Answer 1

It would kill off a lot of not-ocean-based living things (including you, if you drank it for long enough), but the things that live in the ocean are, by nature, adapted to it. So the kinds of things that can infect ocean life, which obviously have to live in the sea, aren’t stopped by the salinity of ordinary seawater.
