Horizon

SYNOPSIS

Part two of two. Every year roughly 65 billion animals are slaughtered globally for food - nine for every living person. In this documentary, Michael Mosley examines the impact this is having on the planet and finds out what meat we should be buying if we want to be eco-friendly carnivores. Is it better to purchase free-range organic or factory-farmed options? The answers are far from obvious.
