"Single use plastic bags which choke marine life, should be banned or phased out rapidly everywhere. There is simply zero justification for manufacturing them anymore, anywhere," said Achim Steiner, executive director of the U.N. Environment Programme. His office advises U.N. member states on environmental policies.

Steiner's declaration accompanied a UNEP report that identifies plastic as the most pervasive form of ocean litter. According to the report, "Plastic, the most prevalent component of marine debris, poses hazards because it persists so long in the ocean, degrading into tinier and tinier bits that can be consumed by the smallest marine life at the base of the food web."

The ban is already being tested in China, where retailers giving out thin bags can be fined up to $1,464. According to one nationwide survey, 40 billion fewer plastic bags were given out in grocery stores after the law's enactment. In addition, Ireland managed to cut single-use plastic bag consumption 90 percent by levying a fee on each bag that consumers use.

In the United States, only San Francisco has completely banned plastic bags; Los Angeles will do so in 2010. Also, the city council in Washington, D.C., is set to vote on a five-cent-a-bag tax later this month. On first reading, the bill passed unanimously. Similar proposals have failed in New York and Philadelphia.
