Web-Site: NASA Orbital Debris Program Office

For those who like to work the "Birds" and/or the ISS via radio,
this site doesn't directly address specific satellites orbited and
used solely by Amateur Radio operators world-wide. This organization is
charged to monitor "Orbital Debris as any human-made object in orbit
about the Earth" that "poses a risk to continued reliable use of
space-based services and operations and to the safety of persons
and property in space and on Earth."

"Space junk is a significant concern now that an estimated 100M objects
are in Earth’s orbit. From NASA’s Johnson Space Center, the Orbital
Debris Program Office (ODPO) has taken the international lead in
conducting measurements of the orbital environment and in developing
the technical consensus for adopting mitigation measures to protect
the users within it."

The FAQ: Frequently Asked Questions TAB defines "Orbital Debris"
https://orbitaldebris.jsc.nasa.gov/faq/

FAQ #5. What is the principal source of large orbital debris?
Satellite explosions and collisions. Prior to 2007, the principal
source of debris was from explosions of launch vehicle upper stages
and spacecraft. The intentional destruction of the Fengyun-1C
weather satellite by China in 2007 and the accidental collision of
the American communications satellite, Iridium-33, and the retired
Russian spacecraft, Cosmos-2251, in 2009 greatly increased the number
of large debris in orbit and now represent one-third of all
cataloged orbital debris.

There are a multitude of TABS to explore this and related topics to
include periodic reporting available as a downloadable PDF file

Top Story: The Intentional Destruction of Cosmos 1408
"The Russian Federation conducted a direct-ascent antisatellite (ASAT)
test in the early hours (Universal Time) of 15 November 2021. The target
of the test was Cosmos 1408 (International Designator 1982-092A,
Catalog Number 13552), a derelict Soviet Electronic and Signals
Intelligence (ELINT) Tselina-D-class spacecraft.
... that (produced and later) identified more than 1,500 pieces of large,
trackable fragments associated with the breakup of Cosmos 1408 shortly
after the event."

Top Story: United Nations Adopts Space Debris Mitigation Guidelines
"During its annual meeting in February 2007, the Scientific and Technical
"Subcommittee (STSC) of the United Nations’ (UN) Committee on the
Peaceful Uses of Outer Space (COPUOS) adopted by consensus a comprehensive
set of space debris mitigation guidelines designed to curtail the growth
of the Earth’s orbital debris population."

Chinese Anti-satellite Test Creates Most Severe Orbital Debris Cloud in History
"The debris cloud created by a successful test of a Chinese anti-satellite
(ASAT) system on 11 January 2007 represents the single worst contamination
of low Earth orbit (LEO) during the past 50 years. Extending from 200 km
to more than 4,000 km in altitude, the debris frequently transit the
orbits of hundreds of operational spacecraft, including the human space
flight regime, posing new risks to current and future space systems."

Go to the Photo Gallery TAB and play the NASA generated graphics MP4
2:19 minutes video of objects in Earth orbit that are currently being
tracked. Approximately 95% of the objects in this illustration are orbital
debris, i.e., not functional satellites. The video provides a good
visualization of where the greatest orbital debris populations exist

Yep, Chinese and Russians. Enemies of all mankind everywhere.

imagine if you will, some future "space cleaner" satellite, that uses various ways to attract and collect this debris material, then dispose or treat it a way that it no longer poses a risk to space travel.

it might never happen on its own, but as soon as some major, high visibility mission is wrecked due to debris, then it will happen. 

I wouldn't be surprised if Elon is already secretly working on it as a future business opportunity.
