If I were a better man, I'd give up fish. I blame the Japanese for creating so many tasting things.

The girl at the supermarket (I say "girl" because she appeared about 12 to my middle-aged eyes even though she was probably 20 and deserves to be called "woman") asked excitedly today if I was a vegan based on cart contents, but I had to tell her alas, no, mostly just shopping for someone with a dairy allergy.

Note that eating the rich and thereby stopping all the private jet and yacht bullshit would blow any other dietary change you could make out of the water.

Since the "Elon Musk's Jet" tracker popped up in my feed, I figured I'd do some quick math. Based on a meat diet releasing roughly 6 kg of carbon per day for a 2000 calories a day diet (from random googling) and Elon's one trip generating 47 kt of CO2.

With this single trip, Musk generated more carbon than a would be saved by a heavy meat eater going vegan for 29 years.

I mean, you probably should eat less meat, but it won't save a planet full of billionaire assholes.

@ucblockhead

You didn't count CH₄ and N₂O. You save a lot more of CH₄ by going #vegan according to that image.

And notice that CH₄ has a GWP (Global Warming Potential) 28x-36x that of CO₂ and N₂O has 265x-298x that of CO₂.

So redo the math and go vegan.

CC @emoryr in case you are open to revise this notion.
