Perhaps feeling the pressure from consistent criticism of their juvenile and immature methods, Greenpeace’s latest Carting Away The Oceans “report” represented a touching effort to show that they could act like grownups by putting out a document that included relatively few full-page pastel illustrations and zero cartoonish fish in top hats. Of course, they never bothered to address the core critique of their previous reports: that they never explain how their policies would actually help the environment, and provide zero transparency on their completely arbitrary scoring system.

The report is still a step up from their usual tactic—getting teenagers in plushy fish costumes to harass families at grocery stores—but the blip in maturity was short-lived. This week representatives from the major tuna companies and sustainability partners are meeting in Bangkok to host discussions on the current state of ongoing efforts. In the name of contributing to the conversation, Greenpeace has decided to… don those plushy costumes again and direct messages at the tuna industry filled with profanity. While this is a family-friendly blog, we can say that both a Twitter  campaign and a number of harassing phone calls have made liberal use of a four letter word that starts with ‘F’ and ends with a ‘K’.

Some habits appear hard to break, and for Greenpeace, ignoring the science and succumbing to the lowest common denominator is such a habit. While the people who actually care about sustainability are hard at work, Greenpeace is content to further marginalize themselves with base comments and streetside harassment. Is it any wonder no one takes them seriously?
