Happy or sad when more than 70% of the world's population will live in cities?

With dizzying migration speed, by 2050, cities in the world will have to contain more than 70% of the global population. In particular, urban areas in Asia and Africa are the most impacted places.

The world is over 7.2 billion people, about 4.2 billion are living in cities. According to statistics from the United Nations (UN), within 30 years, it is expected that cities will receive another 2.5 billion people. At that time, the number of people in the city would account for 70% of the population.

But is this news good or sad? According to Rober Muggah - director of the Igarape Academy (Brazil), the answer is later, sad.

Currently, there are about 4.2 billion living in cities.

"In the short term, the migration boom will create a worrying picture for cities," he said.

"Cities are urbanized so fast, while industrialization is not keeping pace" - Muggah worries.

"Currently, most cities do not have enough infrastructure to meet that. Therefore, these cities cannot stand the pressure from the wave of labor immigration. In particular, cities The fastest growing city may be the hardest hit ".

In the future, the city will appear to be scary.

Impact of urbanization

According to the UN, by 2030, the world will have 43 megacities with a population of over 10 million people. New Delhi (India) is expected to soon "usurp" Tokyo, becoming the world's largest city, with a population of over 43.3 million by 2035.

Meanwhile, the population in rural areas tends to decrease. It is estimated that by 2050, there will be only about 3.5 billion people living in rural areas.

In the face of this tremendous urbanization, the UN must warn that this trend will create urgent problems for cities. For example, housing, health care, resource and energy exploitation, and education needs .

The trend of urbanization will create urgent problems for cities.

"The important issue when it comes to sustainable development is that there must be a rational and effective city and city management mechanism. This is a difficult problem for low and middle income countries, where there is speed. Urbanization is expected to be the fastest ".

How to live happily in an overcrowded city?

It is often said that the city is a place of intersection and convergence of diverse and rich cultures. However, in the face of the impact of urbanization, these values ​​can be seriously "eroded" .

A recent study by the University of British Columbia (Canada) indicates that many people feel happier living in rural and small towns. The author John F. Helliwell shared that the factors affecting their perception are simple transportation systems, less expensive housing, friendly, close neighbors and a clean environment.

These are all things that cities are losing.

When there are too many people, the quality of everything seems small.

It can be realized that the biggest impact of urbanization is that the city is losing its connection with nature. Instead of skyscrapers, vehicles increase exponentially.

"We found that like other drugs, nature is the best spiritual medicine, " said freelance journalist Florence Williams.

In other words, when you have to live in a city that is too crowded, too modern, find ways to get closer to nature. You can grow plants indoors, take a walk on the road with the shade of green trees.

This will help the city reduce the burden somewhat on the mental and emotional needs of the people.
