I agree with your overall statement, but if by environmentally conscious food, you mean vegan, it can easily be cheaper than an omnivore diet. Don’t use any of the meat or cheese substitutes or many highly processed foods, and it will likely be much cheaper (and healthier) than an omnivore diet.
On the other hand, industrial agriculture isn’t very environmentally conscious; it basically turns fossil fuels into food (fossil fuel derived fertilizer, pesticides, and herbicides; machinery, transportation, processing, and refrigeration powered by fossil fuels). Still more efficient than meat and dairy though, since the animals are fed the output from agriculture.
I think EVs are about on par with ICE on total cost of ownership now (but higher initial cost still).
