The reasons given, by the UK engineering team planning to “harpoon” the debris for it then to burn up in the atmosphere, is to assist the modern needs of GPS, weather forecasting and communications, all of which can be impeded by old satellites circling aimlessly around the Planet. They will be helping humans play with their electronic toys, in effect – but large, uncontrolled pieces of hardware which collided with a planetary object, for example, could cause damaging and potentially lethal repercussions, and for me this is a far more important justification for cleaning up the junk we have left behind, as well as that of helping the cosmic environment.
Is there any place that man has touched that has not been left polluted, I wonder? The seas, the skies, the land, the heart of the earth…….to share them is part of the Plan of God, not to abuse and then discard them as we turn to the next plaything that catches our desirous attention. We will reap what we have sown, and there is still time to learn from our mistakes, and do it differently next time.
