In my first publication on sargasso algae, I argue that tourism along the coasts of the Mexican Carribean must be understood as enabling both environmental problems and environmental protection. Multiple ambivalent effects of coastal tourism emerge as a result in the Anthropocene. My article is open access – thanks to Goethe University for funding my research – and can be found here with Coastal Studies & Society. https://journals.sagepub.com/doi/full/10.1177/26349817221132379
