In addition environmental problems like air pollution and waste pollution are coursed by the big amount of people living in a city.
Therefore it is important to think about sustainable methods to act against these problems. Especially us, the young people and the youth of the society should be aware of the problems that are already existing and be cautious of the upcoming problems in the near future.
There are already visions and projects that we can take as an example to be visionary and make the world a better place. Vertical farming and urban gardening are examples for this sustainable development.
Probably the growth of cities and urban areas will continue in the future and it is not unrealistic that in the end of this century, nearly every person in the world will live in an urban area.
That’s why the World Cities Day is a really good opportunity to make people aware of the current and future development of the global situation.
