the toll of eating meat on environment is far greater than your concerns over your feelings. choose the lesser evil
If human population drops to zero due to climate change (which meat consumption contributes to), then the environment will be left alone and do great on its own! It wont even take more than 1-2 millennia for recovery, which is nothing in geological terms!
Compared to that eating vegan is just a feel-good half-measure.
I see the point. I don't think it's the answer most of us prefer though.
