Changing Our Atmosphere

Our Changing Atmosphere

Energy from the sun drives the earth?s weather and climate, and heats the earth?s surface; in turn, the earth radiates energy back into space. Atmospheric greenhouse gases (water vapor, carbon dioxide, and other gases) trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse.

Without this natural greenhouse effect, temperatures would be much lower than they are now, and life as known today would not be possible. Instead, thanks to greenhouse gases, the earth?s average temperature is a more hospitable 60?°F. However, problems may arise when the atmospheric concentration of greenhouse gases increases.
Since the beginning of the industrial revolution, atmospheric concentrations of carbon dioxide have increased nearly 30%, methane concentrations have more than doubled, and nitrous oxide concentrations have risen by about 15%. These increases have enhanced the heat-trapping capability of the earth?s atmosphere. Sulfate aerosols, a common air pollutant, cool the atmosphere by reflecting light back into space; however, sulfates are short-lived in the atmosphere and vary regionally.

Events Leading Upto The Bombing Of Hiroshima

Events Leading Upto The Bombing Of Hiroshima

On the 2nd of August 1939, scientists wrote to President Roosevelt telling him of efforts in Germany to purify Uranium 235, which could be used to make an atomic bomb. Roosevelt then set up an ?Uranium Committee? to research into an atom bomb. Once the United States entered the war, this situation changed dramatically. Scientists working in Britain had discovered how to control an atomic explosion. This was a very important step to making the bomb, and the British gave their knowledge to the Americans. In December 1942, President Roosevelt began the Manhattan Project.
The Manhattan Project was a group of top nuclear scientists who were to find out how to make an atomic bomb. This group of scientists was under the command of General Leslie Groves, and Robert Oppenheimer. The project took place in many places across the United States, but mainly in Los Alamos, New Mexico. Los Alamos was a small town consisting of a school and a few homes. This was bought up by the U.S. government, and made into a secret city that would eventually house 6,000 people. This was a very secretive time and the scientists didn?t enjoy their surroundings very much.

Peekskill

Peekskill

Peekskill
The glorious views of Hudson Highlands from the City of Peekskill call attention to its strong relationship with the history of the nation. The city of Peekskill, located in Westchester, New York, lies right on the Hudson River. It was settled in 1665, and slowly grew over the next couple of centuries to become a city by 1940. Peekskill has many clothing, leather goods, lighting fixtures, and office equipment that are made there. In the American Revolution, Peekskill was attacked and burned in 1777 by the British. After the war the city became a prominent trade center.. George Washington considered the area a strategic key to defense of the nation. He established headquarters at the Birdsall House and there, against his better judgment, signed Benedict Arnold?s command of West Point. Peekskill was razed twice by the British during the Revolutionary War, and some of the notable sites from that period can still be identified today.
According to www.hudsonriver.com/rivertowns/peekskill.htm, from the late 1600?s, when Jan Peeck established a trading post on Annsville Creek, Peekskill relied on the Hudson River for its business needs. During the 19th century it became a manufacturing center for stoves, hats, and even underwear. Boats of all

Ways Of Abortion

Ways Of Abortion

Ways of Abortion

From Below

Menstrual extraction
A very early suction abortion, often done before the pregnancy test is positive.

Suction
The abortionist first paralyzes the cervix (womb opening). He then inserts a hollow plastic tube with a knife-like tip into the uterus. The tube is connected to a powerful pump with a suction force 29 times more powerful than a home vacuum cleaner. The procedure tears the babys body into pieces and the hose frequently jerks as pieces of the baby become lodged. The placenta is then cut from the inner wall of the uterus and the scraps are sucked out into a bottle.
Dilatation & Curettage (D&C)
Uncommon today and used during the first 10 weeks of pregnancy. This is similar to the suction procedure except that the abortionist inserts a curette, a loop-shaped steel knife up into the uterus. He then cuts the placenta and baby into pieces and scrapes them out into a basin. Bleeding is usually profuse.
D & X (Partial Birth)
Also used for advanced pregnancies. The cervix is dilated to allow passage of a ring forceps. A foot or lower leg is located and pulled into the vagina. The

Europeanization Of Latin America In The 19th Century

Europeanization Of Latin America In The 19th Century

In nineteenth century Latin America, outside influences such as the United States, Great Britain, and France all had major impacts on the development and progression of Latin American countries. The Latin American countries looked to Europe as well as the United States as the model for a way of living. They attempted to recreate in their nations and states what they saw as everyday living in Europe and the United States. They modeled their style of dress, architecture, and modern technology around these European ideas.
Latin American countries modeled the ?acceptable? style of dress after the same fashion they saw Europeans wearing at the time. The elite members of society, whether they were of European descent or not, took Europe?s style of dress with them when they settled into Latin American land. The typical clothes one would wear if he was an elite member of society were the frock coat, the nice looking white dress shirt, the black pants, and large boots. Although most citizens who wore these clothes were people who came from European descent, there were indigenous people who adopted the European way of life and shunned their old ways. One

Australia?s Prime Minister to act against terrorist neighbors

On December 1, 2002 Australia?s Prime Minister John Howard said that he is prepared to act against any terrorists in neighboring Asian countries and that the international law and the U.N. Charter should be changed to empower nations to strike in defense against terrorists who plan to attack them. Today Australia has one of the most powerful militaries in its region, which include a modified air force and phenomenal Special Forces. The main reason for Howard?s comments come as Australians wait nervously and watch how Southeast Asian countries to its north deal with Islamic militants in the wake of the October 12th bombings on Indonesia?s resort island of Bali. The devastating attack left almost 200 people dead and close to half of them Australian tourists.
The people that have been blamed for the terrorist attacks are none other than the al Qaeda group led by Jemaah Islamiyah. Dozens of members of the al Qaeda group have been arrested and jailed but many more are still believed to be operational. Since the attacks the Australian government has increased security measures at their embassies overseas and have warned the people

? There were many musical sources that made up rock and roll. In fact most and if not all the ?artists who could have been considered rock and musicians prior to 1955? were black except for Bill Haley and his comets. We first have saxophone which was made famous as a rock and roll instrument by ?Jackie Brenston?s solo on Rocket 88?. The electric blues guitar was introduced by T-Bone Walkers? ?Call It Stormy Monday?, and later perfected by Chuck Berry. Professor Longhair brought the piano into the rock and roll scene by playing a mix of ?offbeat Spanish beats and Calypso down beats.

As for vocals go, they came mostly from rhythm and blues performers such as ?Joe Turner, Ruth Brown, LaVern Baker.? Ray Browns? vocal talents also influenced Little Richard and Ray Charles.

? There were a few factors that led to the independent record labels being able to compete with the major labels. First was that fact that major labels assumed that audiences would always ?respond favorably to gentle changes in popular styles.? The introduction of rock and roll threw this assumption out the window. Another factor that helped this was the introduction of ?poorly

Vegetarianism

Vegetarianism

?You know, it?s shocking how much violence goes on in our civilized world.? my mother says as she bites into a cheeseburger. Believe it or not, that cheeseburger is a direct product of uncivilized violence, a cause that hundreds of millions of Americans support every day. The meat industry kills nine billion animals every year and contributes to extensive deforestation and pollution. It causes everything from heart disease to breast cancer in millions of people worldwide. Vegetarianism is the best way to save animals? lives, to help the environment, and to achieve optimum health.
There are strong health, environmental, and ethical reasons for choosing a vegetarian diet, while the reasons against are habit and convenience. When you think of the consequences of eating animal products in today?s society, it seems that vegetarianism is the prudent choice. (Stepatnik 28) Seven percent of Americans are vegetarians, they do not eat any meat; .5 percent of Americans are strict vegetarians – vegans – eating no animal products whatsoever. This paper is an introduction to why choosing a vegetarian lifestyle is essential for protecting animals, the environment, and personal health.

Eurocentrism

Eurocentrism

In historian Lynn White?s book, Medivieval Technology and Culture Change, he argues that various technological advances within the field of agriculture related directly to monumental social, economic, and cultural changes of Europe. Therefore, these technological advances and innovations led directly to Europe?s rise to capitalism in modern times. White supports his theory by way of technological determinism, or the claim that new technology is the primary cause of change, regardless of where the technology came from. While technological advances and innovations are valued highly in societal, economic, and cultural changes it is important to understand both how the technology reached Europe, as well as other facets of change that may have contributed to Europe?s rise to power.
In White?s book, he specifically sites the importance of the heavy plow, horse collar, and use of horse power as key innovations that led directly to Europe?s rise to power. However, what he fails to take into consideration as Blaut comments in his critique is the origins of these innovations as well as the geography of Europe during this time (pg. 34). Sadly, none of these criteria are taken into consideration given the entire support for his argument is

O Pioneers

O Pioneers

During the middle to late 1800?s, thousands upon thousands of Americans, as well as foreigners, flocked to the mid-western part of the United States. They flocked to this area hoping to gain free or cheap land promised to them by the United States Government. Most of the ?pioneers? left cities and factory jobs to venture out into the American prairies and become farmers. They left their homes, not only because the land was either free or cheap, but also because they wanted to leave the hardships of city life. However, as most would find out, prairie life had its? share of hardships, that far out-reached the hardships of city life. Among these hardships were the death of siblings and friends due to starvation and/or hard work. Pioneers also had to face the stresses and burdens of trying to make a living off of the land. Along with these stress?s, they had to worry about how to make money off of the land. All of these hardships, as well as others, were portrayed in Willa Cather?s ?O? Pioneers?.
