Recommended: How does the environment influence health
Over the last two centuries, humanity has become increasingly reliant on fossil fuels. Over that time, the consequences of constantly burning fossil fuels have accumulated into a threat to industrialized cities. The burning of fossil fuels causes acid rain to shower on cities and ecosystems around the world, tormenting their inhabitants. The increasingly deadly pollution caused by the burning of fossil fuels has caused the deaths of many people around the world by causing respiratory problems. Not only has the pollution worsened, but the supply of fossil fuels is not limitless – as humanity’s reliance increases the supply decreases, and that is all the more reason to break humanity’s reliance on fossil fuels. Fossil fuels should be replaced with cleaner alternatives because fossil fuels cause environmental hazards, are non-renewable, and are detrimental to human health. Ever since the dawn of the Industrial Revolution at the end of the 18th century, fossil fuels have been used constantly, slowly changing the planet’s atmosphere. According to Mann, “the preindustrial level of CO2 was 280 parts per million (ppm)” (N. pag). He predicts that at current rates, we will reach 560 ppm by the end of the 21st century. To make matters worse, Mann states that 450 ppm is dangerous as it will cause an increase in Earth’s average temperature by 2 Celsius. He recommends taking measures to keep CO2 at less than 405 ppm (N. pag). Mann takes note that in 2013, the value managed to reach 400 ppm (N. pag). It is needless to say that the point of no return is right around the corner. Unfortunately, the affects of pollution are already felt around the world. Pollution can cause many health issues and damage several organs in the body. When people think ... ... middle of paper ... ...i.

Since measurements began in 1958 -- and it can be assumed to have been the case since the industrial revolution -- emission of carbon dioxide into the atmosphere has risen steadily as a result of the burning of fossil fuels (Quay, pp 2344). Although there is much argument over the implications of increasing carbon dioxide levels in the atmosphere, there are several points that almost all scientists would agree on: firstly, carbon dioxide acts to absorb radiated heat; if present in our atmosphere will do just that to some extent. Second, the concentration of carbon dioxide in our atmosphere is rising. Third, the temperature of the planet is rising - although the amount of this increase and the causes of this rise are subject to disagreement (Philander, pp 193).
The Industrial Revolution was not only a turning point in the progress of human history, but the start of a great change in the Earth’s environment. Technological advances in industry and mass migration into urban areas led to a rising demand for energy sources, a demand met by fossil fuels. Casper, J. (2010) describes coal as ‘symbolic of the beginning of the Industrial Revolution’, the increased combustion of these ‘dirty’ fossil fuels further polluted the air and enhanced the volume of Carbon Dioxide (CO2) in the atmosphere. Changes in land use attributed to population rise, reduced the amount of photosynthesising biomass on Earth, diminished an important ‘carbon sink’ and concluded to enhance the Greenhouse Effect.

We cannot dispute that automobiles, factories, and power plants, displace an unprecedented twenty tons of carbon monoxide - per person - per year. There needs to be a reduction in emissions, yet we cannot focus on this aspect of global warming alone. There are many indicators that climatic change is influencing the frequency and intensity of natural catastrophes. If scientific global climate models are accurate, the present problems will be magnified in the near future.
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).
Hydraulic Fracking is a process to extract fluids that are trapped beneath the Earth’s surface. While this technique has allowed for an efficient and cost-effective way to tap into natural gas reserves, there are considerable environmental and health risks that have arisen. Over 596 chemicals are involved in the fracking process itself and many of these have been suspected of posing a significant risk to human physiology. There have also been several reports of physical disorders occurring in animals and people living around fracking well sites. Water from nearby areas has shown to display anti-estrogenic and androgenic properties that can impact endocrine function. Direct exposure of some of these fracking liquids to workers caused gastrointestinal, dermatological and neurological problems. Moreover, there are a host of environmental issues such as noise and air pollution and an increase in seismic activities. Certain countries have gone as far as to temporarily ban or suspend the use of this method. In my investigation, I will attempt to analyse the exact risks that are posed by fracking and what aspect of the technique contributes most to these problems. One of the goals of my research is to expand on the current knowledge on the toxicity of the chemicals and provide suggestions to the regulatory practices governing the operation. Through enhanced monitoring practices and proper disclosure of all the chemicals involved in fracking, there is potential for improving the safety of the process.

The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
The effects of using fossil fuels are starker than their timelines. Humans release approximately two billion metric tons of pollution annually, mostly from the burning of coal, oil, and natural gas; this pollution is destroying our environment and the ozone layer. Ozone and smog damage forests, crops, and other plant life, and reduces visibility. Other pollutants have the same
The burning of fossil fuels has greatly harmed our environment and is a leading cause as to why climate change has become such a threat to our way of living. In May of 2013, the carbon dioxide levels in the atmosphere reached 400 parts per million, an increase of more than 40 percent since the beginning of the Industrial Revolution. This could cause the Arctic Ocean to be nearly ice-free during the summer by 2020(Overland and Wang, 2013).
There needs to be a reduction if not extinction with the increasing amounts of carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), per-fluorocarbons (PFCs) and nitrous oxide into the atmosphere because it is directly affecting global warming. The combustion of fossil fuels and greenhouse emissions mainly contribute to the increase of these gases. The longer we go without solving this global problem the more conflicts we will have in the future. Although global warming does make the earth warmer there is more to worry about than heating to death. Major concerns revolve around effects on agriculture, water resources, ocean level and coastal regions, and disease. Many scientists and experimenters still disagree with global warming using excuses such as ‘primitive’ climate models, which predict global warming trends, can not accurately simulate the Earth; it is too difficult because there are thousands of variables to consider. With the issue of global warming alternative sources of energy are looked for. “Data indicates that hydrogen is [the] only suitable future fuel.” (Williams, 102). Many scientists agree, but how long will it take for us to get there?
Fuels like coal, and oil that once were a fine innovation in creating energy are now rapidly deleting and one day will be gone forever; energy that won’t last is often referred to as non-renewable energy. Besides being set up to fail and become inefficient in the future, fossil fuel energy is not clean to use and poses several environmental complications. Coal, for instance is “the dirtiest of all fossil fuels. Coal combustion not only produces sulfur oxides and nitrogen oxides that contribute to acid rain and snow, it generates millions of tons of particulates that cause asthma and other respiratory diseases.” As with all usage of fossil fuels, it creates enormous amounts of carbon dioxide, which contributes to greenhouse gas. Not only are fossil fuels dirty, they also pose as a security risk and unforgiving on the American wallet. (Saini)
