Shoppers going green despite struggling economy

Despite the worst U.S. recession in decades, sales of organic and sustainable products have continued to grow, experts say, with shoppers willing to spend a few more dollars in a bid to become more green.

U.S. supermarket sales of environmentally sustainable or "ethical" products -- from energy-efficient light bulbs to organic produce -- will rise about 8.7 percent in 2009 to nearly $38 billion, according to a recent study by Packaged Facts, a market research provider.
