"Europe is the smallest continent. It is not really even a continent—just a subcontinental annexe to Asia. The whole of Europe (excluding Russia and Turkey) comprises just five and a half million square kilometers: less than two thirds the area of Brazil, not much more than half the size of China or the US. It is dwarfed by Russia, which covers seventeen million square kilometers. But in the intensity of its internal differences and contrasts, Europe is unique."
