Plant pathogens and diseases

that organic livestock are treated more humanely and without the use of any medicines or steroids. The anti-organic campaign says that organic companies do indeed use chemicals that are harmful, that the manure used in organic growth carries larger pathogen contamination,…

coli O157:H7 was first recognized only eleven years prior in 1982, therefore the pathogen was still not widely understood. Bob Nugent, President and Chief Officer of Jack in the Box was an example of how uninformed the population was about E. coli. He himself was unfamiliar with E. coli and the effects it has on individuals who consume…

Also, she presents two Purdue scientists, Professor Huber and Professor Johal, who claim in a paper written in 2009, “the widespread use of glyphosate… can significantly increase the severity of various plant diseases, impair plant defense to pathogens and disease and immobilize soil and plant nutrients” (45). These testimonies promote her claim that GM foods have safety issues. Likewise, she employs facts into her argument to support her claims. For example, she states, “The first GM crop…

1. INTRODUCTION By 2050, it is expected that the current global population would have increased by more than 50%. The countries with the greatest population growths ( Figure 2) are also situated in areas with the least availability of fresh water ( Figure 1). These countries are also predominantly poor and cannot implement expensive water retrieval and treatment methods. This results in great economic stress on wealthier countries. This report will provide information on the current water…

Different gene silencing methods are being used in biomedical research for the development of potential disease therapeutics. Most of these methods are similar in that they involve the disabling of mRNA by preventing it from being translated into a protein. They differ in the type of molecule used to disrupt mRNA. Due to these differences, each silencing method has specific advantages and disadvantages. Two of the most currently understood methods of gene silencing are RNA interference…

Due to the small, congested space where the animals live in industrial meat factories, it is easy for various diseases and bacteria to spread, such as bovine spongiform encephalopathy, also known as mad cow disease, E.Coli, and salmonella. For example, the Angell Animal Medical center website states that chicken sheds called “grower houses” confine up to “20000 chickens at a density of approximately 130 square…

"Americans now spend more money on fast food than on higher education, personal computers, computer software, or new cars. They spend more on fast food than on movies, books, newspaper, videos, and recorded music – combined" (Schlosser 3). Many Americans nowadays eat out more often in many fast food chains such as McDonalds, Burger King, and Carl's Jr. However, many do not realize the horrid ramifications that can impact one's life Esteemed writer Eric Schlosser is a current-day American…

in the year 2001 presented by Foley, took note of “[how] toad embryos appeared to be dying because of a chain of events that led to climate change”. “The climate change-induced increase in various lethal diseases affecting a wide range of organisms may explain the recurring theme of epidemic disease associated with many amphibian declines” said head researcher, Todd McNeil at the University of Oregon. It has become increasingly clear that if climate change may translate into species losses are…

In Rewilding Our Hearts by Marc Bekoff (2014), he addresses how humans can change their ways to contribute to the restoration of environments damaged by human action or lack thereof. He argues that though there has been a paradigm shift in the ways in which we perceive animals has changed through beginning to see non-human animals as sentient beings (Bekoff 2014, pg. 1), there is still more change that people must become more involved with. And that is to save the ecosystems and provide…

coli, Cryptosporidium, and fecal coliform, which can be 10 to 100 times more concentrated than in human waste. More than 40 diseases can be transferred to humans through manure.(Facts about Pollution from Livestock Farms 2013)” Also, “Large hog farms emit hydrogen sulfide, a gas that most often causes flu-like symptoms in humans, but at high concentrations can lead to brain damage…
