This is more or less accurate rendering of how Earth surface would look if there would be more water on it (50 to 100 metres, cannot tell more precisely because the image I used for reference did not include measurements). Answering your possible questions - no it is not about 2012, apocalypsis, or humanity in general. It's simply geologic curiosity :-) More: http://www.vladstudio.com/wallpaper/?flooded_world_map Thanks!
