The most important issues facing the world’s oceans today include pollution, overfishing, and climate change. These factors have led to a decrease in biodiversity and an increase in ocean acidification. Additionally, plastic pollution is becoming an increasingly serious problem for marine life and people who rely on the ocean for their livelihoods. Finally, rising sea levels due to climate change threaten coastal communities around the world.
