Question

why should we use every City carefully and only when needed​

Answer 1

Answer:

70 percent of the world's population expected to live in cities by 2050, getting urban planning right is crucial to ensuring future cities are safe, resilient and fair places, particularly for the poorest residents, experts said Wednesday.

As Africa urbanizes, its cities will need 700 million more homes, 310,000 more schools and 85,000 additional health centers by 2050, said Christian Benimana, a Rwandan architect.

"How we set up all this infrastructure has to be carefully thought through," said Benimana, who works with MASS Design Group, which focuses on architecture that promotes human dignity.
