Greece's annual production of olive oil weighs as much as 1,575 blue whales.

Greece, the third-largest olive-oil player in the world after Spain and Italy, produces 300,000 tonnes a year. Ninety percent of that is exported to the European Union.
Fun fact: Some of the olive trees planted in Greece during the 13th century are still producing olives.
