human characteristics
There are human characteristics,some good for us, some bad for the ocean. Oil transfer places near the ocean are bad for it,but they're good for us. Subs are bad for the ocean by admitting gas into the ocean, but good for us because they gives us information on the ocean life. If you're on the shore of the ocean you might find a restaurant or a snack bar to attract tourists and what better place to put one with all that beautiful scenery?
