Which detail from "Space Junk!" conveys the author's viewpoint that something needs to be done about the amount of debris in space? "Currently, there are around 900,000 pieces of debris between 1 centimeter and 10 centimeters in length orbiting in our space system, and this number is growing." "Because humans’ interest in exploring space continues to grow, there is little chance that the number of objects in space will decrease." "Some solutions propose an end-of-life plan for future launches, in which the debris would be sent farther into space or destroyed." "However, as people become more aware of the problem of space junk, the same energy dedicated to exploring space must be directed toward creative ways of cleaning it up."
