Madagascar: Escape to Africa

While the hit sequel about wayward zoo animals is played for laughs by its cast of comedians (Chris Rock, Ben Stiller, David Schwimmer and Sacha Baron Cohen), there’s a minor environmental plot thread with a potentially serious outcome: stranded tourists selfishly dam a river, diverting the water supply and threatening the idyllic ancestral watering hole. The zoo crew saves the day, of course, but not before the movie makes a valid point about preserving nature.
