Of course meat isn't the only food, but it's delicious and a great source of protein. Sure antibiotics are bad for the system as a whole, but why not go after that instead of boycotting altogether?
Of the people who ski, some would be happy to substitute another winter sport if skiing became less desirable (more expensive or less fashionable). Some would substitute non-winter sports (e.g. go to the California coast instead of Tahoe.)
That's the 'substitute goods' that I mentioned.
If you really love skiing, you're still a part of that economic theory, you're just the inelastic part. You might still substitute something else if skiing became 10x more expensive.
For similar reasons, I’m not interested in going lion hunting for my holidays. It’s harmful. There are other alternatives. So use the alternatives!
Deutsche Bahn helped kick this off by offering some really great combo deals that enticed me to try a different style of ski travel, so how could that be done with food?
