Foie gras
In 2012, France produced around 19,000 tonnes of foie gras representing 75% of the world's production in that year. This required the force-feeding of around 38 million ducks and geese. World production in 2015 is estimated as 27,000 tonnes.
Dan Barber
In 2008 his TED talk was on foie gras produced without force-feeding on a farm in Spain which he describes as a "Garden of Eden".
