There is an urgent need for a new paradigm that integrates the continued development of human societies and the maintenance of the Earth system (ES) in a resilient and accommodating state. The planetary boundary (PB) framework contributes to such a paradigm by providing a science-based analysis of the risk that human perturbations will destabilize the ES at the planetary scale.
~ Steffen, et al.
With the threat of climate change possibly sending us back into the stone age (pre-iPhone), I was curious what real science had to say about human existence. It turns out that all kinds of scientists have been looking into the issue and they have defined ‘planetary boundaries’ that, if violated, run the risk of destabilizing the Earth’s systems.
These global systems have been relatively stable since the Halocene Epoch, roughly the last 12,000 years (or ‘Recent’ according to some geologists), and have allowed modern human civilization…
