Now there are more than seven tons of space debris in space, which is not so much for the space, but for us, even this amount can create problems and accidents. Kessler Syndrome is a theoretical development of events in near-earth orbit when space debris resulting from numerous launches of artificial satellites, makes near-earth space completely unsuitable for practical use. In short, when two particles of debris make up several. Therefore, this problem already exists. There are already several ideas for solving these problems, such as vacuum cleaners, laser magnets,s, and others. But also don't forget that there are similar problems on Earth. I liked the ambitions of Dragonfly, an environmental company that is interested in these issues and has already managed to create technologies, more info about you can read on their website.
