John, I agree with you that the biggest problem is the population of humans-- and that’s why I think a huge decrease in meat consumption is necessary for a more sustainable food system. I agree and understand that manure can be used as fertilizer-- but the manure from CAFOs (the vast majority of where meat comes from) is not (or shouldn’t be because it’s toxic). This drone footage shows a pool of animal manure and urine the size of 4 football fields: https://youtu.be/ayGJ1YSfDXs (you don’t have to listen to the guy talk, just look). There’s no way that is healthy for the community in that area.

I think (and hope) that from an environmental standpoint, the meat industry CAN be sustainable — but it isn’t. I don’t think it could be at the rate at which the US in particular consumes meat. As far as water, I don’t agree that we can compare the water use of animal agriculture to plant agriculture — It’s just not comparable. There are numerous studies showing the amount of water needed for a pound of various types of meat versus plant food. And the process cleaning that water for human use should not be taken lightly.

I appreciate your response as someone in the industry, thank you.
