This is a great article to include during the teaching of Gravitation. Students learn about how satellites are launched, and are often taught that they will continue to spiral inward as they lose gravitational potential energy and gain kinetic energy and eventually burn up in atmosphere.
However, in reality, we do leave a lot of debris and trash in space and now we are causing problems for ourselves.
A lesson in National Education perhaps? Though not directly related to Singapore, but relates to character development and the care of the environment, and our responsibility as inhabitants of the earth.
