(1) People use high tech gadgets like cell phones every day, “cell phones seem to be carried everywhere we go” (4), but people don’t seem to realize the harmful effects on their bodies or on the environment. Cell phones have not only been noticed for their awesome applications and capabilities, but for their harmful attributes as well. Although cell phones have beneficial capabilities; the harmful effects are greater. One of…

of our planet. Like the other two effects of the urban sprawl, pollution is mainly caused by humans. It is a byproduct of burning coal because when coal is burned, it releases harmful chemicals like sulfur, lead, mercury, chromium, arsenic, and cadmium. These chemicals can cause sickness, chronic illness, and death to any organism that comes in contact with it. The catalytic converter that was discusses earlier is the fix we currently have for car emissions. Clean coal is how the United States…

Introduction Lead (Pb) contamination is a pervasive issue in many low-income neighborhoods throughout the United States. The toxicity of lead poses significant risks to human health, and proves to be especially harmful for children in terms of cognitive and physical development. Lead in the environment is primarily related to a legacy of anthropogenic sources including leaded gasoline, leaded paint, and various industrial applications. Although the presence of heavy metals is ubiquitous in the…

In recent years, there has been an increasing concern about whether or not should factories keep using fracking as their main method to extract oil and gas from the underground. Fracking, or hydraulic fracturing can be defined as the process of drilling down into the Earth and injecting high-pressurized water mixture into the ground, creating cracks in the deep-rock formations and allows oil and gas to flow out of the wells. According to The United States Geological Survey, wastewater disposal…

Lars Lindgren BIOL 3416-508 Common Arguments Against and in the Support of GMOs The policies surrounding genetically modified organisms, or GMOs, are one of the most divisive issues in biotechnology and genetic engineering as genetically modified crops directly influence today’s two main areas of current controversy: the environment and the economy. Criticism of environmental conditions are regularly based off the idea that “natural” is better. Besides the given premise that GMOs are…

constituent atoms. The experimental setup used in the present study is described elsewhere [21]. CdO thin films with different Cr- doping concentrations were deposited on ultrasonically cleaned microscopic glass substrates. The appropriate quantity of cadmium acetate dihydrate {(CH3 COO)2 •Cd•2H2O} was measured to make a 0.05 M solution by dissolving in 50 ml of deionised water and methanol in 1: 1 ration. The required amount of Chromium trichloride hexahydrate (CrCl3 • 6H2O), depending on the…

INTRODUCTION Hypothesis: to establish whether organic foods are worth the money we spend on if and how health, environment and economic factors influence our decision. Research Question: Organic foods. Why bother? Aim: To institute the fact that organic products are healthier than conventional products. The difference between farming methods and which method is more convenient. To establish whether Organic food is a passing FAD and to understand the effects organic food has on health,…

On January 12th 1962, the US Air force launched Operation Ranch Hand.
