Three significant environmental concerns affecting our oceans today are plastic pollution, ocean acidification, and overfishing. Plastic pollution primarily arises from inadequate waste management and excessive single-use plastics, leading to harmful debris in marine ecosystems. Ocean acidification is driven by increased carbon dioxide emissions, which dissolve in seawater and lower its pH, adversely impacting marine life, particularly coral reefs. Overfishing results from unsustainable fishing practices and high demand for seafood, depleting fish populations and disrupting marine food webs.
