this article is not entirely accurate. not all foie gras is made through the forced feeding of ducks. The following statements made by this article are either inaccurate or wrong.

1. Not all foie gras is made through force feeding. Duck raisers have found that if they wait until the winter harvest to slaughter the ducks they have a naturally fatty liver. Hence no need for force feeding.
2. Foie Gras costs about $30 a pound -- very expensive so when the article says that more than a 1000 restaurants have signed the petition I seriously doubt more than a 100 restuarants in ny serve or have served dishes with foie gras. You will only find this dish in the most expensive of restuarants so have more than a 1000 people signed the pledge? sure that's possible, but what does it matter if your local dennys, mcdonalds, street meat vender or olive garden signed this petition. They'd never use foie gras anyway.
3. some places have banned the force feeding of ducks -- but they have not banned foie gras. As they realize that it can be made ethically. If foie gras was banned restuarants and stores would simply change its name. "no no officer that's not foie gras -- its something new -- its blah gras
