The excerpt from Rachel Carson’s Silent Springs explains how the human race has used their powers to alter the natural environment. These changes resulted in adverse effects, not only to organisms, but also to mankind. According to the extract, for many decades, life on Earth has been characterized by balanced interaction between the living organisms and the surrounding. The environment controlled the animal life habits and physical forms of vegetation. The situation has changed over time, and now people possess significant powers to change the environment. Human activities has increased to alarming levels in the past quarter century. Such powers have resulted in the contamination of the environment to a great extent: dangerous and even lethal materials are released into the air while others are disposed of in lakes and oceans, resulting in pollution. The pollution causes …show more content…
An example of this would be is the number of new chemicals that are released into the environment exceeds 500 in the United States alone; plants, animals, and humans are expected to cope with all these chemicals. Some of these chemicals are so strong that living organisms cannot tolerate them; therefore, they end up killing or negatively harming the organisms. Among the killer chemicals released into the environment are the pesticides and insecticides that are used in our daily lives, Rachel Carson asserts that they should be defined as biocides because they affect all forms of life. The constant use of chemical results in the application of Darwinian’s principle of the survival for the fittest: the most resistant organism emerges. People respond by developing deadlier chemicals that harm the environment further. To sum up, the increased use of the chemicals in the field of entomology has more negative impacts on the environment and life on Earth than the benefits it
The excerpt from “First muse” by Julia Alvarez is a story about her Dominican cultural background. Alvarez has been looked different based on her ability to speak English. Due to Alvarez not have a “Dominican education and her ability to speak English” bullied and teased. As a child Alvarez had told her mom that she does not want to just be the stay home wife who just cooks and cleans like every other wife she wants she does to be different, she wants to be more than just a stay home wife when she get older. It’s ok to know more than one language, but at the same time to should always stay truth to your cultural background/inherent. Just because Alvarez knows English does not make her a different Dominican girl because she knows Spanish too.
For example, a cow that is consuming intoxicating water the milk that is producing the humans are going to drink it and now is not only the cow being intoxicated, but the person consuming the milk. Leading to health issues, on top of that, pollution of the air because of the natural gasses the cars, truck, factories are thrown in the air. Ending with the person either getting really sick of intoxication or even death. The cow spreading this issue to everyone drinking milk and having the owner either to put him to sleep causing him to

Humans can not be the only thing that is hurting the Earth. When you really think about it, Earth goes through a lot of natural disasters, which cannot be controlled. According to an activist, Tim Haering, “Tsunamis, floods, volcanoes, earthquakes, tornadoes, wildfires, disease nature kills more than we kill each other.” Earth throws in all of these natural ...
There is no such thing as just changing something from one part and not having its effects distribute throughout the entire ecosystem. As an ecosystem continues changing and evolving, so will the organisms living around or in it. We must adapt to the environment or we will become extinct, unable to adapt into the rapidly changing environment we live in. Althout human impact on an environment may benefit us, it can also be harmful to nature. By taking care of what we do to the environment, we can prevent future negative changes in the environment and preserve earth’s natural state.
Early in history DDT was a very effective chemical that killed many parasites and stopped the mass spread of malaria. But the reward is not worth the damage that it does to the environment, especially in modern day where we have other ways to prevent parasite and diseases from getting to us. "Top of the Food Chain" by T. Coraghessan Boyle, is a story about the absolute absurdity of things that human beings do to their world and to their fellow living beings. Set during a Senate hearing by a chemical company executive on the defensive about the effects of DDT in Borneo. Basically, poison was used to get rid of mosquitoes. Didn't work. So they brought in geckos, that died from the poison. Cats ate dead geckos, and cats died. This brought on rat infestation. So they brought in more cats and cycle started over again. He is arguing that humans are wrong for destroying their planet with pesticides and other harmful things; this satirical piece effectively supports his argument.
In the article "The Obligation to Endure", an excerpt from "Silent Spring", Carson focuses on her major concerns with the environment. For millennia, Mother Nature was the lone modifier that possessed the ability to shape the environment. In turn, this caused species to adapt for survival. However, with the birth of man, the delicate balance has shifted. Humans now possess the ability to alter the makeup of their environment. This is a power that shouldn 't be taken lightly or abused. However, humans are often blind to corruption until it 's too late, and so the inevitable happened. Man abused its power and failed to see the consequences. This is an overarching concern of Carson, "The most alarming of all man 's assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials (Carson)." The chemicals dumped into rivers the pollution pumped into the air. The toxic radiation released from nuclear explosions in the form of Strontium 90. The endless pesticides sprayed on crops and trees. All of these are the weapons used in "man 's war against nature
Americans had knowledge of the events taking place during the war, but Carson shed a light on the ripple effects that the environment was experiencing. Silent Spring brings the focus to different threats that had arisen because of the war. In a way, Carson places the blame for the deterioration of the environment on mankind as a whole. In the past, wars had been fought without any use of nuclear weaponry. Carson’s writing really emphasizes the fault of mankind’s decision to hurt the environment. “Along with the possibility of extinction of mankind by nuclear war, the central problem of our age has therefore become the contamination of man’s total environment with such substances of incredible potential for harm – substances that accumulate in the tissues of plants and animals and even penetrate the germ cells to shatter or alter the very material of heredity upon which the shape of the future depends.” (Carson, 181). The writing technique Carson uses in Silent Spring has a way of making the reader feel guilty, especially considering that at the time of publication there was so much environmental destruction occurring. Carson’s writing helped to educate the American population of the harm to the environment caused by the Cold War. Because the war’s dangerous strategies provided such a strong backbone for Carson’s argument, the American public was very receptive of the content and themes presented in Silent
...ortation of plants, fruits, vegetables, and animals. Indiscriminate pesticide use kills the good with the bad. Long term and wide spread pesticide use poisons underground water sources, which, in turn, poison plants, animals, and humans. And, finally, by our uninformed actions, new super races of pests continue to evolve and create even greater dangers than the original.
and is existing surely because of humans themselves- overpopulation. “Overpopulation is the problem” and causes other externalities such as pollution, deforestation, and a greater handful of biodiversity losses. In addition, overpopulation causes economic and political factors such as more consumption per person and the reduction of resources that can be provided per person. This contributes to the strain on ecological systems and the economic and population growth. With overpopulation, many resources become finite and an umpteen amount of ecosystems are being destroyed. Overpopulation relates to the impact of humans on pollution. Obviously with more human life, there is more necessity for jobs such as factories that give off fumes, automobiles, and the use for burning fossil fuels. In greater extent, this leads to an environmental factor in that it accumulates chemicals in food chains such as mercury, arsenic, and copper. It can lead to political problems as well, when trying to interact with other countries and stop the problem of global pollution and eventually endin...
Rachel Carson’s Silent Spring revolutionized the American point of view concerning the environment. It rejected the notion that pesticides and chemicals are the right choice for “controlling” various animals that are seen as an inconvenience. Carson writes about the dangers of pesticides, not only to nature but man himself.
For instance, in Seeds of Death, Monsanto spread roundup, a pesticide, on their crops and realized a roundup resistance bacteria continued to grow. In response to this, Monsanto collected the bacteria and took a piece of its DNA to create roundup resistant crops. Although this seems like a good idea, it makes crops weaker and makes it easier for crops to be wiped out by a stronger disease. In addition to this, the pesticides also pull nutrients from the soil, therefore resulting in the microorganisms in the soil being killed. This, in turn, leads to the soil being filled with poison and also being infertile in the near future. The worst part about these pesticides is that once it enters the environment, it’s in the environment

Carson was the only environmentalist and the only woman featured in the entire issue. Evidently, her impact in the world of "scientists and thinkers" was a tremendous one, and, as mentioned in Matthiessen's Time article, her book, Silent Spring, is "nearly 40 years later . . . still regarded as the cornerstone of the new environmentalism."1 Matthiessen goes on to write that "one shudders to imagine how much more impoverished our habitat would be had Silent Spring not sounded the alarm."2 This is indeed a worthy claim by Mr. Matthiessen, but he correctly uncovers a bigger and more alarming truth when he says, "the damage being done by poison chemicals today is far worse than it was when she wrote the book."3 In fact, since 1962, pesticide use in the US has doubled.4
Efforts to improve the standard of living for humans--through the control of nature and the development of new products--have also resulted in the pollution, or contamination, of the environment. Much of the world's air, water, and land is now partially poisoned by chemical wastes. Some places have become uninhabitable. This pollution exposes people all around the globe to new risks from disease. Many species of plants and animals have become endangered or are now extinct. As a result of these developments, governments have passed laws to limit or reverse the threat of environmental pollution.
