Watch on Soap2day. Meat the Truth is a high-profile documentary which forms an addendum to earlier films on climate change. Although such films have succeeded in drawing public attention to the issue of global warming, they have repeatedly ignored one of the most important causes of climate change: the intensive livestock production. Meat the Truth draws attention to this by demonstrating that livestock farming generates more greenhouse gas emissions worldwide than all cars, lorries, trains, boats and planes added together.
