It's interesting to note that people tend to move to country to get away from the city, then turn around and try to bring many parts of the city with them. Not only that, but once they are out in the country in their brand new location and often brand new house, they begin to decry the influx of other people from the city who build houses and ruin the countryside.
The thing that rankles me personally is that I have a not so old (10 years, maybe) house in the country that I've been trying to sell for 2 years with little luck, yet people are building new houses left and right.
The big thing going on here is that farms are being bought by developers who break them up into 5 acre lots to avoid the rules that apply to smaller pieces of ground. This ends up putting 20 homes on land that could hold 50 or more on smaller lots, leaving the other 30 looking for their own 5 acre plots and eager to destroy more farmland to get it.
It's an ongoing problem with no easy answer. While it's better for the land to have people live in dense clusters, it's better for the people to have more personal space around them.
Just to add fuel to your fires, if you guys check the statistics you will find that any residential development, even one house, costs the surrounding community more in services than it provides in taxes. The imbalance varies from place to place, but it averages about 30%.
