Why is a man often a danger to mammals that live in the sea?

Humans pose a danger to marine mammals primarily through activities such as overfishing, habitat destruction, and pollution. Fishing practices can lead to bycatch, where non-target species, including marine mammals, are unintentionally caught and killed. Additionally, ocean pollution from plastics and chemicals can harm marine life through ingestion and toxic exposure. Climate change, driven by human actions, also disrupts marine ecosystems, threatening the survival of many species.
