Today, the influence of the People’s Republic of China is felt around the world. Its global economic and diplomatic presence has led to speculation that China will be or already is the next superpower. However, China was not always so involved in the world and the motivations that drove China to extend its influence and ability to project power remain a subject of debate. There are two major schools of thought on what motivated China to become a global actor. Certain scholars such as David Shambaugh

The world’s largest source of emission-free energy is nuclear energy. Energy sources like solar power, wind power, and hydro electric power are also good ways to produce clean energy; however, when it comes down to it they can’t produce the capacity of energy the world needs. The two largest problems with fossil fuels are that they are running out and produce greenhouse gases when burned. Greenhouse gases are gases that absorb and emit radiation inside the atmosphere. The main greenhouse gases in

Global warming was first mentioned by ‘Svante August Arrhenius in 1896’, but in ‘1753, Joseph Black discovered carbon dioxide’ and in ‘1827, Jean-Batiste Fourier suggested that atmospheric effect kept the earth warmer than it would otherwise be’, (Direct.gov. n.d. A history of climate change). Since this time, reports, and study have be done with graphs to show the impact of global warming and what could happen to our planet. In 1979, the first conference was held this was called ‘International climate

Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot

Erin Williams April 30, 2015 Anthropology Edwin Accomando Paging Captain Planet We need a major reduction in human population, stat! Ok, maybe that’s not a viable solution, but it does beg the question; “How many people does it take to break the world?” Currently, there are a little over 7 billion people on the planet and there is already some cause for concern. Overpopulation, extreme weather, and a drought that’s causing a water shortage. Is the abundance of humans the cause or is it simply

process of these greenhouse gases collecting in the atmosphere is causing the temperature on Earth to increase. The two main causes of anthropogenic climate change are the burning of fossil fuels and deforestation. Burning the fossil fuels coal, oil and gas releases carbon. Trees naturally absorb

Ice cores taken from the Arctic have shown that carbon dioxide levels are much higher now than the last thousands of years. The higher amount of carbon dioxide in the atmosphere means warmer temperatures. There is now stronger evidence linking the warming of the ice to human activity. Global warming is caused by the green house gases, which leads to the melting of the ice, thereby affecting the ecosystem. Therefore, there is a need for everyone to reduce the amount of carbon emissions that causes

Ricardo Arias ENVS 300 Professor Fieldman May 13, 3015 Journal #3 For my second activity, I attended a meeting of Fossil Free SFSU. This organization is fighting to completely divest San Francisco State University from any connections with the fossil fuel industry. Meaning, this organization is campaigning for SFSU to eliminate all stocks, funds, bonds, etc.- anything associated to fossil fuels. I attended the meeting at a perfect time because it was sort of an introduction to what the

from pre-industrial to transitional to post-industrial phases, the amount of greenhouse gas emissions from the burning of fossil fuels increased by an unthinkable amount. Greenhouse gases negatively impact the world environment because it can cause smog pollution, acid deposition, water contamination, habitat destruction, and the loss of biodiversity. As of today, fossil fuels such as coal, oil, and natural gas continue to negatively impact the world environment and its ecosystems. However, world

Mallory Reynolds Megan Condie April 21, 2015 Essay #4 Meat In Diet & Livestock Production Every five years, the U.S. Department of Agriculture updates the American government’s dietary guidelines. These guidelines advise Americans about what is healthy for humans to eat, but in 2015, for the first time, these guidelines named “The Sustainable Power Plate” also reflect what is healthy for the global environment as well by suggesting eating meat in moderation, if at all. The evidence of rapid climate
