Top 10 Most Populated Cities In The World

Top 10 Most Populated Cities In The World | Human Geography CP | Scoop.it
Urbanization has led to what are known as mega-cities, cities with a population of over 10 million people. These mega-cities have become so large that they often lead to terrible pollution, traffic, and extreme poverty.

Over half the global population lives in cities, and the problems confronting these megacities will loom large for future sustainability issues--both at local and global scales. This list ranks the cities by city limits and governance jurisdiction (not by the expanded metropolitan area).

This is an interesting article, but it doesn't say how they came to their numbers. It seems like they may only be talking about within the 'city' limits, or some very old data. http://www.citypopulation.de/world/Agglomerations.html has some very different numbers as of the beginning of this year, their numbers however are the entire aggomeration and not just the 'city' limits.

New York -- before the City

TED Talks 400 years after Hudson found New York harbor, Eric Sanderson shares how he made a 3D map of Mannahatta's fascinating pre-city ecology of hills, rivers, wildlife -- accurate down to the block -- when Times Square was a wetland and you...

 

KC: The Manhattan Project created a picture of the area before the development of a city, the way Henry Hudson did during his 1609 exploration. After 10 years (1999-2009), the research project has expanded to study the entire city of New York. The Welikia Project analyzes geography and landscape ecology to discover the original environment and compare it to present day. Scientists have learned that world's largest cities once had a natural landscape of freshwater wetlands and salt marshes, ponds and streams, forests and fields with an equally diverse wildlife community. By focusing on the city's biodiversity of 400 years ago and the modern era, information can be gathered about what has changed, what has remained constant, where the city was done well and where it needs to improve. This source is useful because it allows for the visualization of NYC in a way never seen before. Urban environments, such as NYC, have a landscape largely created by humans, so the skyscrapers, pavement, and mass population is far removed from the landscape it once was.

I was surprised on how green NYC is because of all the cars and urban development. I think this project topic is very informative and interesting (makes me want to got to NYC) . I thought it was very interesting how NYC was in the early 1900s and how it became now. I also think it's a great idea how adding more greenery to the urban city will add sort of a rural feel to a big city.
