Los Angeles City Council approved an ordinance to outlaw plastic supermarket bags. It is by far the biggest city in America to do so. The measure will come into effect next year and includes a 10-cent charge on paper bags for shoppers who do not bring their own reusable ones.
One in four Californians will live in a city that bans single-use plastic bags once the ban goes into effect.
About $2 million a year is spent to clean up plastic-bag litter in Los Angeles. Sanitation authorities estimate more than 228,000 bags are distributed in the city every hour.
The city plans to hand out one million reusable bags in low-income areas.
