As you'll note, the existing music is non-vocal and guitar driven. The background music we're looking for should convey and symbolize a) the seriousness of environmental issues and b) the contributions each of us can make to mitigate the many problems our planet faces.
A solo instrumental seems to serve the theme that individual action is imperative in the fight to save our planet.
