This here is a plain, simple, good old-fashioned map of our planet:
As everyone here would know, land makes up only 29% of the planet's surface. But suppose for a moment that someone has pulled the plug off the ocean to drain enough of the ocean's waters to raise the percentage of land to exactly 50%, not a fraction more. Using our current knowledge of ocean bathymetry, what would a map of such an Earth look like?
Quick disclaimer--I'm not asking for how this change would affect the atmosphere, the ocean currents, the geography, the climate--that's all for later. Simply what the plain, basic, good old-fashioned map would look like. That's it.
