The city of San Francisco is on the verge of banning use of the plastic grocery bags that have been a marvel (for their carrying capacity) and a plague for 30 years. The bags were outlawed in South Africa in 2003, they are banned in Bangladesh (where they were blamed for causing flooding during monsoons by clogging drains) and Taiwan. Ireland imposed a 19-cent per bag tax five years ago, and reduced plastic bag consumption 90 percent. Alaskans have actually been ahead of Californians in this particular environmental effort: The bags are banned in at least 30 villages and towns in Alaska, including the towns of Emmonak, Galena, and Kotlik. And a ban on the plastic sacks goes into effect later this year in Paris; they are outlawed in all of France starting Jan. 1, 2010.
Across the landscape, where they snag on everything and flutter in the breeze, they are a discouraging visual pollutant. And while their energy and solid waste impact may be modest, they should also be an easy habit to kick.
