Extraction industries are responsible for half of the world’s carbon emissions and more than 80% of biodiversity loss, according to the most comprehensive environmental tally undertaken of mining and farming. While this is crucial for food, fuel and minerals, the study by UN Environment warns the increasing material weight of the world’s economies is putting a more dangerous level of stress on the climate and natural life-support systems than previously thought. Resources are being extracted from the planet three times faster than in 1970, even though the population has only doubled in that time, according to the Global Resources Outlook.
