Theoretically, it could make aviation almost carbon neutral due to inherent inefficiencies, but what good will that do? We need to be heavily carbon negative in order to even have a the tiniest, faintest glimmer of hope to avert our own extinction if we continue to do nothing about this problem.

Reducing consumption is the only way to achieve this but that requires either a monumental shift in human behavior, or simply less humans. And, since we seemingly aren't making the choice, I wonder which one nature will choose for us...

I don't disagree, but the modern world relies on Air Travel and nobody is going to be willing to stop that. We don't yet have energy storage density to a spot where electric flight is "economical". It exists and works well from what I understand but we can't build a passenger jet with it for instance.

You are right though. If we don't make huge shifts then earth is just gonna shed us and recover over a few million years.

It's definitely better than nothing, I'll agree, but also underwhelming from where we need to be because it makes such little difference. Most greenhouse gasses come from factory farming and the activities of corporations. We should still make these baby steps in green technology even if it's too late to change our fate, because the science of it is or could be valuable for an easier, more comfortable, or slower extinction process - as morbid as that sounds.

We can’t afford to just change farming and corporations: we really need to cut carbon emissions everywhere we can. Let’s go for aviation, AND figure out the other industries

We can't afford it? Then we go extinct. What is the higher price? Anyway, it's probably out of our hands by now. Like I mentioned, nature will probably choose for us, and she always takes the path of least resistance.

You missed an important word.

We can’t afford to J U S T ….

Oh, gotcha. The word 'only' instead of 'just' would have made the sentence more clear. Anyway, I wish you happiness and good health!

You can’t just say we need to stop flying: no one will do that, but it’s also not the only choice. If this is a practical way to reduce carbon from aviation, let’s do it. I don’t see anything else likely nor do I see giving up flying.

We need to cut carbon emissions across the board quite seriously, but some industries/technologies will work better than others. Maybe this is all we can do for aviation, but it does help. We’ll just need to make it up elsewhere
