>>Any unnecessary and polluting economic activity that is actively killing the planet, yes. All economic activity pollutes, and therefore according to your logic, is "actively killing the planet". And if you want to be Spartan about it, a significant portion of economic activity is unnecessary, so your criticism is equally applicable to a major share of everything humans do. In reality people need more than the basic necessities, and will pursue more than them. You're not offering a reasonable way forward with your over-critical analysis that singles out tourism as a harmful activity because of a particular set of properties that it has, that are shared by numerous other activities.
