Nope.
Why does this question even exist? Do some people actually want our species to go extinct? Animal abuse laws should exist, but going as far as to illegalize a major source of food for humanity is a terrible idea for reasons that need not be explained.
I am a meat lover myself, but humans can easily survive without meat and its more energy efficient to eat the plants yourself than having them processed by an animal which you then eat. So in terms of avoiding food shortage we should all go vegetarian.
