Develop your opinion about build new homes in countryside. General growth of population is one of the major current issues in our world. Due to the increase of population, we have to face new threats, which often cause environmental problems. The main point of concern is up to where we can extend our cities? In this essay I will summarize some causes bound to influx from city-dweller to rural area. Let people who work in city live in the countryside could cause some environmental issues. If countryside is preserve from new buildings more green spaces will still exist. Indeed, places allowed to build rely on availabilities of green spaces. On the other hand, no rational solutions exist to harness global increase of population. Moreover, we can avoid admitting that some huge efforts are brought in construction engineering. More often, environmental impact is took into account construction projects. Although building materials are more friendly environment, construction projects must be thought in respect of environment and carve in ground with less environmental impact. Another cause which can stem from banning new building construction in the countryside is the increase of isolation between people. More cities are overcrowded while countryside are deserted. Amounts of renting or cost of houses touch incredible ceilings in city. Number of homeless increases meaningfully. The border between countryside and cityside has never be so big. It is time to outweigh the border and to learn from one another. To conclude, I am completely convinced that city population could migrate in backcountry. History has proven, isolating people by their origins has never driven to an happy end. This new constructions must be thought in respect of environment and people who live there for decades.
