% Of people in cities

In 2018, 3.5billion people lived in cities, By 2050, that figure will have risen to 6.5 billion people.
Our opinion is that the towns should be restored so that people can live comfortably as in the city. (Kenya G. Spain)

Thinking about this fact, we need to give these people a better place to live, they must have better living conditions. The government could finance these new houses. (Kenya G. Spain)

Cities and communities problems

The cities are very important for the human being, but they make pollution. Furthermore they aren't inclusive and don't have access to green spaces. The cities also don't have money for basic services and a lot of houses are missed. Last of all they have some infrastructure in degradation.(sebastiano It)

The future of urban expansion

If the expansion of cities continue this way it's probable that in the next decades, the 90% of the urban expansion will be in the developed world. We think that the urban expansion not only should focus on developed cities, the undeveloped cities need the governments help to improve his lifestyle. (Juan, Spain)

Back to the field

The population increase in cities has been increasing more and more, so that each person has less space for themselves. So we have to take advantage of space and not be all the people in the cities, and go back a bit to the past, where there were still a lot of people in the fields (Tiago P. Portugal)
