Nature tourism needs to be scaled horizontally. There are plenty of beautiful places to go, just not everyone can go to the same few places.
Landscape of Hawaii will be more popular than Nebraska, unless maybe 90% of the world looked like Hawaii and 10% like Nebraska.
Fuck no. Tourism is a vampiric money-making enterprise that absolutely ruins that which it attempts to make accessible.
And of course since we specialize, it's not surprising that this too became something that produces a surplus.
It's up to society and culture as a whole to protect and preserve said wonders. (From park rangers to laws and entrance limits and lotteries.)
Sure, tourism ruins a lot of shit, but tourist dollars have improved the quality of life for millions and millions of people all over the world.
