According to Michael Pollan in his article “Why Bother?,” (2008), he declares that we as human beings needs action in order to alleviate climate change crisis we are facing today. Pollan says that no one is concerned about the simple ways to reduce carbon footprints on earth, for instance, planting a garden, biking to work and using a hybrid vehicles which will inevitably help to lessen the climate change. Scientists’ prediction about severe climate change has been rising rapidly in the Artic by changing white ice to blue water, giving off more carbon into the air. Everyone is responsible for maintaining the level of carbon footprints on this planet; however, environmental crisis seems to be the less significant subject to numerous individuals.…
Many aspects of the Earth have changed over the years since the start of the industrial revolution and the use of fossil fuels as the major source of energy in the developed nations of the world. Bill McKibben’s book Eaarth: Making a Life on a Tough New Planet focuses on these changes to the Earth that have been made, how the human population is going to be affected by these changes, and the new paths we have to take with agriculture and technology to survive on the new planet we created that McKibben dubbed Eaarth. The main idea of this book is to persuade the audience and help them understand that “by some measures we started too late, that the planet has changed and it will change more” (page 181) even if we immediately changed our ways…
A perfect example of a major event currently happening that will most definitely change the future of mankind, is the increase in human movement to different lands. In recent times the vast majority of these peoples are moving north, into Europe from various Middle Eastern nations, with their claim being they are escaping terror and ruin in the nations they once called their home. Although, this should be concerning to the vast majority of the people in the world today considering the times in the past that mass human migrations have happened. Initially, these…
Pluto was discovered in 1930, becoming the 9th planet in the solar system. As telescopes improved, other Sun-orbiting objects were discovered. Some of those were even larger than Pluto. By 2005, it was becoming apparent that many more…
Obviously, global change is definitely a massive issue that we as humans should handle in the near future. To start off with, global climate change is a severe change in weather patterns around the globe that affect thickness in the atmosphere, temperatures, precipitations, water levels, and food growth. In addition, this change greatly contributed to the increases levels of carbon dioxide concentrate produced by the use of fossil fuels. To support this claim, one way the global climate has been changing is shown on a graph measuring the amount of atmospheric carbon dioxide concentration existing which states that, “carbon dioxide concentration changed in the 20th century compared to Earth in the past based on the chart because the line…
Climate change; the gradual shift in weather patterns throughout the planet attributed to the use of fossil fuels used by humanity to make life more convenient and comfortable. People have been the stewards of the planet for roughly 200,000 years of which, the past 150 years would be classified as America’s peak industrialization, but this is a global issue and many nations have only recently begun their foray into industrialization, like China, India, Dubai, Saudi Arabia, Iran, etc.…
The term ‘Anthropocene’ is used to define the time period in which humans were affecting the earth’s atmosphere. Crutzen and Stoermer (2000) used this term to define the industrial era in which humans were affecting the greenhouse gas concentrations, however Ruddiman (2003) argues that the Anthropocene started thousands of years ago with early agricultural processes and plagues (Ruddiman 2003). Before industrialization there has been evidence to prove that humans had some impact on the atmospheric concentration of greenhouse gases as there were anomalous values in the concentration levels that didn’t follow the pattern of expected by ‘natural‘ behaviour suggesting that early human activities may have been responsible (Ruddiman 2003). This is as a result of anthropogenic agricultural practices as they involve deforestation and trees and much of the biomass cleared for farming were carbon stores and made up 25% of the world’s carbon stores (Ruddiman 2003) and many of these trees were burnt causing the release of CO2. The draining of wetlands and ploughing of rangelands have also contributed to the increased CO2 in the atmosphere dueto the decomposing of organic carbon(Salinger 2005) The growing of rice and farming of cows also contributes as it releases methane, and as humans…

For the last 2.5 million years, global temperature has shifted between cold glacial periods that last for around 100 000 years, and warmer interglacial periods that last for around 10 000 years. Right now we are in an interglacial period. 20 000 years ago the Earth was cold. Around 15000 years ago it started to warm up, this was the end of the last glacial period. Over the last 10 000 years the climate has been warm with minor fluctuations, however over the last 1000 years the climate has been fairly constant with small fluctuations in annual temperature. Over the last century global temperature has increased rapidly. This is called global warming; there has been a sharp rise in average temperature, 0.7oc between 1900 and 2000. The temperature increase over the last century has been very fast. There is a consensus among scientists that the changes in climate over the last century are a result in human activities (anthropogenic causes), including Al Gore, as shown in the statement which I agree with. I think the majority of global warming is due to humans therefore it is our right to try and find solutions to diminish global warming as much as we can.…
Earlier in the beginnings of Earth 's history climate changes were normally induced by different vibrant processes on Earth but recently it is caused by human activities. This is the reason that in our everyday talks the term climate change refers to climate change caused by global warming. The most disposed signs of climate change are glaciers that are presently melting at rapid level which entails climate change has already began. This time, climate change is only due to the recent human activities and had resulted in global warming process.…
Planetology is the branch of astronomy that deals with the physical features of the planets. Planetology studies include the origin and composition of the planets, and the solid bodies of comets and meteors found in the solar system.…
At first, I wish a very warm good morning to all of you present in this meeting. I welcome everybody with much pleasure to participate here. Today we are gathering here to celebrate the World environment day. At first, I am going to say something about the World environment day.…
Humans are responsible for global warming for many reasons and if it is not controlled properly it can affect the future of this planet. The burning of fossil fuels, mass deforestation, and increased population are all causes of global warming. "Global warming is believed to be caused by changes in the earth 's atmosphere as a result of industrial process."(Leggett 124) Global warming is the rise of Earth’s temperature causing a vast amount of issues. The sign that supports the human cause is abundant and powerful, some say it is normal for the planet to undergo such changes in atmospheric temperature. If we, as humans, do not change the way we use resources, our planet will be doomed for the future.…
