Very beautiful! I really like your prose, it's very "realistic", as if it were really the words of this "trashonaut".
I was fascinated by the naturalness with which you make worldbuilding in the middle of the speech.
Another thing that has impressed me is the ecological message. What you draw could be very close to our real near future. Your story is a very smart and funny way to make people think and raise awareness.
We hope to be able to face climate change and the necessary change in our way of life with positivity and hope, even if not sweetened, that emerges from your story!
