Resource extraction responsible for half world’s carbon emissions

General - Guardian - Key Takeaway: *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, which was released in Nairobi on Tuesday.


Each year, the world consumes more than 92b tonnes of materials – biomass (mostly food), metals, fossil fuels and minerals – and this figure is growing at the rate of 3.2% per year.


Since 1970, extraction of of fossil fuels (coal, oil and gas) has increased from 6bn tonnes to 15bn tonnes, metals have risen by 2.7% a year, other minerals (particularly sand and gravel for concrete) have surged nearly fivefold from 9bn to 44bn tonnes, and biomass harvests have gone up from 9bn to 24bn tonnes.*
