How would you brainstorm the word "BUILT ENVIRONMENT"?

Think about it, in the enviroment that u live in everything around u pretty much is man made or built by man. There's not really any of the natural enviroment left except some trees and plants and gr. The forests r gone and man keeps downing all of our natural enviroment to build houses, apts., stores etc. So we live in a built enviroment especially if u live in the city!!!
