Space Junk may drive up cost of Future missions.

An Article in New Scientist revealed that scientists fear a "blizzard" of space debris will make future rocket launches dramatically more expensive. With the U.S. now tracking 19,000 objects in orbit around Earth, Hugh Lewis of the University of Southhampton in the U.K. predicts a 50% rise in near-misses over the next decade and a 400% jump by 2059. By that year, his statistics show, satellite operators will have to take five times as many collision-avoidance measures as they will in 2019.
Have any of these scientists calculated the percentage of possible collisions and where the debris may fall onto the Earth? True that the majority of debris would fall into the oceans. But what if it falls on an airborne aircraft, ships in the oceans or possibly land where hundreds could be killed or injured. If you calculate the 19,000 pieces of satellites (Space Junk) divided by the past 29 years of excessive launchings that averages to 655 launches per year. Divide that by 365 days in a year and that averages to a launch every 1.8 days (or every other day). The worlds 46 Space Agencies with their 51 Spaceports located around the world must stop these excessive launches not only to reduce possible collisions, but to reduce constant depletion of the ozone layer.
