There is plenty space in the ocean. We could put all human trash ever created and put it in a box and sink it somewhere in the ocean. there is more than enough space. The problem is we cant make that box and without the box it affects the life. Earth orbit however doesn't have anything that could be affected by trash beside what we put there and deem to not yet be trash. Also keep in mind that humans may have put several hundred tons into orbit by now in total which is basically nothing if you compare that to the millions of tons of plastic that goes to the ocean every year. And ofc there are many many other things than plastic that ends up in the ocean as well. also most of the stuff we put in orbit came or crashed back to earth especially the large and heavy stuff like MIR and the space shuttles.
