The speaker - Zdenko Uvalić - began his talk with a short video available on YouTube channel Gravity - "Detached", which shows what can happen in a collision in Earth orbit. He then pointed out that the Earth's orbit is heavily polluted and presented the history of how space debris is created. He then shared his findings from 60 years of space activity on the amount of debris in Earth orbit, which is constantly and drastically increasing. He pointed out where they come from and how they form. Then he explained what the Keslar syndrome is. This is the theory that a single collision in space sets off an unstoppable chain of collisions, which in turn could block humanity's access to space for many centuries. Next, the speaker talked about why we should be concerned about space debris. One of the most interesting parts of the talk was the plans to clean up space and the methods currently being used for cleaning the Earth's orbit. Finally, he added that it is very important to create a unified international law that will be applies to all countries. A very interesting element of the presentation and at the same time an excellent summary was the presentation of the LeoLabs platform, where the participants could see with their own eyes how many objects, including space debris, are in the Earth's orbit.
