Earth : The Only Frontier

Aliens and life beyond earth has been a mystery for a long time. Many people and scientist have been looking for life outside of Earth, or just floating in the sky trying to get video of it. For all of human history we have been looking for extraterrestrial life, and these are the major events of finding, debunking, and moving forward to life on earth

Even though we separated ourselves from nature in the attempt to salvage some beauty in the world we still “began to alter places where we were not,” through by-products of our industrialized society. (Mckibben XX) Mckibben says “it is also true that we are apart of nature” (Mckibben XXI) while Cronon wants us to see that “wilderness is more a state of mind than a fact of nature.” (Cronon 493) While Cronon wants humans to separate themselves from the wild, Mckibben asks us to confront nature head on. We are apart of it and“we possess the possibility of self-restraint” so we still have the means to stop abusing the natural order. In order to do this “we would need to change the ways we move ourselves around, the spaces we live in, the jobs we perform.” (Mckibben XXII) We can start by thinking of practical ways to affect the environment positively, starting in the

James Green discusses in his speech the possibility of there being life beyond earth. Green starts off with a quote that is used in a lot of movies, books and television shows, “Is there life beyond earth in our solar system?” He follows this initial quote with one by Carl Sagan, an American astronomer, “It takes extraordinary evidence for extraordinary claims.” It is important for Green to use these two quotes as attention getters. He hooks the listener with his works and we begin to think if there really is life in our solar system then just on earth.

At present, we consider ourselves living in a modern society with big cities and advanced technologies. New innovations allow us to transport and connect around the globe quickly. Human have more opportunities to interact, communicate and develop. The American life we live is such a happy picture drawn by ourselves, by the American Dream. But as a natural reaction, with those delightful and colorful layers on the top, we tend to forget the backdrop of our picture. We forget the foundation of that living picture, the origin that shaped the American being and characteristics. One of them is the frontier. Frederick Jackson Turner, a famous historian from the University of Wisconsin advanced his frontier

Justice to future generations requires us to pass along the beauty and bounty of Earth diminished. Our politics, economy, and media betray an almost infantile fixation on the present moment, seeking or selling instant gratification, oblivious to history. We need to develop a culture worthy or adults, one that recognizes our actions have consequences. If we take more than we need from the riches of the planet, if we drain aquifers, squander topsoil, or fish the seas bare, we are stealing from our children. If we fill dumps with toxic waste, fill barrels with radioactive debris, spew poisons into the atmosphere and oceans, we will leave our descendants a legacy of grief. Conservation aims to avoid causing harm to our children, or their children, or to any children ever” (Sanders

Extraterrestrial life has been a big topic for Americans since day one. According to author Lee Speigel there is an estimation of 48 percent of Americans throughout the nation that believe in life on other planets while only 35 percent reject the idea. Life on other planets exists. According to the article “Aliens among Us” by Paul, David extraterrestrial evidence has already been discovered such as different types of bacteria and even water. The article “Aliens among Us” is a credible source because it has many explanations and possibilities on how life on other planets can easily be real. Extraterrestrial life can be many things such as plants or living bacteria. Astronomers have proven that there is water in other planets such as Mars. Water contains different types of bacteria and cells, water in other planets can be one of our best piece of evidence that we can prove that there is life on other planets. There has been UFO’s crashes that have been recorded such as in Roswell, New Mexico 1947 but the government took all the evidence and it’s probably in Area 51. Although there is no hard evidence that proves aliens are real, NASA has announced that they will be able to find living creatures by the year 2025.

"Save the Planet," "Reduce, Reuse, Recycle," "Go Green." Quotes like these have become a commonality in today's age. We all are familiar with the large efforts to help preserve the environment. In "Ideals of Human Excellence and Preserving Natural Environments," Thomas E. Hill Jr. sums up his essay by stating, "The point is not to insinuate that all anti-environmentalists are defective, but to see that those who value such traits as humility, gratitude, and sensitivity to others have reason to promote the love of nature" (688; par. 4) This excerpt provides the thesis behind Hill's argument. The author found that

it was discovered that there are other planets like Earth out there that are able to accommodate life forms like our planet. And it is highly unlikely that we are the only living things out there in the big universe

Most astronomers and scientists seem firmly convinced of this fact. Although there is not any direct (or even indirect) evidence to support these claims that other sentient life is sharing the universe with us. However, this lack of evidence showing that extraterrestrial life forms exist is not proof that they do not exist. It just does not seem logical that our planet is the only place where life and intelligence could have developed. The odds are billions against life of some form being unique to the Earth only. The Earth is unimportant in the grand scale of things in the galaxy. By this I am referring to its' size and position in the universe. In fact, the American Association for the Advancement of Science suggests that the true question that we should be

Long ago, people depended on nature for shelter, food, and survival. However, as time goes on, new inventions develop, and society improved except nature which humans still depend on for survival. Some people today think that nature is not important, or at least not as important as their phone or computer. Humans understand that food comes from plants and animals and paper from trees, but they do not reflect on how much they take from nature compared to the small actions they take to give back. Emily Bronte's “Shall Earth No More Inspire Thee”, Jack London's “To Build a Fire” and Jon Krakauer's Into The Wild all display the very weak relationship between man and nature because humans no longer feel dependent on nature.

There are so many ways living organisms like our selfs (Human beings) rely on the atmosphere. It is one of the key reasons why there is life on earth to begin with. Here are some reasons on why we as living organism alongside many other living organism rely on the atmosphere. First off the atmosphere provides us with oxygen which is what we need to breathe and keep our bodies working. Without the atmosphere we and many other living organisms would die or not even be alive to begin with. Just try and hold your breathe for a couple of seconds, you can't because your body needs oxygen and will force you to open your mouth and get the oxygen your body needs in order to work correctly. Also, the atmosphere acts as a shield against radiation that

Helium makes up about 0.0005% of the earth's atmosphere. This trace amount of helium is not gravitationally bound to the earth and is constantly lost to space. The earth's atmospheric

The argument suggesting life existing on other Earth-like planets has been present since man first looked into space and questioned his own existence and the existence of others like him. Today there are many theories on the existence of intelligent life elsewhere in the universe, but only one theory goes beyond them and into an even larger realm. The contents of this theory, known as the “multiverse” theory, suggest that humans on Earth live within one universe of many others that reside within a primordial vacuum containing many other universes (Jenkins and Perez). Each of these universes possesses potentially different natural constants and physical laws that govern them differently, thus calling forth some logical questions. First,

For centuries, there has been speculation about life outside of Earth. We often see reports of UFOs that cannot be explained. The size of the universe is unfathomable. It is almost impossible for a human mind to grasp the vastness of the universe. Our universe is continually expanding so that even if we could grasp how big it is it would be larger than what we had just realized. There are several scientific theories that suggest there may be multiple universes. It is very possible that there is an outside light. Reporting from inquire is looked at in America as false and fake. However, there are so many things we do not know about because we as people refuse to believe it.

Earth is the only planet in the solar system known to harbour life. Our planet 's rapid spin and molten nickel-iron core give rise to an extensive magnetic field, which, along with the atmosphere, shields us from nearly all of the harmful radiation coming from the Sun and other stars. Earth 's atmosphere protects us from meteors, most of which burn up before they can strike the surface. Nitrogen and Oxygen are the predominant gases in the atmosphere, accounting for about 99 percent of dry air. While 1 percent is mixture of all other gases make up the remaining 1 percent. All the gases found in the atmosphere are natural except CFCs (invented by Thomas Midgley, Jr. was an American mechanical engineer and chemist).
