40 years of Earth Day and we're still clinging for dear life!

For the April 21st show, we celebrated Earth Day by hearing from a Living on Earth podcast about the history of the holiday. We have come a long way from the days of widespread use of DDT and CFCs - but there is no end in site to the battle to protect the planet and its resources.

As for the news...

• Will curiosity kill the feral cat?
• Good dogs live longer.
• What is the most recycled product?
• Geoengineers make a pitch for research funds.

Music featured included: Mirah, American Analog Set, The Arcade Fire, Animal Collective, and Handsome Boy Modeling School.
