Some time ago I wrote on this subject. My concerns originated when a "fleck of paint" hit the windshield of the Space Shuttle at a closing speed of something like 17,000 miles per hour and cracked the windshield to the point that experts feared a heavier object would have compromised the Shuttle's survival in space.
Now I read this article, and it is comforting to know experts are also concerned and trying to come up with a solution to the trash heap we are building in earth's orbit.
Now all we need to do is figure out how to do the same thing with that Delaware-size pile of trash in the Pacific ocean!
God help us.
