No, just informed and non destructive tourism. The number of tourists coming to berlin, for example, doubled in 10 years, the infrastructure almost didn't change in the same time. 3.5 million inhabitants, 14[0] millions annual tourists. Every single month of the year: 40%+ of the population is made of tourists.
