After both suing President Donald Trump and launching an activism platform in the name of environmental causes, Patagonia continues its progressive activities by unveiling a new film centered around the threats facing the Balkan rivers. Blue Heart aims to garner protection for the rivers, showcasing the dams that threaten the wildlife, environment and local people.

Over €700 million EUR (nearly $870 million USD) has been poured into the construction of dams in the area, with local governments garnering cash off the back of efforts to channel hydropower energy. According to Patagonia, the dams aren’t clean or efficient, and will only upset the delicate balance of nature in the Balkan Peninsula. Blue Heart takes a closer look at the people fighting displacement due to the proposed 3,000 hydropower projects in the area, exploring the actions that must be taken to shelter the picturesque environment from money-grabbing schemes.

Watch the trailer above and then head over to the brand’s dedicated Blue Heart website for more information on the film and to sign the anti-dam petition.
