A few weeks ago, I wrote about the world's most powerful climate change movement, an alliance of more than 370 major financial services firms representing $41 trillion in green investment assets. This is nothing however, compared to the wealth that an intact environment represents. The Intergovernmental Panel on Climate Change estimates the value of services provided by nature in the form of functioning ecosystems at about $90 trillion. That is roughly the entire current global economic output. A new study by the German Nature Conservation Union and the Boston Consulting Group estimates that the monetary value of biodiversity is twice as high. This does not even include values such as recreation, well-being and enjoyment.
