Nuclear power plants do not emit the harmful green house gases and other negative by-products associated with the more conventional systems fuelled by coal and natural gas. Nuclear power plants use nuclear reactions to drive their generators. The reactions produce extreme amounts of heat that must be managed. Most nuclear installations use water to control temperature and vent steam into the environment. This is a much cleaner excretion than that of conventional power plants (Kidd).
Although at first glance nuclear may seem like a perfect solution, the nuclear industry does produce some nasty pollutants of its own. Nuclear reactors require fuel rods made of radioactive materials to function. The fuel rods can be used for long periods of time; however, eventually they become spent and can no longer be used in the reactors. Fuel rods remain radioactive even after they have been used in nuclear power plants. When the nuclear reaction is complete the fuel rods are removed while they are still very hot.
Spent fuel rods are then placed in large tanks of water to cool. The rods are kept in the tanks for five years; during which time their radioactivity and temperature greatly decreases (Chapin et al.). They are then transported to permanent storage facilities in high strength containment vessels. Some people w...

- Written by Michael Pollan, this book is his perspective of human nature in relation to plants. He theorizes that Nature’s creation symbolize our emotional and physical desires. Pollan uses four plants to prove his theory: Apples, Tulips, Marijuana, and Potatoes. Apples, Pollan explains, mirror every human’s desire for sweetness. He writes of Johnny Appleseed (John Chapman), a man who planted apple trees all across America. He explains that Johnny Appleseed was not mythical or legendary, but that he was a real person who, like any other man or woman, had a desire for sweetness.... [tags: Plants]

- The scientific field of the biological control of alien invasive plants (AIP) has developed rapidly over the last 100 years in various countries (Morin et al. 2013) but, are some countries performing better than others. Biological control looks to diminish the negative consequences of alien invasive plants. For example, biological control reduces alterations of biotic and abiotic processes produced by AIP occurring within the ecosystem (Richardson and van Wilgen 2004). Major sites of invasion like the United States of America, South Africa, Australia, New Zealand and Canada have therefore been at the forefront of scientific progress in the field of biological control (Julien and Griffiths 19...

- Before targeedt genome engineering emerged there was classical plant breeding and transgenic methods to modify crop plants, and ensure sustainable production. Researchers today have utilized methods like zinc finger nucleases (ZNF) and TAL effector nucleases (TALENs) to create these improved crop plants. Recently, a new method has caught the eye of many researchers; a method that simplifies the process and saves labor: CRISPR-Cas9 system. This method of genome engineering is particularly interesting not only for researchers but also for millions of Americans.... [tags: CRISPR-Cas9, genome engineering, plants]

- Intense grazing by herbivores can drastically affect the amount of seaweed present. Having secondary metabolites can be used as a defence mechanism. Many different genres of algae were studied, having many different types of chemical compounds found on many different parts of the world. Most studies harvested and purified samples then exposed these samples to different herbivores. The herbivores varied in size from large fish to smaller organisms such as amphipods. Aspects such as survivorship, behaviour and chemical composition were analyzed.... [tags: herbavores, plants, science,]

- Asian American, Who Left Out from the debate What will be your first thought when you hear the word “undocumented”. Immigration issue, especially undocumented immigration issue is always framed as Latino issue. On the contrary, Asian immigrants are often left out of this discussion. As the matter of fact, Asia is now the largest sending region for immigrants. Asian Americans are the fastest-growing immigrant population in the United States today. They are expected to become the largest immigrant group in the United States (Foley 16).... [tags: Asian American, United States]

- For many year, the death penalty has been widely debated throughout the United States. We as a country are divided on this topic; half believing it is unjust, unconstitutional, inhumane, and cruel. The other half believing it is morally just and constitutional. Those thinking it is cruel want capital punishment abolished. The others want to see it revised and maintained. Capital punishment is being sentenced to death and executed for committing various crimes. Usually, it is reserved for convicted murder cases, but had been used for others such as: armed robbery, kidnapping, rape, and treason.... [tags: Death Penalty Debate]

- "Global warming is not a conqueror to kneel before - but a challenge to rise to. A challenge we must rise to." -- Joe Lieberman INTRODUCTION Global warming is a controversial environmental topic in today’s society. Global warming is when greenhouse gases (carbon dioxide, water vapor, methane, chlorofluorocarbons, perfluorocarbons, and nitrous oxide) act as a blanket that insulates the earth and prevents heat from escaping into space, which in turn causes the global temperature to rise....

- The death penalty is one of the most debated issues in the United States. It is a judicially ordered execution of a prisoner for a capital crime. There are many people who oppose the death penalty and then there are many people who support the death penalty. People who are against it think it is inhumane or it is too expensive. The people who are for the death penalty feel that it gives a chance for individuals to be accused for their wrongful acts. Each year billions of dollars are spent to sentence criminals to death....

- The concept of global warming has become one of the most widely debated and controversial topics of our time. Scientists learned long ago that the earth’s climate has powerfully shaped the history of humanity. However, it is only in the past few decades that research has revealed that humans have a significant influence on the climate as well. A growing body of scientific evidence indicates that since 1950, the world’s climate has been warming, primarily as a result of emissions from the burning of fossil fuels and the destruction of tropical forests....

- Montnana Plants & Native Americans Since the beginning of the human race mankind has depended on the natural resources in their environment for survival. They utilized the available flora to nourish their body, heal their wounds, comfort their ailments and to create products to ease their daily lives. Many of the same plants utilized thousands of years ago by the indigenous people have been integrated into modern day medicines. The scientific interest and knowledge of plants for nourishment, healing, and practical uses is called ethnobotany.... [tags: essays research papers]
