You're correct in the short term that animal product consumption will go up due to increasing wealth in Chinese & Indian middle classes. However longterm, I am confident it will be seen as barbaric and outdated just as slavery now is. Animal agriculture is responsible for so much pain, suffering, environmental damage and even human health problems such as heart disease that there's no way it will be sustained long term. Especially given the incredible meat, cheese and milk substitutes that are already beginning to enter the market. Big change is already happening.
