Hm. CO2 can escape to space...

... just very slowly.
But it seems very likely to me that at least some CO2 that was once part of a plastic toothbrush has left the planet by now...

Why is CO2 not escaping to space?
Answer (1 of 8): It is escaping to space, just not very fast.
Thermal escape involves temperature, molecular mass, and gravity. CO2 has more molecular mass than water, hydrogen, oxygen, or nitrogen. ...

I had to think for a while about how this statement could possibly be true.
The only way is if you count CO2 from plastic that has been burned or mineralized as "in existence in some form".
Which is fair enough, I guess...
