How Is Biodiversity Threatened By Increased Ocean Acidity?
How Is Biodiversity Threatened By Increased Ocean Acidity? Normally, phytoplankton near the ocean’s surface take up carbon dioxide and then sink towards the ocean floor. This process lowers surface carbon dioxide concentrations, facilitating its uptake from the atmosphere. But acidification weakens this biological carbon pump. Why are the oceans becoming more acidic? Because of human-driven
