  • $\begingroup$ it has much less surface water in seas, rivers and icecaps (2-10% of Earths) I am dubious that this lack of water would allow much life to develop in the first place - not life as we know it. $\endgroup$

  • $\begingroup$ @StephenG why do you think so? The seas are still a significant size in some areas - many hundreds of miles across. How large an expanse of water is needed for life to arise? $\endgroup$

    $\begingroup$ This raises just many questions - how does the sea survive ? The Earth is covered by area to about 70% water. You want at most 10% of that, so you are talking about an area of about 7% Earth's area at most, so at most about a 6000km by 6000 km by 6000 km ocean. It's really more likely your populated part is a large island (continent) inside a large sea that is being slowly reduced in size as the climate changes. It's a dying planet, maybe, and this the last inhabitable region ? $\endgroup$

  • $\begingroup$ i dont quite get it, but isnt that basically what arab is? they are isolated by desert and build their civilization on oasis (not due to volcanic though as far as i know), and i mean the one that not part of silk road path, they are pretty much out of radar by other civilization until the rise of islam. $\endgroup$

  • $\begingroup$ @StephenG How does the sea survive? Where is it going to go? 10% of Earths surface water would be enough to cover the entire planet with a layer many hundreds of feet deep. I'm not counting chemically combined water or water deep below the surface. It might be dying but that's not the question. Assume it has enough life left in it for a few million years at least, the population have no idea what is beyond their area. That area is to the north west of a large shallow sea, the prevailing winds blow across the sea to a mountain range where it rains. The rain returns to the sea in rivers. $\endgroup$
