Pesticides And Insecticides In Silent Spring By Rachel Carson

In the mid-20th century, farmers used a toxic insecticide named parathion in an attempt to control pests detrimental to their crops. Rachel Carson was a biologist who wrote pamphlets (Lear) on conservation and natural resources designed to inform people on the beauty of the living world. In an excerpt from her 1962 work Silent Spring, Carson calls upon the public to take action against the use of parathion by highlighting its catastrophic nature and vilifying the agricultural community for their negligence.

Carson speaks about the diminishment of us as a human being. With the amount of harmful pesticides we use without fully understanding its consequences, we are slowly killing our human race. When pesticides are sprayed on crops and insects, they end up getting into our bodies. Adopting the easy way of getting rid of insects is harming us in the long run.

How do CFCs or chlorofluorocarbons affect Canada’s Ozone layer. To answer this question we first have to understand chlorofluorocarbons and the earth's ozone layer. Chlorofluorocarbons are chemical compounds made up of three chlorine atoms. One fluorine atom and 1 carbon atom. There were many uses for CFCs ranging from, being used as coolants in refrigerants to propellants for aerosols to being used as solvents for dry cleaning. As CFCs are non- flammable and not very toxic we thought they were a revolutionary compound, but unfortunately CFCs were one of the leading causes for the depletion of our ozone layer. ozone is a type of oxygen, an ozone molecule consists of three oxygen atoms whereas a regular oxygen molecule only consists of two.

Everyday people all over the world try to improve the qualities of their lives. Nonetheless, they forget that what they do can have severe harms and damages on the environment and other organisms. In the excerpt “A Fable for Tomorrow” from the book Silent Spring, Rachel Carson describes the disastrous and horrific effects of pesticides on the environment and animals of the town. In the essay “Our Animal Rites” by Anna Quindlen, she shows the inhumanity of animal hunting by human. Furthermore, she argues how human migration is destroying the natural habitats that belong to the animals. In the excerpt “Reading the River” from the autobiographical book Life on Mississippi, Mark Twain describes how he loses the ability to perceive the

In the book Silent Spring, Rachel Carson’s main concern is the widespread use of synthetic pesticides and their impact on the environment. Carson concentrates on a commonly used pesticide in the 1950s called DDT. She opposes the indiscriminate spraying of DDT because it has profound consequences on the environment, humans and animals. Carson collected information about how the DDT can cause cancer in humans, harm animals such as birds and remained in the environment for long periods of time. Subsequently, the chemicals in the pesticides are extremely harmful so she tries to raise awareness and convince others that there are better alternatives.

The topic of sustainable development has been a pressing and sustainable issue pertaining to environmental politics for several decades. The federal government of Canada has acknowledged the issue of globalization and

CFC is the abbreviation for chlorofluorocarbons which is a group of compounds that are made of carbon, chlorine, and fluorine. They are “Descendants” of methane and ethane and a subdivision of CFC is HCFC which incorporates the element of hydrogen. They are frequently utilized gases in refrigerants and aerosol propellants. About 80% of Canada’s stratosphere has been depleted because of CFC. Chlorofluorocarbon is a pernicious substance towards earth’s ozone layer because chlorine atoms are discharged when unprotected against ultraviolet radiation. Hence, it is being constrained at a high degree to prevent further ozone depletion.

To a certain degree, Carson’s writing is charitable to those it criticizes. Carson explains the pesticides notably DDT and a group of related insecticides that came into wide use after WWII. I think she has some charity but lacks much of it. She acknowledges the various reasons the insecticides are used because she says they are used to effectively controlling insects that damaged food crops, transmit diseases, and were just large pests to human society. She sort of emphasizes that she did not write the book to discredit the chemical pesticide industry but to inform people about the unintended consequences that came with the use of pesticides. She explains the situation, giving the opposing view (the reason the pesticides are used), but she

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

Scientists all over the world have been widely researching to find out ways in which the ozone layer is being destroyed through human actions. The ozone layer is gradually being destroyed by ozone depleting chemicals. These chemicals include chlorofluorocarbons (CFCs), hydroflourocarbons (HFCs), methyl bromide, halons, methyl chloroform and carbon tetrachloride among others (Ryding 173). These chemicals are used locally in coolants, fire extinguishers, solvents, pesticides, aerosol propellants and foaming agents.

In 2005, the World Summit on Social Development globally announced three areas that help define the philosophy and social science of sustainability in the environment. Represented as the “three pillars” which result in strengthening sustainability; Economic development, social development, and environmental protection became the global focus for balancing ecology and the environment today.

Hairspray. Refrigerators. Air conditioners. These everyday luxuries, while making human life more comfortable, are taxing our health seriously. Clorofluorocarbons, or CFCs, are anthropogenic chemicals used in refrigerants and as propellants in aerosols. CFCs, also known as freons, are also the primary culprit behind the depletion of stratospheric ozone, which allows harmful ultraviolet rays to reach the Earth and its inhabitants.

* Chlorofluorocarbons (CFCs) - harmful to the ozone layer emitted from products currently banned from use.

Chlorofluorocarbons (CFC’s): CFC’s are lowering the average concentration of ozone in the stratosphere. “Since 1978 the use of CFC’s in aerosol cans has been banned in the United States, Canada and most Scandinavian countries. Aerosols are still used around the world and accounts for 25% of global CFC’s use”. (Miller 448). Spray cans discarded or leaking refrigerator and air conditioning equipment and the burning plastic foam products release the CFC’s into the atmosphere. Depending on the type, CFC’s stay in the atmosphere from 22 to 111 years.” Chlorofluorocarbons move up to the stratosphere gradually over several decades. Under high energy ultra violet (UV) radiation break them down and release chlorine atoms, which speed up the breakdown of ozone (O3) into oxygen (O2). Chlorofluorocarbons, also known as Freons, are green house gas that contributes to global warming. Photochemical air pollution is commonly referred to as “smog”. Smog is the contraction of the words smoke and fog, smog has been caused by water condensing on smoke particles, usually from burning coal. With the introduction of petroleum to replace coal economies in countries, photochemical smog has become predominant in many cities, which are located in sunny warm and dry climates with many motor vehicles. The worst episodes of

Another controversial application of fluorine is its use, along with chlorine and carbon, in chlorofluorocarbons. As noted above, CFCs have been used in refrigerants and propellants; another application is as a blowing agent for polyurethane foam. This continued for several decades, but in the 1980s, environmentalists became concerned over depletion of the ozone layer high in Earth's
