In the Amazon, he rides the world’s longest tidal bore. In the beginning, there were no oceans: they are thought to have gradually formed from volcano steam and melted comet ice. Change continues today: a new sea is forming in Ethiopia, which will separate East Africa from the mainland, and the Mediterranean is drying up.
