The state of the ocean
The ocean has been severely impacted by pollution, overfishing, and climate change. Carbon dioxide emissions have led to acidification and warming of the ocean, affecting marine life. Overfishing has depleted fish populations, and coastal development has destroyed important habitats. Plastic pollution is a significant problem, with one ton of plastic entering the ocean every four seconds. Beach cleanups help raise awareness, but the focus should be on preventing the flow of plastic into the ocean and implementing sustainable practices. While technology for ocean cleanup is promising, preventing plastic from entering the ocean in the first place is a more effective approach.
