Secondary.

Secondary delves into the contrasting aspects of Brittany, where the region's rugged coastlines, textures and rich history are juxtaposed with the growing environmental threat of green algae blooms, known as "green tides" (marées vertes). These tides result from agricultural runoff and wastewater discharge, leading to oxygen depletion, marine life damage, and toxic gas emissions, which can be fatal.

Secondary also aims to highlight the social and economic issues exacerbated by the proliferation of secondary and tourist homes near the coast, particularly in areas like the islands, Morbihan, and Finistère, where up to 50% of houses are left vacant, turning villages into ghost towns.
