I speak a kind of wild mix of British English and American English. Like my pronunciation is probably closer to British but I’ll also use some American terms, like “sidewalk” instead of “pavement”. I guess it could be considered a variety of Euro English.
I speak standard (German) German, with a slight dialect of my region.
Just not polluting it further would do it. It’s a river, so almost everything will get washed away and within a couple decades it will be pretty clean.
