Who Killed the Colorado River?

From its source high in the snowy Rocky Mountains, the Colorado River runs through two countries and five states on its way to the Gulf of California. Or at least it used to. The river hasn’t met the sea in decades. All that water disappeared into a complicated web of poor management, short-sighted policies, and human infrastructure, as this video from PBS Terra explores. Unfortunately, while the details vary, this story is not unique, and many rivers around the world are no longer completing their journey. The good news is that we can still change that and rehabilitate the landscapes we’ve lost. (Video and image credit: PBS Terra)
