Dr Michael Mosley seeks to establish the truth about meat. Every year, humans raise and eat 65 billion animals - nine animals for every person on the globe. In this eye-opening documentary, Michael examines the impact that this is having on the planet and finds out what meat eco-friendly carnivores should be buying. Is it better to buy free-range organic or factory-farmed meat? The answers are far from obvious. 地平线系列：绿色畜牧由微视影城编辑整理，高清全集完整版持续更新中。如果你喜欢地平线系列：绿色畜牧别忘了推荐wision.net给你的好友！
