If we cut subsidies and internalized the externalities (i.e. heavy carbon tax on all meat used to offset the GHG emissions), it would be theoretically feasible to make meat carbon neutral.

I'd imagine taking these minimum steps toward environmental sustainability would either a) greatly exacerbate food insecurity in America or b) make meat into a luxury that only the top 10% can afford to eat at all.

Either way, I suppose it would be an effective way to let the market reduce animal agriculture.

If you'd like to help this come about, please consider boycotting the current animal agriculture industry until it reforms, as this kind of carbon-neutral meat currently does not exist.
