> Degradation of soil - or specifically - the ability of topsoil to retain enough nutrients to support agriculture - is not the primary problem we are facing today. I agree. The biggest problem is our culture taking an overly simplistic reductionistic approach to create solutions (aka the silver bullet). There are a number of issues that all need to be addressed. That being said, Degradation of soil is a major issue that needs to be addressed; if it's not addressed, we will have compounding issues. Note that 12 million hecacres of arable land is lost every year from desertification, caused by soil degradation. http://www.un.org/en/events/desertificationday/background.shtml http://www.un.org/en/events/desertificationday/background.sh...
