There is a lot of space junk around Earth. This junk comes from old rockets and satellites. About 1,200 pieces fell to Earth last year, and thousands more are still flying. They can crash into each other, break apart and add more junk, which makes space even more dangerous. 
 France has the most junk in space in Europe. It also has many satellites. The UK has many satellites too, but not much junk. The European Space Agency (ESA) wants to stop the junk. ESA is building new tools to clean space. But removing junk is difficult because of money problems and laws. But it is hard because the junk belongs to many countries. 
Cleaning the space costs a lot of money, too. All countries must work together and follow space safety rules to solve this problem.
