Nancy Colier argues that smartphones may be replacing human memory and disconnecting us from our physical surroundings and environment. She provides examples of getting lost without remembering directions and relying solely on navigation from a smartphone. Thoreau previously warned about overreliance on clocks replacing awareness of the sun's position. Now, people have little awareness of how time relates to nature. Most people stare at smartphone screens instead of noticing their environment. Relying only on smartphones risks losing a sense of interdependence with the world and others. It is important to notice our surroundings for safety, new experiences, and remembering our connection to the planet and life forms we depend on.
