LOS ANGELES (AP) — It's not exactly the last straw but Los Angeles has ordered restaurants to stop providing the disposable plastic kind unless customers ask for them.The City Council on Friday unanimously passed an ordinance barring restaurants and food trucks from offering plastic straws to customers, even those taking food to go.Drive-through and delivery places can offer the straws but can't automatically provide them.RELATED: San Diego ban on Styrofoam, single-use plastics takes effectFor businesses with 26 employees or more, the law takes effect on April 22, which is Earth Day. All restaurants must comply by October.L.A. becomes the largest U.S. city to pass a law aimed at reducing plastic waste, which is winding up in landfills and the ocean in enormous quantities.California passed a law last year prohibiting full-service restaurants from automatically providing the straws. 901

LOS ANGELES (CNS) - Newly published research indicates there's an almost one-in-four chance the mountain lions living in the Santa Monica and Santa Ana mountains could become extinct in those areas within 50 years as a result of urban encroachment, inbreeding, vehicle strikes, rat poison and wildfire, it was reported today.In the face of such a dire prognosis, what biologists call an extinction vortex, conservationists are considering a desperate and controversial remedy: capturing pumas in one part of the Santa Anas and trucking them across the 15 Freeway so that they can breed with isolated mates on the other side of traffic."Wildlife managers never want to be a shuttle service for wild animals,'' said Justin Dellinger, senior environmental scientist with the Wildlife Investigations Laboratory at the California Department of Fish and Wildlife, the Los Angeles Times reported. But translocation has potential merit in the short term; after all it helped bring the critically endangered Florida panther back from the brink.Mountain lions are not endangered in California, but groups living in the Santa Monica and Santa Ana ranges now find themselves in genetic peril. Separated by freeways and lethal traffic, they are unable to range freely and are growing increasingly inbred, researchers say.In the Santa Monica Mountains, the 101 Freeway exists as a near impenetrable barrier to gene flow for a group of 10 mountain lions; in the Santa Ana Mountains, the 15 Freeway limits the movement of a family of 20 cougars.Sometimes, the animals manage to cross freeways without getting hit. At least seven cougars have crossed the 15 Freeway near Temecula in the last 15 years, and one sired 11 kittens. The fact that only one managed to reproduce, however, shows how difficult it is to diversify the gene pool in the lions still prowling the range.A population viability study published in the journal Ecological Applications predicts extinction probabilities of 16 to 28 percent over the next 50 years for these lions, which have the lowest genetic diversity documented for the specie aside from the critically endangered Florida panther.Study authors note also that wildfire and disease could result in "catastrophic mortality'' and further hasten the animals' disappearance.However, extinction probabilities were significantly reduced when computer models simulated the influence of two immigrant lions per year in areas blocked by development and freeways, according to a team of researchers that included Winston Vickers, an associate veterinarian at the UC Davis Karen C. Drayer Wildlife Health Center, and Seth Riley, an ecologist with the Santa Monica Mountains National Recreation Area, The Times reported. 2731

LOS ANGELES (AP) — As the coronavirus pandemic forced people to stay put, it gave sharks a travel passport and scientists a rare opportunity. Ocean spots cleared of fishing boats and other intrusions saw increased and even unusual marine life behavior, and Discovery Channel’s Shark Week jumped through hoops to capitalize on the brief window. Its 32nd annual Shark Week slate includes a pair of shows taped earlier this year during the lull. The virus-related shows are “Shark Lockdown,” airing at 10 p.m. Eastern on Sunday, and “Abandoned Waters,” airing 8 p.m. Eastern on Monday. A record 24 shows will air during Shark Week, which starts Sunday and continues through Aug. 16. 687

  

LOS ANGELES, (KGTV) – The Bureau of Alcohol, Tobacco, Firearms and Explosives announced that the agency is offering ,000 for information on the whereabouts of stolen firearms believed to be in San Diego.Authorities with the bureau say 18 firearms were stolen from Turner’s Outdoorsman in the early morning hours of May 1.Officials added that one person is already in custody for the theft, but that ATF is asking for help identifying the location of the guns.“Firearms theft from licensed gun dealers is one of the top priorities for ATF,” said McMullan. “Experience shows these guns will likely end up being used in a crime. These guns in the hands of criminals endanger everyone’s safety. With this reward, it is ATF’s hope someone will come forward with information that will lead to the recovery of these firearms.”A full list of guns stolen is below: 866

  

LOS ANGELES (AP) — California’s death count from the coronavirus has surpassed 15,000 even as the state saw widespread improvement in infection levels. A tally by Johns Hopkins University put California’s death toll at 15,026 on Sunday, the fourth highest in the country. New York has suffered by far the most deaths -- 33,081 -- followed New Jersey, which has about half as many. Texas is third. California has had the most confirmed virus cases in the country with about 775,000 but key indicators have fallen dramatically since a spike that started after Memorial Day weekend prompted statewide shutdowns of businesses. 630
