Nature Communications A University of Queensland photo. Threats to biodiversity could increase in the future as more mines target materials used for renewable energy production, suggests a study in Nature Communications. Renewable energy production is necessary to mitigate climate change. However, only 17% of current global energy consumption is achieved through renewable energies. Generating the required technologies and infrastructure will lead to an increase in the production of many metals, which may create potential threats for biodiversity. Laura Sonter and colleagues mapped mining areas globally and assessed their coincidence with biodiversity conservation sites. The authors found that mining potentially influences approximately 50 million km2 of the Earth’s land surface with 82% of mining areas targeting materials used in renewable energy production. When looking at the spatial overlap between mining areas and conservation sites, they found that 8% of mining areas c
