Just one hundred years ago tourism was only available to a tiny elite. Like with all goods and services provisions that have been scaled exponentially in the mean time, the problem is that there is poor accounting and management of side-effects (externalities). Impacts on environment and local communities are ignored as it is simpler and more profitable to do so.
Sustainability is a complex problem facing every aspect of modern life that we have barely begun to acklowledge, let alone start really solving. E.g., the article does not discuss the interplay with the other intensive industry of the Canary islands (banana plantations) that also competes for resources and creates its own problems.
It will take major economic, political and behavioral development to transition to long term sustainable economies and its anybody's guess what the final outcome will be.
