Sobering assessment of global wilderness areas

As an addendum to the previous post, an assessment of global wilderness came out today as a comment in Nature: https://www.nature.com/articles/d41586-018-07183-6 . Authored by Watson et al., the assessment concludes that (at a 1km resolution w/ a minimum patch size of 10,000 km2) 77% of the earths surface is impacted by humans. The authors specifically call out carbon valuation as a way to potentially justify saving the remaining few areas to skeptics.

The coast of Alaska is one example of some remaining wilderness, or recovering wilderness (in the logged regions). It’s immense carbon stocks are but one aspect of it’s value - perhaps not even the most important part, the wildness which is less substantial but more significant.
