Turns out that what's sustainable is often what is vegan. Vegans are constantly discussing the edges of all this stuff trying to come to a better understanding, its somewhat natural that they would provide some of the most well-reasoned and substantiated arguments.

Honey and tilapia are not sustainable currently. Its a demand issue. Rules and regulations will never prevent an industry from meeting demand. Thats why we currently use practices at large scale we never would at small scale.
