Humans are an infant species, a mere 150,000 years old. But, armed with a massive brain, we've not only survived, we've used our wits to adapt to and flourish in habitats as varied as deserts, Arctic tundra, tropical rainforests, wetlands and high mountain ranges. David Suzuki

The history of economic geography of the study of the location of economic activity is more like the story of geological thought about the shapes and location of continents and mountain ranges. Paul Krugman
