Summer Assignment: Toxin And Chemicals

When Rachel Carson's Silent Spring was published in 1962, it generated a storm of controversy over the use of chemical pesticides. Miss Carson's intent in writing Silent Spring was to warn the public of the dangers associated with pesticide use. Throughout her book are numerous case studies documenting the harmful effects that chemical pesticides have had on the environment. Along with these facts, she explains how in many instances the pesticides have done more harm than good in eradicating the pests they were designed to destroy. In addition to her reports on pesticide use, Miss Carson points out that many of the long-term effects that

Carson’s primary argument is that the ecosystem is unable to adjust and rebalance itself due to the rapidity of the introduction of chemicals into the environment. She points to the common knowledge that it took hundreds of millions of years for life to evolve to its current state. She goes on to explain how, given time (eons), the environment adjusted to natural dangers such as radiation emitted from certain rocks and short-wave radiation from the sun, but that it is impossible for the earth to adjust and rebalance in the face of man-made threats in the relative miniscule timeframe of decades. Her appeal is both logical and emotional. Logically, chemicals sprayed on croplands, forests or gardens will kill not just “pests” but other living organisms, and that some amount of these chemicals will end up in ground water, causing problems for anyone or anything that depends on this water. Emotionally if the possibility of permanent gene damage, which cause deformities, cancers, and early death, is not enough to encourage a second look at this issue then there is no hope for the planet’s future.

Rachel Carson is a noted biologist who studies biology, a branch of science addressing living organisms, yet she has written a book called Silent Spring to speak about the harmful effects of pesticides on nature. Carson doesn’t write about birds’ genetic and physical makeup, the role of them in the animal food chain, or even how to identify their unbelievable bird songs, yet strongly attests the fight for a well developed environment containing birds, humans, and insects is just and necessary. To Carson, the war for a natural environment is instantly essential for holding on to her true love for the study of biology. Thus Carson claims that whether it be a direct hit towards birds or an indirect hit towards humans and wildlife, farmers need to understand the effects and abandon the usage of pesticides in order to save the environment by appealing to officials, farmers, and Americans in her 1962 book, Silent Spring. She positions her defense by using rhetorical devices such as rhetorical questioning to establish logos, juxtaposing ideas, and using connotative and denotative diction.

In her essay Rachel Carson targets anyone who will listen as her audience. She wants to inform human beings of the effects chemicals have on the environment. Rachel Carson’s audience had little knowledge of the effects radiation and pesticides might have on nature or to themselves. She successfully enlightened her audience to the harm man was causing to the environment not only presently, she also wrote of future ramifications. She predicts “Future historians may well be amazed by our distorted sense of proportion. How could intelligent beings seek to control a few unwanted species by methods that contaminated the entire environment…?” (Carson 615). This statement might make her audience scrutinize their actions through the eyes of future generations.

Furthermore, the preceding statement supports Carson’s intention to present an informative, persuasive, and logical point of view without shocking or confusing the reader. Carson presents the problem calmly in the opening paragraph and states her claim as a practical approach to stop or decrease the amount of the spraying of DDT pesticides in combined efforts to stop the super races of insects like mosquitoes for example from becoming immune. Including this support for her thesis Carson argues mosquitoes becoming immune to the man-made vaccines presently available would inarguably have serious, detrimental and adverse negative impacts upon the effectiveness of the

Although people are well intentioned in their use of pesticides, people are ignorant of the harmful effects of them. Carson uses appeal of to pathos and logos to convey his point. Carson describes in the passage that while people are trying to kill weeds and insects, as a consequence of that we are in return hurting our ecosystem. She states, “ to still the song of the bird and the leaping of fish in the stream, to coat the leaves with a deadly film, and to linger on in soil all this intended target may be only a few weeds or insects”. This quote in the passage is used to appeal to the reader’s sense of emotion by making the reader feel a sense of responsibility. Although people easily kill bugs and weeds, they would never think that it would

(Carson para 11) “All this is not to say there is no insect problem and no need of control. I am saying, rather, that control must be geared to realities, not to mythical situations, and that the methods employed must be such that they do not destroy us along with the insects.” I think in her other paragraphs she did not refute them effectively. I feel that she could have said more and have a lot more information than what she had said. I think Carson had two sides, just like how there are two sides to every story.

In 17 chapters, many of which can stand alone as essays, Carson develops a deceptively simple premise: the use and overuse of synthetic chemicals to control insect pests introduces these chemicals into the air, water, and soil and into the food chain where they poison animals and humans, and disrupt the many intricate

I think we should definitely use insecticides to try and get rid of all the insects that can be

Carson explains that “as the habit of killing grows” more and more wildlife become direct targets and are subject to death by the pesticide companies. By describing the action done by pesticide companies and farmers as a habit, Carson elicits anger by making the killing seem consistent and purposeful. She suggests that the killings completed by pesticides are more direct to wildlife rather than being incidental. Carson also explains how farmers are using this deathly parathion “to ‘control’…birds distasteful to them”, depicting the farmers and companies as being merciless and cruel. Carson demonstrates that this unnecessary poison is not being used for their main purpose, which is to help crops and benefit farmers, but merely as a way to get rid of an “annoyance”.

“In 1956 the United States Forest Service sprayed some 885,000 acres of forested lands with DDT…to control the spruce budworm, but the following summer it had brought the most extensive and spectacular infestation of spider mites in history… There had been similar trouble along the Madison River in Yellowstone Park in 1929, in Colorado 20 years later, and then in New Mexico in 1956. Each of these outbreaks had followed forest spraying with insecticides.” (P.143) As is illustrated in this chapter, spraying chemicals like DDT often causes an unexpected outbreak of insect pests, because such chemicals kill far more their natural enemies than pests themselves.

This book was focused on the concern of pesticides that industries, along with us as individuals, have been dumping (both knowingly and unknowingly) into water. Carson was concerned that the chemicals which the farmers spread on their fields, and even the chemicals we use in our homes (among others), in the end, might come back around and harm us. The beginning of the book tells a story of a place, that was once so beautiful, turned dead and ugly due to a “strange blight that crept over the area” and destroyed everything. Later in the book, she goes on to explain that chemicals, particularly one known as DDT, are the major cause of environmental damage and the near extinction of

Once implemented, the long-term economic costs of biological control will often be lower than alternative synthetic chemical controls because pesticides require repeated application for ongoing efficacy. Biological control agents often exhibit high target specificity, unlike pesticides which often result in non-target organisms being affected. Pesticides can bioaccumulate and biomagnify in the food chain and the chemicals can leach through the soil negatively affecting other organisms. Biological controls will continually target the pest while not affecting other potentially beneficial coexisting organisms. Unlike chemical controls, biological controls are self-perpetuating, and the pests upon which they are acting usually do not develop a resistance, or are slow to develop a resistance. With proper research and understanding, the natural occurrence of biological controls can make their use safer to humans and other organisms than that of synthetic

Rachel Carson played a pivotal role in shaping the Environmental Movement and American culture because of her honest, direct disclosure of the matters at hand. Although Carson was not the first person to make these scientific discoveries, she was able to radically change the way millions of Americans perceived the environment and the dangers of toxic chemicals to themselves through vivid, articulate, yet easily understandable language. For instance, in her chapter titled “Elixirs of Death,” she says “For these chemicals are now stored in the bodies of the vast majority of human beings, regardless of age. They

In today’s world, there are still chemicals used to kill off unwanted insects, on the contrary, it causes all types of problems to the environment near the toxic. It is killing off the beneficial insects such as ants that help get rid of chemicals in agriculture. Chapter 4 Visualizing Environmental Science and chapter 2 from Silent Spring both explain that toxics is a catastrophe that is not a win-win situation on both sides.
