Kaitlin Young's curator insight, October 7, 2014 11:27 AM

The Aral Sea’s receding waters could prove fatal to the surrounding agriculture. Both Uzbekistan and Kazakhstan diverted the rivers that flowed into the Sea in the 1960s to feed their growing cotton and rice farms. Over the last five decades, the lack of a water source flowing into the Aral Sea combined with harsher droughts due to climate change have caused the water to evaporate at an alarming rate. As the water evaporates, large deposits of minerals remain on the bare lake bed. Winds pick up the mineral deposits and often spread them onto farms, where the increased salinity destroys rice paddies and other crops. The destruction of crops causes less food production, so less money is made by the farmers and more money has to be spent to bring in food to avoid famine. Cotton crops are also destroyed, so the region loses yet another source of income.

The increased evaporation of the Aral Sea has also caused an incredible increase to salinity levels in the lake itself. The extremely salty water cannot be used without heavy removing the salt, which is incredibly unaffordable in an already stressed region. Small subsidence farmers and local farmers cannot use the resource at hand. The fishing industry has completely collapsed, thus removing another important resource from the area.

If a wounded economy and unreliable food was not enough, the air born minerals blown away from the lake are causing numerous health problems. Respiratory issues, such as asthma, are becoming more and more common in the communities surrounding the Aral Sea due to the minerals and industrial debris in the air. The disappearance of the Sea has created the perfect conditions for the collapse of a region. The struggle that the people have to endure often escalates into increased social and political unrest, and disputes often occur. The Aral Sea exemplifies how one small environmental change can set off a chain of devastating events that lead to irreversible effects.

The drying of the Aral Sea opens our eyes to how fragile our environment is and the scarcity of resources.  We need to become more aware of our resources, because as they saying goes, the "well will run dry."

Kevin Nguyen's curator insight, December 7, 2015 1:14 PM

The massive changes to the Aral Sea can clearly be seen through the course of a decade. It's so unbelievable that from 2000 on ward it shrunk significantly and the video also showed the development of agricultural land that surrounds the rivers feeding into the Sea. The more water being irrigated and are not putting into the Sea the more it dries up because the water is evaporated with little to no rain going back to it. This is definitely one of the worst man-made disaster that have happened to this region.

8 Great TED Talks to Teach Students about Climate Change

8 Great TED Talks to Teach Students about Climate Change | HISTORIA Y GEOGRAFÍA VIVAS | Scoop.it

While climate change is a hotly debated topic especially in mainstream media yet a lot of people are not well aware of its deep implications on the life of species on the planet earth. The major part of climate change is caused by human activity (e.g pollution, deforestation, burning fossil fuels…etc) leading thus to a huge increase  in the release of carbon dioxide into the atmosphere. The result: unexpected change of weather patterns with an unusual global warming.

How Eratosthenes calculated the Earth's circumference

"In the mid-20th century we began launching satellites into space that would help us determine the exact circumference of the Earth: 40,030 km. But over 2000 years earlier, a man in Ancient Greece came up with nearly the exact same figure using just a stick and his brain."

Seth Dixon's curator insight, November 1, 2016 1:19 PM

Eratosthenes is often referred to as the "father of geography" for creating meridians and parallels on his maps to organize global information, classifying climatic zones, and as shown in the video, calculating the circumference of the Earth. Plus, he coined the terms so he gets the credit. If you have never pondered the meaning of the word "geometry," the accomplishments of Eratosthenes will certainly show that the mathematical prowess was at the heart of expanding our collective geographic knowledge (additionally, here is a retro Carl Sagan in a video clip from Cosmos that inspired this clip).

"The map above, created with data from Telegeography, shows how those cables have developed since 1990. Most existing cables were constructed during a period of rapid growth in the mid-2000’s. This was followed by a gap of several years during which companies steadily exhausted the available capacity. Over the last few years, explosive new demand, driven by streaming video, has once again jumpstarted the the construction of new cables."

Four maps that explain the chaos of the Middle East

Four maps that explain the chaos of the Middle East | HISTORIA Y GEOGRAFÍA VIVAS | Scoop.it

"Without trying to defend or absolve U.S. policy, then, it is worth stepping back to ask what shared historical experiences might have left these four countries — Iraq, Syria, Libya and Yemen — particularly at risk of violent collapse. The following maps help highlight how, at various points over the past century, historical circumstances conspired, in an often self-reinforcing way, to bolster the stability of some states in the region while undermining that of others."

These maps are not cartographically inspiring, but the it's the historical and political insight that makes them valuable. The goal of this set of maps is to find some underlying causal reasons for political stability(or more importantly instability) in the Middle East. These four maps focus on these key issues:

1. Century-old states are more stable today

2. Colonial rule led to fragile states

3. Instability and regime change

4. The shadow of the Cold War

Mekong Delta fights losing battle against salt water

Vietnam's rice region is facing the worst drought to date. Over half a million people have been affected, and the country could lose one million tons of its staple food.Leaders of six countries along the Mekong River met in China to discuss the relief measures.

Seth Dixon's curator insight, August 18, 2016 2:49 PM

Economic progress for some often entails job loss and environmental degradation for others.  As dams upstream are slowing the flow of the Mekong River, the low-lying delta that is a rich agricultural region is facing the ocean water that is moving further inland.  The once isolated and remote Mekong is experiencing some impacts of globalization.

“The reason that we have so many myths associated with Thanksgiving is that it is an invented tradition. It doesn’t originate in any one event. It is based on the New England puritan Thanksgiving, which is a religious Thanksgiving, and the traditional harvest celebrations of England and New England and maybe other ideas like commemorating the pilgrims. All of these have been gathered together and transformed into something different from the original parts.”

Norka McAlister's curator insight, April 5, 2015 8:01 PM

Citizens of Syria have experienced difficult times since their country entered into a period of continual war in the past few decades. People migrate to Europe in demand of better life for their families. All begin with a plan and a &helper,&  called trafficker or coyote in Mexico, and money to cross few borders and be able to live life free from war. Although, with countries such as Egypt, Lybia, Lebanon, Turkey, and Greece, with a massive migrations, tough economies, lack of jobs, nothing and no one is safe. However, Europe is very attractive in terms of quality life and safety to raise families. Furthermore, to be able to survive during this migration transition, many risks are involved and even in some cases, killings. Immigrants migrate by boat, truck, train, and sometimes even walking. Day or night immigrants keep moving and pay  high prices to be transported to the next point. It takes them weeks, months, and even years to reach thier final destinations. This is the same for those immigrants in Mexico and U.S.

What's the tallest mountain on Earth?

What's the tallest mountain on Earth? | HISTORIA Y GEOGRAFÍA VIVAS | Scoop.it

"Mount Everest is usually said to be the highest mountain on Earth. Reaching 29,035 feet at its summit, Everest is indeed the highest point above global mean sea level—the average level for the ocean surface from which elevations are measured. But the summit of Mt. Everest is not the farthest point from Earth’s center.

Earth is not a perfect sphere, but is a bit thicker at the Equator due to the centrifugal force created by the planet’s constant rotation. Because of this, the highest point above Earth’s center is the peak of Ecuador’s Mount Chimborazo, located just one degree south of the Equator where Earth’s bulge is greatest. The summit of Chimborazo is 20,564 feet above sea level. However, due to the Earth’s bulge, the summit of Chimborazo is over 6,560 feet farther from the center of the Earth than Everest’s peak. That makes Chimborazo the closest point on Earth to the stars.  

You may be surprised to learn that Everest is not the tallest mountain on Earth, either. That honor belongs to Mauna Kea, a volcano on the Big Island of Hawaii. Mauna Kea originates deep beneath the Pacific Ocean, and rises more than 32,800 feet from base to peak."
