Overtourism is choking places like Venice and Barcelona, where locals can't afford rent because short-term rentals dominate the housing market—I saw a report that Airbnb listings grew 40% in my own city in five years. Some argue that tourism brings vital revenue, but does that justify displacing residents and turning neighborhoods into theme parks? I'm torn because my friend runs a successful tour business, yet the streets feel increasingly unwelcoming. Can we find a balance that preserves both local life and the travel economy?
