Historically the earth ocean had a pH of 8.2. In recent years it has dropped to 8.1. How might this change affect the ocean environment?

The decrease in ocean pH from 8.2 to 8.1 indicates increased ocean acidification, primarily due to rising atmospheric CO2 levels. This change can negatively impact marine organisms, particularly those with calcium carbonate shells or skeletons, such as corals and shellfish, making it harder for them to grow and survive. Additionally, altered pH levels can disrupt marine ecosystems and food webs, affecting species diversity and overall ocean health. These changes can have far-reaching consequences for fisheries and human communities relying on marine resources.
