Maya.It’s a tribute he’s desperately trying to keep alive.“We put everything— our soul in there, our money, every single penny we have. I don’t want to let it go down, in any way,” he said.Sunil has been in the United States for more than two decades after immigrating from India.He said this city gave him the chance for a different life than he had growing up.“This country has given me everything,” said Gakhreja. “I am here because of this community. This border town has given me everything: the ability to buy my house, to run my business, I couldn’t be more blessed, but I don’t want to give up my hope. I want to hold on to that last breath that we have.”The San Ysidro Chamber of Commerce is handing out PPE to help small businesses hold on. Packages of hand sanitizer, masks, face shields and gloves will go out to any business that needs it.“Being safe, PPE, distancing ourselves, wearing our masks, that’s the way to protect ourselves,” said Jason Wells of the San Ysidro Chamber of Commerce. “Not being xenophobic and doing things like closing the border.”Gakrehja said this street on the border can’t wait too much longer.“You’re going to lose jobs, people will go into depression, this is our American dream,” he said.Gakrehja is just hoping lawmakers see one thing: in times of turmoil—keeping people apart can cause great pain.“We have to understand we are a great nation, but at this time we need other people’s help too,” he said.The border closure is extended until July 22, 2020. However, for the past several months, the deadline has been extended several times. Business owners fear that will continue to happen. 2833

SEATTLE, Wash. — MacKenzie Scott, the former wife of Amazon founder Jeff Bezos, says she has given away .1 billion in the past four months to hundreds of organizations as part of a giving pledge she announced last year.The Seattle Times reports Scott announced her pandemic-era philanthropy in a Medium post Tuesday, writing that the pandemic has substantially increased the wealth of billionaires, while things have gotten worse for women, people of color and those living in poverty.The philanthropist and author says she asked a team of advisers to help her “accelerate” her 2020 giving with immediate help to those financially gutted by the pandemic.She says the team used a data-driven approach, identifying organizations specifically in communities with high food insecurity, racial inequity and other factors.As a result, Scott says billions of dollars in “gifts” have been given to 384 organizations across all 50 states, Puerto Rico and Washington D.C.“Some are filling basic needs: food banks, emergency relief funds, and support services for those most vulnerable,” wrote Scott. “Others are addressing long-term systemic inequities that have been deepened by the crisis: debt relief, employment training, credit and financial services for under-resourced communities, education for historically marginalized and underserved people, civil rights advocacy groups, and legal defense funds that take on institutional discrimination.”Click here to learn more about which organizations benefited from Scott’s donations. 1534
