Coral restoration is likely to continue to fail even at small scales unless climate change and other anthropogenic impacts are urgently reduced, according to a review by Australian scientists. They say legislation and policy must concentrate on bolstering ecosystem resilience by reducing greenhouse gas emissions and other drivers of reef degradation. They say some small coral restoration projects may be feasible, affordable, and ethical for areas less than 1 km² that have high economic value, such as tourist sites, but more ambitious outcomes remain elusive and may even be counter-productive.
