Environmental songs played on Window of Opportunity

Following my encounter with Earthgauge, on the CKCU Thursday Special Blend, I was motivated to see if there was anything I should be doing to offset global warming, in addition to personal habits (turning off lights, etc).

I addressed my listeners on Window of Opportunity, our Friday afternoon folkish show on CKCU 93.1 (Ottawa) and challenged those songwriters among them to get to work writing protest songs against the excesses of today's society in its headlong rush to damage the planet. Here are some of the songs that are out there: Environment songs 1  Environment Songs 2  Environment songs 3.
I also decided to play an environmental song each week that I host the program.
