Stewart Negron At this point in time, the world has reached a point of no return climatically and the impacts of “Global Warming” are inevitable. Given current atmospheric research, climate change is proven to be a true, unnatural feedback caused by human activity. Due to the medias selective exposure of climate change information, specifically of the skeptic views of the topic, society has not grasped global warming as a current and vital issue. Additionally, the refusal to join climate…

Algal oils are similarly unlikely to be economic; the cheapest form of cultivation is in open ponds, which then requires a robust, fast-growing alga that can withstand contaminating bacteria and protozoa and gain an oil content of at least 40% of the biomass. No such alga has identified yet. However, if the prices of the major plant oils and crude oil continue to rise in the future, just…

Until recently it was believed that the earth had only experienced 4 to 5 glacial periods, all of which occurred in the past 2 million years. (Louis Agassiz, 1837) However, globally conducted research has revealed that countless glacial advances have appeared over 200 million years ago, thus broadening our insight of the history of the earth system by 100 times. These astonishing advances have witnessed the introduction of a new sub-discipline—palaeoclimatology, which specialises in the study of…

repercussions, for example fossil fuels or nuclear energy. Alternative energy sources are renewable and are thought to be "free" energy sources. They all have lower carbon emissions, compared to original sources used before as well as now. These include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, Hydroelectric Energy sources. Incorporated with the three…

Sources At the beginning of the 21st century, mankind started using new technologies in order to harvest energy from environmental sources other than fossil fuels and natural gases. These environmental energy sources include solar, wind, water, biomass, and geothermal. These sources are more commonly known as renewable energy sources. Renewable energy is a theoretically inexhaustible energy source. It is an energy source that is not depleted when used. A good way to look at a renewable energy…

Environmental Pollution Environmental pollution is introduction of contaminants into the environment that cause adverse change. Pollution can take many forms, some being, chemical substances or energy. Noise, heat, and light are also known as pollutants, pollutants are are components of pollution. They are often seen as foreign substances or energies and naturally occurring contaminants. National income and level of development are critical factors for the differences in pollution types and…

“Switchgrass is a very native perennial warm season grass with the ability to produce moderate to high biomass yields on marginal lands. These characters have resulted in the use of switchgrass in several Bioenergy conversion processes, including cellulosic ethanol production, biogas, and direct combustion for thermal energy applications.” (Carter, Jimmy 1) Switchgrass produces cellulose, when cellulose is broken down and ferment it, then becomes cellulosic ethanol which can be used to fuel…

Ozone is a naturally occurring molecule containing three oxygen atoms. Ozone molecules form a gaseous layer in the stratosphere, 15-30 km above the surface of the earth called the Ozone layer. It protects life on earth by absorbing harmful ultraviolet (UV) radiation from the sun. Today the ozone layer is depleting due to the release of pollution containing chemicals chlorine and bromine. Such deterioration allows large amounts of UV B rays to reach Earth1 seen in figure 1, which can cause many…

trains, and taxis. They have a lot of subways all over the place. Trains and subways are the main source of transportation. The trains are powered off of electric energy. Energy in Rio is 82% hydroelectric, 3% is nuclear, 5% is natural gas, and 8% is biomass. So that means that pollution is not really made of energy. The houses and buildings are powered off of that. On some houses you will see solar panels on the roof. The pollution in Rio is unbelievable!…

Nuclear energy is produced by nuclear fusion which consists of splitting an atom in two, which creates a mass that then turns into a large sum of energy. The reaction is controlled and the energy is harnessed. In the United States alone, there are around 61 nuclear power plants, and in total they produce 20% of our electricity. There have been numerous of points about nuclear energy that have been weighed and discussed over the years. Whether or not nuclear power plants are indeed safe, the…
