The Food Security Challenge For A Growing Population Essay

INTRODUCTION All over the world, one of the most complicated of the unsolved problems is how the world will feed itself. According to Abraham Maslow in his theory of psychological needs postulated that food is the important basic need of man. When a man is satisfied with his needs for food he pursues other needs of clothing and shelter. The Food security challenge for a growing population was an alarm raised by Thomas Robert Malthus in â€Å"An Essay on the Principle of Population†, to bring our consciousness to the topic of the food crisis in Nigeria. When Malthus posed the challenge of feeding the world population, there were around 900 million, but now we have 7.2 billion people on the planet and with the global population continuing to grow by around 75 million people per year, the challenge of feeding the planet is with us again and a solution must be reached. With various scientific advances, many believed there was a breakthrough in â€Å"food productivity† and as such a permanent solution to the problem of food crisis was found but unfortunately, the problem is unsolved. Sadly, as there is no solution yet on the current food crisis experienced all over the world, many national governments are embarrassed and have placed much effort in the process of yielding huge food production to feed the rapid, nationwide populations surge; providing raw materials to support their development is also one of their effort towards a good and sustained economy for their countries.Show MoreRelatedThe 2050 Food Security Challenge1292 Words   |  6 PagesThe 2050 Food Security Challenge, is one of the most widely known and concerning issues of the 21st century due to its vast potential of impacting the entire earth.

Greek Inspired Architecture in Boston Assignment Essay Example For Students

Greek Inspired Architecture in Boston Assignment Essay My first discovery of classical architecture was made the moment I stepped outside my apartment, as my building has two Doric columns framing the front door. As I meandered over the hill and across the Common I realized exactly how prevalent classical architecture really is. Elements of classical architecture can be found on almost every building in the old residential neighborhoods and many commercial buildings feature columns and arches as well. I saw all three orders of columns, arches, and even a dome. The only architectural element I was unable to find was a iron vault. The Massachusetts State House, about half a block from my apartment, has many examples of classical architecture including a large gold dome, twelve Corinthian columns, and seven arches visible from outside. The State House, which houses the state legislature and the governors offices, was built in 1798 by leading architect of the time Charles Bullfinch. The dome was originally made out of wood shingles but has since been sheathed in copper and covered in 23 karat gold. (http:// www. Satisfaction. Gob/formalities/mischievousnesss. Asp) As far as I observed he arches and columns follow the rules of the classical orders except that the frieze above the columns is blank. Im not sure if the frieze above Corinthian columns is traditionally blank or not. A pioneer, which signifies the importance of the logging industry in Massachusetts, tops the dome. Http://www. Satisfaction. Gob/formalities/ mischievousnesss. Asp) I doubt this would be found on domes of the ancient world. Just as classical architecture was meant to convey power and grace in Ancient Greece and Rome, Im sure Charles Bullfinch used elements are classical architecture n the design of the State House for the purpose of conveying the wealth, power, and beauty of the government and state of Massachusetts. Another building that incorporates classical elements is the Boston Museu m of Fine Art. The current MFC building was built in 1909. There are rows of ionic columns and construction that looks like post-and-lintel. In the area that would be the frieze it says Museum of Fine Arts which could probably be loosely considered a continuous frieze. It was especially interesting to me to see the post-and-lintel type openings since most alluding seem to prefer the Romans arches over the Ancient Greek post-and-lintel system. The Museum of Fine Art is another building that, due to its purpose, should convey an air of greatness. The last building I would like to use as an example is my apartment building, which was built in 1909. There are likely hundreds of residential apartment buildings in the area whose doors are flanked by a column on each side, particularly the apartments that were built in the early sass. The columns of my apartment building are of the Doric order but the abacus of each is rounded, not angular. (Strickland pig 15) There is a session but no cornice, pediment, or any other aspect of the Doric order. At night the columns are illuminated. It is clear by the emphasis the building management places on the columned entrance that they believe it to denote a sense of wealth, greatness, or class. While the State House and MFC certainly do this, I find my building does not quite succeed. It feels that without any other of the classical elements the columns are lacking. T is particularly interesting to me now long classical architecture NAS been in style. It as been used for centuries on everything from prominent government buildings to much more humble residences. Architecture that was once reserved for temples and important public spaces can now be found on everything from strip malls to pharmacies. An important difference in the use of the classical architectural elements is that Ancient Greeks built in their style partly for the logical purpose of creating a building that will stand. Today, even more so than in Ancient Rome, many aspects of the architecture are purely ornamental. Http:// consistory. Schenectady. Org/temple-of-portentous. HTML

Media Bias in the Israel/Palestine Revolution Essays - Middle East

Media Bias in the Israel/Palestine Revolution Sarah Osorio Jae Revolutions June 7, 2017 Bias is a feeling or thought that is created with the person's beliefs and not facts. When people explain their bias, they usually try to get others to think the same way they do. Because of this, we are sometimes subjected to a close minded way of thinking. This is seen quite often in our everyday lives. We find bias in textbooks, the people around us, and especially in media. There is especially room for bias in the Israel/Palestine conflict since it is such a controversial topic. The country of Israel is in the Middle East and the capital is called Tel Aviv. I t was established and founded on May 14,1948 after the United Nations decided Jewish people needed a place to live after the Holocaust. Many of their homes in Europe had been destroyed or taken over by non-J ews . The religious population in Israel is about 75% Jewish, 16% Muslim, 2% Christian, and the rest belonging to minor religions like Druze and Samaritanism. The infancy of the country of Israel was mark ed by an event that has come to be known as the mass Palestinian graves. Dozens of Arab skeletons were collected south of Jaffa and all put into the same mass grave. These deaths occurred because of the fighting during the war in 1948. People tell stories of dead bodies lying on the street and being moved into these graves. Their skeletons were found and most showed signs of a violent death. Men women and children were often buried together without giving thought to their religious beliefs. These graves were found by accident during maintenance of the cemetery. During the time when Israel became a country, the Prime Minister was David-Ben Gurion. After this, forces from Lebanon, Syria, Iraq, Egypt, and Jordan invaded Israel to aid the Palestinians in their time of need, which began a war. During that war of Independence, about 6,000 Jews and 10,000 Palestinians were killed. The reason they were fighting was because they both felt as if something was being taken from them. To retalia te, the Intifadas took place. This was an uprising against the Jews by the Palestinians. One protest was in the 1980's and the other was in the early 2000's. The first Intifada was non-violent. It included large boycotts and Palestinians refusing to work jobs for Israeli people. Though the Palestinians were being peaceful, Israeli military forces responded with violence. In 2000, the failure of the two countries to achieve a peaceful resolution gave birth to the second intifada. Typically each country blamed the other for the onset of this conflict. The Palestinians gave up their peaceful behavior and began using tactics such as sniper fire and suicide bombings which Israel answered with a heavier attack. Before the conflict was finished, there were over 1,000 Israelis and 3,200 Palestinians killed. The Six Day War took place from June 5,1967 to June 10,1967. The war began when the Arab countries began plotting against Israel. After the Israeli representative gave a speech at the Un ited Nations detailing the ways in which they wanted to make a deal with the Arab countries, the representative from Egypt went on to say that the Israeli government was trying to deceive the rest of the world by claiming to deal diplomatically when in fact they saw it as an underhanded way to fool the rest of the world. Events like this were the catalyst to the beginning of the Six Day War. After the failure of any diplomatic attempt, there was no recourse except to go to war. The very well trained and organized Israeli armed forces made short work of the disorganized Arab forces. After the Israelis learned they were going to be attacked, on day one of the war the Israeli air force took out Egypt's air force before it was able to take off. Not only did they attack Egypt, but also Syrian, Iraqi, and Jordanian air forces until they gained air supremacy. On day two, heavy combat ensued between Israeli and Jordanian troops in the West Bank and Jerusalem. By the third day, Israel had ta ken over
