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 not to quibble with your dietary choices but no single trip from a private flight is producing 47kt of CO2. A fully loaded 737 is like 80t and only about a quarter of that is fuel.

47kt is about half the weight of a Nimitz-class nuclear aircraft carrier, or 8 Arleigh Burke guided missile destroyers fully loaded.

@phenidone Sorry, that was a typo. Should have said 47 tons, not kt. Math is based on the actual amount, which I got from here: https://mastodon.social/@elonjet/110769636396874012

I didn't validate the ElonJet number so it may not be right

@phenidone Googling seems to say that 1 kg of jet fuel produces 3.16 kg of CO2, which means that the 13,556 kg burned in that trip, which gives 42,837 kg or just slightly, more than 47 tons.
