TED Talks As Vicki Arroyo says, it's time to prepare our homes and cities for our changing climate, with its increased risk of flooding, drought and uncertainty. Our major cities are suceptible to environmental catastrophes for a whole host of reasons. Cities depend on a smooth of goods, money and services provided by infrastructure that we take for granted and assume will always work 24/7. Presented in the video are some ideas about how we should rethink our cities with a different ecological paradigm to protect our cities more in the future.

It was just over two centuries ago that the global population was 1 billion — in 1804. But better medicine and improved agriculture resulted in higher life expectancy for children, dramatically increasing the world population, especially in the West. This is an excellent video for population and demographic units, but also for showing regional and spatial patterns within the global dataset (since terms like 'overpopulation' and 'carrying capacity' inherently have different meanings in distinct place and when analyzed at various scales). It is also a fantastic way to visualize population data and explain the ideas that are foundational for the Demographic Transition Model.

Our modern society depends on greater connectivity between places. Regionalized economies, politics and transportation networks are increasingly integrated with far-flung places now more than ever before. Our biosphere and natural environments are exceptions to this pattern. Wilderness areas are 'islands' in an ocean of human controlled environments. We create transportation linkages that unite people economies and cities, but separate herds from there extended habitat. We've all seen road kill on major highways. Species like deer, elk, and grizzly bears and other large-bodied animals need a wide range for numerous ecological reasons. These bridges are an attempt to ameliorate some of the problems that our roads pose for the non-human species that still call Earth home. From a purely economic standpoint, many argue that these bridges save society money given the accidents and property damage that can be avoided.

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.

Definate hook to be played a couple times as their minds wrap around what they are seeing! mixed used train-tracks/market place... I've used similar videos in my classes and students are usually quite shocked to see how a city like Bangkok, Thailand operates. I've used this as a 'hook' for lessons of population growth, urbanization, economic development, sustainability, megacities and city planning.
