The beach in Dakar, Senegal is empty except for a group of singing fishermen, pushing their colorful wooden boat back to shore. The windy weather has kept many on land today – including Mamadou Mbaye, head of Senegal’s fishermen union. He says the sea is depleted of fish because of foreign trawlers, and fishermen often work three straight months in order to make just under $20 a day – half of which goes to expenses like gasoline. And here’s no guarantee they’ll catch something. The fish, he adds, started to go away about ten years ago.
