The video explains the process of gavage, where ducks or geese are force-fed using a tube to enlarge their liver up to ten times its normal size. This process is done to produce foie gras, a delicacy made from the liver of these animals. The video highlights the ethical concerns surrounding this practice, as the animals are eventually slaughtered for their liver to be made into pate.
