Animation for good

Just Tuna is an animated film made for Greenpeace to inform shoppers that they should know exactly what they are buying and the industries and companies they are supporting. John West's sister company Thai Union is guilty of using unsustainable fishing methods and violating human rights through the exploitation of their workers and by contributing to the human trafficking industry. 

Again, it seems that a charity has chosen to use animation to spread awareness because they are aware of it's novelty, that people will appreciate the artistry of the film and perhaps then inadvertently also learn something and spread the message. It also seems that when tackling difficult social issues such as human trafficking, abuse and the death of marine life, animation provides a forum that can delve deeper than live-action film would be able to. It enables a sense of empathy that might not be achieved through a generic documentary-style film. 

In terms of visual language, the monochrome colour scheme and simple lines add to the narrative. They don't make it fussy or too 'pretty' because Greenpeace want to deliver facts, not just a story about tuna in nice animated packaging. 
That said, there are some really beautiful transitions in the film, such as the bars of a jail becoming the barcode on the side of the tin of tuna - a very simple, clear link between the act of buying and consuming to the atrocities committed by the company.
