This week, the first film based on the blockbuster young-adult book trilogy The Hunger Games will open, crowning its stars heartthrobs and, likely, making Lionsgate, its studio, a mint.
Much discussion has focused on The Hunger Games as commentary on the popularity of reality television; actress Jennifer Lawrence, who stars as the temperamental heroine Katniss Everdeen, said as much in a recent interview. But barely mentioned in the film—if at all—is another, subtler lesson currently in vogue among young-adult fiction: the societal implications of climate change.
