What is the gulf between Russia and Finland called?

Daisy, I suspect that in the 1700s it was Nature doing the damage to humans! Of the pollutants mentioned I think only copper would have come from that era, most of the rest are probably of recent Russian origin

I find that even as far back as the 1700s, is astonishing for us humans, the devastating impact we have on our planet and wildlife... and even more astonishing we are still doing it :((
