A comprehensive global assessment reports that if the current rate of marine ecosystem degradation continues, the collapse of commercial fish stocks and coastal ecosystems could reduce global aquaculture and wild-capture yields by 15% by 2040. Furthermore, if key marine tipping points are crossed, the loss of natural coastal defenses and reef-based tourism is projected to trigger a cumulative reduction in global real GDP of up to 18% by 2080.
Evaluate the potential trade-offs and synergies between policies designed to achieve marine and environmental sustainability and the pursuit of other macroeconomic objectives.
