acidification

Acidification refers to the process where the pH level of an environment decreases, making it more acidic. This often occurs when carbon dioxide (CO₂) from the atmosphere dissolves in water, forming carbonic acid. In oceans, increased CO₂ from human activities like burning fossil fuels has led to higher acidity, which can harm marine life such as corals and shellfish by dissolving calcium carbonate structures. Acidification can disrupt ecosystems, affect species survival, and impact industries relying on marine resources. It is a significant environmental concern linked to climate change and carbon emissions.
