I can't imagine it not being sustainable, no. Farms that grow all kinds of crops and raise many different kinds animals are sophisticated systems, and humans have learned over centuries how to best utilize them in ways that don't pollute rivers or emit incredible amounts of methane. The reason why they don't work in much of the modern world is because they don't optimize their output for maximum pounds of beef that gets ultimately sold to McDonald's, for example.
