Crude Oil and Week Three Tapped Movies

Crude Oil and Week Three Tapped Movies Introduction Environment refers to the sum total of the conditions that surround people and other living organisms. The thriving or survival of many organisms, including human beings, depends on the conditions of the environment. A poorly conserved environment presents great hazards to its inhabitants. However, if well conserved, environment gives invaluable benefits to those it supports.

This essay focuses on efforts that the Crude Oil film and Week Three Tapped movie apply to sensitize the population about environmen tal conservation. The Crude Oil Film Summary Directed by Wang Bing, the Crude Oil movie is a documentary whose main theme revolves around the need to conserve the environment. To conserve the environment, the documentary advocates for the urgent need to prevent pollution of the environmental resources. In particular, the movie focuses on pollution that most companies and renowned corporations cause in quest for energy. It gives the Ecuadonian Amazon (rainforest Chernobil) as one of the natural resources that large organizations have destroyed in the pursuit for energy. It seeks to inform such companies and organizations of the dangers of using crude oil as energy sources without coming up with measures aimed at preventing pollution to the natural oil resources. Through this movie, Wang Bing argues that if the current trend continues for a considerably long period, then a major crisis is inevitable. The environment will not be habitable, which will make life and living unbearable. Therefore, those who are sensitive towards the environment should not only make direct efforts to conserve it, but also sensitize the rest of the world about the need to conserve it. Opinion I vehemently agree with what Wang Bing is trying to put across through his documentary. It does not require much conviction for one to realize that the modern society faces a major crisis emanating from the wanton depletion of natural resources for short-term benefits such as production of energy.

Therefore, the natural resources are becoming insufficient and the situation worsens by the day. In order to avoid the looming e nvironmental crisis, individuals and organization have to observe strict measures during the use of natural resources to prevent pollution and unnecessary depletion. Besides, there should also be efforts to use alternative sources of energy to avoid overdependence on crude oil whose exploitation leads to environmental destruction. In addition, governments should protect natural resources like the Ecuadonian Amazon by imposing strict guidelines on companies using coal products as their sources of energy. As a result, the environment and its resources would be able to sustain the needs of the current generation and generations to come. Week 3 Tapped Summary The director of the movie, Week 3 Tapped, seeks to sensitize the world about the harmful effects of using crude oil and its products as the main source of energy. The movie also awakens the audience about the potential harm that bottled water has on human health. It focuses on companies for example Nestle and Coca-Cola that obtain water on a free basis and sell it to people after cleaning it. Clean water forms only 1% of the earth’s surface but due to the exploitation of crude oil resources, some of the harmful substances contained in the crude oil find their way to water resources. PET, for example refers to a chemical substance called parazyline from crude oil and this chemical normally finds its way to water products such as coke, dasani and nestle. In addition, PET contaminates air, soil and underground water. Therefore, the director of this movie suggests that the exploitation of crude oil results in contamination of natural water resources, which is a constituent of many consumable liquid products. The director further reveals that the immediate effects of these chemicals on the human body are minute and initially unnoticeable; however, these minute amounts accumulate and harm the body after considerable period. Therefore, it is important that governments be aware of the potential effects tha t the exploitation of crude oil has on human health.

Oil has even attracted wars, for example, the Iraq hinges on the desire by nations to control oil reserves as a means of gaining power. People around the world therefore need to halt the exploitation of oil resources and adapt alternative energy sources. Opinion I concur with the message that the director of this movie sends to the audience. First, it is worthy to note that indeed, oil as a source of energy has forced nations to scramble for power. America, for example, has in the past tried to control the oil rich Iraq, which ended up in war. The Bush administration fostered good relations with oil companies to control this rare resource. If things stay unch anged, then a major global crisis is imminent. The demand for oil will escalate to supersede the supply and the world will plunge into uncalled crisis. Consequently, prices for the little available oil will shoot up making it affordable for only the rich people in the society. The future generation will suffer greatly since an energy crisis usually affects all sectors of the economy. People will not be able to afford basic commodities and industries that depend on oil as the main source of energy for example air transport will stall resulting into a global crisis. Indeed, there is need to seek alternative sources of energy other than oil. Conclusion The use of crude oil as a source of energy has become a common practice in the modern world. The reason behind this trend is population increase and emergence of many industries. Overdependence on crude oil as a source of energy has led to energy crisis due to high demand and limited supply. The exploitation of this energy resource has also led to the degradation of the environment. Some harmful chemicals present in crude oil find their way to consumable resources like water. Unfortunately, such chemicals are known to affect the health of the human beings negatively. If nations continue depleting crude oil resources for energy production, then a global energy crisis is imminent. Therefore, there is a dire need to sensitize governments to put stern measures that either restrict exploitation of oil reserves, or ensure that people take important measures that seek to conserve the environment and protect human health.Advertising Looking for essay on environmental studies?

History of Microscopes

History of Microscopes A microscope  is an instrument for viewing objects that are too small to be seen easily by the naked eye. There are many types of microscopes. The most common is the  optical microscope, which uses  light  to image the sample. Other major types of microscopes are the  electron microscope, the  ultramicroscope and the various types of  scanning probe microscope. Early Years Circa 1000 AD: The first vision aid was invented (inventor unknown)  and was called a reading stone. It was a glass sphere that magnified when laid on top of reading materials.Circa 1284: Italian inventor  Salvino DArmate is credited with inventing the first wearable eyeglasses.1590: Two Dutch eyeglass makers, Zaccharias Janssen, and son Hans Janssen experimented with multiple lenses placed in a tube. The Janssens observed that objects viewed in front of the tube appeared greatly enlarged, creating both the forerunner of the compound microscope and the telescope.1665: English physicist  Robert Hooke looked at a sliver of cork through a microscope lens and noticed some pores or cells in it.1674: Anton van Leeuwenhoek built a simple microscope with only one lens to examine blood, yeast, insects and many other tiny objects. Leeuwenhoek was the first person to describe bacteria  and he invented new methods for grinding and polishing microscope lenses that allowed for curvatures p roviding magnifications of up to 270 diameters, the best available lenses at that time. 1800s 18th century: Technical innovations improved microscopes, leading to microscopy becoming popular among scientists. Lenses combining two types of glass reduced the chromatic effect, the disturbing halos resulting from differences in refraction of light.1830: Joseph Jackson Lister reduces spherical aberration or the chromatic effect by showing that several weak lenses used together at certain distances provided good magnification without blurring the image. This was the prototype for the compound microscope.1872: Ernst Abbe, then research director of the Zeiss Optical Works, wrote a mathematical formula called the Abbe Sine Condition. His formula provided calculations that allowed for the maximum resolution in microscopes possible. 1900s 1903: Richard Zsigmondy developed the ultramicroscope capable of studying  objects below the wavelength of light. He won the Nobel Prize in Chemistry in 1925.1932: Frits Zernike invented the phase-contrast microscope that allowed for the study of colorless and transparent biological materials for which he won the Nobel Prize in Physics in 1953.1931: Ernst Ruska co-invented the electron microscope for which he won the Nobel Prize in Physics in 1986. An electron microscope depends on electrons rather than light to view an object.  Electrons are speeded up in a vacuum until their wavelength is extremely short, only one hundred-thousandth that of white light. Electron microscopes make it possible to view objects as small as the diameter of an atom.1981: Gerd Binnig and Heinrich Rohrer invented the scanning tunneling microscope that gives three-dimensional images of objects down to the atomic level. Binnig and Rohrer won the Nobel Prize in Physics in 1986. The powerful scanning tunnel ing microscope is one of the strongest microscopes to date.
