I have always been amazed by the ocean’s immensity. During my childhood’s summers, I used to go to the beach with my family and always asked me the same question: What was the purpose of the huge water mass in front of me? What were the wonders hidden in the ocean? As I grew, I decided I need to find the answer to those questions and studied Marine Sciences at college. While advancing in my degree, which I was projecting in physical oceanography, I realized that it was not only a matter of physics but ultimately, a series of feedbacks between other natural systems in the Earth and even out in space.
Thus, I felt the need to satisfy my curiosity and start a degree in Environmental Science while finishing Marine Science. Time was against me, I only had to take two more years in order to finish the degree, and I focused on what really interested me at that time, anthropogenic pollution and climate change, which it became very famous by that time. It was during the second year that I enrolled in a course named Environmental Change in the Quaternary. This course taught me that global change is not only the raise in temperature, that the humanity is facing a problem of immense dimension, and it addressed my interests into a new theme, the global change.
After finishing college, I was awarded with a PhD

Our group studied the potential bioindicators that can be used to detect CO2 leakages. Particularly, the research focused on: the autochthonous vegetation, the microbiological community, the microfauna and the soil-air fluxes of CO2. As a member of the team, I was in charge of the monthly CO2 flux measurements to study the factors controlling the type of leakage such as the soil compaction or humidity. During this time, I also had the opportunity to interact with other ecological research teams understanding the sampling and analytical methods for these

The environment has become a popular topic this year due to our on-going drought. It has always been a serious issue; something Saukko informs us in her sarcastic essay “How to Poison the Earth”. She uses sarcasm and irony in her essay hoping her readers will do the complete opposite of what she is saying because of the stress she puts on the harming chemicals we use every day. We do not appreciate our environment and take it for granted. This ideal is what Ehrlich's essay “Chronicles of Ice” focuses on by using analogies and scientific definitions to describe aspects of glaciers. The melting of the glaciers introduces us to the topic of global warming and how our society is doing nothing to stop it from getting worse. Gawande’s “The Cancer-Cluster
One of the remarkable Tim Flannery’s contributions to society is the fact that he raises an awareness of climate change so that people think climate change regards as clime catastrophe. In the book, The Weather Makers: The History and Future Impact of Climate Change, Tim Flannery warned carefully and rationally to skeptical people on climate change. These people believe that increase of temperature on the earth is simply natural phenomenon since temperature has not been constant in whole history of the earth. Tim describes that this belief has tended to put the earth severe stage. In accordance with Gaia theory, this planet is an organism to purify by itself, but human being is likely to force it to lead to disaster. Tim explains that humans have been living in glacial epoch that the average temperature is approximately 14 Celsius and even rise of 1 Celsius will bring us anomalous situation (Flannery 2006, p.11). He warns that the temperature change will make difficult environment to survive in the earth. As Tim Flannery has well-informed academic knowledge about zoology and sufficient field experience, especially in Papua New Guinea, he explains wide various
Climate change has become of the world’s major issue today. The earth’s climate is always changing in a very fast and also in different ways. Climate changes affect our lives psychologically, emotional and also physically. Climate change is defined as a long term change in the earth’s climate, especially a change due to the increase in the average atmospheric temperatures. Due to this change in temperature, a lot of changes has occurred in our environment, these changes include rising sea levels, flooding, melting of polar ice caps, hotter days, colder nights and heat waves. These climate changes plays an important role in shaping our natural ecosystem, our human economics and also the most important, it affects the human race. For
One of the most compelling and difficult environmental problems society faces today is climate change. People do not realize how much the environment has changed for the worse in the last ten years, until they are told that the last two decades of the 20th century have been the hottest in the last 400 years, according to climate studies (Conserve Energy Future). Today, the carbon dioxide levels have reached 396.81 parts per million (ppm). “Carbon dioxide (CO2) has also increased over the last 100 years-- from about 300 ppm to 370 ppm. Interestingly, the majority of these additions have occurred in the last 50 years, when temperature increases have been the slowest” (geocraft).
Climate change is the main topic of this Encyclical. Climate change is portrayed in a way that reflects the current scientific consensus today. Hans Joachim Schellenhuber, a leading climate scientist, was a scientific adviser to the Pope while writing Laudato Si’.

Earth has been called the blue planet and not without reason. The ocean covers about three quarters of the earth’s surface and plays a vital role in our survival. It bounty feeds millions of people daily. Its surface absorbs more than ninety five percent of the solar radiation that reaches our planet. It is integral to the water cycle and it regulates our planets climate. But none of these roles would be fulfilled without the movement of the ocean. The currents, ribbons of movement within the greater body of water, provide the means with which our ocean distributes the nutrients and energy necessary for continued life upon earth. What are these currents and why are they so essential to our survival?
Despite the evidence to the contrary, many interest groups with considerable political clout have successfully perpetuated the argument that documented changes in the environment are a product of natural cyclical changes in climate, and are not associated with human activities. However, even the acceptance of this particular brand of reality is no grounds for the disregard of environmental consciousness. Even if one accepts the premise that recent climate change is not a result of human activity, the rationale behind environmental conservation remains valid.... ... middle of paper ...
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.
Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now. If we continue to destroy the planet with no regard as to how serious this matter is there could be several negative effects to us as human being and other living thing on Earth. This is why global warming is truly a global issue and needs to be tackled collectively. We must to act now in order to reduce the dangerous levels of carbon dioxide emissions and we must to work together.
Restate Thesis: It is important to know our earth is at a high level of risk of pollution and growing changes through global warming.

The earth is a complex system, which continues to evolve and change. Climate change and global warming are currently popular in the political agenda. But what does “climate” really mean? The difference between weather and climate can be conveyed in a single sentence: “Climate is what you expect; weather is what you get.” Based on research of the geologic record, we know that climate change has happened throughout Earth's history and at present, ever-increasing evidence points to the roles that humans play in altering Earth systems. The Earth and its atmosphere receive heat energy from the sun; the atmospheric heat budget of the Earth depends on the balance between incoming solar radiation and outgoing radiation from the planet; which has been constant over the last few thousand years. However present evidence seems to suggest that the recent increase in temperature has been brought about by pollution of the atmosphere, in particular the release of huge amounts of carbon dioxide, mostly through Anthropogenic Forcing (human activity) and other various internal and external factors. I...
Environmental studies is a paramount field to focus on for both the present day and the future. This field of studies pertains to all people, animals, plants, and biomes around the world. Environmental Studying is important because it is only by understands the environmental processes that we can begin to take the steps necessary to correct the on-going damage that is occurring, and ultimately protect and sustain life on the planet. Unless steps are taken to try and abate and control environmental problems, which are often human-generated or exacerbated, then the environmental that we live in will continue to deteriorate. There is no life without protecting the source that sustains us. Even though I have only been alive for seventeen years, it has been long enough to see many negative environmental changes. Since I was born that population has grown by over one billion people causing deforestation, loss of wildlife, increased pollution to both air and water, and even superbugs. However, I have also been able to see extremely positive results such as an increase in the research and implementation of renewable resources. The reason I am so motivated to study environmental science is because I know that change is possible. Those who study environmental science and study have the ability to help reduce, and possible reserve, some of the damage that has been done to the environment while at the same time, helping to advance the well-being of our fellow humans.
