This is our world today:
Millions of human beings take this sort of thing for granted. Vast cities filled to overflowing with millions of people.
Towering high-rises. Jam packed street full of cars, trucks, buses and pedestrians. An endless supply of electricity. Glittering light lighting up the night.
We’ve come to believe that these are some of the things define our civilization. The teeming masses of humanity, piled on top of one another, living in tower after tower of glass, steel and cement.
