And no, not everything has turned virtual! We still rely on concrete stuff. Cables network says a lot about the way our World works. 

Logan Haller's curator insight, May 25, 2015 9:07 PM

This article deals with unit 1 because it has to do with maps. This map shows how underwater cables connect the internet throughout the world. The cables transmit 99% of international data instantly. On this map you can also see latency. Another map in this article shows 1912 trade routes and underwater cables today. The routes are similar and the interdependency has stayed but the methods and meanings for each of these things are different. To pass the ocean is risky by the investments, and trading. Sailors took tHess risks and now the tech companies are taking them. The cables are thin in the deep water equalling 3 inches across. In addition the cables are thicker in shallower water. The interesting thing is these cables can go as deep as Mount Everest is high.

Explore the cities and emerging urban clusters that will drive dramatic growth and demographic changes over the next generation. A McKinsey Quarterly Economic Studies article.

 

In the next 13 years, 600 cities will account for nearly 65 percent of global GDP growth. That is reason enough to explore this global dataset with over 2,600 metropolitan areas.

The Geography of a Pencil

A film from the Competitive Enterprise Institute, adapted from the 1958 essay by Leonard E. Read.

 

This year's Geography Awareness Week's theme was "Declare Your Interdependence!"  The GAW poster for 2012 focused on the Geography of a Pencil and this video works together nicely as a supplement to that poster.  You may see the economics of capitalism and globalization in a less optimistic light than Leonard Read, but the theme of interconnectedness makes this a great resource.

The Rise of Megacities

The Rise of Megacities | general geography | Scoop.it
By 2025, the developing world will be home to 29 megacities.

 

Through this interactive mapping feature with rich call-out boxes, the reader can explore the latest UN estimates and forecasts on the growth of megacities (urban areas with over 10 million residents).  These 'cities on steroids' have been growing tremendously since the 1950s and present a unique set of geographic challenges and opportunities for their residents.

Very cool!

World cities and megacities - Presently , the mega cities of the world have to have a population of at least 10,000. Many cities are very near the minimum to be considered a mega city, but are not quite there. By 2025, the developing world, as we understand it now, is estimated to be home to 29 megacities.
