Assuming an open air valley/canyon/depression, how far below sea level would it be plausible to live more or less normally? It looks like the lowest open air land on earth is in the Dead Sea region at about 413 meters. Is this about rock bottom (you should pardon the pun) or could people feasibly live lower down given open land?
I know there are mines that beggar that depth. The deepest seems to be around 3500 meters, but lies at an altitude of around 1440 meters, giving it's floor an altitude of around 2050 meters below sea level. There are significant issues with pressure down there, but I haven't been able to really ascertain how many of them are due to the fact that there's 3500 meters of rock pressing down on it.
Would it be feasible, for instance, for people to live and thrive at around 600 meters or so below sea level?
Thanks.
