Space Junk

Space junk is piles and piles of trash that is spread all across space and Earth. Scientist say that the space junk in space is posing a threat to space activities. They also say that they is becoming necessary to remove some of the space junk. National Geographic says: "Since the launch of the Soviet Union's Sputnik I satellite in 1957, humans have been generating space junk."
I think that space junk is cool but if it's posing a threat to space activities, then they should try to remove some of it. To learn more about this subject go to http://news.nationalgeographic.com/news/2006/01/0119_060119_space_junk.html!
