I actually enjoy trying out a variety of vegetarian and vegan foods for this exact reason - just to see how they compare with the meat based ones and how good they are overall. Frankly, it's gotten to the point where most of the food that i buy myself is vegetarian, just because of how many of those options are out there.

That said, it's not a black and white issue, as people sometimes like to view it as - if most people simply treated meat as something to only enjoy rarely (say, once a week or a few times a month) or something for special occasions, then we'd make significant progress in that regard already!

Alternatively, perhaps people should see how their meat is made, or try doing it themselves, to get a greater appreciation for the amount of resources that it takes to produce any (as well as maybe get a bit more empathy towards the animals in some ways). Personally, i've gone hunting with my dad, have gutted animals in the forest, helped bring them home, skin them and cut the bones, all just to enjoy some meat. That's not to say that it'd bear much relevance to the lives of most people, but it's certainly a very humbling experience.

Edit: In the words of Michael Pollan: "Eat food. Not too much. Mostly plants."

I'm actually curious about how others view a more moderate stance on the issue of nutrition - one that calls for gradual changes.
