    Mitigation shortfalls in mining

    Sustainable mining relies on vigorous and comprehensive mitigation strategies; however, two studies in this issue show that these measures are falling short. Among artisanal and often illegal mining operations in the Amazon, Fritz et al. demonstrate that while mercury retorts reduce losses, the amount of mercury and CO2 emissions into the environment remains substantial. Globally, Aska et al. draw attention to the number of mine tailing facilities contained within or near the boundaries of protected areas, posing a potential hazard for regional biodiversity.
