A couple of meetings this last week made me go back to work I was involved in a few years ago and revisit the basic ideas. We are well used to thinking about running out of oil – there have been articles and books written about it for at least 30 years now. We are getting used to the idea that we are running out of the capacity of our atmosphere to absorb different gases and not change its properties. The one we mostly don’t think too much about is running out of the stuff that makes up our planet.
