We’ve blown past the safe and just limit for vital Earth systems, from climate change to the biosphere and the use of fertilisers and freshwater. For humans to thrive means living in safe limits
Human civilisation is headed for collapse. Collectively, we are pushing planet Earth beyond the limits of endurance. There has to be a better way. Now a new book makes the case for systemic change.
There’s more to sustainability than net zero. Using green ammonia for fuel and as a way to transport hydrogen could add to nitrogen pollution that already exceeds safe planetary boundaries.
Mountaineer and scientist Will Steffen said climbing was similar to science: “That’s the buzz you get in science when you solve a big problem and suddenly see how it all fits together”
