Why is garbage in space dangerous?

The clogging of near-Earth space could lead to the "Kessler effect" - a situation where space travel is not possible, as NASA experts warned earlier this year.
Donald Kessler, an analyst at the National Aeronautics and Space Administration, predicted back in 1978 that space debris would eventually accumulate in such quantities that launches would simply be impossible.
When spun at high speed, even a drop of paint can damage the suit if spilled. Experts say that there is no need to talk about the danger of collisions between stations and satellites.
"New space catastrophes can provoke a chain reaction - a cascade effect of collisions of particles with each other, and as a result, the entire space above the Earth will be covered with a thin layer of debris," - said in the message.
In addition, such debris is already interfering with the work of terrestrial telescopes. As a result, the problem of space debris has ceased to seem so distant. Space debris is already falling to the ground in the form of debris. Experts believe that settlements, industrial facilities, transport, communications, and so on are under threat.
Therefore, the wishes of the company in solving these problems are important, I really liked the events with the ecological direction of Dragonfly, more details about the projects on the website dragonflyaerospace.com

The debris danger is common awareness in the field.
'In addition, such debris is already interfering with the work of terrestrial telescopes' - good point, one pulling together several danger factor.

The Earth was always vulnerable to the outer space. Activities, such as solar storms, strike from space much more frequently. These have a direct effect on electronic systems, especially satellite-based technologies. Moreover, the burst of human-made satellites has created a space hazard of its own, as the loads of orbiting debris have the potential to destroy other satellites.

In the US both NASA and the U.S. Space Force tracks space debris, the National Oceanic and Atmospheric Administration monitor space weather, Planetary Defense Coordination Office coordinates the search for potentially hazardous asteroids and other near-Earth objects (NEOs). The European Space Agency (ESA) has pulled all these activities together under the umbrella of its Space Situational Awareness program. The key should be in collecting all the data together and handling it with the help of Data Science methods. These are really good news: NASA and ESA (European Space Agency) are making partnership for several projects.
Those include debris handling.
The Space activities are prolific as never before, and the global partnerships should come and bring order.

The biggest danger it poses is to other satellites in orbit. These satellites have to move out of the way of all this incoming space junk to make sure they don't get hit and potentially damaged or destroyed.

Having 20k+ junk pieces already on the orbit for all the time, it looks inevitable as a result of Starlink, sending 15k and preparing twice more.
There must be mitigation points behind (presumably):
- Where the collision numbers become critical to hold on new launches.
- Automatic manoeuvring systems continuous calibration.
- Emergency actions for the critical collisions that might happen.

When the goal is set and approved, permission is there.
Space junk is the hazard problem that has been there for decades, and nowadays with the space exploration boost we try to surpass it.
