Canadian Indigenous scholar, writer, activist, poet, and artist Leanne Betasamosake Simpson speaks and sings of the urgency of taking care of a planet in peril on her new album 'Theory of Ice'. It is, as PopMatters explains - "a dramatic, deeply eloquent, and musically rich celebration of the Earth and one of its most precious resources: water". Although concerned about the future, Betasamosake believes "human relationships can create real change" and she makes "saving the planet... somehow seem within our grasp".
