Somewhere off the coast of Thailand, “ghost ships” bump and crash along the choppy waves scrapping the sea floor with nets that spare nothing. Pulling up these illegal hauls in shifts that sometimes last 20 hours are thousands of migrant fishermen, many of whom have been forced into indentured servitude or kidnapped.
