Living in a submarine Vs spaceship persuasive writing

I firmly believe that it would be better to live in a submarine that never surfaces rather than a spaceship that never lands. This is because it would probably be easier to collect food in a submarine compared to a spaceship. For example, if you ran out of food in a submarine it would be much easier to hunt fish, though if you were in a spaceship food would eventually run out and it would be impossible to re-collect any more. Plus, visualise the enchanting coral reefs and the ocean life you would encounter every day all around you.
