Earth’s Primary Life Support System … And Why It’s Important To Understand How Humans Are Changing It
Net Primary Production (NPP) is the term used for the amount of biomass stored when plants take in carbon dioxide (CO2) and water that they don’t subsequently release. And this Net Primary Production is the building block for nearly all ecosystems on earth – it provides us with everything we eat. In Episode 9 of Crucial FEWSION we hear about the latest research on how Humans Appropriate that Net Primary Production, called HANPP for short, from researchers Suman Paudel, Kaeli Mueller, and Assistant Professor Gustavo Ovando Montejo, all lead by Professor Christopher Lant at Utah State University. So, get ready for some staggering planetary statistics as we explore HANPP, its history … and why what happens to it in the future is so important.
