There's plenty of places where one can go and eat ethically killed animals nowadays (locally raised, organic, free range etc)Especially here in southern California where i live.
farmed animals produce about 10% of the world's emissions, many vegetable oils have a bigger footprint than animal fats
With the current trend in technology, : low energy, low waste, just, diverse farming is possible. Vegans are such extremist.
The issue isn't eating meat, it's the current farming model that is the problem in this country.
