I hate the "gallons of water are used" statistics because water is a completely renewable resource if managed properly, and mostly it's managed properly these days since we realized it was a problem if we didn't.
What exactly do you plan to use the extra water for if we stop using it for beef? Most if it is used to water the feed crops that cows eat, so what do you plan to use those farms for instead?
Is there a plant that grows in those same areas that's currently too expensive because of a lack of land? Most of the expensive fruits/vegetables these days are expensive because of the labour involved in harvesting/processing them not due to a lack of cheaper land.
I think they fundamentally misunderstand. There's no way that they're claiming you can raise a herd of cattle or any animal without ever giving them access to water.
Support, sure, but if you choose to take a job that requires employer supplied food you really shouldn't be surprised when they don't serve your custom menu. The employer probably provides two or three different options each meal to satisfy basic allergy/food preferences and that's a reasonable accommodation.
What if I started a diet that only allowed me to eat wagyu beef garnished with saffron twice a week? Would they have to pay $400 a day to feed me as long as I could prove I eat that for "creed" reasons?
"Nothing fancy at all" What's the legal definition between fancy or not?
It costs more money to hire people to cook an entirely different meal. It costs more money to buy small quantities of different foods. It costs more money to import fresh products into forest fire zones. Some vegans won't even eat from plates/cups/cutlery/pans/chopping boards that have had animal products touch them. That would add even more cost.
Should there be a dollar limit on what is considered fancy?
In Canada, even for protected classes, you're only entitled to reasonable accommodations by employers. For example if you're blind (a medical condition is a protected class) a taxi company doesn't have to hire and accommodate you. If you're deaf, a call center doesn't have to provide you with a sign language translator who listens to your customers.
