S1-E23 - Walls of Death

In the 1980s, Japan's, South Korea's, and Taiwan’s massive
fishing fleets gained notoriety for their destructive driftnet
fishing. The use of giant driftnets, sometimes tens of kilometers
long, threatened to turn the oceans into deserts. In 1989 the
United States launched a high-seas sting operation, which
culminated in a US coastguard cutter chasing a Taiwanese
fishing boat carrying illegally-caught salmon for 2,700 miles
across the Pacific. This operation would help bring an end to
these “walls of death.”
