Space debris

At first I'm going to explain what is the space debris, It is the collection of defunct man-made objects in orbit around Earth old satellites, spent rocket stages, and fragments from disintegration, erosion, and collisions including those caused by debris itself.
The universe is increasingly polluted by these objects or space debris, We as people who live on planet Earth, we should be more concerned about issues like this. We must not only worry because these objects damage satellites, also because these objects strike the Earth and they damage it. 
In the space there are a lot of man-made objects, and we should work and propose change these numbers and dominate the universe of natural objects such as stars.
