i ordered a book about a country that was submerged called doggerland, that until 6,000 years ago connected britain with mainland europe and now lies under the north sea. is it true? i looked it up but who knows with the world wide web. i guess it doesn't matter, if it's possible it's true right. and it sure looks possible today. why was it called doggerland? i could wait for the book...ah, fuggit i'll ask the web. it's name comes from the term for dutch fishing boats. 
i think naturally about how we'll adapt to the rising waters, when cities and countries are submerged. i imagine this lacustrine city being discovered someday.
