A recent study has unveiled the extensive toll that burning coal, oil, and gas is taking on the world's oceans, revealing the substantial price society is paying for fossil fuel pollution. The damaging impact encompasses a wide array of costs, from dwindling fish populations and disrupted marine ecosystems to the acceleration of ocean acidification and the reduction of oxygen levels. This comprehensive assessment sheds light on the urgent need to address the pervasive pollution stemming from fossil fuel use and to transition toward cleaner and more sustainable energy sources to safeguard the health of our oceans and mitigate the associated societal and environmental costs.
