For years, China claimed to hold an estimated 50000 rivers within its borders. Now, more than half of them have abruptly vanished.
China is attributing the disappearance of over 50 percent of their country's rivers to inaccurate sources; more effective technologies today give an accurate picture of China's waterways compared to the former data based off of sources from the 1950's. While it is probably true to some extent that previous numbers were off, there still needs to be much concern for the state of China's current waterways and why waterways that once existed have disappeared.
Cutting corners in safety and cleanliness has caused pollution in the rivers. All the money they saved cutting corners now has to be invested in diverting clean water to northern areas of the country. I hope someday they realize that you cannot do things super cheaply without paying for it in another area.
What has happened to these rivers? Are they purposely being depleted from China? How do they expect to supply water for their residents if they are building things over these used-to-be rivers?
Did you know that in 2000 the IHO created a new ocean called the Southern Ocean? Here, learn about where and what the Southern Ocean is.
Maybe if more of the global population lived in the Southern Hemisphere, perhaps our educational systems would emphasize more information about the Southern Ocean (not to mention acknowledge that it even exists). This body of water isn't just the southernmost part of the Pacific, Indian and Atlantic Oceans; the biology, temperature, chemistry and ocean currents all make it a distinct body of water that circles Antarctica. This is just one of over twenty videos in the "geography" tab from the great folks at about.com.

The southern ocean is a collection of oceans near Australia…. in the southern part of the world… interesting.

It is very sad that people have to move to a polluted, crowded mess of a place in order to get a better life. The man says at the end that if they can make it work in Dhaka, they could make it work in any city but the beginning is too monumental to get over. I think that maybe some government control over the outer limits of the city and offering a place nearby with some resources may allow more control over the growth of the city at least temporarily.
To be a megacity like this, you have to conform to urbanization. There is no possible way to have such a populated and crowed city with farmlands around. This is a place of business yet residential areas, it also is where the marketplaces are and where kids go to school. Megacities need to be a part of an urban society in order for them to stay afloat.
