In January 2010 Leroi presented the BBC4 documentary Aristotle's Lagoon, filmed on the Greek island of Lesvos and suggesting that Aristotle was the world's first scientist and biologist.
The area enclosed by the villages of Eressos, Antissa and Sigri is very dense in fossilized tree trunks and forms the Petrified Forest of Lesvos, which is managed by the Natural History Museum of the Lesvos Petrified Forest.
