Geothermal Energy: An Innovative Solution
The earth is slowly being destroyed because its people hunger for energy. Currently, energy is mostly produced from fossil fuels, which cause great damage to the environment. The use of geothermal energy helps to alleviate some of the pressure on oil and coal, and is much gentler to the environment. People in areas surrounding geothermal plants, and those who work on or in the plant are affected for the better. Geothermal energy is a clean and renewable resource, and a great boon to life on earth.
With minimal pollution, the resource of geothermal energy is kinder to the environment than its energy-producing counterparts in coal and oil. There are essentially zero emissions due to the nature of the geothermal plants. They do not use many toxic materials in energy production. Though chemicals have the potential to damage the water supply, they are properly contained (National Geographic Society, “Geothermal Energy Information”). Because geothermal plants are usually located in remote areas, it is hard for the water to get to a place where it could affect people. The resource of geothermal energy causes minimal damage to the environment, but it is also a positive influence on many people.
Both the common good and individual rights are valued in this power source. It provides power constantly and creates jobs for locals (Union of Concerned Scientists, “How Geothermal Energy Works”). Pessimists may point out that it is expensive to build geothermal plants, but the operating costs are very low, allowing it to be competitive with other energy sources (Center for Climate and Energy Solutions, “Geothermal Electricity”). Constant power running at a fixed rate benefits the common good, specifical...

For example, substrate concentration, enzyme concentration, and temperature could all be factors that affected the chemical reactions in our experiment. The concentration of substrate, in this case, would not have an affect on how the bovine liver catalase and the yeast would react. The reason why is because in both instances, the substrate (hydrogen peroxide) concentration was 1.5%. Therefore, the hydrogen peroxide would saturate the enzyme and produce the maximum rate of the chemical reaction. The other factor that could affect the rate of reaction is enzyme concentration. Evidently, higher concentrations of catalase in the bovine liver produced faster reactions, and the opposite occurs for lower concentrations of catalase. More enzymes in the catalase solution would collide with the hydrogen peroxide substrate. However, the yeast would react slower than the 400 U/mL solution, but faster than the 40 U/mL. Based on this evidence, I would conclude that the yeast has a higher enzyme concentration than 40 U/mL, but lower than 400
The Alberta Oil Sands are large deposits of bitumen in north-eastern Alberta. Discovered in 1848, the first commercial operation was in 1967 with the Great Canadian Oil Sands plant opening, and today many companies have developments there. The Alberta Oil Sand development is very controversial, as there are severe environmental impacts and effects on the local Aboriginal peoples. This essay will discuss the need for changes that can be made for the maximum economic benefit for Canada, while reducing the impact on the environment and limiting expansion, as well as securing Alberta’s future. Changes need to be made to retain the maximum economic benefits of the Alberta Oil Sands while mitigating the environmental and geopolitical impact. This will be achieved by building pipelines that will increase the economic benefits, having stricter environmental regulation and expansion limitations, and improving the Alberta Heritage Fund or starting a new fund throu...
The reason for this report is to increase the reader’s knowledge on the Alberta Tar Sands, which will allow them to create their own opinions on the situation. It is a very pertinent issue in politics and will have a very large effect on the carbon emissions of Canada. Also, I wanted to further my understanding of the Alberta tar sands and learn the side effects of the tar sands. How the tar sands are different from other oil and energy procurement methods and which method is more energy efficient? Would the construction of the Keystone XL pipeline in the United States be an intelligent way for the US to involve itself in the tar sands? I wanted to answer these questions by knowing the real facts about the tar sands versus what the oil companies are telling the consumers. The ability to assess the entire situation will allow both the reader and I to formulate our own opinions about the tar sands and whether the extraction of oil at the tar sands should continue.
...sumption, creates emission of greenhouse gases and other harmful chemical materials. Once released into the air, it can cause environmental problems, which in turn threatens not only the environment, but also the health of the people who live in it. In order to reduce the use of energy to help protect our planet and our health, the diamond mining industry has implemented renewable energy programs to monitor energy and carbon emission. Since its beginning, mining company PHP Billiton program has saved an equivalent of one million liters of diesel fuel per year at their Ekati Diamond Mine in Canada’s Northwest Territories. The health of the environment and the health of humanity are as one. Whatever we do to our planet, we do to ourselves. Reducing energy consumption of diamond mining not only helps protect our planet, but also helps protect the health of our people.
The author discusses the enticement to political groups because of geoengineering’s alleged potential to reverse global warming rapidly and cheaply, as he presents concern regarding the significant risks and the threat of technology gone wrong. The author looks at the basic authority issues raised by geoengineering, its possible functions, governance, and specifically addresses inadequate research funding, rejection, and unilateral vs individual action. Bodansky is a professor at Arizona State University Sandra Day O 'Connor College of Law and has written three books and dozens of articles and book chapters on international law, international environmental law and climate change policy.

Canada is great economic superpower that has yet to reach its potential. As the second largest nation by area, we possess vast natural resources. We are a massive importer and exporter on the world stage, who a play a vital role in the stability of the northern hemisphere. Through Canada’s international trade, we export vast quantities of many different foods stuffs, minerals and manufactured goods like cars, while we tend to import lots of Iron, Aluminum and Steel. Our relations with neighbouring nations have been integral in the success of our trade. In 1994 Canada became a member of the North American Free Trade Agreement or NAFTA with the US and Mexico. NAFTA reorganized Canada’s and America’s trading systems to work as one. The trade issue of recent months is about the rising costs of energy in Canada and in the United States. Newly elected President George W. Bush now is proposing a North American energy initiative for a continental power grid. This proposal puts Canada in a very uncomfortable situation. On the one hand we would love to share our resources and appease our super-power to the south. But on the other we prefer to leave our pristine land alone. The growing trend nowadays is that politicians are the ones wanting to please the Americans by giving away our resources, while it is the activist who is concerned about the vast environmental damage this energy legislation could entail.
In this lab, it was determined how the rate of an enzyme-catalyzed reaction is affected by physical factors such as enzyme concentration, temperature, and substrate concentration affect. The question of what factors influence enzyme activity can be answered by the results of peroxidase activity and its relation to temperature and whether or not hydroxylamine causes a reaction change with enzyme activity. An enzyme is a protein produced by a living organism that serves as a biological catalyst. A catalyst is a substance that speeds up the rate of a chemical reaction and does so by lowering the activation energy of a reaction. With that energy reactants are brought together so that products can be formed.
Enzymes are types of proteins that work as a substance to help speed up a chemical reaction (Madar & Windelspecht, 104). There are three factors that help enzyme activity increase in speed. The three factors that speed up the activity of enzymes are concentration, an increase in temperature, and a preferred pH environment. Whether or not the reaction continues to move forward is not up to the enzyme, instead the reaction is dependent on a reaction’s free energy. These enzymatic reactions have reactants referred to as substrates. Enzymes do much more than create substrates; enzymes actually work with the substrate in a reaction (Madar &Windelspecht, 106). For reactions in a cell it is important that a specific enzyme is present during the process. For example, lactase must be able to collaborate with lactose in order to break it down (Madar & Windelspecht, 105).

Geothermal energy is one of the oldest sources of energy. It is simply using and reusing (reusable energy) heat from the inside of the earth. Most of the geothermal energy comes from magma, molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs, geysers, pools of boiling mud, and fumaroles are the most easily exploited sources. The ancient Romans used hot springs to heat baths and homes, and similar uses are still found in Iceland, Turkey, and Japan. The true source of geothermal energy is believed to come from radioactive decay occurring deep within the earth.

In our days, mining for resources is inevitable. The resources we need are valuable in everyday life. Such resources mined up are coal, copper, gold, silver, and sand. However, mining poses environmental risks that can degrade the quality of soil and water, which can end up effecting us humans if not taken care of and many of the damages are irreversible once they have occurred.
