We need motivation to solve these problems. Therefore, most kids live in cities. And most of those kids live in urban slums of developing countries. You are shaping the playgrounds of the next generation. You shape the caves that mankind will live and work in.
Cities have long lives.
They consume energy and raw materials and thus, they cause environmental problems. Therefore, architects and designers have to think about the resources they use to build things.
