I agree, of course, that we must take costs into accounts. Comments by meh basically explain how to think about that.
You said, in what I consider an unjustified mocking tone, that my dietary choice was "not particularly" effective in reducing my carbon footprint. This is wrong.
For the record, I never claimed, implied, or believed, it was the most efficient thing for every single person concerned about global warming to do. I believe my writing is very clear. I feel you are being an uncharitable discussion partner. At this rate, I will not continue discussing the issue with you.
I feel you misinterpreted my tone.

Here are some questions that come to mind:
