Hopefully not the apocalypse

Summarizing the environmental work to do

Thomas L Friedman’s stimulating book ‘Thank you for being late’ reminds us that the Holocene era, an era of unusual stability, has lasted just the last 11,500 years or roughly the same time we’ve had farms and civilisation.

Can we ourselves disturb this happy Holocene stability? It seems we can. Friedman summarizes eight different ways we may be inducing planetary organ failure, based on work by Rockstrom, Steffen and others in Science on Feb 13 2015:

  • Climate church – already reached Holocene-rocking levels (they claim)
  • Loss of biodiversity -ditto
  • Deforestation – ditto

Then he lists four more that his source considers within safe levels, but only just:

  • Ocean acidification
  • Freshwater use
  • Atmospheric aerosol loading (diesel particulates and whatnot)
  • Introduction of novel entities (plastics, nuclear waste etc)

Finally one example of where we did breach safe levels but are now retreating back to safety: stratospheric ozone.

A useful summary, then, of the big main environmental issues. Human civilisation has only thrived in the Holocene bubble. Will we pop it, a DIY apocalypse?  Or will we seek God for our ‘daily bread’ and manage to preserve our species and our planet for further adventures?
