Earth Before Life After reading the article “Earth before Life,” the concepts that were addressed in the featured segment were how the atmosphere was developed and how the earth was formed. These concepts addressed the beginning of evolution and the adjustments to its surrounding. The article states “Chemical reactions and Physical processes on the early Earth created an environment that made life possible. And life, once it began, transformed the planet’s chemistry. Biological and geologic histories are inseparable.” Earth, a giant ball of hot gases, rocks and dust, went through a period of catastrophic and intense formation approximately 4.5 billon years ago. This was caused by particles of gases being drawn together and compressed, giving off a large amount of heat. Finally the earth cooled down enough for water vapor to condense and form liquid water. Rain fell from the sky for millions of years and covered most of the Earth with oceans and lakes. The oceans contained chemicals called nucleotides and amino acids that existed in little blobs surrounded by a membrane. These blobs are called microspheres and were not real cells but they were able to replicate themselves and reproduce. Energy from the sun and from lightning produced chemical reactions in the air that formed very complex molecules like nucleotides and amino acids. These are the building blocks of DNA (genes). Later pressure and heat

in its center pushed up solid portions of the earth that became land forms. Sometimes the land would sink back down and other portions arise. Earth before life was completely different from what humankind knows today. The volcanic activity, lighting, and radiation were more severe, it was inhabitable. The atmospheres development helped in making the world what it is today. The torrential rains cooled the earth’s early atmospheric surface and later formed lakes, seas and oceans. This formation provided the earth with various sea animals like fish and sharks as well as plants. Trees are the earth's most useful products of nature. Trees have been important to mankind's survival. The oxygen that is breathed is released by trees and other plants. Trees provide food, shelter, and material for animals and man. Gas is taken from inside the ground and is used in almost everyday life when we use our cars. Another example would be medicine; we get certain medicines from plants. Everything that we use in our daily lives is here because of our atmosphere and earth.Air pollution can affect ones health in many ways. Air pollution can result in long-term and short term effects. The short term effects of pollution can cause irritation of the eyes, upper respiratory infections of the nose and throat which can lead to bronchitis and pneumonia, headaches, allergic reactions and nausea. Short term pollution can intensify the medical conditions of individuals who have asthma and emphysema. Some of the long-term effects of pollution are lung cancer, respiratory disease, heart disease and damages to the brain, nerves, kidney and liver. Continuous exposure of air pollution can affect the lungs. When the sun is hot, emissions from car engines, factories, garden equipment and gasoline evaporation causes chemicals react with heat and sunlight to form ozone. Ozone pollution can cause inflammation and irritate the lungs. This can be a problem for those who have respiratory problems. Everyone stands a chance at being effected by the pollution which the earth contains. When unwanted wastes are burned and exposure to illegal dumping, the earth’s atmosphere can have an ever lasting effect due to the flames from the fire becoming hazardous to ones health when breathed in.Air pollution can possibly harm populations in ways so subtle that they have not been detected. Research is under way to look at the long-term effects of chronic exposure to low levels of air pollution, what majority of people experience as well as to determine how air pollutants interact with one another in the body and with physical factors. A few examples are nutrition, stress, alcohol, cigarette smoking, and common medicine. Another investigation is the relationship of air pollution to cancer, birth defects and genetic mutations. Results of air pollution are seasonal “holes” in the ozone layers in the atmosphere above the Artic and the Antarctica, are coupled with evidence of the ozone depletion. When one experience events of this magnitude, it increases the amount of ultraviolet radiation intended to reach the earth, where it damages plants and crops and can lead to cataracts and skin cancer. This downwardness has been caused by the emission of chlorofluorocarbons from air conditions, aerosols and refrigerators.As an advert runner and trainer, the concepts played a significant role because one would have to conclude that running in the morning is ideal, because of the combustion from the gasoline and other fuels in automobiles, airplanes and trucks produced various other pollutants: such as gaseous hydrocarbon, carbon monoxide and other quantities of particles. If one decides to run during the evening, this could have an effect on individuals. In the presence of sunlight; one must be aware that sun light contains nitrogen oxides combine with hydrocarbons forms a secondary class of pollutants, known as the photochemical oxidants. Therefore, when these chemicals are exposed to his or her lungs it could have an everlasting effect on the body.Earth’s evolution is the relationship among the concepts addressed. All things were formed through this very complex, ever changing process. The word evolution also refers to the formation and development of life on the earth. The belief that says all living thing were formed from non living matter and changed throughout the years. This theory says that the first single celled organisms just showed up about three or four years ago. As time passed more complicated organisms started to appear with which had characteristics to help them adapt to their environment. Throughout the ages the species that are known today where produced. The theory of evolution helps to explain two main facts of nature, the huge variety of organisms on the earth and their basic similarities. Scientists believe that more than two million species of living things inhabit the earth. But these things share certain characteristics with each other. Such as there cell structure or genetic code. According to the theory of evolution variations among species are mainly based on an organism’s adaptation to a certain environment. All though the theory of evolution is supported by allot of scientific evidence, evolution is not accepted by everyone. Some believe in the biblical theory of the New Earth creationists of how the earth, its life forms, and the rest of the universe were created by God during a six day, 144 hour, interval, fewer than 10,000 years ago. The Old Earth creationists believe that geology and radiometric dating has shown that the world is billions of years old. They believe that God created the Earth itself, the earth's life forms, and the rest of the universe at that time. The Scientific views of the origin of the universe occurred about 15 billion years ago. The earth coalesced about 4.5 billion years ago. Life subsequently began, probably as bacteria deep in rocks, and has been evolving ever since. These various processes have been driven by purely natural forces, without input from God.
