In Living Color

Imagine the world as we know it, only without us. In this hour of To the Best of Our Knowledge, a writer imagines a world reinventing itself without human beings. He sees the New York subway system returning to its watery origins. The re-absorption of carbon into the earth, and endangered wildlife coming back from the brink. Also, one man finds the extraordinary in encounters with birds. And, garbage island - the bobbing plastic wasteland that's plaguing the Pacific.
