Another 3,000 satellites. Sooner or later I foresee the Kessler effect happening and a disaster up there resulting in no working satellites at all and just a blizzard of bits of metal flying around; preventing the launch of any more satellites and the end of space exploration for another 50 years or however long it would take for enough of the bits to fall back to Earth.
Just think, no GPS, very little Internet, loss of TV and telephone signals. It will be like going back to the 1950's.
No facebook either - so maybe not a bad thing after all.
