An increasing level of carbon dioxide in the atmosphere can lead to a phenomenon known as ocean acidification. As carbon dioxide is absorbed by water, it reacts to form carbonic acid, which lowers the pH of the water. This decrease in pH can negatively impact pond ecosystems by disrupting the balance of various species, decreasing biodiversity, and potentially harming important species, such as fish and plants. Additionally, the changing chemistry of the water can also affect nutrient availability and the overall health of the ecosystem.
