Residents of Greek islands, particularly Santorini and Paros, have raised alarms over 'tourist overload' as the influx of British holidaymakers threatens local culture and sustainability. Nicolas Stephanou, a local advocate for environmental sustainability, warned that over-tourism is causing irreversible damage to the islands' identities and natural resources. Tonia Pantelaiou highlighted the depletion of Paros's beauty and authenticity, citing the strain from luxury developments that consume precious water and energy. In Santorini, Mayor Nikos Zorzos announced a cap on cruise passenger arrivals to 8,000 per day, starting in 2025, in response to chaotic tourism levels that saw over 11,000 cruise passengers in a single day. The local community is divided, with some defending the island's charm while others express frustration over overcrowding and litter. The ongoing situation reflects a broader trend of unsustainable tourism practices in popular destinations across Europe.
