Only Human Lyrics

Cover art for Only Human lyrics by Jason Mraz

This song is about the Green Movement. Read the lyrics again, and notice "if that's our only excuse, how do we think we'll keep on being only human." He talks about how this (the environment/planet) will outlive him, and makes references to "paving over paradise" and "planets talking about a revolution, the natural laws ain't got no constitution."

It's his commentary (with LOTS of metaphors and word play) about caring for the environment.
