How could I change the world with computer science?

I would program a computer to send out a beam that would pick up all the trash and send it hurtling towards the sun. So the beam wouldn't just fling random people or plastic into the sun everyone's trash would be put in a bin that the computer would sense. This would help reduce the amount of trash there is going into landfills and into the ocean, hopefully. I could program this computer to do this because of the YWIC camp I go to. Today we started making our own company and it was so much fun though I don't think I'm as good at is as the girls around me but I know that if I need any help I can ask the camp staff or my friends.
