Using Waste for Energy One of the most important environmental issues faced by our generation, as well as future generations, is without doubt energy. This is of major concern because we are using up our nonrenewable sources at a much faster rate than they are being replenished, but at the same time we have yet to perfect ways to completely replace nonrenewable energy with renewable energy. The article “Could Generating Energy from Waste be the Answer?” explains how researchers at Teesside University have discovered a way to produce biofuels using waste. I personally found this article interesting because it gave me new hope and insight into producing energy from sources I hadn’t previously given much thought to. Biofuels are a great source of renewable energy because they do not create harmful environmental by-products like other fuels. However, according to Dr. Komang Ralebitso-Senior, Senior Lecturer in Molecular Biology at Teesside University, they create what she calls a food-fuel conflict. As Ralebitso-Senior expresses, biofuels “can encourage farmers to grow energy crops at the expense of badly-needed food, particularly in poorer countries in the world” (par. 2). Farmers often make more money growing crops to use for biofuels rather than food. This can cause a problem because as crops grown for food decline the prices to purchase them increase. Before reading this article, I had never given much thought to how producing crops, such as corn, for fuel cuts back on what we as consumers are able to buy at the grocery store. However, this makes sense and although I think it’s great to use these crops for fuel, I can see how it creates a problem as far as food shortages are concerned, particularly in underdeveloped countries. Fortunately, Dr. Ralebitso-Senior and her researchers are discovering new ways to use waste, such as domestic refuse and sewer sludge, to produce energy through the process of anaerobic digestion, which “uses naturally-occurring micro-organisms to break down waste in closed vessels” (par. 5). Although anaerobic digestion is currently being used by some waste-to-energy companies, Ralebitso-Senior claims that there is still a lot to be learned about this process. According to her, anaerobic digestion is not being utilized to its full potential, something she hopes to change as her research continues. Although I am hopeful that she and other researchers will continue to develop better ways of using anaerobic digestion to transform waste into energy, I know it will most likely take years of investigation to fully understand and utilize this process. Another point the article made that I agreed with was that if we are using waste to produce energy, than there will be less waste in landfills. Ralebitso-Senior states that “the refuse from which the biogas is produced would have ended up in landfill, with possible damage to the environment…” (par. 10). I think this is great news because not only would this energy source be truly sustainable, but it also has the added benefit of reducing the amount of waste and damage to the environment. Overall, I believe that Ralebitso-Senior sums it up best when she says that "the value of biofuels is their potential to be sustainable, providing a good balance between the environment, the economy and society” (par. 11). I could not agree more with this statement as I believe it acknowledges what producing biofuels is really all about. Although I am certain she and her researchers have a long road ahead of themselves, after reading the article I am also very hopeful that someday they will fully understand the process of converting waste into energy.

...Article: Community Resilience and Oil Spills in Coastal Louisiana | BIOL_115 – Environmental Science | Professor Dr. Heather Smith | Written By: Davin Alex | 10/28/2012 | | Write A Paper That Identifies What Question Is Being Debated. After reading the article on, “Community Resilience and Oil Spills in Coastal Louisiana”, it is quite clear that the unnoted question is, “How have the oil spill affected the coastal Louisiana—the pros, the cons, the cause, and the effects. For several months, this particular oil spill in the Gulf of Mexico has dominated international headlines. Since offshore oil extraction began in the 1930s, these coastal residents have coped with spills and other forms of ecological damage caused by exploration and pipeline-related activities. The harms of oil drilling along offshore coasts have been manifested by the recent accident the Deepwater Horizon exploration-well located in the Gulf of Mexico. It's easy to see the damage done to oceans, marine inhabitants and coastal communities, but there are other harmful effects as well ( I live in Florida, and I have personally spoken to former residents of Louisiana, and they have stated that the discomfort of how their once clean and beautiful waters was appealing. Due to the spill, the waters are being scorned and to make matters worse it has affected most of the businesses on the coast, negatively. Identify...

...Environmental Fundamentals ENV/100 Environmental Fundamentals The fundamental principles of environmental science will be discussed in this paper and the definition of environmental science along with the elements and principles related to it will be addressed. The concept of environmental sustainability and the historic patterns surrounding will be describe, along with human values and how it affects the challenges in society. Examples of environmental hazards and how they affect the health of humans will also be provided. There are many environmental issues facing the world today. To try to understand how the natural world functions is not an easy concept to comprehend and definitely not an easy responsibility to put on society. This is why it is important to know and recognize the significance of environmental science. Environmental science is the interdisciplinary study of humanity’s relationship with other organisms and the nonliving physical environment. As human population continues to reproduce, as technology progresses and the wants and needs of humans multiply, society’s impacts on the world become harsher, despite the improvement in some areas.  Environmental impacts can affect the health of humans and a human’s wellbeing. After reviewing research on the environment, environmental hazards directly affect human health. One major environmental hazard to human health is pesticides. These......

My scout master was on the other side of the spectrum. He grew crops and believed Global Climate Change is a hoax. It was a world of difference when they talked about growing food. My AP Environmental Science teacher -- Ms. Houser, rambled on and on about how she planted this one tree next to these plants for reasons x, y, and z. My scout master blathered about the quality of soil, pesticide, and the cost of water. Ms. Houser wanted us to be interested in class and help make a rain garden outside. My scoutmaster wanted the price of beans to go up in the grocery store, so he could get more money. Ms. Houser was conscious of her impact on the environment. Whereas My scoutmaster didn’t feel connected to the environment; he saw it as a way of making a profit. The native plant...

Scientific Method and the Problem-Solving Approach

...Scientific Method and the Problem-Solving Approach The term "environment" refers to the sum total of our surroundings, including biotic and abiotic factors. Environmentalism is a social movement dedicated to protecting the natural world from undesirable changes brought about by human choices. In contrast, Environmental Science refers to the pursuit of knowledge about the workings of the environment and our interactions with it. It incorporates the study of both "hard" science subjects such as biology, chemistry, and ecology and social sciences, such as economics and policy. In this paper, I will review an environmental situation and attempt to apply methods of study from both the "hard" and social sciences. Consider this. A dairy farmer in Wisconsin loves to fish in a tiny lake adjacent to his property. In recent weeks, he has had terrible luck, catching few or no fish every time he goes out. He also notices that the lake has an unusually high amount of algae in it. Clearly, the reason for a short supply of fish and an increased amount of algae in the lake is contributed to algae blooms. These blooms are caused by “loads” of nitrogen flowing into the canal. Based on this information, I predict large amounts of chemical fertilizers are being applied on nearby farms and subsequent run-off enters the lake (Withgott & Laposata, p. 9). This occurrence then produces massive algae growth which not only obstructs sunlight, but also starves the water of oxygen, resulting......

However, the greatest causes of water contamination and quantity abuse in the United States come from agricultural production (United States Environmental Protection Agency [EPA], 2012a), which is defined as a nonpoint source that pollutes with nutrients. In 2011, nine of the top ten corn and soybean producing states were located in the 2 Midwest (United States Census Bureau, 2012), making this region the largest agricultural region by volume produced in the U.S., and thus prone to environmental problems with alarming consequences. In order to meet production demands while bound by constrained budgets, farmers often turn to unsustainable practices to ensure a yield. These include irrigating their fields with groundwater (the water from natural basins underneath the ground), applying excessive amounts of nitrogen and phosphorus as fertilizer, and plowing the land in a way that reduces quality of soil structure (United States EPA, 2012b). All of these factors directly result in the rapid depletion of......

Environmental Science Term Paper

...Environmental Science 5. Tropical forests represent a large reservoir of underutilized timber. Why is it ecologically unsound to harvest most tropical forests? What are the potential long-term effects of deforestation in the tropics? Harvesting our Earth’s tropical forests is very ecologically unsound in many ways. These forests are being harvested and clear-cut in staggering rates and even if we begin taking necessary actions as a whole, worldwide, immediately we still may never get these forests back to where they should be in order to become sustainable once again. The most commonly known effect that harvesting the rainforests has had is the extinction of the majority of the world’s species. The tropical forests contain about half to two-thirds of the world’s species. (Chiras, P. 230) An average of 137 species of life forms are driven into extinction every day in the world's tropical rainforests. Destruction such as harvesting in rainforests have contributed to the loss of millions of acres of tropical rainforest. Animals and people alike lose their homes when trees are cut down therefore, most animals and other species die when trees are cut down. Larger mammals need several acres to be able to roam free and are trapped into smaller living conditions and several other species are only known to be living in one region and will not survive once their habitat has been harvested. Other animals that may not be native to these tropical areas also suffer when......
