Agriculture can prove extremely difficult to maintain on a rocky mountain and with such poor infrastructure it is also difficult to import goods on a JIT (Just In Time) sort of basis where you receive these goods as you need them. Infrastructure also includes communication and other services and with such a technologically developed era we depend on technology and this can deter a lot of people from settling in these regions, additionally the wildlife in these regions consists greatly of predators which can be deemed a threat to habitants who are unprepared. The sheer abundance of wildlife and non industrial landscapes can also mean that people will not want to live in these regions
