An eye-opening follow-up to the 2008 breakout hit looks at how the food industry has changed, for better and worse

Toward the end of the new documentary Food, Inc 2, the film-makers explore alternatives to the food churned out by the corporate giants doing so much damage to our health and environment.

After meeting people turning plants into “fish” and “chicken wings”, and promising “dairy without a cow” and “honey without bees”, the scene shifts to large steel vats where chicken, pork and beef are grown from cells. This, we are told, might be a future alternative to battery farms and the vast acres of cattle heating up the planet.
