Assessing the economic value of improved protection of the Great Barrier Reef (GBR) is important to demonstrate the consequences of loss and to evaluate the public benefits of programs to reduce pressures and address degradation. However, those values are not easy to measure, in part because of the diversity and complexity of the GBR, and because there are very different types of benefits involved. Since 1985, there have been over 40 major studies that have assessed values for these components at the whole GBR level, and many more for components at smaller scales.

Improved management practices and water quality targets were set in the Reef Plan 2013, but with limited success. The causality between water quality degradation, ecosystem health and benefits to society remains poorly understood, questioning the relevance of current water quality targets.

In spite of the presence of cirrhosis and patchy necrosis on liver biopsy, our patient never showed any clinical feature of impaired liver function.
