Man is not killing earth, man is killing man and there will be casualties along the way, but earth will continue without man. Species go extinct all the time, and homo sapiens shall join the list in turn.
I straight up started to taste grass when drinking milk. Then later I realized how bland meat is. I can cook much more flavor and texture into a plant based meal than ever achievable with traditional animal products. Low sodium,cholesterol free, etc etc.
Iirc beef tasted similarly “grassy”. Essentially my tastebuds changed. Food suddenly had different tastes than I remembered. Could be age changing my taste buds, could be focusing my diet on healthier choices changed my tastebuds, etc.
Its common for people who closely monitor their salt intake to be unable to eat many packaged food items - as they suddenly taste all the added salt.

That's a bit of a strange way to put the comparison, as non-vegan meals can include all of those plant based options (just with meat in addition to them). And whether you like meat flavour and texture or not, there is a lot of unique variety in meat flavour and texture that's distinct from what's in plant-based options.
