I've mostly seen statistics about water usage for dairy milk production, but it takes a lot of water and food to raise a cow to maturity. Fish (if harvested sustainably) care for themselves until caught, so it makes some sense to me that planting, growing, harvesting, and processing soybeans into tofu would have similar impact to fleets of ships traveling the ocean catching fish.
A few years ago I read and enjoyed the book "The Omnivore's Dilemma" by Michael Pollan. The author follows three different meals from farm to table as completely as possible given the nature of modern food production. It's a great read for someone who wants to know more about where food comes from and how it gets here, and it's definitely made me think about what I'm eating.

- drewzero1 5y agoI don't think so, unless there is a significant amount of carbon released due to the way the fish's food grows. It's certainly not the same as running all of the machinery required to process and transport livestock feed. There has been some interesting back-and-forth about the role of the fish themselves as a natural carbon sink[1][2]. I don't pretend to understand the science or math involved in these calculations though.
