Hi there,
Which was that one documentary that marked you?
For me, it was Earthlings and, more freshly, Seaspiracy.
Recently I was again looking for some food for thought when I discovered WaterBear: a streaming source that focuses on storytelling as a tool to make a difference, and I thought you might like it too.
Next time you are in the mood for some disruptive entertainment, check out some of their +800 documentaries, locally-told stories, NGO campaigns, on-the-ground grassroots outreach, volunteering, eco-travel... all dedicated to the future of our planet, and all totally for free.
