Mobile phones, TV, data, video conferencing, amateur radio, and military messaging rely upon satellites.

Control electricity transmission and networks that balance demand rely upon satellites.

Space telescopes, space stations, and soon space tourism all require a sustainable space environment that is maintained in order to avoid collisions with space debris.
