"Where have immigrants to the U.S. come from? Natalia Bronshtein, a professor and consultant who runs the blog Insightful Interaction, created this fascinating visualization of the number of immigrants to the U.S. since 1829 by country of origin. The graph hints at tragic events in world history. The first influx of Irish occurred during the potato famine in 1845, while the massive influx of Russians in the first decade of the 20th Century was driven by anti-Semitic violence of the Russian pogroms (riots). Meanwhile in the Austro-Hungarian Empire, army conscription and the forced assimilation of minority groups drove people to the U.S. in the early 1900s. Since WWII, Central and South America and Asia have replaced Europe as the largest source of immigrants to the U.S. Immigration shrunk to almost nothing as restrictions tightened during WWII, and then gradually expanded to reach its largest extent ever in the first decade of the 21st Century."
"Physicist Geoffrey West has found that simple, mathematical laws govern the properties of cities — that wealth, crime rate, walking speed and many other aspects of a city can be deduced from a single number: the city's population. In this mind-bending talk from TEDGlobal he shows how it works and how similar laws hold for organisms and corporations."
When you login to craigslist, it will funnel you to the closest local group. What would that a map of that process look like? I'm not a huge fan of the Central Place Theory (but it is in the curriculum), but maybe this map could help explain some of the ideas of the theory.
Projections of urban growth indicate areas where biodiversity is at high risk.
The AAG Smart Brief is a fantastic source of geographic news. This is what they said about this article: "Areas such as tropical Africa and eastern China are expected to be hot spots of urbanization during the next several years, according to researchers, who used satellite imagery and other data to project future urban expansion through 2030. 'We're not forecasting population, we're forecasting the expansion of urban space,' said Yale University geographer Karen Seto. Their efforts could be used to assist conservation initiatives, Seto noted."

At TEDxPhilly, Next American City editor at large Diana Lind explains why cities should rethink their highway infrastructure.
For generations, the prominent model of urbanism accepted in the U.S. has placed the automobile as the top priority for public places, placing massive highways right in the middle of key downtown areas. Some cities (including Denver, DC, NYC, Providence and Dallas) are rethinking the relationship between urban spaces and the transportation networks.
"By 2025, the developing world, as we understand it now, will be home to 29 megacities. We explore the latest UN estimates and forecasts on the growth of these 'cities on steroids', and take a look at the challenges and opportunities megacities present for the tens of millions living in Lagos, Mexico City and Dhaka."
A fun thought exercise touching on the themes of energy, resources, consumption and sustainability. We all know that we are consuming resources quickly; if we (globally) continue at the same rate of consumption, how long with certain resources last? If a is child born now, what resources would be gone when s/he is a middle aged? A senior citizen? See the animated version here: http://www.amanda-warner.com/samples/whatleft/
After making an infographic depicting how much space would be needed to house the entire world’s population based on the densities of various global cities, Tim De Chant of Per Square Mile got to thinking about the land resources it takes to support those same cities.
"Ever curious about the reaches of the United Nation and what they do? Here's a great video featuring Dr. Binoy Kampmark from RMIT University. This short video can help improve your understanding of the UN, including its role in world politics and policy making."
This is the new and improved version of the familiar map can teach regions (formal, functional, vernacular) as well as the importance on TV markets as a diffusion mechanism for culture. As mentioned by Andy Baker, "This map is also useful for showcasing 'threshold' and 'range' from 'Central Place Theory.' For instance, I ask my students, 'Why are the Mid-Atlantic & California coasts boundaries (range) so small compared to Great Plains teams?'" Great idea Andy!
If All of Earth's Water was put into Single Sphere, from the USGS Water Science School...
"This picture shows the size of a sphere that would contain all of Earth's water in comparison to the size of the Earth. The blue sphere sitting on the United States, reaching from about Salt Lake City, Utah to Topeka, Kansas, has a diameter of about 860 miles (about 1,385 kilometers) , with a volume of about 332,500,000 cubic miles (1,386,000,000 cubic kilometers). The sphere includes all the water in the oceans, seas, ice caps, lakes and rivers as well as groundwater, atmospheric water, and even the water in you, your dog, and your tomato plant."

This provocatively title TED talk would be an excellent resource for discussing sustainable development. What are the economic, environmental, political and cultural ramifications of suggested policies that seek to lead towards sustainable development? What are the ramifications of not changing policies towards sustainable development?
This interesting National Geographic article emphasizes how consumption patterns in the home are connected to some of the serious global issues that we currently face. This article becomes an exploration into how to go about creating a more environmentally sustainable home.
