climate change: Increases water temperature, it causes polar ice melt and alters ocean currents. This affects marine life, especially corals, which suffer bleaching and death. Plastic pollution: Millions of tons of plastic end up in the oceans each year. This not only affects natural beauty, but also endangers marine life, as marine animals can mistake plastics for food. Overfishing: Overexploitation of fish resources depletes fish populations, altering the balance of marine ecosystems and affecting human communities that depend on them. Ocean acidification: As the oceans absorb more carbon dioxide (CO₂) from the atmosphere, become more acidic, which particularly affects organisms such as corals, mollusks and certain types of plankton. Habitat destruction: Coastal construction, marine mining and other human activities destroy critical habitats, such as coral reefs, mangroves and seagrass meadows.
