The meat and dairy industries have lobbied hard for ag-gag laws criminalizing photography on their farms after abuses have been discovered by undercover investigators and activists.
and that's bad
but it's still not necessary to kick cattle for milk
artificial insemination isn't torture. cows aren't kept constantly pregnant. kicking and beating cows isn't part of husbandry. killing cows at the end of their useful life is fine.
We could guillotine all of the CEOs, and revoke every corporate charter, but it'd do jack for the environment, unless unless we also all change our lifestyle.
without those companies, the lifestyles would necessarily change.
you're not accounting for availability of convenient calories. it's cheaper to stop at Burger King than to buy beans and spend my time soaking and cooking. the availability of similarly priced convenient calories simply isn't there if you insist on avoiding animal products.
further, even when people are preparing their own food, if they raise their own, or hunt, fish or trap it, or if it's subsidized or free, then throwing away those foods to buy beans is more expensive than eating what they have.
your characterization is irrelevant to the truth of what I've said.
