• To the many comments along the lines of: „But we need food“ – This is actually another great point against Animal Agriculture, as every calory of food produced by Animal Agriculture wastes several calories of feed. https://awellfedworld.org/feed-ratios/
• For people pointing out energy consumption, AI uses ~500 TWH per year, Animal Agriculture uses~ 13000 TWH per year, so it is 25x worse on energy need.
