Answer:
With half a million pieces of space debris cluttering Earth's orbit, according to NASA, this means there is a growing problem of cluttering up our access road to space. Several companies and entities have proposed ways to get rid of derelict satellites and other space junk.

The third error was as a result of adding a comma before the indirect quotation.
The fourth error was as a result of adding an inappropriate comma in the sentence with the same idea.
