The Basics of the Blue Dot and Preservation
The earth has been in discussion since the beginning of man. Questions of flat or round, does the earth orbit the sun or is the earth the center of the universe, and how did life start? As humans use the finite resources of the earth, many scientists are struggling to find the answer and what effect the inhabitants have on the planet.
Our solar system is made up of the eight planets, the Sun, dwarf planets, and over a hundred satellites planets. Included in our solar system is also many comets and asteroids. The planets orbits in ellipse formation with the Sun as the center point. Most of the planets travel in an almost perfect circle, except for Mercury. The planets orbit almost on the same plane with plane earth, called the ecliptic. The ecliptic is approximately only seven degrees of incline from the sun’s equator.According to Arnett (2015) website, All planets “orbit in the same direction (counter-clockwise looking down from above the Sun’s north pole); all but Venus, Uranus and Pluto also rotate in that same sense” (Orbits, para. 1).
When the earth was young, there was a major collision with another planet causing a direct impact with the earth. The colliding world was destroyed, and almost took the planet earth with it. According to Case Western Reserve University (2006), “The planet was coming in with such force that when it was destroyed, the molten iron in its core continued to travel through Earth, to eventually be included it its core” (Creation, para. 3). The collision theory would also explain the moon’s small iron content. When the explosion from the impact happened, rock and debris were sent out into the galaxy. Over the years, the debris formed the moon. This action also contributed to the moon’s rotation and accounted for the moon’s day as precisely being the same as its year.
Current scientific studies, records and studies Plate tectonics theory. Scientist sees the approach as more of, fact as time continues and details become discovered. A Scientist is careful with this method to not indulge in personal belief, to make sure it is truly fact.
According to Duckeck (2015), “In science, especially if it is a descriptive science which tries to explore nature, it is a good idea to be careful and keep in mind the difference between facts and theories. Still, plate tectonics are the most important theory in geology and – after half a century of scientific research in this field – a very well supported one.” (Plate Tectonics, para. 2).
The Ocean Floor
According to Alden, A. (2015), “The crust is not the same thing as the plates of plate tectonics. Plates are thicker than the crust and consist of the crust and the shallow mantle just beneath it; the combination is stiff and brittle and is called the lithosphere” (Crusts and Plates).
Three types of Tectonic Plate boundaries are present on earth. The first of them would be divergent boundaries. With a divergent boundary, the plates are pulling apart from each other. Rifts or separation when on land will eventually arise; as this happens the area will break apart and fill in with water. Then countries like Iceland currently as one land mass will have many defined land masses. In converging boundaries, the plates collide into each other. In a converging boundary, the crust is destroyed under immense pressure of the collision and recycled back into mantel as one plate is driven under the other plate. Converging boundaries is also what gives shape to mountains and volcanoes throughout earth. On earth, there are three types of converging boundaries, the Oceanic-Continental Convergence, Oceanic-Oceanic Convergence, and Continental-Continental Convergence. Another type of boundary is the Transform-Fault Boundaries, where two plates are sliding horizontally past each other. Each boundary described uses an extreme amount of energy when unleashed causes tremors that change the earth’s surface. Some believe the plates are moving at relatively different speeds and independently of one another. Realistically each of the tectonic plates is moving in a manner, which is interconnected. As one plate moves, the other plates are affected in one way or the other. Many miles away the signs of change can be noticed as each plate must react cohesively with the movement of another plate. Scientist study this in the Atlantic Ocean as the African plate moves away from the South American plate, the seafloor grows larger. Thousands of miles away in the Pacific Ocean, the sea floor area is shrinking as the floor is being consumed in deep trenches.
Natural events: the New Madrid Seismic Zone
According to the Forte (2007) website “localization arises because of structural variability in the Farallon slab and the low viscosity of the sub-lithospheric upper mantle, and it represents a heretofore unrecognized and possibly significant driving mechanism for the enigmatic intraplate seismicity” (Descent of the ancient Farallon slab drives localized mantle flow below the New Madrid seismic zone).
According to Nielsen, O.H. (2015), “central part of the Farallon Plate completely subducted under the southwestern part of the North American Plate. Around 23 million years ago, the remnant of the Farallon Plate split into the Juan de Fuca Plate subducting under the northern part of the North American Plate, the Cocos Plate subducting under Central America and the Nazca Plate subducting under the South American Plate” (para. 1).
The New Madrid Seismic Zone is a unique on earth, where so many traumas from many areas of land and ocean have affected one small place. Billions of years in design, the world waits for The New Madrid Seismic Zone to become a huge sinkhole. Today scientist describes future events in this rejoin would be catastrophic. The great rise and sink of the Ozarks in 1812 is nothing to what could be waiting for mankind in the near future.
Compare and contrast
Continental drift is a theory based on parts of the earth’s crust moves on the earth’s liquid core. This theory is very plausible based on fossil records. Tectonic plates are another theory, which suggests continents move about from one area to another colliding, separating, and rubbing together. This activity creates our ocean floors, mountains, and islands. As void forms, mantel fills the area. As voids close up, plates disappear, and mountains form. Both theories work together like a living puzzle.
As discussed earlier, the African plate moves away from the South American plate placing pressure on the east side of the North American plate through movement. The plate’s movement has caused the ocean floor to become larger. On the other end of the North American plate, the ocean floor is shrinking as an ancient plate disappears under the North American plate. The movement has caused more stress in an already weakened part of the crust in the middle of the North American plate, causing Earthquakes in the Ozarks.
Many people believe water is easy to obtain because most of the world’s surface is comprised of water. The difference between freshwater and seawater is evident, from the salty taste. Most of the water on the earth’s surface is the sea water. As the population grows throughout the world, the need for more fresh drinking water has become hard to obtain.
Chemical and physical properties of water
According to Encyclopedia Britannica (2015), “Concentrations of phosphorus and nitrogen are generally low in the photic zone because they are rapidly taken up by marine organisms. The highest concentrations of these nutrients generally are found below 500 meters, a result of the decay of organisms (Physical and chemical properties of seawater)”.
Seawater to fresh water
According to Raunekk (2015), “Generally water is boiled at 100 degree Celsius, but in freshwater generator it is done at around 60-70 degree Celsius. For this purpose, educators or air ejectors are use. Eductors reduces the chamber’s pressure to such a point that water starts boiling at a temperature of 60-70 degrees Celsius (Single stage fresh water generator)”.
A greener way to make fresh water is by using a hydrologic cycle. Like a solar panel or solar water heater, the use of sun can make free fresh water. This type of method is not efficient, but for a desperate need or just personal use; it is seen as a viable system. Placing a metal tray filled with water under a transparent panel, and then sealed over a bigger tray, the system is built and ready to go. Place the solar distiller in direct sunlight. As the sun heats the distiller, the water will accumulate on the inner side of the transparent panel. As more water collects, the water will collect on the outer edge and start running down the sides of the bigger pan. The result will leave behind salt deposits in the inner pan and fresh water in the outer larger pan. Solar distillers are growing in popularity in the United States southwest region. According to Donahue (2015), “Solar distillers are also “gaining popularity as a survival tool in Third World countries where fuel is expensive and water treatment options are few (Solar Water Distillation)”.
Globalization and Finite
Many people think the world’s natural resources are never ending. In reality, everything must come to an end, as the saying goes. When concerning natural resources, the statement is all so true. Politicians throughout the world are arguing if the earth’s natural resources will end or is it a myth. Despite years of research saying, the resources will end. Some people religiously believe the scientific data is wrong and will not end.
According to Agriculture and Consumer Protection (2015), Water is a finite resource: there are 1400 million cubic kilometers on earth, circulating through the hydrological cycle. Nearly all of this is salt water and most of the rest is frozen or underground. Only one-hundredth of 1 % of the world’s water is readily available for human use (Where is the water, para. 1).
Water is everywhere, and though there doesn’t seem to be a genuine end to water. Water is becoming more poisonous. As humans abuse the right to use and abuse water, people are finding through research; all life on earth suffers the abusive behaviors. Humans are demanding more meat, bigger automobiles, and more power to live a comfortable lifestyle. Livestock is the earth’s largest pollutant. The livestock industry not only is the greatest source of methane gas polluting the air supply, but also machines and transportation causes the higher use of petroleum products such as gas, rubber, and plastics. Researchers have found these products in our stream, co2 in the air from unburned gasses, but also in the ever-growing landfills where we bury our wrongdoings. Human life on earth cannot seem to understand if a person likes a clean the inside of their home, why it wouldn’t be important to clean the outdoors. Some people feel the need to discard their waste and garbage into the water. This type of ridiculous behavior pollutes our oceans and underground water sources. Co2 thickens our atmosphere trapping the sun’s rays between our earth and the atmosphere, causing higher temperatures. The higher temperatures cause extinctions on land and in the waters. With larger amounts of decay in earth’s waters, the aquatic life becomes ill from the lack oxygen in the water for the fish to breath. The modern traits of people are to detach their wasteful behavior by throwing out the unused, discarded products into the trash. The trash is just the beginning. Trash sooner or later is transported to a landfill somewhere usually outside the town to be buried and forgotten. As the methane gas of all the products decompose into the air, the chemicals leech into the ground waters commonly used for drinking water.
History of the problem
The earth was designed to sustain life. Life on earth has exceeded the earth’s capabilities. As the population grows, so does the demand of earth’s resources. In the twentieth century, the population growth spiked up for various reason. In the medical field, technology has made it possible for people to live longer. In the United States during the 1900s there were 17.2 deaths per thousand people annually. During 2005, the rate of deaths in the United States decreased to 8.2 deaths per thousand persons (Pearson Education, Inc., 2015). Birth rates per year also have steadily dropped. In 1910, there were 30.1 births per thousand persons in the United States. Birth rates decreased some until the 1950s with 24.1 births per thousand persons in the United States and continued through the 1960s with similar results. In 2005, the United States saw a steady drop in birth rates at approximately 14.0 per thousand people (Pearson Education, Inc., 2015). At first glance, it seems the population should be going down, but because of modern medicine the young people of the 1920s are still alive. The facts would suggest, every year there, may be less per thousand born, in reality there are more births than deaths and more people, in general, are born.
Current level of concern
Jaehnig (2015), A three-year study of 43 subwatersheds within the Lower Kaskaskia River basin has revealed that those in urban areas contain on a day-to-day basis significantly higher levels of both E. coli and phosphorus, a major fertilizer component, than do the largely rural, agricultural subwatersheds (Carbondale, ill., para. 2).
Within the Lower Kaskaskia River basin, 29 other watersheds in the countryside were also tested. The reports found the watersheds did have lower readings than those in the city, but in no way were they in good shape. Illinois is scrambling to find ways to deal with the issue. A similar case of this in Milwaukee wasn’t considered as early as Illinois problem. In 1993, high Cryptosporidium levels in Milwaukee’s drinking water supply sickened more than 400,000 residents. According to Natural resource defense council (2015), in 1996 the Centers for Disease Control established a link between spontaneous abortions and high nitrate levels in Indiana drinking water wells located close to feedlots (Livestock pollution and public health).
Governments around the world are now implementing incentives for free range farms and organic grown farms. These steps help not only lessen the use of chemicals spray on the grounds but also chemicals injected into the animals of commercial livestock. Governments around the world are also intervening with the use of chemicals at nature’s wetlands. According to Grinning Planet (2015), both inland and coastal wetlands act to buffer surges in runoff and to filter pollutants from runoff and flows (Reducing Nutrient and Pesticide Pollution, para. 5). Local governments are taking steps by offering roadside recycle pick-up and installing sewer drains that let people know not to dump because it runs off to their local lake, stream, or ocean.
