Spy satilite shot down ! Part 2

The Pentagon made an official announcement today that the missile the Navy fired last Wed . did indeed destroy the crippled satellites fuel tank . Thus destroying the highly toxic hydrazine fuel in its tank . The U.S. military is currently tracking some 3,000 objects reported to be no smaller than a football . So here's what i don't understand . You have environmentalist that freak out every time NASA or the military send up a satellite fueled with anything other than liquid oxygen , worried that if it crashes it will cause some kind of contamination wherever it lands . Yes from time to time man made objects do fall out of orbit and strike the surface , however by the time those objects pass through the stratosphere air friction has burned the objects down to pieces not even 1/3 the size of the original object . Think about it for a minute . We're not talking about meteorites or asteroids made of nickle or some other type of dense iron - ore , that can withstand the high heat , atmospheric pressure to make it all the way to the surface . Yes we build satellites that can withstand the rigors of space , but not reentry . I sometimes think these tree huggers were absent during 7th grade science class . My opinion , whatever collage or institution of higher learning these environmentalist got there degrees from should go back and demand a refund , obviously they didn't get they're moneys worth .
