Agriculture



Agriculture is the artificial cultivation and processing of animals, plants, fungi and other life forms for food,fibers and other byproducts.[1] Agriculture was the key implement in the rise of sedentary humancivilization, whereby farming of domesticated species created food surpluses that nurtured the development of much denser and more stratified societies. The study of agriculture is known as agricultural science. Agriculture is also observed in certain species of ant and termite.[2][3]
The history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. However, all farming generally relies on techniques to expand and maintain the lands suitable for raising domesticated species. For plants, this usually requires some form of irrigation, although there are methods of dryland farming; pastoral herding onrangeland is still the most common means of raising livestock. In the developed world, industrial agriculturebased on large-scale monoculture has become the dominant system of modern farming, although there is growing support for sustainable agriculture (e.g. permaculture or organic agriculture).
Modern agronomy, plant breeding, pesticides and fertilizers, and technological improvements have sharply increased yields from cultivation, but at the same time have caused widespread ecological damage and negative human health effects.[4] Selective breeding and modern practices in animal husbandry such asintensive pig farming have similarly increased the output of meat, but have raised concerns about animal cruelty and the health effects of the antibiotics, growth hormones, and other chemicals commonly used in industrial meat production.[5]
The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials. In the 21st century, plants have been used to grow biofuels, biopharmaceuticals, bioplastics,[6] and pharmaceuticals.[7] Specific foods include cereals, vegetables, fruits, and meat. Fibers include cotton, wool,hemp, silk and flax. Raw materials include lumber and bamboo. Other useful materials are produced by plants, such as resins. Biofuels include methane from biomass, ethanol, and biodiesel. Cut flowers, nursery plants, tropical fish and birds for the pet trade are some of the ornamental products.
In 2007, one third of the world's workers were employed in agriculture. The services sector has overtaken agriculture as the economic sector employing the most people worldwide.[8] Despite the size of its workforce, agricultural production accounts for less than five percent of the gross world product (an aggregate of all gross domestic products).

Diet and Nutrition: Healthy and Sustainable Food Practices



Although this term has not been commonly used to describe health in years past, sustainable health is a growing movement. What is sustainable health you might ask? Well let’s break it down. Health can be defined as a state of “soundness of mind,” or more simply, a state of feeling good. The word sustainability describes the process by which something can be maintained or can keep going. Thus, sustainable health describes being in a state where you feel good not just once but over an extended period of time. 
Today there are many ways to achieve sustainable health, one of the most popular being through the use and production of organic food products. Globally, organic agriculture has helped improve the biological health of human beings while maintaining the ecological ‘health’ of our environment. 
Some of the major areas of interest surrounding sustainable health include: Food additives, animal welfare, biodiversity, community farming, genetic engineering, and pesticides. 


As globalization continues to rapidly spread information around the world, youth are increasingly being exposed to unhealthy diets, which include diets that are high in saturated and trans fats and low in fruits, vegetables, and complex carbohydrates. Probably the most unsettling realities of unhealthy eating practices have been increased risk of diseases such as diabetes, heart failure, malnutrition, and obesity. The World Health organization (www.who.int) reported in 2006 that out of the 1.6 billion adults who were diagnosed as overweight, 400 million of those adults were simultaneously diagnosed as obese in both developed and developing countries.
Research studies in the area of health have shown that educating school-aged children and young people on healthy and sustainable nutritional habits, will increase the likelihood of those children and young people remaining healthy in the future regardless of socio-economic background. These educational programs not only teach nutrition, but they also teach youth how to prepare and handle food in safe and sustainable ways, achieve a balanced diet with limited resources, and to decrease their risk of acquiring a nutrition related disease or disorder. The Theory of Planned behaviour has been used by many research studies on nutrition to predict the factors that affect youth decision-making with regards to eating healthy. In a study by Lautenschlager and Smith (2007), researchers found that youth in a multicultural low-income community in the Unites States of America who participated in a 10-week program significantly improved in nutrition and eating habits. The success of the nutrition education program for multicultural youth identified several factors that were important to positively influencing the nutrition choices of young people, which includes: A nutrition and cooking curriculum that emphasized culturally diverse foods; participatory learning activities (role-playing), sustainable gardening lessons, in addition to skills to fight racism and poverty discrimination (care of the Youth Farm and Market Project, http://www.youthfarm.net). TPB model has also been used to help identify the ecological and cultural factors that affect indigenous youth in the Americas. 



10 Tips to eating and maintaining sustainable health

1. Add a staple food (i.e. fruit, plantain/banana, maize/corn, rice, bread) to each meal.
2. Focus on foods that are high-fibre and low in saturated and trans fats to keep your heart nice and healthy
3. Drink plenty of water. Avoid drinking tea and coffee until 1-2 hours after a meal (when food will have left the stomach) to ensure the maximum amount of absorption of iron by the body supplied in our foods.
4. If you are a youth, you should include food options that are high in iron (especially young women) such as liver, dark green leaves, fish, red meat, and sorghum.
5. Aim for 3 meals and 3-6 snacks per day to create a healthy balance of all your dietary needs.
6. Avoid sugar-rich, sticky, salty, or processed foods and ingredients that are difficult to digest, inhibit healthy growth, and promote pre-mature aging.
7. Exercise regularly for at least 15 minutes at a time.
8. When you are sick, you can decrease the amount of time you remain sick by covering your mouth when you cough and washing your hands regularly. 
9. Get lots of sleep, at least 8 hours of sleep every night, and take naps or siestas throughout the day.
10. Grow, buy, and eat food locally and organically to help your body and the environment.



Micronutrient malnutrition describes the plight of over 2 billion people worldwide (www.who.int) who in most cases do not receive enough foods, and in all cases, do not consume enough nutrients to characterize a healthy and balanced diet. Micronutrient malnutrition has had especially devastating effects for poor pregnant and nursing mothers, whose infants are often born and struggle to live with life-threatening cognitive impairments. Of course other factors besides food consumption play a factor in the persistence of this epidemic, such as: Increased population sizes, people living in poverty, lack of government and foreign aid, and ineffective food policies. The latter (i.e. food policies) has become the focus of many food and health organizations today who see the need for more policies that have in the past neglected to understand “health” in terms of sustainability. Now there is a call for more holistic policies that highlight the interdependent nature of health and sustainable agriculture practices. 


Sustainable health is not just a personal choice; it’s a way for you to affect change in your community. Youth just like you are building sustainable food systems in their community just check out “The Food Project (www.thefoodproject.org)” for just one example of youth making a difference in the area of sustainable health. 

The Amazon: The World's Largest Rainforest


The Amazon River Basin is home to the largest rainforest on Earth. The basin -- roughly the size of the forty-eight contiguous United States -- covers some 40% of the South American continent and includes parts of eight South American countries: Brazil, Bolivia, Peru, Ecuador, Colombia,Venezuela, Guyana, and Suriname, as well as French Guiana, a department of France. 

Reflecting environmental conditions as well as past human influence, the Amazon is made up of a mosaic of ecosystems and vegetation types including rainforests, seasonal forests, deciduous forests, flooded forests, and savannas. The basin is drained by the Amazon River, the world's largest river in terms of discharge, and the second longest river in the world after the Nile. The river is made up of over 1,100 tributaries, 17 of which are longer than 1000 miles, and two of which (the Negro and the Madeira) are larger, in terms of volume, than the Congo (formerly the Zaire) river. The river system is the lifeline of the forest and its history plays an important part in the development of its rainforests. 


At one time Amazon River flowed westward, perhaps as part of a proto-Congo (Zaire) river system from the interior of present day Africa when the continents were joined as part of Gondwana. Fifteen million years ago, the Andes were formed by the collision of the South American plate with the Nazca plate. The rise of the Andes and the linkage of the Brazilian and Guyana bedrock shields, blocked the river and caused the Amazon to become a vast inland sea. Gradually this inland sea became a massive swampy, freshwater lake and the marine inhabitants adapted to life in freshwater. For example, over 20 species of stingray, most closely related to those found in the Pacific Ocean, can be found today in the freshwaters of the Amazon. 

About ten million years ago, waters worked through the sandstone to the west and the Amazon began to flow eastward. At this time the Amazon rainforest was born. During the Ice Age, sea levels dropped and the great Amazon lake rapidly drained and became a river. Three million years later, the ocean level receded enough to expose the Central American isthmus and allow mass migration of mammal species between the Americas. 

The Ice Ages caused tropical rainforest around the world to retreat. Although debated, it is believed that much of the Amazon reverted to savanna and montane forest (see chapter 3-Ice Ages and Glaciation). Savanna divided patches of rainforest into "islands" and separated existing species for periods long enough to allow genetic differentiation (a similar rainforest retreat took place in Africa. Delta core samples suggest that even the mighty Congo watershed was void of rainforest at this time). When the ice ages ended, the forest was again joined and the species that were once one had diverged significantly enough to be constitute designation as separate species, adding to the tremendous diversity of the region. About 6000 years ago, sea levels rose about 130 meters, once again causing the river to be inundated like a long, giant freshwater lake. 

Christmas holiday




There are very few people in the world today who do not know what the Christmas holiday is all about.

There are very few people in the world today who do not know what the Christmas holiday is all about.  Christmas, as we know it today, is the celebration of the birth of Jesus Christ, which happened over 2000 years ago.  The word “Christmas” translates to “Mass Of Christ”.   However, we can all be sure that the celebration of the Christmas holiday did not start right away.  So how did the actual celebration of the Christmas holiday begin? 
Believe it or not, many of the traditions that we observe during the Christmas holiday season began way before the birth of Christ.  Exchanging gifts, decorating trees, and the burning of the Yule log were all winter traditions that began before Christ was born, but were eventually incorporated into the holiday that became known as Christmas, and became part of Christmas history.  
Over 4000 years ago, the Mesopotamians celebrated each new year with a 12-day festival, called Zagmuth.  The Mesopotamians, who believed in many gods, held this festival in support of their chief god, Marduk, because they believed that he battled the monsters of chaos at the beginning of each winter.  It is from this festival that the 12 days of Christmas is believed to have originated.
The ancient Romans held a celebration each year in honor of their god Saturn.  The festival, which they called Saturnalia, began in the middle of December and lasted until the first of January.  The Romans decorated their homes with garlands, as well as trees upon which they hung candles.  During the festival the citizens of Rome would visit each other’s homes and hold great feasts.  One of the theories of how the tradition of the giving of Christmas gifts came about was from the Roman practice of exchanging gifts between family and neighbors during the festival of Saturnalia to promote good luck.

Hitler Becomes Dictator


After the elections of March 5, 1933, the Nazis began a systematic takeover of the state governments throughout Germany, ending a centuries-old tradition of local political independence. Armed SA and SS thugs barged into local government offices using the state of emergency decree as a pretext to throw out legitimate office holders and replace them with Nazi Reich commissioners.
Political enemies were arrested by the thousands and put in hastily constructed holding pens. Old army barracks and abandoned factories were used as prisons. Once inside, prisoners were subjected to military style drills and harsh discipline. They were often beaten and sometimes even tortured to death. This was the very beginning of the Nazi concentration camp system.
At this time, these early concentration camps were loosely organized under the control of the SA and the rival SS. Many were little more than barbed-wire stockades know as 'wild' concentration camps, set up by local Gauleiters and SA leaders.
For Adolf Hitler, the goal of a legally established dictatorship was now within reach. On March 15, 1933, a cabinet meeting was held during which Hitler and Göring discussed how to obstruct what was left of the democratic process to get an Enabling Act passed by the Reichstag. This law would hand over the constitutional functions of the Reichstag to Hitler, including the power to make laws, control the budget and approve treaties with foreign governments.
The emergency decree signed by Hindenburg on February 28th, after the Reichstag fire, made it easy for them to interfere with non-Nazi elected representatives of the people by simply arresting them.
As Hitler plotted to bring democracy to an end in Germany, Propaganda Minister Joseph Goebbels put together a brilliant public relations display at the official opening of the newly elected Reichstag.
On March 21st, in the Garrison Church at Potsdam, the burial place of Frederick the Great, an elaborate ceremony took place designed to ease public concern over Hitler and his gangster-like new regime.
It was attended by President Hindenburg, foreign diplomats, the General Staff and all the old guard going back to the days of the Kaiser. Dressed in their handsome uniforms sprinkled with medals, they watched a most reverent Adolf Hitler give a speech paying respect to Hindenburg and celebrating the union of old Prussian military traditions and the new Nazi Reich. As a symbol of this, the old Imperial flags would soon add swastikas.
Finishing his speech, Hitler walked over to Hindenburg and respectfully bowed before him while taking hold of the old man's hand. The scene was recorded on film and by press photographers from around the world. This was precisely the impression Hitler and Goebbels wanted to give to the world, all the while plotting to toss aside Hindenburg and the elected Reichstag.
Later that same day, Hindenburg signed two decrees put before him by Hitler. The first offered full pardons to all Nazis currently in prison. The prison doors sprang open and out came an assortment of Nazi thugs and murderers.
The second decree signed by the befuddled old man allowed for the arrest of anyone suspected of maliciously criticizing the government and the Nazi Party.
A third decree signed only by Hitler and Papen allowed for the establishment of special courts to try political offenders. These courts were conducted in the military style of a court-martial without a jury and usually with no counsel for the defense.
On March 23rd, the newly elected Reichstag met in the Kroll Opera House in Berlin to consider passing Hitler's Enabling Act. It was officially called the "Law for Removing the Distress of the People and the Reich." If passed, it would in effect vote democracy out of existence in Germany and establish the legal dictatorship of Adolf Hitler.
Brown-shirted Nazi storm troopers swarmed over the fancy old building in a show of force and as a visible threat. They stood outside, in the hallways and even lined the aisles inside, glaring ominously at anyone who might oppose Hitler's will.
Before the vote, Hitler made a speech in which he pledged to use restraint.
"The government will make use of these powers only insofar as they are essential for carrying out vitally necessary measures...The number of cases in which an internal necessity exists for having recourse to such a law is in itself a limited one," Hitler told the Reichstag.
He also promised an end to unemployment and pledged to promote peace with France, Great Britain and Soviet Russia. But in order to do all this, Hitler said, he first needed the Enabling Act. A two-thirds majority was needed, since the law would actually alter the constitution. Hitler needed 31 non-Nazi votes to pass it. He got those votes from the Catholic Center Party after making a false promise to restore some basic rights already taken away by decree.
Meanwhile, Nazi storm troopers chanted outside: "Full powers – or else! We want the bill – or fire and murder!!"
But one man arose amid the overwhelming might. Otto Wells, leader of the Social Democrats stood up and spoke quietly to Hitler.
"We German Social Democrats pledge ourselves solemnly in this historic hour to the principles of humanity and justice, of freedom and socialism. No enabling act can give you power to destroy ideas which are eternal and indestructible."
Hitler was enraged and jumped up to respond.
"You are no longer needed! The star of Germany will rise and yours will sink! Your death knell has sounded!"
The vote was taken – 441 for, and only 84, the Social Democrats, against. The Nazis leapt to their feet clapping, stamping and shouting, then broke into the Nazi anthem, the Hörst Wessel song.
Democracy was ended. They had brought down the German Democratic Republic legally. From this day onward, the Reichstag would be just a sounding board, a cheering section for Hitler's pronouncements.
Interestingly, the Nazi Party was now flooded with applications for membership. These latecomers were cynically labeled by old time Nazis as 'March Violets.' In May, the Nazi Party froze membership. Many of those kept out applied to the SA and the SS which were still accepting. However, in early 1934, Heinrich Himmler would throw out 50,000 of those 'March Violets' from the SS.
The Nazi Gleichschaltung now began, a massive coordination of all aspects of life under the swastika and the absolute leadership of Adolf Hitler.
Under Hitler, the State, not the individual, was supreme.
From the moment of birth one existed to serve the State and obey the dictates of the Führer. Those who disagreed were disposed of.
Many agreed. Bureaucrats, industrialists, even intellectual and literary figures, including Gerhart Hauptmann, world renowned dramatist, were coming out in open support of Hitler.
Many disagreed and left the country. A flood of the finest minds, including over two thousand writers, scientists, and people in the arts poured out of Germany and enriched other lands, mostly the United States. Among them – writer Thomas Mann, director Fritz Lang, actress Marlene Dietrich, architect Walter Gropius, musicians Otto Klemperer, Kurt Weill, Richard Tauber, psychologist Sigmund Freud, and Albert Einstein, who was visiting California when Hitler came to power and never returned to Germany.
In Germany, there were now constant Nazi rallies, parades, marches and meetings amid the relentless propaganda of Goebbels and the omnipresent swastika. For those who remained there was an odd mixture of fear and optimism in the air.
Now, for the first time as dictator, Adolf Hitler turned his attention to the driving force which had propelled him into politics in the first place, his hatred of the Jews. It began with a simple boycott on April 1st, 1933, and would end years later in the greatest tragedy in all of human history.

Alps Railway Tunnel


When the Welsh chronicler Adam of Usk traveled over Switzerland's wild and remote Gotthard Pass by oxcart on his way to Rome in 1402, he was so terrified that he asked his guides to blindfold him so he wouldn't have to look.
He wasn't the first alpine traveler to wish there were another way. For thousands of years, the Alps have been the great barrier to travel and trade on the Continent. To cross them meant a drawn-out, often perilous trip, or at the very least a tough uphill slog.
Not for much longer. For the past nine years, an army of tunnelers has toiled deep in the hard granitic core of the mighty mountain range known as the Gotthard Massif, constructing the world's longest and deepest railway tunnel.
Last October miners burrowing north from the Italian-speaking canton of Ticino met their counterparts who'd been boring south from German-speaking Sedrun to conclude the digging phase of one bore of the double-barreled tunnel—a handshake moment televised live on Swiss TV and broadcast across Europe. In April, the final breakthrough is expected in the second tube.
At 57 kilometers long (35 miles), the Gotthard Base Tunnel will handily outstrip the 50-kilometer (31-mile) Channel Tunnel between England and France and the present record-holder, Japan's 54-kilometer-long (33.6-mile-long) Seikan Tunnel. It will stand alone on the engineering front as well. Where its nearest rivals both pass beneath relatively shallow bodies of water, the Gotthard cuts through the complex basement rocks of a giant, heavily folded mountain range. No one has ever tunneled so deep into a mountain, or to such transforming effect.
When it opens, in 2017, it will render Switzerland, for railroading purposes, as flat as Holland. High-speed passenger trains southbound from Zurich will race along a nearly level course all the way to Milan, booming through the Swiss countryside as fast as 250 kmh (155 mph), flashing in one side of the mountains and popping out the other a few minutes later. It will be as though the Alps didn't exist. Travel time between the cities will drop from nearly four hours to just over two and a half—quicker and more direct than if you flew.
Beating out the airlines isn't why the Swiss are spending $10 billion on the tunnel: They're doing it to shift freight, and to curb the spiraling number of trucks clogging their highways and rumbling through their fragile alpine backyard.
Truck traffic has grown exponentially in the sleek new borderless Europe, especially in the Alps, which straddles the fast-growing economic regions of southern Germany and Italy's industrial north. Quiet, neutral, traditionally aloof Switzerland has become a main trucking crossroads. More than a million trucks a year travel over its passes on winding mountain highways and through alpine road tunnels primarily designed for holiday traffic in the 1960s.
The solution, the Swiss decided, was to boost the capacity of the railways to handle freight. And the best way to do that would be to write the mountains and their famous passes out of the equation: Run a set of tracks straight through the bottom of the mountains and out the other side. With no gradients to climb, trains could haul loads twice as heavy and travel twice as fast as those using the old alpine railways. The Gotthard tunnel alone will be able to handle 40 million tons of cargo a year.
The tunnel begins its journey under the 2,108-meter (6,196-foot) pass in the quiet hamlet of Erstfeld, plunging into a hillside through twin concrete portals. It doesn't come out again until Bodio, more than 57 kilometers (35 miles) away, having crossed one of the Continent's great divides. They speak German when you go into the tunnel; Italian when you come out. A rainy day in the quiet hamlet of Erstfeld is likely to be a sunny one in Bodio, and vice versa.
The tunnel avoids the highest (and weightiest) peaks. Its sinuous path seeks out the most favorable geology and skirts potential groundwater complications with lakes that dot the surface some 2 kilometers (1.2 miles) overhead. Five years and $115 million Swiss francs were spent on fieldwork, drilling, soil samples, and a remote sensing survey to map the massif's nooks and crannies to an accuracy of about ten meters.
Nothing about the Gotthard project is small. In the course of building the tunnel, workers will excavate 25 million tons of rock, enough to fill a freight train stretching from Zurich to New York or, if you're so inclined, to build five life-size replicas of the Great Pyramid. Some of the dross will be dumped in Lake Lucerne to create an offshore nesting area for birds. The better quality stuff will be ground up for concrete to line the passage. In all, some 152 kilometers (94 miles) of tunnel will be dug and lined—two main bores, at 57 kilometers (35 miles) each, plus kilometers of access shafts, emergency escape passages, ventilation ducts, and crossover points, so trains can shift channels when tracks need repair or maintenance.
