Greenpeace New Zealand activists shut down the the heart of cat food giant Whiskas’ Australasian operations, after Mars confirmed to the organisation that it sources tuna from Thai Union, a seafood company that has been connected to slavery and destructive fishing methods. Activists chained themselves to a Greenpeace truck, branded with the Thai Union logo, blockading the entrance to Whiskas’ cat food factory. Greenpeace/Nigel Marple
