Is that from a personal view or a view that everyone should eat less meat, or is he on a diet.
Ok if people do cut their read meat intake or are they just going to eat more white meat ?
Well what is going to fill that void, all become vegan, well that food doesn't grow by itself either. A lot more vegetables grown require more water, more intense farming, more tractor work, fertiliser spreading, more packaging and so.
So to get rid of a few natural farting cows eating natural grass we move into intensive farming to cut back on CO2.
Albo you are a real forward thinker, no wonder you said 2050 as you won't be here to see the kaos created.
