Bogard builds on his argument by explaining that everyday we get 6% more light which is stopping our darkness. We need our natural darkness to help with the night and preserve our energy. He said that every night over 80% of our cities/ towns are lit up. This is a problem because we already have light pollution and it is within our ability to solve it but he says how can we if we get 6% more everyday.

He then realizes that we can not live without darkness so he studies how the cities are all lit up at night and hoe thousands of people
