That's because it's an alarmist piece which aren't too difficult to find in The Guardian. They do sell papers after all.
I'm by no means claiming there is no problem and the situation is fabricated; However, using terms like “ecological Armageddon” really makes your amygdala go into overdrive and for what? To shock people into action or something?
Right, but having your species single-handedly cause a mass extinction event on a scale not seen in 250 million years and having it happen in the span of a couple centuries (which is like a millisecond in geological time) seems like a pretty big deal to me. Like the biggest of big deals that we’ve ever lived through. This is a “there is a three mile wide asteroid inbound that will hit the earth in 80 years” kind of big deal.
That seems highly obfuscatory for describing a catastrophic event to a nonscientific audience. Might as well call it an “unplanned existence deficit” or something.
