Not quite a compare - you can move house, you can’t move planet. It’s not that I would stop looking after my own garden if my neighbours weren’t looking after theirs. It just feels pointless. Using your analogy, if all surrounding neighbours had rotten rubbish in their garden, no matter what you would do, it would still stink in your garden.
