Over 100,000 residents in the Canary Islands and Barcelona protested against the negative effects of mass tourism.

Locals demand government action to limit tourism industry growth by restricting property purchases and introducing an environmental tax.

Uncontrolled tourism has led to higher living costs, overcrowding, and resource strain, contributing to a 36% poverty rate among islanders.

Residents feel the economic benefits of tourism are not reaching them, while they bear the brunt of its impact.

Island officials are considering legislation to regulate short-term rentals, addressing one of the residents' complaints.
