Many countries are experiencing population growth and need more houses. Should these new homes be constructed in existing cities or should new towns be built in the countryside.

Nowadays, the demographic growth has been established a challenge for the governments around the world. One of the main issues is associated with the location of the increasing population, which requires a continuous house´s construction as well as new built areas.

For example

services requires a superb infrastructure and a significant intervention in the natural areas.

For instance

In conclusion, the government that requires a houses expansion should develop a risk evaluation in order to pick the best option for the people and the environment.
