I think one of future potential threats that in many cases is already happening, is the shortage of clean drinking water. It is either the land is becoming too arid, fresh waters contaminated by salt due to rising sea levels ( already been seen on the small islands throughout the globe ), toxic pollution from Industry/farming etc, acidic rain, privatization, legal restrictions on rain water collection. Corporate/bank etc buying up land above aquifers just to name a few.....
