As far as I'm concerned, this is the only argument for vegetarianism I'm interested in. It is a very good one, and I recommend giving it consideration. I, personally, try to have vegetarian lunches, or vegetarian dinner if I had meat at lunch.

I have no desire to stop eating meat entirely, but I think moderation can have a massive impact. We should all share the costs of climate change, and going without chicken on that Caeser salad should be right at the top of the list. Interestingly, this is exactly the opposite situation for me when it comes to alcohol, but the same result - I have no real desire to drink (and would happily go completely straight edge) but do so in moderation in social situations where, quite frankly, it's almost seen as offensive not to (happily, I've learned how to have a drink in hand and remain sober). I wish I could always have Coke, but I also wish to avoid unnecessary dramas.

By the way, I don't count fish in this (neither as a food nor as an alcoholic drink). They don't live on land, we don't cut down rainforests to build aquariums. Although that would be more pleasant.
