Nowadays, the housing problem is crucial and pivotal due to overpopulation which has become make people worry since the start of current millenium. There is a tendency in some cities to extend space for human living filling it with houses on the ground to tackle the issue. Other cities have already found the solution for this hurdle: creating high-rise buildings.
Recently, mankind has realized that a humanity faces the threat of overpopulation. Overall, the bith rate of European and some other countries is decreasing, whereas the total number of people is increasing. The human population of some governments such as China and India is rising steadily during the last time. Consequently, the total number of people is immense and now consists of over 8 billion.
Nevertheless, there is a possible solution to tackle the problem. The area of our planet is not infinite and there are places on the Earth which are not habitable for people. There are rivers, oceans, volcanoes, glaciers and other places where a human can not live in the current moment. Thus, extending natural habitat for people is not appropriate idea. In contrast, building high-rise housing estate is a reasonable and modern solution. The atmosphere virtially does not have any barrier and height is more safe zone for human lives.
To conclude, despite the fact, that issue of rising the number of people on the Earth has emerged, a humanity could solve it creating new high houses and expanding the location for human being not on the ground.
