Chloe Mott Block 2A November 15, 2011 Ignorance is Lethal Rachel Carson, a biologist, wrote a book entitled Silent Spring that helped change American’s attitudes about their environment. In the Silent Spring passage Carson describes how farmers rid themselves of vexing or inconvenient creatures, a majority of them being birds. The farmers kill the birds by spraying a poison called parathion, which is capable of “protecting” the area in which it is administered for extended amounts of time. In the passage, Carson provides all three types of rational appeals-ethical, logical and emotional- in an effort to raise awareness and encourage action about the issue of using poisons that have the potential to kill animals. She expresses these appeals by using various rhetorical strategies such as diction and syntax.
The Silence of the Limpkins by Susan Cerulean is about the overall degradation of Wakulla Springs. This story begins with the narrator describing how his colleagues and he have to put herbicide in Wakulla Springs every so often. As to clear the hydrilla, a plant imported from India because of a trade that overall massively impacted the Wakulla Springs ecosystem. “Hydrilla was imported to the United States from India for the indoor aquarium trade in the 1950’s. No one knew it would become a major invader of Florida’s lakes and rivers” (Susan Cerulean).
Petrina Chan Hr. 2 Due 9/19/11 “The Birds” Questions 1. Yes, I do think that “The Birds” was suspenseful. Sometimes, the author left you wondering what was happening outside of the house while the family stayed locked inside the house. Not for a few pages did she reveal that the birds had killed the Triggs and the mailman.
Sadly because corn is not in the normal diet for these animals it can and it is harmful not only to the environment but also on human health. Pollan who was informing us of all this information then goes on to say the feces from the animals at the immensely large farms can in fact pollute water supplies of the surrounding areas. The film then goes into a truly touching story from a lady named Barbara Kowalcyk, whom is extremely passionate about food safety, because her 2 year old son had been infected with E.coli and had sadly passed away. Barbara was followed throughout the film while she was working to get a law passed, Kevin’s law, for
Carson – Silent Spring RA Final Draft The 1960s were a tumultuous time, full of change not only in America, but throughout the world. Many environmental movements were present during this time of mass demonstration in America. One notable environmental argument was that against pesticide use. In this excerpt from noted biologist Rachel Carson’s book Silent Spring, the author uses various rhetorical terms to both denounce and vilify the use of parathion, a pesticide, declaring that the environmental effects are far more destructive, widespread, and detrimental than was previously thought. Through her use of evocative diction, Carson is able to illustrate the widespread effects that parathion can have in language that is both strong and easy to understand for the reader.
b) Halons are a group of chemical compounds with one or more halogens linked making them a type of organic halide. Halons were key ingredients to certain aerosol sprays such as deodorant and hair spray. The elimination caused manufacturers to alter the chemical makeup of the sprays, and quite frankly turned me to using solid deodorant as opposed to aerosol sprays. c) Carbon tetrachloride is one of the most potent hepatotoxins, meaning it is very harmful to the liver. This compound was once used as a pesticide for killing insects in stored grain.
The horsefly is the one that keeps most of the disease carrying bugs off the flapenguin. Without the horsefly, the flapenguin would get infected with the diseases because the horsefly is no longer around to keep the bugs off. Then there would be a few flapenguin in the

Santos explains that the environmental issues “date back to the nineteenth century, when trappers, fishermen, and naturalists campaigned against the unrestrained exploitation of American’s pristine environmentals,” (Santos, 1999). Can we really give a date that this became a problem? All we know is that it has been an issue for many years. Most Americans do not realize that pollutants can harm our senses like sight, smell, and even taste. It can also cause health hazards.
Parasites In the UK, food poisoning from parasites is rare. It is much more common in the developing world. Toxoplasmosis is the most likely cause of parasitical food poisoning in the UK. It is caused by a parasite that is found in the digestive systems of many animals, particularly cats. Humans can get toxoplasmosis by consuming undercooked contaminated meat or food or water contaminated with the faeces of infected cats.
