April 21, 2011 – Hour 1

First, we have this week’s installment of Spotlight on Maryland Housing with Maryland Housing Secretary Raymond Skinner.

Paul Ehrlich has taken the concept of sustainability seriously long before it was a buzzword.  Best known for his 1968 book The Population Bomb, Ehrlich’s work as a biologist, writer, and educator has focused on the tension between population growth and limited resources.  He joins us today to talk about his work, including his new book, Humanity on a Tightrope.

We wrap up the hour with a poem for Earth Day from environmental writer Tom Horton.
