L.A. OKs Ban on Plastic Bags at Checkout
from the Los Angeles Times (Registration Required)
Los Angeles became the largest city in the nation to approve a ban on plastic bags at supermarket checkout lines, handing a hard-fought victory to environmentalists and promising to change the way Angelenos do their grocery shopping.
The City Council voted 13 to 1 to phase out plastic bags over the next 16 months at an estimated 7,500 stores, meaning shoppers will need to bring reusable bags or purchase paper bags for 10 cents each.
The ban came after years of campaigning by clean-water advocates who said it would reduce the amount of trash in landfills, the region's waterways and the ocean. They estimate Californians use 12 billion plastic bags a year and that less than 5% of the state's plastic bags are recycled.
