Los Angeles is becoming the nation's largest city to ban plastic bags at grocery stores.

FOX News Radio's Sal Giangrasso reports:

The idea is to save the environment.

(Ban Supporter) "We're concerned about all the plastic that ends up in our oceans, waves, and beaches. We have volunteers out there by the hundreds and thousands every weekend, picking up these little pieces of trash."

So, after an ordinance is adopted later this year, Los Angeles will require large stores to phase out plastic bags over six months, then provide free paper bags for another six months.

After that, retailers can charge 10 cents for paper bags. Reusable bags are encouraged, but some complain...

(Ban Opponent) "If they ban our plastic bags, we're going to end up with no job. We're going to end up on the unemployment line and I need to support my kids."

Lobbyists for manufacturers and union employees say a ban could cost several hundred local jobs.

Editor's Note: Small retailers would have a year to phase out plastic, and people receiving government assistance would be exempt from the future bag fee.
