Episode 31 of Books and Ideas is an interview with NASA physicist Les Johnson, PhD. We talked about his new book Paradise Regained: The Regreening of Earth. Although Dr. Johnson is a lifelong fan of science fiction he challenges the common assumption that eventually we will pollute or damage the earth so badly that humans will be forced to move to outer space. Instead, Dr. Johnson argues that we should develop the technology to get resources from outer space so that we can preserve the Earth for Life.
