According to a Harvard study, the earth's population will hit seven billion humans in a few months. Earlier this summer, Gadling labs profiled the effects of increasing populations on finite land resources by showcasing the world's most crowded islands. The earth is, in its own way, an island, and 21st century humanity will be presented with the challenge of adapting to rising population levels and static resources.

While countries like India have wrestled with the conundrum of feeding and housing booming population levels in Delhi, Kolkata, and Mumbai, the countries on this list bear no similarities to the billion strong Indian subcontinent. These countries are the ones with open space - lots of it. Countries like Greenland and Mongolia may someday be utilized for their vast expanses of open terrain, but today they are simply great places to go when you have tired of other human beings.

So while this extraordinarily hot summer may have included elbowing your way through thronged midtown Manhattan in 100 degree heat or hesitantly inhaling the stink rising off the sweaty crowd at Bonnaroo, this list is intended to take you way away from the crowds. From riding a horse through the empty steppes of Mongolia to exploring the glacial highlands of Iceland, each of these countries offers exercises in sweet sweet solitude. None of these countries have more than ten people per square mile.
