Swimming the Seven Seas - Lewis Pugh

Medieval European sailors and cartographers spoke of the world's "Seven Seas" that they navigated in the name of exploration and commerce. The Euro-centric term has faded in favor of a more global perspective, but in order to better understand the eternal seas that surround the "Old World," South African swimmer and conservationist Lewis Pugh has taken to the water to slowly explore their health. His swim's results are disheartening: the Aegean Sea was full of garbage; the Black Sea blossomed with invasive jellyfish; and he didn't see a single fish in the Adriatic. But Pugh says he found hope in the Red Sea; the waters were full of litter and pale, dead coral, until he swam into a marine protected area. There, he found beautiful, colorful and the vibrant fish life that sustainably fed the Western world for thousands of years.
