Even marine parks that don't source dolphins from Taiji help create demand, and pressure similar institutions - who may not care as much about welfare - into purchasing them.
"After the audience goes home, this is what it's like," the volunteer says in the clip - she's cut off for a moment by a dolphin lifting her head and crying out. "If ever there was a reason to take the pledge not to buy a ticket to a whale or dolphin show, surely this is it."
"This is just so depressing to see something so beautiful living in so much horror," she added.
To help these dolphins, and to stop the cycle, you can take a pledge to avoid dolphin shows, donate to The Dolphin Project to support the Cove Monitor team, and even volunteer to go to Taiji yourself. Click here to find out other ways to help.
