I just had a Mcdonald's double cheese burger. But this reminds me of something I've read a while ago. For about the same amount of calories it takes to continually maintain one cow from birth to slaughter, you can feed 50 times the same amount of people - that the cow's meat would provide. Theoretically, Earth can support about 40 billion people if we were to switch over to veggies and insects. Just a thought.
