Answer:
Space junk can damage satellites and can be lethal to astronauts.
Explanation:
Most of the object considered space waste are very small and travel around the Earth at high speed. Because of this, they can be dangerous for launch vehicles, satellites, the International Space Station and any manned mission should they collide with a spaceship.
The plan proposed by Roosegaarde to reduce space junk starts with a public awareness program that helps inform the public about the reality of space junk.
The eventual plan to end the space waste problem is to upcycle the debris floating around the planet. I think with the use of new technologies it will certainly be possible to eventually eliminate space waste.
