Plans for a new Guggenheim Museum in Guernica and the Urdaibai biosphere reserve in Spain have sparked controversy. Supporters believe it could boost the local economy and culture, while critics, including Greenpeace, warn of environmental damage and insufficient public consultation. The project aims to attract 140,000 visitors annually, raising concerns about its impact on the local ecosystem. Basque officials assert that public consultations will take place and that the project will consider environmental protections.
