Means? Let me attempt to put this into persepctive.
I want you to track down every particle of glass on the surface of the earth. Pick it up, and dispose of it properly, no matter how large or small that glass fragment is.
The proposal you suggest is immense. It include hundreds of millions of tiny particles, along with items the size of a few meters... but spread out over hundreds of thousands of cubic meters of space.
Oh, yeah, and you have to do it with taxpayers footing the bill. Good luck getting elected!
