Kevin Cournoyer's curator insight, April 8, 2015 1:18 PM

It's a little strange to think that one of the world's largest countries in terms of area does not boast a very large population. Then again, when we think of Russia (the largest country by area in the world), many of its regions are uninhabited as well because of extreme climatic conditions. Countries like India, China, and Brazil, however, have enormous populations because they are located in more temperate zones, and so almost every area of the country is habitable.  There are places in every country, however, that are uninhabitable due to the terrain, the weather, or other factors. 

 

What we end up with, then, is the idea of geography as a misleading discipline. Okay, maybe the discipline itself is not misleading, but we have to be careful about making assumptions about a place based merely on its size or location. Some people may assume that some of the world's larger countries have strong and stable economies due to their size, but this is not always the case. Some of the most economically stable countries in the world are found in the relatively small nations of Europe. This map of Canada and the accompanying article, therefore, are a cautionary tale about taking things at face value and the importance of doing our own investigation and research. 

Mark Hathaway's curator insight, September 17, 2015 8:51 AM

Canada is large relatively uninhabitable country. Most of the nation is basically barren frozen wilderness. This article shows the key point that climate plays in the question of where humans decided to live. Warm and temperate climates traditionally attract the most people. Know one wants to live with polar bears. While their are many geographic factors to were people live, climate may be the most important.

Alex Vielman's curator insight, September 21, 2015 11:46 PM

It really isn't much of a shock that one of the world's biggest countries, Canada, does not have a large population. The obvious reason is because the temperatures reach extremely low. Not a lot of people live in Northern Quebec, Yukon, or Nunavut. Its interesting to think that a country so big has mostly all its population in cities along the border line of Canada and the U.S. One of the thoughts that comes to mind is how, Canada has all this 'empty' territory, with little to no activity happening in certain areas, is this land really Canada's to claim? We hear people always talking about the touristic areas like Niagara Falls or Toronto, but what makes places like Nuvavut, Canada? Its almost like if half of Canada is actually Canada. 

Overall, it is completely understandable that no one will want to live in extreme cold temperatures but it would be interesting to learn more about these Canadian States.

Scandinavian Energy Usage

Scandinavian Energy Usage | SDEHS Geography | Scoop.it

Which countries consume the most electricity per person? You might guess the United States would top the World Bank’s list, but the Nordic countries of Iceland, Norway, Finland, and Sweden are actually at or near the top. Icelanders consume an average of 52,374 kilowatt hours per person per year, Norwegians 23,174 kilowatt hours, Finns 15,738 kilowatt hours, and Swedes 14,030 kilowatt hours. Americans are not far behind, with an average consumption of 13,246 kilowatt hours per person. The Japanese consume 7,848 kilowatt hours.

 

This image is part of a global composite assembled from data acquired by the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite in 2012. The nighttime view of Earth was made possible by the “day-night band” of the Visible Infrared Imaging Radiometer Suite. VIIRS detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as city lights, wildfires, and gas flares. The city lights of several major Nordic cities are visible in the imagery, including Stockholm, Sweden (population 905,184); Oslo, Norway (634,463); Helsinki, Finland (614,074), and Reykjavik, Iceland (121,490).

Jared Medeiros's curator insight, February 18, 2015 5:59 PM

It is not surprising to me that these countries, or any country that resides in a high latitude area, have high usage of electricity.  The combination of extreme cold temperatures and times of meager amounts of daylight equal high uses of energy.  High populations of these areas tend to be around the coast as well, so these areas have to work extra hard to keep people warm, fed, etc.  If people were more spread out, the usage might not be as high. 

Lena Minassian's curator insight, February 18, 2015 7:17 PM

This articles discusses which countries use the most electricity and believe it or not, the Nordic countries are at the top of the list. It shows two satellite images in the nighttime for you to get a better visual as to which areas of these countries use the most electricity. There are multiple factors that go into these countries consuming this much energy. One factor that is interesting is the high demand for electricity because of the long winters in these countries. 

Kevin Cournoyer's curator insight, May 6, 2015 9:34 AM

These images are really interesting and expose just how much electricity the Scandinavian countries actually use. It is surprising to think of these nations as large energy consumers because of their general reputation as progressive, clean, and liberal places. This brief article is an excellent example of how maps and satellite images can be misleading, though. As opposed to places like the U.S. or China, energy consumption in the Scandinavian countries actually produces only small amounts of greenhouse gases and is based on renewable energy sources. 

 

This shows an interesting and not immediately apparent geographic distinction between the Scandinavian countries and places such as China and the U.S. Chinese and United States energy consumption is enormous because of those countries' ability and desire to produce large amounts of goods quickly. Household energy use is also high because of the widespread use of electronics such as televisions, computers, and appliances. The Scandinavian countries, on the other hand, have a need for increased energy use because of their geographic location: long, dark winters mean an increased need for electricity and for longer periods. Also, Scandinavia is able to produce energy at lower costs due to its use of renewable energy sources. So though those countries may consume much more energy than their non-Scandinavian counterparts, they are doing so responsibly and for a reason.

Kristin Mandsager San Bento's curator insight, April 9, 2015 2:21 PM

Before I even read the article, my first thought went to the Linneaus classification.  That really damaged history with this one chart.  I think people still think of Africans and blacks(very dark blacks) as dirty or unintelligent.  Which is horrible and couldn't be further from the truth.  Misinforming the public is criminal.  News media and social media need to be careful and educate properly.  I've been asked from a customs offical, "Have you been to Africa in the past 6 months?"  Which is a very blanket question because Africa is a continent.  There were areas that were not hit with Ebola.  

Chris Costa's curator insight, October 27, 2015 4:37 PM

Those who deny the continued influence of racism in our society are blinding themselves to the truth. Contemporary influences of the racism that plagued the preceding centuries are still found in most major media depictions of Africa. The Ebola epidemic has served to highlight the bigotry that plagues Western media, as the assumption that all of Africa is diseased and dirty is continuously perpetuated (when, in reality, Ebola only affected a very small part of the continent). Africa is presented as "other," a backwards continent that is in desperate need of Western help and guidance- in what was is that different from the European colonizers who also viewed their actions as benevolent attempts to "civilize" the uncivilized? That mindset has not left Western circles, and yet we continue to pat ourselves on the back and congratulate ourselves for suddenly being so tolerant. The insensitivity of Western audiences to the concerns of black individuals both at home and in Africa related to the prevalence of racism highlights how determined mainstream media is to deny the existence of a problem. Until we recognize the Eurocentrism that continues to plague our media and make the necessary moves to correct the practice, harmful depictions of Africa will continue to loom large in Western media and in the opinions of many Europeans and Americans alike.

Mark Hathaway's curator insight, October 30, 2015 7:12 AM

Africa has long been treated by the western media as a dark , brutish, uncivilized place. Africa is a place were people starve and murder each other in large numbers. There is so much more to Africa than the picture I just described. The problem is, many people just do not accept the existence of a culturally complex Africa. That narrative would destroy the traditional  darker narrative of the past 500 years. A narrative grounded in the beliefs that blacks are inherently inferior beings. During the Ebola crises, the calls to cut off travel to Africa were quick and demanding. Had the crises been in England, would those same calls have been so loud? I think we all can guess the answer  to that question. Much progress has been made, but we still need to change our cultural depiction of Africa.

Nicholas A. Whitmore's curator insight, December 13, 2015 3:52 PM

An unfortunate side affect of unregulated growth and mismanagement. This turn of events has led to many losing their livelihoods and more than likely has led to the abandoning of at least some villages/towns that may have depended on the Sea. Another great tragedy of all this is the damage to the wildlife in the region. Who knows the kinds of species that were lost. It is a sad day when a landmark disappears and for the Aral Sea it would appear it will become nothing more than a historical memory like the Rubicon. I at least hope something will be done to restore it by finding another place for the cotton production but given this is a dispute involving multiple countries it is unlikely to happen at least in the short term.

Benjamin Jackson's curator insight, December 14, 2015 11:21 AM

this is a demonstration of why you shouldn't just try to alter the environment that you are relying on for  your entire existence in a way that will have effects that you cannot possibly predict.

Adam Deneault's curator insight, December 14, 2015 3:22 PM

The Aral Sea, a once very large sea, is becoming a dried up sea bed. Human irrigation has played an important roll in the decline of the sea. Irrigation created canals and damns that led to the the peoples crops. Since the 1960's when irrigation was started the sea has dried up creating very large beds of salty sand. This sand was not just located around the sea but dust storms pick up the sea and deposit it on the land around the sea creating very large swaths of land that are infertile. This also creates health problems from the salt settling on the crops of the people. 

The dried up sea also creates a environmental issue of less evaporation and less rain for the crops. This also breaks down the ecological system. a area that was once booming with wildlife has been diminished to just 32 species down from the 174 it used to be. what this area needs is a enormous rainstorm or a massive ice melt that hopefully be enough to re establish the sea. This is more then likely not going to happen but its what it needs.

I can relate to this article seeing my research article is about Lake Baikal. You are right it is a bit outdated but most of the 2000 people who have lost their jobs are receiving help from the state even if it is short term. The people who have important skills are being relocated while others are given some other form of training. Others are waiting  for something to open up while in the meantime they are raising chickens and farming. There could be a bright side in the future economically as there has been talk about building a Russian type Disneyland which could produce income and jobs for people. The problem is there is a lot of environmental liquid waste to clean up which is cost effective. But it could attract investors in the future.

Martin Kemp's curator insight, December 17, 2015 1:34 PM

i feel like the problem of choosing between economic problems and environmental problem, deciding which is more important, happens all over the world. especially in this case where the people of baikal where there actually are no other jobs. in situations like this you have to decide if keeping those people alive now is more important than worrying about the environment in the future.

BrianCaldwell7's curator insight, April 5, 8:15 AM

The environment, industry and politics play key roles in this story of an old style Soviet mono-town on Lake Baikal.  Monotowns had planned economies that revolved around one industry and today many of these are struggling in the post-Soviet era.  While the particulars of the political situation are a bit dated, the overall issue is still quite relevant to understanding Russia today.
