The yacht Diversity leaves the harbour of Aqaba, the only coastal town in Jordan. To the right is the Israeli resort of Eilat, framed by barren mountains; in the Red Sea, a boxfish makes leisurely circles in absurdly clear, turquoise water.
The boat soon anchors just offshore, directly in front of Aqaba’s electricity plant, and suddenly everything happens quickly: the passengers don wetsuits, pass around gloves and cloth bags, and then, one by one, dive in. They all have one mission: to collect as much rubbish as possible in 30 minutes.
