alt Hacker NewsFor me, it's a hard problem.
For business trips, the choice is between two hours and two days, and unfortunately my body goes haywire if I don't eat some meat at least a couple of days per week (talking about 200g/300g total though. Not kilos of it).
On the other hand, I'd happily take trains as more high speed lines open in my country, and reduce meat consumption to bare minimum my body can tolerate.
For personal transportation, going fully electric won't be possible due to my circumstances, but I'd happily switch to a hybrid which would convert 75% of my in-city travel to electric (which I'm actively planning to do).
I also work on projects which tries to reduce footprint of data centers and computation, so there's that.

Isn't this just a nutrient deficiency in whatever you were eating instead of meat? Meat is "convenient" because it's high in a wide variety of minerals, vitamins, essential amino acids, etc. that your body can't make. (The animals mostly can't make them either but guess what livestock eats.) There are plants that contain each of them, but few if any that contain all of them, and then if you're missing one you're going to have a bad time. So the problem there is almost certainly that you need to eat some different plants than that the thing you were missing is only found in animals.
