Putting a Price on Nature

It's sometimes hard to conceptualise why business and government takes so little serious regard of the level of action that's needed to avoid dangerous climate change. Out of sight, out of mind springs to mind, as this article from the BBC highights. So much of the near term suffering from climate change is already felt by Africa, and this will get worse quickly as water and foot resources are affected. The business dilemma is whether or not to commit 1% of GDP to avoiding environmental and climate degradation. The Tyndall Centre and others say this should be 3%. The BBC article suggests that we risk losing as much as 8% of global GDP. Shouldn't be hard to make the right decision.
