Assuming we could collect space trash, it seems easier to bring it back to earth and recycle it. I understand that most people think everything we see is ours to despoil, but I have a problem with the thought of using another planet as a dumping ground.

In the early days of space flight, flights were few and space was big so we designed things to just either burn up in the atmosphere on reentry or be left in space as junk- saves effort and money. But that doesn't scale up, and now we actually are hampered by space junk. We're designing vehicles to be more reusable and recoverable, and so it would be better to look towards a future where we don't generate space junk to begin with.
