...People living in Africa are usually living in the Saharan Region. Sometimes, this region could be very hot, dry, and unforgiving. The Sahara is the largest desert in the world, and it is still growing due to poor farming techniques and little water and rain. This essay will be about how people have managed to adapt and thrive in conditions such as these, focusing on the Sahel, Oasis, and Desert environments of the Sahara. Many adaptations have been made from the people living in the environments previously stated and they will be discussed further in the essay. The Sahara being the world's biggest desert, the Sahel slowly succumbing to desertification and deforestation, these are all challenges that people have overcome and adapted to. One of the environments this essay will be consulting is the Desert environment. The Sahara stated before, is the largest in the world, this means that life here will be very difficult due to the lack of water, shade, and grazing land. The Sahara is quickly getting larger and larger and people like the Tuareg nomads have adapted to this environment in many ways. They have adapted to the raging sandstorms by wearing masks or hooded clothing to protect their faces. They move from one place to another and do not remain still for a extended amount of time. Another way they have adapted to the Sahara is by trading goods....

...the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes. Hawking: How Humankind Will Survive the Future Listen, people of Earth: Everything's going to be fine. All we have to do is survive another century or two without self-destructing as a species. Then we'll get off this rock, spread throughout space, and everything will be all right. If this is not your idea of "optimism," then you are not Stephen Hawking. The esteemed physicist garnered headlines, and some eye-rolls, after telling Big Think last week that humanity needs to leave the Earth in the future or face extinction. As The Atlantic noted: He's not knocking climate scientists' attempts to figure things out on Earth-he's just thinking long term. "There have been a number of times in the past when our survival has been touch-and-go," explains Hawking at Big Think, mentioning the Cuban Missile Crisis, and "the frequency of such occasions is likely to increase in the future…. Our population and our use of the finite resources of the planet earth are growing exponentially along with our technical ability to change the environment...

...environmental effects of the disposable water bottle life cycle. In order to understand the water bottle life cycle, it would benefit you if you knew a little about the environment. So I will explain the normal functioning of water, carbon, nitrogen, and phosphorus cycle to start things off. Water plays many different roles on the Earth. Some is at the poles in ice caps, and some is in the snow and glaciers at the tops of high mountains. Some is in lakes and streams, and some is underground. Some is vapor in the atmosphere. But most of the water on Earth is in the oceans. Water is always on the move! The Sun’s energy causes water to evaporate from oceans and lakes into the atmosphere (Saundry). Plants and animals...

...microorganisms, investigated the living organism in a drop of water, their manifestation of the different attributes in life. During the run of the experiment, paramecium and specie 1 were observed and were tested to determine the impact of different stimulus to microorganisms in three setups. At the end of the experiment, the variety of setups has been shown to affect the number and kinds of species seen, such as placing hay infusion in dark and the other one, exposed to sunlight, adding brine and sugar solution on the setups. The third section of this paper will deal with relative number of species observed and seen. This paper tackles how microorganism thrive and exemplify mechanisms for survival in the different setups for comparison Moreover, this proves that even in a small drop of water, still, life can exist and microorganisms prosper. I. INTRODUCTION Life on Earth was said to have begun 3.5 billions of years ago. Until now it is still dominating, counting and adding years to life’s age. For an organism to be considered living or possesses life, they must portray different attributes of life. This include mainly by movement, irritability, contractility, perpetuation of life, adaptation, nutrition and growth and development. Living organisms come across our vision because of their relative size. We easily see living organisms that are huge in size like gorillas and for some cases, even small organisms like ants. However, not all living organisms are of size that...

...Everlasting, by Natalie Babbitt, Winnie Realized that life was not a life without and ending, every day should be lived like it is your last. The Tucks, who cannot die, all know that living forever is a bad thing because you have to live in the shadows and never meet any “lifelong friends.” The Tucks all were very thirsty and found a spring beside a big tree, so they all took a sip, later they realized that they weren't aging and knew that the water was special. It was eternal water. Death made Winnie live life like everyday is your last because it might be. Angus loathes living forever and wants a normal life. As well as Angus, Mae Tuck also dislikes living forever and really wants Winnie to do what her heart tells her...

...gasses and probably had a sky the color of a pinkish-orange. Its oceans containing large quantities of dissolved iron were most likely a kind of brown color. Life on early Earth began with very little amounts of oxygen compared to the quantities we have today, it was comprised of primitive elements and very slowly evolved into the Earth we know today. Had you been on Earth all that time ago, when it was just beginning to evolve, you would have died with just a few deep breaths! Earth’s early atmosphere contained little or no oxygen. It was primarily comprised of carbon dioxide, water vapor, and nitrogen, with smaller amounts of carbon monoxide, hydrogen sulfide, and hydrogen cyanide. Over time a controversial question emerged, could organic molecules assemble under the conditions on early Earth? In 1953, biochemists Stanley L. Miller and Harold C. Urey conducted an experiment to find these answers; they tested for what kind of environment would be needed to allow life to begin. To start they used water, methane, ammonia and hydrogen, component believed to represent major elements in early Earth’s atmosphere. These chemicals were all sealed and circulated inside a sterile array of glass tubes connected together in a loop, with one sterile flask with, and another flask containing electrodes. The liquid water was heated to add water vapor to the chemical mixture...

...because it’s a loyal action, and that action can change people’s point of view on you. The novel, A Long Walk To Water tells the story of Salva and Nya, teenagers living in South Sudan that have to struggle each day with their own issues. Nya has to walk 12 hours a day just to get water from a local source, and when Salva got more mature he helped out those people living there. He and his coworkers went down to Nya’s area of the country and they built a well. Another example, is the article, “In South Africa, volunteers deliver water to ease drought emergency.” There was a drought two years ago in South Africa, and government officials sent down trucks of water...

...Many people throughout the world never take the time to consider the living conditions of others. They fail to realize that not everyone has the same advantages as they do. Not everyone can afford the things they can afford. Not everyone has the resources they have, and not everyone will live as long as they will live. As Richard Skolnik, the author of Global Health 101, puts it, “Life expectancy has improved in all regions of the world since 1990, but at a slower pace in Sub-Saharan Africa than elsewhere (44).” If this does not touch your heart then I do not know what will. Just knowing that any region of the world’s life expectancy has declined over time is enough to make me wonder what can be done to turn it around. But in order to propose...

...how the conditions an individual has to endure can affect the outcome of that individual’s life. In Jesse Walters book, "We Live in Water" he gives readers examples of how an individual’s opportunity to progress or develop in life can be hindered by the surroundings they have to endure. The Title "We Live in Water" relates to a fish living in a fish tank, because no matter how many times that fish may swim to the glass of the tank it cannot change the outcome it has to suffer. In the collection, “We Live in Water”, two specific short stories, "Thief" and "We live in Water" shows readers how the environment and circumstances people...

...Ecosystem of the Rainforest An ecosystem is a relationship among the living and non-living organisms in a designated area and the environment in which they interact with. It includes plants, trees, animals, water, and soil. The rainforest ecosystem includes a variety of species, plants, and animals. All living organisms in this ecosystem physically adapt to the rain. The climate in the rainforest is very humid due the amount of rainfall. A tropical rainforest is very hot and wet; this type of climate is hit directly by the sun because of its location near the equator. The closer you are to the equator the solar radiation there is. The average temperature reaches about 77 degrees Fahrenheit. This climates temperature remains about the same all year never dropping below 64 degrees Rain falls at about 250 cm each year. Because the sun is directly hitting the rainforest, when the sun warms the ground and sea the water evaporates into the air. Warm air vapor and cold ail vapor form eventually causing clouds to form resulting to rain. This water cycle constantly repeats itself. Rain occurs more than 90 days a year in a rainforest. The rainforest consist of mainly trees and animals, trees can reach up to 164 feet in height. Because of the climate plants such as ferns and mosses or epiphytes, receive lots of water and direct sunlight so they grow very tall. Along with the many species of plants living in the rainforest, tropical animals such as Toucans, anacondas, and...

...October 2013 Topic of lecture: “A Drop of Life: Inside the Mounting Water Crisis.” The lecture by Shalini Kantayya (“SH”) highlighted the concerns over the water crisis as it is today, mainly water as a scarce/limited supply resource not being consumed efficiently, the hazards to health with the presence of dangerous chemicals in water, the difficulty faced by under-developed/ developing nations in obtaining drinking water and discussed the ethics of privatizing the supply of water - the ‘life-giving’ resource. One of the key messages of SH was that Water is Life and being such a precious resource it cannot be commodified. This was effectively conveyed through her film “A Drop of Life”, shown during the lecture. The film depicts the everyday ordeal faced by people in remote under-developed villages to obtain drinking water and how the privatization of the water supply through a prepaid system can lead to sanitation and health problems and even result to death. I also felt that it was no coincidence that the Supplier of prepaid water featured in the film is an American corporation, which to me deplore the fact that Americans seek to control the world and through water life on earth! SH also touched on many important facets of water utilization and management. I’m sure the lecture did stir the conscience of and prompt many of us to question whether we are consuming water efficiently. I certainly agree with SH that the water problem is not only restricted to the ‘others’...

...when discussing about living and non-living things. They are mostly specific on living things such as cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development and adaption through evolution. Things which have these characteristics are called as living things and things which haven’t are called as non-living things. On certain occasions we can identify living things that miss one or several characteristics from the list. For an example trees don’t show direct movements, just only the growth movements, neurons don’t reproduce, the animals that have non sexual reproductive system and the trees which are reproduced by propagation don’t show adaptations or evolutions. Importantly, some non-living things too show one or several characteristics that defines life. For an example if we think about computer it’s a logical machine, it consumes electricity. So it shows metabolism, it control its’ temperature. That’s homeostasis. It responses to stimuli. Every day its’ storage memory grows bigger. So it shows the growth. If we think about a vehicle it shows clear movements, it needs fuel to run. So that’s metabolism. While driving wheels turn where ever we turn the steering wheel. So that’s a response to stimuli. When we think about sun via nuclear reactions it gains energy. That’s metabolism. Consider about water, it floats; actually a movement. So it’s a living characteristic. 2. Snail is a living organism while a rock...

...as plants, water, food, etc. The health and sustainability of our ecosystem have been negatively impacted due to everyday poor decision making. Therefore, groups, such as Virginia Conservation Network, represents more than 100 non-profits and community organizations working together to preserve the ecosystem to prolong a quality life. Every living and non-living things are connected in some way. An ecosystem is a community of living and non-living things working together. The functioning of an ecosystem is often described by the flow of energy, via food chains and the cycling of elements biogeochemical (Chambers, 2000). The major component of an ecosystem includes soil, atmosphere, heat, and light from the sun, water and living organisms. Soil provides nutrients for plants, which provide oxygen. The atmosphere consists of oxygen and carbon dioxide for plants and living organism to survive. The sun’s heat helps water evaporate and return to the atmosphere where it turns into water. Light from the sun provides photosynthesis for plants to make food. Water is a large percentage of the cells that make up all living organisms. Without the existence of water, all and any form of life would be non-existent. Furthermore, without water, there would not be sufficient nutrients for any living organism, and for plants, that means they would die and would not be able to photosynthesize. If plants become extinct, all animals will extinct as well. The process of living organisms...

...Imagine, people living for 100 peso a day. So what do you think? “The world is very different now. For man holds in his mortal hands the power to abolish all forms of human poverty…” – John F. Kennedy Half the world is undergo financial difficulties in their daily lives. Worldwide, close to 1 billion people live in poverty on less than 100 peso per day and more than 800 million are undernourished. Their food and water supplies is at risk, and they’re houses and businesses destroyed once an extreme weather passed. The majority spent on basic necessities---food, clothing, shelter, and water. One must budget money for their everyday needs specifically food, to eat thrice in 24 hours but not all of them eat thrice in a day. Others buy clothes for they have enough money, but others just sewing their clothes to use it once more. Some of them living in dilapidated shanty by a railroad and others dying of hunger and agony. So how does one manage their daily spending with such a low income? What life is like on 100 peso a day? Shanty town life Poverty and hunger had always been the real enemy of human life and as we see our society developing, there are a few countries that are suffering even the worse. Philippines, top fourteenth poorest country in Asia which is more than 25 percent of the population falls below the poverty line. Unmanaged population growth is one of the main reasons for poverty in Philippines. Philippines, the Asia's fastest-growing economy, but tragically many...

...George Research Paper Water Water is a very important source that is well needed throughout the world. There is water damage and real problems in water extremely all around the entire world. Water has been more of an indirect source of conflict, rather than a direct source or cause for war. Are these problems that we really need to be having? No I wouldn’t say or think so and it should be better to try and solve these problems. Sometimes wars are fought on waterways. Water is the life’s growth for many things. Water is a very reliable source but it can have its scary downfalls, which can led to diseases, death, and no more water at all which would be terribly worst for the world, Earth, and humans. Everything needs water, without water mostly everything will die. Without water is like living breathing air without a heart or lungs. Water is very essential, pure fresh and it can also save a life. You have a great chance of surviving if you have pure fresh water throughout life. On the other hand unsanitary water is very harmful and is a natural killer alone, which can come from a disease-related issue. Water is a very well-being and important to many sectors of the economy. Water dissolves more substances than any other liquid. Do you think so? I can compare the cause of this with some additional information. Wherever water travels, water carries chemicals, minerals, and nutrients with it. Thus, there are a lot of people that lack access to safe water supplies approximately...
