From Baku, Azerbaijan, NPR's Anne Garrels reports on the possibility of a caviar shortage in the future due to environmental threats to the sturgeon fish that produces the delicacy. Most of the world's caviar comes from the Caspian sea, near Baku. Garrels reports since the break up of the Soviet Union, pollution in the Caspian and illegal fishing have increased...both of which are threats to the caviar producing sturgeons.
