The problem of space debris stands out sharply, and I agree with you that it should be solved as soon as possible, but it's so hard to vote in your poll for me because I suppose that each method of deorbiting space debris has the right to exist, has advantages and disadvantages and so on. I see no one mentioned a laser system. I saw several concepts that presuppose the use of lasers based either on Earth or in space, and these lasers will destroy large pieces of space junk.
Space tug is something completely new for me, so I need time to explore this concept.
