For millennia we have had the same reasons for avoiding meat:
- Compassion for the animals, particularly avoiding factory farms.
- Expense. Animal feed and meat are heavily subsidised.
- Health. Animal-based diet tends to clog the arteries and put on fat.
Today, we have a new, much more important reason to avoid meat — 18% of greenhouse gas emissions are generated as a side effect of raising meat.~ Roedy (1948-02-04 age:69)
