But there are also some concerns about building big cities.

The Moscow Times reported that "the main issues include whether the daily needs for food, water and sanitation facilities can be continuously met, and environmental issues."

Mumbai is a good example. According to National Geographic magazine, India's big cities have Dharavi, the largest slum in Asia, with a population of about1000000. It is reported that there are more than 15 people living in one room, and rats can be seen everywhere. A faucet only supplies water for three hours a day, which is used by several families.

In addition, climate change brings additional problems. For example, in 2003, Paris was hit by a heat wave and the death toll soared. The city is not ready for such extreme weather.

So, how to deal with these problems?

According to Xinhua News Agency, controlling the scale of big cities and developing small cities in the surrounding areas may be a solution. For example, in order to alleviate the pressure of environment and population in Beijing, some industries will be transferred to neighboring Hebei Province.

We can also use high technology to help.

The Greentown Project in Masdar City, United Arab Emirates is making a new attempt. This will depend on solar energy and other renewable energy sources. For example, solar air conditioners and driverless electric vehicles will be used to save energy and reduce pollution.

But there are also some concerns about building big cities.

The Moscow Times reported: "The key issues include whether it is possible to continuously meet people's daily needs for food, water and health, as well as environmental issues." .

Mumbai is a good example. According to National Geographic, this big city in India has an Asian slum, Dharavi, where about/kloc-0.0 million people live. It is reported that more than/kloc-0.5 people have to share a room, and there are rats everywhere. A faucet there can only supply water for several families for three hours a day.

Climate change has also brought additional problems. For example, in 2003, Paris experienced a sharp increase in the number of deaths caused by heat waves. The city is unprepared for such extreme weather.

So how can we solve these problems?

According to Xinhua News Agency, controlling the scale of megacities and developing small cities in the surrounding areas may be a solution. For example, in order to alleviate the pressure of environment and population in Beijing, some industries will be transferred to neighboring Hebei Province.

We can also turn to high technology.

Masdar, a green city project in the United Arab Emirates, is trying something new. It will rely on solar energy and other renewable energy sources. For example, it will use solar air conditioners and driverless electric cars to save energy and reduce pollution.
