Earth has gone through tremendous changes in the past 4.6 billion years. From a united continent to seven continents spread all around Earth’s crust, species have evolved. Today, these changes are partly caused by human beings, rapidly causing a massive extinction—one that Elizabeth Kolbert calls the sixth extinction. Kolbert argues that due to humans getting involved in atmospheric and oceanic procedures, as well as affecting the principles of geographic distribution, we are either already in the process or at the very edge of this extinction. “We are running geological history backwards,” she stated during her lecture at Skidmore College.…
There has been an in-depth discussion about the state of the human population, mostly the effect of the Earth's carrying capacity has upon the global population. The carrying capacity of an environment is the maximum population size that can be supported by the resources available in the environment. Once an environment has reached this maximum capacity in regards to the resources, the population growth oscillates around the environment's carrying capacity. Density-dependent regulations mostly occur when there is a limited about of food or other resources available to the population. This creates an environment where the population is forced to compete for the resources, or the environment is so dense with the population that the population…
An essential key to life is reproduction. Though out the last couple of years, the world population has expanded in great amounts. There are many factors which are allowing approximately 7.3 billion people to survive on one earth. Some believe that in the upcoming years, we are inviting trouble for ourselves. Our world population is expanding every day and the earth is unable to keep up with all our every day activities.…
Throughout human civilization, Earth has to face dramatic changes on its surface after the growth of technology, population growth, and climate change. The increasing people and the growing business are affecting the earth's biosphere and threatening the people's health. If we didn't start protecting our planet's atmosphere, surface, and ecosystem, and then our future generation: children, grandchildren are in jeopardy. This book " Bussiness, Ethics, and the Environment' is written by Jospher R. Desjardins. From this book, I am picking chapter two "The Biosphere: facts and Values" and talk about how does change does change in the business affects the earth's biosphere and the people's health.…
Assessment one: A Global Issue Review Climate change The Earth's climate has been changed throughout history. Almost in the last 650,000 years there have been seven cycles of the glacial advance and retreat, also with the rapid end of the last ice age about 7,000 years ago marking the commencement of the modern climate era and of human development. Many of these climate changes are attributed to very slight difference in Earth’s circle that change the amount of solar energy our planet receives. Ever since the establishment of human development, the mankind has been living in a competitive relationship with nature. The relentless chase of progress, comfort and security has caused a massive increase of stress on environment, particularly from the industrial revolution.…
Humans risk upsetting the ecological balance of the Earth as well as the change of regional climate. The more people there are, the more air, water, more education, housing and employment opportunities are needed. According to United Nations, it is estimated that by 2020,…
Effects on our Environment Explanatory Synthesis In the articles “Overpopulation Is Not the Problem” by Erle C. Ellis, “Overpopulation Is Not the Problem? Really?” By Robert Walker, “Overpopulation Is Still the Problem” by Alon Tal and “The Overpopulation Myth” by Fred Pearce each author discusses the issue of overpopulation and how it has become a debate among many as to whether it really is as big of an issue as some may think. All four authors have strong opinions on whether or not they believe that the increase in overpopulation is a more substantial issue than consumption.…
Living things have been vanishing since the start of life on our planet. Truth be told, most species that have ever lived on Earth are presently wiped out or never again living. Right around 50 percent of plant species and 75 percent of creature species, including the dinosaurs, wound up terminated. Species are constantly vanishing. This is the aftereffect of infections, rivalry from different species or the regular change in their atmosphere.…
Population is the amount of people in a specific area, but what happens when one area becomes overpopulated? The population from that area has to move out into other areas causing a growth to other areas. This growth effects the environment in the newly populated areas tremedously, which in turn effects the citizens living there. A never ending cycle between homo sapiens and the Earth, who will win is the question no one really knows. Throughout antiquity…
The proliferation in population has caused environmental catastrophes, various environmental issues arising from overcrowded societies.…
Over the past century, the average temperature of Earth has increased roughly 1.53 degrees fahrenheit from 1880 to 2012 which is an alarming number. Global climate change is a serious matter at hand and it is not something that can be overlooked, the world needs to assess the situation and come up with a solution to resolve this growing problem before it is too late. There has been many questions that have developed over the years in regards to how climate change has impacted the Earth both positively and negatively. Over the years, there have been many widespread speculations that humans are one of the main contributing factors to the major physical changes that the world has endured over the years and based off various scientific studies…
Mass Extinction of the Human Species The future is not guaranteed for individuals, and the same is true for all of humanity. Of the millions of species that exist on this planet humans are known as the most intelligent, but maybe this is a misconception. While mankind carries on its activities, the chance of a mass extinction grows with every misuse of the earth. It is more likely that humans will cause their own extinction than it is that they would be wiped out by a natural catastrophe.…
Understanding the history of world population, the causes for world population growth, the factors that contribute to this problem and finally the effects of the world population, will aid in finding a solution. This history of world population reflects significant changes at the industrial…
While the increasing world population stimulates an increase in demand for resources, human activities have been changing the makeup of the atmosphere, damaging the environment which provides those resources. Common practices such as burning fossil fuels and removing forests have released unprecedented amounts of carbon dioxide in the atmosphere, resulting in a worldwide increase in temperatures referred to as climate change. This increase in heat alters water cycles, effecting significant changes in the availability of fresh water. In addition, abnormal temperatures can disrupt the variety of plants and animals in ecosystems as well as weaken agricultural productivity. As a catalyst for climate change, overpopulation contributes to this increase…
It has been proven that what caused climate change is not only due to human factors but natural factors as well. As in the article “causes of climate change”, it talked about how the natural and anthropogenic effects are causes of the changes in our climate. Some natural causes are the effects of plate tectonics, volcanoes, the earth’s tilt, and ocean currents. Plate tectonics, where countries and “continents were all part of one large landmass” (Causes of climate change. Retrieved November 23, 2015 ) in the past, at some point in time moved into different positions and drift apart, caused continents around the earth to experience different climate conditions than they used to experience before this shift in their positions.…
