you can do it ethically I'd imagine, but most people don't
Yes, but that's mostly because of the air travel. And most people who can afford to jet around the world will never be persuaded to choose otherwise.
Why is air travel so unethical ?
it's very bad for the environment. If you care about the environment and regularly fly, you're an asshole. Doubly so if you complain about other people not caring enough as you do about the environment or argue that plastic straw (or bags or anything) bans are a good idea.
How am I supposed to get to Furnace Fest then? And wouldn't driving there be worse?
you can do whatever you want, if you don't care about the environment or don't mind being a giant hypocrite, it's fine. I don't funking care, but I'm certainly done feeling any guilt about "how I left the planet" or whatever.
For the record I would at least argue the way I vacation is more ethical than what most people do. I only travel somewhere if there's an event there I actually want to attend. I don't go somewhere just go hang out at a tourist hotel....I can have way more fun even doing things at home with the money I'd spend on it!
My parents went to Hawaii in January and by all accounts had an amazing time, but it's not a vacation that I would go on even if invited.
