The Kessler syndrome, also called the Kessler effect, collisional cascading or ablation cascade is a scenario in which the density of objects in Low Earth Orbit (LEO) is high enough that collisions between objects could cause a cascade where each collision generates space debris that increases the likelihood of further collisions. One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges impractical for many generations. Every satellite, space probe, and manned mission has the potential to produce space debris. A cascading Kessler syndrome becomes more likely as satellites in orbit increase in number. The most commonly used orbits for both manned and unmanned space vehicles are Low Earth Orbit (LEO). Clearly, the number of space debris that naturally falls back into the atmosphere is less than the number of those generated by the collision of existing space debris. Even if all space activity and launch were halted tomorrow, the debris population would continue to increase exponentially, leading to a situation in which some orbits would become impassable in the long run.
This is a quote from an article on spacelegalissues.
The article is almost 2 years old. Has any effective solution been proposed since then?
Or is it a contrived problem?

TommyJ

I've read several articles that offer completely different approaches.
Scientists propose the use of various devices. Laser guns, space tugs, space debris catchers, etc. Many of the devices are real. Others are under development.
Economists propose to introduce a tax on the use of the orbit. The tax should be levied in all countries that make launches, should be the same and start at $ 14,500 per year.
Which way can be more efficient?

A pretty good proposal for solving this problem is the obligation of all participants to calculate the risk of the collision before launch.
But this only solves the problem of increasing space debris. According to many articles, even without an increase in the amount of space debris, the cascade effect can, in the long term, lead to a catastrophic increase in the number of orbital debris objects in LEO and, as a consequence, to the practical impossibility of further space exploration. It is assumed that "after 2055, the process of self-propagation of the remnants of human space activities will become a serious problem."
How many space tugs do we need to solve this problem?

There would be something to come around to deal with the problem. They might not tell us about it, but it's amazing what simple things like magnets can do.

Unfortunately, magnets can only be effective at short distances. At very small distances by cosmic standards.
There is already a solution. Space tug, debris catcher, etc. It remains to wait until they begin to apply it.
