TL, DR: tourism is bad for nature and your health, and importing PlayStations from China even more so. Buy locally and sell locally whenever you can, and travel on light vehicles.
Just to be clear, buying a video game from your local store or importing it from China is exactly the same thing from an environmental point of view. The game you buy locally was NOT made locally, it came from some factory halfway across the world just as the game you imported yourself from China. The same goes if you import a Playstation or if you buy it locally.
