This essay conceives ecological life as radically dependent, vulnerable, and horrific. Epistemologically speaking, we are quite ignorant of the web of dependency that sustains our lives. Our ecological condition often prevents us from locating and identifying our dependencies and the many ways our actions impact the environment. This is the terror and danger that plagues the Anthropocene. Our ignorance bears an ontological weight that can be drawn out with the concept of trust. Trust, I argue, is not a choice. Trust is a necessity to which we are riveted, and one that is always conditioned by our vulnerability and ignorance. The picture of ecological trust that I paint is not a hopeful one: it is dark, pessimistic, and urgent. It opposes visions of our future that are superstitious and optimistic about our ability to respond effectively to climate change.
