Dam nation

The US is pock-marked with dams that no longer generate power, bridges that can’t hold up a Tata and roads that go nowhere.
They’re not doing nothing, of course. They’re continuing to affect the environment and the immediately surrounding ecology.
So what are we supposed to do with them?

Use them to the environment’s advantage, Martin Doyle says in a Science policy paper about infrastructure decay and ecology restoration.

When dams are removed, like in this photo, it’s been shown that the ecology makes a quick comeback. That’s what happened to the endangerd North Carolina shiner, a cute little minnow, when a dam was peeled off the river near Carbonton, N.C., as seen in the photo.
