SpacePerhaps in the not so far future , new professional figures will be necessary, as for example cosmic sweepers or better, space ecological workers.... There really is a need for them. It has been estimated that today hundreds of millions of space debris are moving around the innermost areas of the Solar System. In the future it will be necessary to take action to decrease, or better, to stop the addition of more space waste, and perhaps clean up the existing waste. The motto could be: the atmosphere belongs to all of us, keep it clean!
