C'mon. The movie in no way argues a connection between obesity and environmental degradation. The movie shows (1) that the earthly environment was ruined, and (2) 700 years later people are fat. We know nothing about the weight of people before (1), let alone before (2). The inference drawn by this article is simply poor reasoning.

While I'm at it, the conclusions about DNA determining our weight are simply overstated. Obesity increases every year. At some point in American history obesity was uncommon, now its the norm. Does the author mean to suggest that our DNA has changed during this period?
