For decades, poet-philosopher and radical environmentalist Derrick Jensen has warned us about the problems of civilization. Yet he’s a tireless activist with hope for the planet’s future.

In the time after, the buffalo come home. At first only a few, shaking snow off their shoulders as they pass from mountain to plain. Big bulls sweep away snowpack to the soft grass beneath; big cows attend to and protect their young. The young themselves delight, like the young everywhere, in the newness of everything they see, smell, taste, touch, and feel.

Wolves follow the buffalo, as do mallards, gadwalls, blue-winged teal, northern shovelers, northern pintails, redheads, canvasbacks, and tundra swans. Prairie dogs come home, bringing with them the rain, and bringing with them ferrets, foxes, hawks, eagles, snakes, and badgers. With all of these come meadowlarks and red-winged blackbirds. With all of these come the tall and short grasses. With these come the prairies.

In the time after, the salmon come home, swimming over broken dams to forests that have never forgotten the feeling of millions of fish turning their rivers black and roiling, filling the rivers so full that sunlight does not reach the bottom of even shallow streams. In the time after, the forests remember a feeling they’ve never forgotten, of embracing these fish that are as much a part of these forests as are cedars and spruce and bobcats and bears.

In the time after, the beavers come home, bringing with them caddisflies and dragonflies, bringing with them ponds and pools and wetlands, bringing home frogs, newts, and fish. Beavers build and build, and restore and restore, working hard to unmake the damage that was done, and to remake forests and rivers and streams and marshes into what they once were, into what they need to be, into what they will be again.

In the time after, plants save the world.
