Through research on the risks that come with uranium and coal for energy plants, there can be determination of which among the two is better for human sustainability.
Green house gases
Electricity plants that use coal for electricity production release large amounts of greenhouse gases and other pollutants that are harmful to the environment, bearing that coal is packed with high levels of hydrocarbons. Among these gases is sulfur dioxide that results in acid rain formation and consequent depletion of environment and even property that is reactive to sulfuric acid. Nitrogen oxides are also produced and together with VOCS result to smog formation. Mercury is also produced alongside Carbon dioxide which are direct contributors to negative climate change (Matthews, 2012).
On the other hand, in the nuclear power plants there is no production of gases such as nitrogen oxides, sulfur oxides, carbon dioxide, mercury or such other toxic gases. If nuclear power plants are managed properly they do not have a direct contribution to climatic change (Lamb & Brain, 2010). There is however release of water vapor into the atmosphere from cooling towers found in these nuclear plants. In coastal plants, there can be discharge of the heated water into lakes and seas and eventually the released heat can be radiated back into the surface causing heating. If temperatures of water are raised there can be alteration of carbon dioxide exchange with...
Nuclear power plants produce radioactive waste of about 20 metric tons each year which can be isolated and taken to remote areas for storage where they can stay for many years.
Nuclear power plants are therefore safe under ideal conditions. Climatic change that is caused by green house gases is a very crucial problem to be considered while deciding on which source of energy to be tapped. Therefore, nuclear energy source is better as compared to coal when it comes to the environment. The results from the research conducted are therefore in line with the hypothesis in that nuclear power has been established to be more human sustainable as compared to coal.

It is clear that if we as a species are to survive the 21st century and beyond, we must concentrate on changing our approach to the environment by reducing our carbon "footprint" and exploring the idea of renewable energy sources that will be appropriate for a growing global population. The Turning Point -- Transition to Renewable Energy -- the bleak reality is that the age of oil has dominated global
Instead of analyzing the innate meaning of these examples using a structured technique, Chomsky argues that it is only through subconscious knowledge of transformational grammar that one can truly understand the deeper meaning of language. Of course, this theory has been challenged by many with its emphasis on syntax and lack of focus on semantics, but as Chomsky himself said: But the fundamental reason for [the] inadequacy of traditional grammars is
Energy Sources: Energy Source Fuel (Coal)/Uranium Needed (tons) CO2 Emissions Sulfur Dioxide and Other Emissions (tons) Radioactivity mSv (millisievert) Solid Waste (tons) Accidents Coal Increased global warming and health effects. Nuclear Explosions Coal power plants and nuclear power plants are currently the two basic sources of electricity generation across the globe. The purpose of this lab animation and report is to evaluate which of these sources of energy is better for human sustainability. The determination of the more efficient of these
alternatives to traditional fossil fuels, and evaluate them based on their relative availability, renewability, and known environmental impacts. We begin with a baseline characterization of fossil fuels, and outline some of the factors contributing to their current market and industry dominance. We then examine three of the current most prominent and viable renewable alternatives to fossil fuels, including the controversial nuclear energy technology and two emerging technology areas, wind
Health Fitness Human Performance One of the most important parts of an athlete's training regime is nutrition because of its role in human performance. Athletes need to focus on nutrition because the failure to ingest adequate calories can contribute to a lack of vital macro and micro nutrients. Moreover, nutrition is a crucial element in any athlete's training regime given the influences of food on a person's physical mankind. Throughout history,
Energy in the United States In terms of total use in the year 2010, the United States was the second largest consumer of energy (Barr, 2012). After Canada and a couple of small nations, the United States comes at the seventh position in the per capita energy consumption (World Resources Institute, 2001). In this energy consumption, the energy that is used overseas for the production of the retail goods used in
