The article discusses the impact of climate change on marine ecosystems, focusing on the alarming increase in ocean acidification due to the absorption of carbon dioxide by seawater. The changing chemistry of the oceans is threatening the survival of various marine species, such as coral reefs and shellfish, as well as disrupting food chains and ecosystems. The consequences of ocean acidification extend beyond the marine environment, affecting human communities that rely on seafood for sustenance and economic livelihoods. Urgent action is needed to reduce carbon emissions and mitigate the effects of climate change on our oceans. By raising awareness and implementing sustainable practices, we can work towards protecting marine ecosystems and ensuring a healthy future for both marine life and human society.
