"seasonal", "domestic", and "regional"
Yeah most of the produce in the grocery stores are from France with only a few exceptions. But even with the exceptions there is always a France option as well. It also helps that they have a very long growing season. Even in the winter there are crops being grown - usually hearty crops like Kale or something.
Yeah I hate to even think about the conditions that animals that we eat live in. I essentially swore off meat for about two years after first learning about how the animals were raided and all that. But I have since begun to eat meat again. For me it is hard to stay a vegetarian long term. Tbh I'm actually looking forward to when cultured meat becomes economical.
You are right that it is the consumer that drives the markets.
