California will soon become the first state in the nation to ban plastic bags at all groceries and most retail stores. NPR's Chris Ziegler reports the bill signed by governor Jerry Brown takes effect next July.

The new law makes it illegal for grocery stores, convenience stores and pharmacies to distribute single-used plastic bags to customers. The bill is mostly aimed to cracking down on pollution in airing plastic bags, littering beaches, clogging drains and creeks. To follow plastic bag, ban has already been in effect in major cities like Los Angeles. When here in LA, you have to bring your own bags, or you can buy a 10-cent paper bag if you forget. Libertarians oppose to this new state-wide law, recalling it an unnecessary government overreach. Along with new restrictions, the bill signed by governor Brown includes 2 million dollars in competitive loans to help business's transition to making reusable shopping bags. Chris Ziegler, NPR News.
