What are the key problems facing the world’s cities in the 21st century and what can be done about them?
Over the
last
two hundred years, the human population has increased from 500 thousand to 7 billion people. At the beginning of the 20th century, half of all humankind lived in the countryside, but, nowadays, the proportion has changed dramatically, and 90% of humans live in towns and cities

but in small towns too, because their population is also
growing. There is no ultimate solution that can fix all the difficulties of continually growing cities
