Global Resource Observatory
The project is looking to map the worlds resources and test the system for fragility.
If you want to worry about anything, then it is POLITICS that you should care about!
It turns out that we now have a finely tuned world. Like any system close to optimum, it is sensitive to perturbations of parameters,with wild swings E.g. Low global rice or wheat yields have resulted in riots.
A major perturbation, such as a trade war between trading blocks, can make the whole thing collapse.
E.g Europe is dependent on Russian gas, China is dependent on imported protein, etc etc.
While a big earthquake or Volcano are non zero risks, the big risks are idiot politicians!
