As global temperatures continue to rise, the consequences of ocean warming become more apparent. Tropicalization, driven by these increasing temperatures, underscores the interconnectivity of marine ecosystems beyond geographical borders. Among the most affected are subtropical seagrass meadows, which are particularly susceptible due to their essential role in fostering biodiversity and enhancing coastal defense. Moreover, the ecological shifts prompted by tropicalization are not limited to seagrass habitats but also impact a variety of marine environments and species. The effects on coral reefs and mangrove forests are unmistakable, highlighting the pressing need for immediate measures to counteract the repercussions of ocean warming.
