This extinction warning just doesn’t add up

Anyone watching the BBC’s News at Ten on Monday would have been surprised to learn that economic growth poses a dire threat to the future of life on this planet. We’re used to hearing this from climate change campaigners, but I’ve always taken such claims with a pinch of salt, suspecting that the anti-capitalist left is distorting the evidence. Apparently not. ‘One million species at risk of imminent extinction according to a major UN report,’ intoned the BBC. ‘It says the Earth’s ecosystems are being destroyed by the relentless pursuit of economic growth.’ So does this mean the Extinction Rebellion protestors are right?

I decided to do some digging to see if one million species really do ‘face extinction in the next few decades’, as the BBC put it. That claim is based on a report by the UN’s Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), but it hasn’t been published yet.
