Why is the “asphalt” desert (a world without wildlife) unsuitable for human life?

The “asphalt desert” is not suitable for human life because clean and fresh air, clean water, organic food, and a positive psychological climate are needed for a normal life. And the asphalt, which is abundant in cities, increases the air temperature, makes it dry, does not please the eye – it oppresses, there is not enough oxygen in the air, the plants are dusty and therefore photosynthesis is not efficient enough, and there are few plants themselves in cities, they do not have time to cope with harmful , for example, from transport.
