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.
"During the past two years, Kien Lam went on the kind of trip most could only dream about. The photographer wanted to "see as much of the world as possible," so he visited 15 countries around the globe, from Mexico to New Zealand, snapping more than 10,000 photographs along the way. He edited his work together to make this stupendous time-lapse, which may be one of the most envy-inducing travel diaries I've ever seen."
"Food. It’s something we all think about, talk about, and need. Food has been one major topic of interest at National Geographic because it connects all of us to our environment. The recent global population projections for the year 2100 just went up from 9 billion to 11 billion, making the issues of food production and distribution all the more important. For the last 3 years I’ve stored podcasts, articles, videos, and other resources on my personal site on a wide range of geographic issues, including food resources. I thought that sharing 10 of my personal favorite resources on the geography of food would be helpful to understand our changing global food systems."
"Some four decades after welcoming foreign assembly plants and factories, known as maquiladoras, Mexico has seen only a trickle of its industrial and factory workers join the ranks of those who even slightly resemble a middle class."
Despite making such consumer goods like BlackBerry smartphones, plasma TVs, appliances and cars that most people in the US, for instance, consider necessities, Mexican workers in these factories seldom get to enjoy these items because, as this article argues, the labor system keeps them in poverty. Foreign investment in these businesses keep unions out and attracts workers from poorer areas, allowing low-cost labor to prevail. Less than $8 a day is the going wage - great for the bottom line and consumer prices but very bleak for those who toil in this system.
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.
There may be a counterintuitive explanation for the deep freeze that hit New England this winter: The rapidly warming Arctic is causing big disruptions in the jet stream, which carries weather across North America. Is this the worst winter you've experienced?

nat geo programme about the coke factory and the manufacturing process of coke...
Where is Coca Cola produced? Some products are bulk losing some are bulk gaining in the manufacturing process. Coca Cola and their containers represent bulk gaining products. Although not the focus of this video, what is the geography behind where these factories are located? How would this geographic pattern change if this were are bulk losing industry? What are examples of bulk gaining and bulk losing industries? Why are glass bottles not manufactured in the United States?
The death and life of the industrial corridor linking New York and Washington.
This article is a great example of analyzing the landscape to observe changes in any given place. This corridor is home to 8 of the 10 wealthiest counties; at the same time this transportation corridor is also home a half a dozen of the country's most broken cities. Exploring this area is way to analyze the changing economic geographies of the United States. For a visual representation of these same themes, see this 5 minute video that corresponds to this NY Times magazine article.
