If you don't have a car and rarely eat red meat, you are doing GREAT ๐๐ ๐
Sure, you can drink tap water instead of plastic water. You can switch to Tea. You can travel by train. You can use Linux instead of Windows AI's crap. Those are great ideas. But, don't drive yourself crazy. If you are only an ordinary citizen, remember that perfect is the enemy of good.
I do green peppers and asparagus, green but not so much leafy lol, along with a sweet onion. Meal prep that stuff on Sunday and my lunches for the week are all taken care of. It's like one of the few areas of my life I feel like I'm doing pretty well in.
