Developments in farm technology mean that farms can produce more food with less labour than before. At the same time, prices for farm produce have been kept low, although in most countries supplemented with government grants, so that it takes more production to support one farmer. As a result, farms get bigger and bigger and there are fewer and fewer people farming. As people leave the rural areas, there are not enough left to justify services such as retail trade, schools, hospitals and recreation. As a result, in the smallest communities, these services close, the communities die, and the declining rural population is forced to travel further and further to get those services, until all of the communities outside of cities are closed down.
