Often times, when people consume produce products they don’t think to consider the process it took to preserve the produce from going bad or being consume by pests. “A pesticide is a chemical used to prevent, destroy, or repel pests. Pests can be insects, mice and other animals, weeds, fungi, or microorganisms such as bacteria and viruses” (United States Environmental Protection Agency, 2012). “A pest can by any plants or animals that endangers our food supply, health or comfort” (Delaplane, 1996). Pesticide is a broad term that includes things such as insecticide, herbicide, and fungicide. Most pesticides that are used contain chemicals that can be harmful to people, animals, and the environment. The Office of Pesticide Programs of the Environmental Protection Agency regulates pesticides in the United States to protect public health and the environment. All pesticides used must be registered with the EPA, and the agency requires a battery of scientific tests not only for every pesticide, but for every use of every pesticide. Some pesticides that people may be aware of are things such as cockroach spray and rat poisons. However, some common products we use are considered to be pesticides as well such as: disinfect cleaners, mildew cleaners and plant sprays.
“Ancient Romans killed insect pests by burning sulfur and controlled weeds with salt. In the 1600s, ants were controlled with mixtures of honey and arsenic. By the late nineteenth century, U.S. farmers were using copper acetoarsenite (Paris green),calcium arsenate, nicotine sulfate, and sulfur to control insect pests in field crops” (Delaplane, 1996). DDT was developed as the first modern synthetic insecticides in the 1940s. DDT was initially used to treat malaria, typhus, a...

...intensive exposure to a variety of pesticides, either from applying these chemicals or from harvesting pesticide-sprayed agricultural products. According to Toxics Action Center 2012, “Studies by the National Cancer Institute found that American farmers, who in most respects are healthier than the population at large, had startling incidences of leukemia, Hodgkin’s disease, non-Hodgkin’s lymphoma, and many other forms of cancer”.
In summary, pesticides are often considered a quick, easy, and inexpensive solution for controlling weeds and insects. However, the use of pesticide have its cons. Pesticides has been shown to contaminated the environment and have effects on human health and wildlife. Pesticide residues are found in soil, air, and in ground water. The best way to reduce pesticide contamination in our environment is to use safer, non-chemical pest control.
My initial observation was that simple conservation actions such as reducing the use of pesticides can achieve measurable improvements in habitat quality and environmental health. Herbicides are toxic to most mammals as well as to the beneficial insects that you want to encourage in your garden. Sometimes herbicides seep into the ground water; causing contamination of which the long term effects are not known. Herbicide application can also result in drift or movement in the soil, this endangers wanted vegetation nearby. Herbicides are used far too rampantly. Excessive use of toxic herbicides is used when not necessary and because most are not aware of the many other natural alternatives. We must find more ways to cut back on the use of chemical herbicides and change to biological weed control methods.
There are many issues regarding the raising and producing of various livestock animals, and the use of pesticides on various types of crops. The movie Food.Inc does a good job explaining these issues, but in a very biased way. It makes agriculturists look like terrible people, when this is not the case.
What is a pesticide?A pesticide is a chemical substance used to kill pests, especially insects. A pesticide is also refered to as a biocide. Most pesticides are applied in spray form but occasionaly you will see pesticides that are in powder or pellet form. Pesticides are used on a variety of things, anything from crops like corn, barley, and wheat, to plants like petunias, marigolds, and rhodadendrons, which are usually found in small gardens greenhouses, and even in your backyard.
The pesticides must be natural, and be part of the approved list established by the Organic Foods Production Act of 1990 (6). The crop must also be void of any prohibited substances for at least three years. The time limit is set to allow room for chemicals, which may have an effect on the crop, that may reside over time to become less abundant. This is only a pre-requisite to even have the crop to be considered organic, meaning that the crop may still fail the certification of being organic. The crop that is used is also prohibited from going through genetic engineering.
The author describes each chapter with a surreal narration. It begins with “A Fable for Tomorrow”, which starkly declares a bleak future of every U.S village if they erred to use pesticides. “The Obligation to Endure” describes the lack of public awareness and how it would become grievous. She justly reasons that if the public might suffer from long-term misfortunes due to insecticides usage, they have a right to know the facts. Felicitous “Elixirs of Death” describes the nature of insecticides in three apt words. Chemical structures of common biocides are explained in an uncomplicated fashion. A series of three successive chapters is dedicated to Earth and its components. These chapters include the closely inter-connected ecological cycles, existing in the water, mantle and soil horizons. Pesticide dispersal in soil followed by its access into the ground water table and the waterways is an inconceivable process. The book promulgates the escape of biocides from their place of application, and their integration into natural bodies. All her chapters thereafter revolve around the various short-term and long-term effects of biocides on the biosphere. Rachel Carson had stated countless dire cases wherein complete ecosystems faced annihilation. The influx of detrimental chemicals extended their reach over animals and plants, and were causing human mortalities as well. Humans are a part of
Due to her vast knowledge she obtained from the Pennsylvania College for Women (now Chatham College) in 1928, Carson highlights the immense challenges that mother earth faces in striking a balance between the pressures posed by humans with self-regulating nature’s ecosystem. She explains that during the Second World War the use of DDTs were prevalent in the wars and although they did not have a significant effect on human life, their current use have pushed them to affect both the human, wildlife and marine life. Significantly, Carson’s inspiration to write the book was a result of her friends concern of the decreasing bird population after authorities sprayed DDT in her hometown to control mosquitoes. During the same time, there were massive campaigns nationally against a dangerous pesticide that was being used to control the fire ant in the Southeast. Having been a science writer, Carson was well acquainted with pesticide research and had a moral and logical backing against her reasoning.
“(Silent Spring) spells out in memorable detail through out the book the effects of synthetic insecticides and herbicides on water, soil, plants, wildlife, fish and human beings. But in the book’s final chapter she suggests alternative courses of action for mankind —- a way out of this march toward death.” (Holmes, Pg. 123)
A question commonly associated with the word insecticides is, what are they? Well I have the answer, insecticides are chemicals that are used to eliminate insects. In the agricultural industry, insecticides are classified into different categories,and the most used is carcinogenic. A carcinogenic insecticide is a substance or agent producing or causing cancer. This is just one of the reason that I believe there are more cons then pros when dealing with a insecticide.. When I was a kid , I can remember my parents taking me and my brother an apple orchard and picking apples. I couldn't wait to eat them until I got home, but we couldn't eat an apple because of what insecticides could be on the apple
To help keep crops from being destroyed, conventional farmers use many methods such as pesticides, herbicides, and fungicides. Nearly 1 billion pounds of these chemicals are used every year (“pesticides”). Because of this excessive use, some scientists express concern that using artificial chemicals in the farming process could produce unhealthy crops. People who ate it over a long period of time could suffer from degraded health and stunted growth (“Organic Foods”). For example, in 1989, the EPA banned the use of Alar which was a chemical used to ripen apples (“Farming, Organics”). This chemical proved to be carcinogenic after causing tumors in mice after several laboratory tests (“Organic Food”). As a result of these findings there was a dramatic increase of the sales for organic food (“Organic Food”). Another study found that Atrazine (one of the most widely used herbicides in the United States) has the potential of being carcinogenic and reducing sperm counts in males (“Organic Food”). This was further proven when evidence was found that chemicals u...
...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.
damage was done by poisons that farmers used to kill insects. The worst poison was DDT.
Many consumers and farmers have discovered that living in an industrialized culture where the focus has become faster, bigger, and cheaper is not the best way to produce our food. Obsessed with productivity, the agriculture industry is reaping the negative consequences of creating an unsustainable environment for food production. Time and time again, the media captures stories regarding deadly bacterial contamination and dangerous pesticide contamination causing illness and death in our communities. The environment is also damaged and contaminated. This devastating trend, due to irresponsible farming practices as a result of the industrialization of the food industry, has become all too common.
As time has progressed, there has always been an overarching need for high amounts of crop production throughout the world. With the rapid rate of population growth, the need for crops and other sources of nutrients is only increasing. In order to meet these high demands and increase yields, farmers and other agriculturalists have started implementing the use of pesticides. These chemical mixtures are being used in order to prevent, destroy, repel or mitigate any pests from destroying growing crops. However, using pesticides on crops can create massive amounts of pollution, negatively affect an individual’s health, and can spark biodiversity loss within an ecosystem. According to Michael C.R. Alavanja, “Over 1 billion pounds of pesticides are used within the United States (US) each year and approximately 5.6 billion pounds are used worldwide”. With all this in mind, it is clear that pesticides should not be made available to farmers and agriculturalists, and should
Instead of using pesticides in farming a better alternative would be biological control. This is when a natural predator is released into the crop growing area as a result the number of pests can be reduced.
Pesticide is a chemical used to prevent, wipe out and control the pest problem in agriculture. The use of pesticides have become a common practice around the world, and used almost everywhere, such as agricultural fields, homes, park and school, and so on. Most pesticides are insecticides, herbicides and fungicides that have distinct purposes. Insecticides are used to control insects; herbicides are used to destroy plants; fungicides are used to prevent molds and mildews. Most commonly pesticides contain highly toxic chemical such as Acid copper chromate (ACC), Acephate and Chlorpyrifos, and so on. One of example of insecticides, Chlorpyrifos, sprays widely on a variety of food and golf courses in order to control pests in a cornfield. However, “Chlorpyrifos can cause cholinesterase inhibition in humans; that is, it can over stimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.” (EPA GOV) In the market has thousands of products are similar as Chlorpyrifos.
