The main reasons I’ve seen from vegans for not eating meat seem to be all about the morality of eating a sentient animal, the practices of the modern meat industry, and the environmental impact of it. And don’t have anything to do with the taste of meat.
Since lab-grown meat doesn’t cause animal suffering, and assuming mass production is environmentally friendly, would you consider going back to eating meat if it were the lab-grown kind?
Greenhouses aren’t lit, usually. What are you talking about?
Depends on where you live. The further north you go, the less sun you have. And most people in developed countries live quite up north.
I was thinking indoor hydroponics. Vertical farming.
Way less water than traditional growing. Like 90% less or something like that, but the LEDs aren’t cheap and use a lot if power. Also a lot less space.
