We rely on space for a ton of things. It helps our technology work properly. If something happened in space that could mess up our technology. The world would practically be paused and be chaotic with us relying on traffic lights, credit cards, and GPS. Us having all our things done through space could lead us having a space war. There is a space organization in the Air Force branch of the US military that watches and makes sure nothing like that is going to mess anything up. I think its a good thing we have a group like that because what would we do if we were cyber hacked or something?.
