China's Water Crisis

China's Water Crisis | Human Geography CP | Scoop.it
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?

The Southern Ocean

The Southern Ocean | Human Geography CP | Scoop.it
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.

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

James Hobson's curator insight, December 8, 8:37 AM

(Oceania topic 1)

[This topic area includes Australia and Antarctica]

I think this video conveys two clear messages. First, geography has a subjective factor to it; where you live and the regions you frequently reference determine how you think about other places: how much you think about them, why you think about them, how different they are from your own norms, etc. I agree that this is why so few people from the Northern Hemisphere regard the Southern Ocean as its own entity. I also believe a subconscious factor in involved, in which human though has a natural inclination to ignore that which is referenced as at the bottom or low (in this example applying to a latitude).

   Secondly, and perhaps more importantly, is that there is more than what meets the eye. Yes, even I agree that from a purely physical sense of geography, the Southern Ocean can just be absorbed into the southern extents of 3 others. However, the visualization of the currents and biosphere are spot-on evidence to support the contrary.

   I hope that this example will lead future geographic definitions to be based not solely on physical reference, but on other factors (including these mentioned) as well.

While many typically assume that maps and even geography itself is rather static and able to change or be altered this video shows the opposite. As the way the earth is seen changes so are maps and they way geography is taught. In some cases the shifting borders aren't only from political shifts as one might imagine but also from the discovery and deciding of things such as this. Like history, geography is a ever changing and shifting field of work.

Megacities Reflect Growing Urbanization Trend

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.

Jess Deady's curator insight, May 4, 8:50 PM

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.

Bec Seeto's curator insight, October 30, 6:07 PM

This is a great introduction to the demographic explosion of the slums within megacities.  This is applicable to many themes within geography.
