If you don’t have a car and rarely eat red meat, you are doing GREAT 🙌🙌 🙌
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.
