Hollywood isn't afraid to imagine what would happen to planet Earth if a disaster struck.
Over the years, we've watched ice caps melt, a country suffer an oil shortage and animated animals fight for survival on the big screen.
From Madagascar: Escape 2 Africa to The Day After Tomorrow to The Day the Earth Stood Still, we've received a strong message at what could happen if an eco-disaster hits.
In honor of NBCU Earth Week, we've compiled the best eco-disaster flicks sure to get you thinking twice about how you treat the place we all call home.
