Recommended: Effects of agriculture before and after pesticide
With our growing population scientist are trying to develop more and more ways to help sustain our food production to keep up. There are many insects and plants that are harmful to our crops. Pesticides and herbicides are developed so that we can safeguard our food production and keep up with our needs. Our reckless use of pesticides and herbicides are not doing as intended because of the evolution of bugs and other organisms that are resistant to them. nature is forever adapting to the challenges that we force upon it,it is a waste of time and resources fighting it.
In “The Obligation to Endure” by Rachel Carson, she talks about the widespread use of pesticides, and others like it, to kill everything from insects, weeds, and rodents. the chemicals in the pesticides are not just harmful to insects, but are in fact indiscriminate and are harmful to all beings that come in contact with it. the “pests” and “weeds” that they designed to kill are also food sources for other animal. some species are dying off because their food source is gone. Eventually, through natural selection, there is a species that forms a resistance to the pesticides. Everytime resistance is formed a deadlier
The Monarch Butterfly larvae only food source is the milkweed, which are considered a weed by most farmers and are being killed by the use of herbicides. Milkweeds are not just the food source for the larvae but it is also their home until they turn into an adult. Due to the use of herbicides the monarch larvae have lost both their only food and home, there has been a 90% decline of monarchs since the past 20 years. The monarchs are important species to the ecosystem because of their duties as a pollinator, they help pollinate many flowers in the wild. The herbicides are not just killing off a weed they are causing a species to die off from the face of the
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.
Monarch Butterflies and Butterfly Weed, a type of milkweed, have coevolved as plant and pollinator. This means that they both rely on one another to survive. Milkweed is the primary source of nutrition for monarchs. Monarchs only eat Asclepias tuberosa a particular species of Milkweed. The monarch relies on toxins in the milkweed to fend off predators such as birds. The toxic tendencies of the milkweed plants caused the government to attempt o eradicated the plant along roadsides and in cow pastures. This has caused a major decline in population of milkweed, which is also endangering monarchs. Milkweed relies on the monarch to pollinate it so that it can reproduce.
Crops today are thriving, and farmers can owe it all to the pesticides they use. If no pesticides were used, then insects would destroy crops, feeding off of their leaves and produce until hardly anything is left. According to corncommentary.com, Without the use of pesticides and fungicides, most fruit and vegetable crops would suffer a 50-90 percent loss due to uncontrolled insects and disease organisms. Despite what most people believe, even organic growers use pesticides on their crops that have been approved for such organic growers. Even they know that the wrath of insects and other disease organisms would destroy their plants and their profit they would have made from those plants. Also, without things such as weed killers, people would have to till the soil around their crops by hand. On large scale farms, this would take a huge amount of people to complete a task like this. The weeds would have to be pulled up, by their roots to ensure they wouldn’t grow back rapidly. On top of that, the crop would have to be routinely checked for weeds, as they grow fast and of many. The amount of money it would take to pay all the workers, and how often they would need to be paid for their work, is not owned by any farmer. Pesticides, herbicides and fungicides are what help keep our crops protected and healthy. Without them, we would be in deep
In the video, “Genetically Modified Crops: Hope vs. Hype”, reveals that a Cornell study followed-up by Iowa state researchers show that “pollen from GMO corn is killing the larvae of the Monarch butterflies, which is not at all what the corn 's designers intended” (“Genetically Modified Crops: Hope vs. Hype”). GMO seeds are contaminating our environment, which were presumed safe before. Genetically-modified organisms are the unorthodox procedure of moving genes from one species to a completely different and unrelated species. These unnatural transferring of genetics are causing death among insects. Undeniably, nature 's long-lived ways are safer compared to the bio-tech 's short-lived ways. They hold many uncertainties. Such as, Niagara
The history of life on earth could be thought of as a record of living things interacting with their surroundings; for most of history, this has meant that life molds over time by the environment it inhabits; however, very recently, humans have become capable of altering the environment in significant ways (Carson 49). Marine Biologist, Rachel Carson, in her environmental sciences book, The Silent Spring, documents the detrimental effects on the environment by the indiscriminate use of pesticides. Carson argues vigilantly in an attempt to persuade her extremely diverse and expansive global audience, under the impression that chemicals, such as DDT, were safe for their health, that pesticides are in fact detrimental for their health. Through
On the contrary, President Obama “unveiled a plan aimed at stopping the rapid decline in bee and butterfly populations” (“On May 19”). His plans are to reduce the death rate of bees which in turn will help out the agricultural production. He also plans to clear land in order to give the bees a bigger environment in which to repopulation and will ensure that no bees are harmed in the process (“On May 19”). The president sees the devastation that the decline could cause and is trying to combat the issue. The European Union has banned three pesticides in order to combat the decline but “have fallen short of providing adequate safeguards for the re-propagation of bee colonies”(“Bee research”). Governments are taking notice of the problem ahead yet still we are until to achieve the full support of all
To most, the honeybee can be an annoying insect that has a powerful sting. Yet, the honeybee is so much more than just another insect. The honeybee is arguably the most vital component in the development of our food crops. With roughly 90 percent of our food crops dependent on the pollination of our honeybees, our food system, agricultural development, and diet rest on the work and well being of these buzzing insects. Unfortunately, since 2006 there has been a major decline in the population of honeybees, and has gotten progressively worse because of colony collapse disorder. The first reported increase of CCD was documented in November 2006 in Florida. By February 2007, several states began reporting major losses associated with CCD, ranging from 30% to 90%. A little over a half decade later in 2012 the attention paid towards CCD has grown substantially with more research being done as CCD continues to get worse. The main culprit for CCD, as research has suggested, is the use of pesticides on our food crops. With major corporations such as Bayer making millions and millions of dollars in profit each year in the distribution of pesticides, it is no wonder that nothing is being done to stop this practice despite evidence linking the use of pesticides and the drastic deterioration of the health of honeybees. With the continuation of the use of deadly pesticides and the vital role bees play in the pollination and development of our food crops, both the environment and our economy will be effected directly and face the potential for catastrophic results.
A wise man once stated, “Earth provides enough to satisfy every man 's needs, but not every man 's greed.” -Mahatma Gandhi. Mahatma Gandhi was one of the wise people that realized we need to take better care of our home planet Earth. Another wise person who also thought the Earth should be taken better care of was Rachel Carlson. In 1962 Carlson wrote “The Obligation to Endure” in hopes to educate people on this matter. In this essay I am going to explain how Carlson’s ideas have changed since she wrote her book in 1962.
Others include birds, butterflies, and the wind; however, honey bees, by far, are the best at pollinating plants. Collecting pollen is their whole life’s purpose, according to Michigan State University’s article, “Native Plants and Ecosystem Services”. Over one hundred forty three million acres of plants in America are sprayed with a bee-killing insecticide that has been banned in Europe by the European Food Safety Authority (Sarich). Promote ecological farming, and ban all bee-harming pesticides.
...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.
With the world having so many people on it we use a lot of pesticides and fertilizers. If it was not for the help of these we would not have gotten to the place we are now. Pesticides and fertilizers do a lot more than just help grow and safe from pests. “Nearly 50% of the world labor is employed in agriculture and they significant risk”
LaJeunesse, S.. Common crop pesticides kill honeybee larvae in the hive. Penn State | News. 27 January 2014.
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
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.
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.
