If you haven’t used the term “Anthropocene” much, you can be forgiven. The term is of fairly recent origin, and it’s used to describe what some believe is a new geologic age: one in which human activity has changed the earth and its atmosphere. It’s a big idea, one that catches a lot of other ideas in its net—climate change being the most powerful. The idea of the Anthropocene lends more weight to what we already understand are the consequences of human activity. Our impact is not just local, national, or global, but temporal. We’ve literally changed the scale of geologic time.
The awesome consequences of human agency on the land are tough to convey without sounding ponderous, but for the filmmakers Alex Chohlas-Wood and Ben Mendelsohn, who are interested in things like infrastructure, technology, and the human/nature interface, much of the story can be told by the landscapes where these earth-changing processes take place. Which is how they came to make a documentary nominally about dredging, dredge landscapes, and sediment flow: The Fluid and the Solid.
