How does ocean acidification affect marine life?
Ocean acidification can negatively affect marine life, causing organisms' shells and skeletons made from calcium carbonate to dissolve. The more acidic the ocean, the faster the shells dissolve.
Animals that produce calcium carbonate structures have to spend extra energy either repairing their damaged shells or thickening them to survive. Using energy for this could impact the animals' abilities to grow and reproduce.
Animals able to survive and reproduce in more acidic waters are likely to become smaller, potentially affecting the food chain that relies on them.
