SAN DIEGO (KGTV/CNS) – San Diego City Council Monday passed a proposal that bans Styrofoam and single-use plastics in a 5-3 vote. In July, the City Council Rules Committee voted 3-2 in favor of prohibiting the use and sale of containers and other items made with Styrofoam.The measure, proposed by Councilman Chris Ward, prohibits the use and sale of egg cartons, food service containers, coolers, ice chests, pool or beach toys, mooring buoys and navigation markers made partially or completely of polystyrene foam, commonly called by the brand name Styrofoam.The city's Environmental Services Department must also provide a list of safe, affordable alternatives to polystyrene products should the ban go into effect.Polystyrene products don't degrade the way more natural products do, taking hundreds of years to break down. Because of this long life span, marine and terrestrial fauna can and do mistake polystyrene for food."Our growing reliance on disposable plastic to fuel our ‘culture of convenience' is not without cost. Globally, an average of eight million tons of plastic ends up in the ocean," said Roger Kube, a policy adviser with the 5 Gyres Institute, when Ward introduced the proposal in May. "Once there, sunlight and currents shred plastic debris into smaller particles called microplastics, which absorb and concentrate toxic chemicals up the marine food chain and into our bodies. From plankton to fish, and to humans that eat seafood, plastic pollution is changing the very chemistry of life."Opponents of the ban claim it will have a disproportionately negative effect on local restaurants who may not be able to afford more expensive alternatives to polystyrene containers the way larger chain restaurants can. A study by the California Restaurant Association, San Diego Chapter, found that the ban could force small food service businesses to spend up to 145 percent more for polystyrene alternatives like compostable paper."We're opposed to the ban because polystyrene is a recyclable product," said Chris Duggan, the San Diego chapter's director of local government affairs. Duggan compared polystyrene's potential for reuse to that of an empty pizza box or a used paper plate and noted that polystyrene can be and is recycled into things like crown molding.Restaurant owners in City Council District 4, represented by Myrtle Cole, pushed back on the proposal Friday when they delivered more than 50 letters opposing the ban to Cole's district office. Restaurant owners in District 4 claim that Cole has not met with them despite multiple requests to voice their concerns."The impacts of Styrofoam and single-use plastics are permanent and threaten the health of San Diegans, wildlife, and industries critical to our region," Ward's office said. "Passing this ordinance puts us in line with other California cities on the issue to secure a safe, sustainable future for our marine environment, our children and their families." 2977

SAN DIEGO, Calif. (KGTV) - San Diego County is offering help to families where a grandparent is a sole provider for his/her grandchildren, as that population expands.Through the Department of Health and Human Services, the County offers support groups, events, resources and more to help people in their golden years who are suddenly thrust back into the role of parent.According to the county's website, there are more than 24,000 grandparents in San Diego County who are raising a young child."That's a pretty large number," says Program Manager Tina Emmerick. "But what's really striking for us is we know that's not capturing the whole population."Emmerick says the reasons grandparents wind up providing for their grandchildren vary. In many cases, it's because the parents tested positive for drugs, are incarcerated, have mental health problems or passed away.For the grandparents left to raise the kids, it can be overwhelming."It's difficult," says Martha Lopez. She's been raising her grandson, Jacob since he was born. His mother, Martha's daughter Crystal, tested positive for Methamphetamine during birth and CPS was going to take Jacob away."I didn't want Jake to go anywhere else," says Lopez. "I wanted to make sure that he was well taken care of."I love him, and he deserves the best, and I'm here for him," she says.Lopez says the last six years have been wonderful, raising Jacob as her own. She had to take early retirement from her job at UC San Diego to become a full-time mom again.Jacob has limited contact with his biological mother, who Lopez says still has issues with drugs.Lopez is part of a support group run through the County. It's one of several programs they offer to grandparents raising grandchildren.The county started offering help to this group in 2012. The resources and support have expanded over the years. They now offer four symposiums throughout the year so grandparents can find all the help they need in one place."We can direct them to food banks, legal aid, support groups," says Emmerick. "They're realizing they're not alone in this. There are other families like them. And that broader community can wrap around these families and provide that extra support."The Live Well San Diego initiative and 2-1-1 help the county with the program. 2297

SAN FRANCISCO (AP) — Facebook threatened to block Australian publishers and individuals from sharing news stories on its platform in reaction to an Australian measure that would require it to compensate media organizations for its use of their stories.The social network said the move would force it to pay arbitrary and theoretically unlimited sums for information that makes up only a small fraction of its service.Google has cast the proposed Australian law as a potential threat to individual privacy and a burden that would degrade the quality of its search and YouTube video services, but did not threaten a cutoff.Australia's government hopes the legislation will be passed this year. 699
