I echo this- went vegan last year. It’s not as scary as you think. There are lots of sources of good vegetable protein (tofu, peas, beans) and you can have one of those impossible burgers if you’re craving meat on a particular day.
or if you're not up for going cold turkey, just drastically reduce your intake. If you eat meat only once a week rather than every day, this already reduces your footprint massively.
I think that for some people they feel like they are being attacked if someone suggests a change in behavior. It’s not my intention to attack anyone though, just to give words of encouragement. I’m just like everyone else, making it up as I go along.
