Year after year the population of humans is increasing in many parts of the world. As the population increases the demand for food also increases. Farmers are responsible to provide the consumers with food and fulfil our wishes. When population increases more nourishment should be produced to feed everyone. The use of pesticide is an essential part to produce the food. Pests are the ones that reduce the amount of food farmers produce. DDT is the most popular synthetic chemical to kill weeds, insects, rodents, and other pests. The abbreviation stands for dichlorodiphenyltrichloroethane. It was first widely known in the 1950s and 1960s, when toxic effects of the insecticides were recorded. DDT was always known to be effective in human lives, but …show more content…
It can impact wildlife, environment, and human health to various extents. The major impact of DDT is directed on the aquatic life, animals, and birds. The tendency of DDT to concentrate in fats, animals, and wildlife has the ability to detrimentally affect organisms. DDT was originally used to fight off a disease called malaria. It was a parasite contained by mosquitoes that spread from person to person. Sir Ronald Ross proved this disease and was awarded the Nobel Prize in Medicine for his discovery in 1902. DDT was widely used to control mosquitoes. It was easy to use and effective. To avoid mosquitoes, people sprayed DDT on the walls and ceiling of their houses and public buildings. It was also used by farmers who sprayed it on their crop fields using airplanes or helicopters. The long term effects of DDT started to arise. The population of animals, birds, and fishes started to decrease rapidly. By the 1950s, biologists started to believe DDT was a culprit. When certain toxic substances
By the name of “superspecies” we try to change the world feature and control the nature with science. With science, a lot of technology has been invented to support people demand for products. Without anticipation about the bad consequences, sometime the invention is causing more damaged than it provide in later on. In 1930, DDT that use for killing insect was discovered by Paul Mueller, working for the chemical company Geigy in Switzerland. For this reason, the benefits of using DDT became immediately obvious (65). Years letter, the unbelievable side effect of using DDT was found. While Biologists investigated the decline of eagles and hawks, they discovered the hitherto phenomenon of “biomagnification”, which compounds gather as they are ingested up the food chain (67). DDT phenomenon proves that thinking like science is only to understand the world in separate pieces. It is lack of understanding the rhythms, patterns and cycles of the nature. Therefore, we need to think beyond the science to see the connections between us and nature because in the reality this world is the world of
The Baby Boomer generation and the time period has a lasting effect on the economy and the environment. The baby boom for the United States was similar to other countries after World War II. Several economies also blossomed, but overall with very little care for the environment. After World War II the use of industrial made chemicals increased in popularity throughout the United States and the world (The “New Environmentalism” OF THE 1960S). The chemical DDT was originally being used widespread to eradicate disease vectors, such as mosquito carrying Malaria ("The DDT Story."). DDT influenced more than just mosquitoes as it had lasting effects in the environment where it noticeably bioaccumulate in the food chain and caused high mortality in young bald eagles ("The DDT Story."). Rachel Carson’s book, Silent Spring released to the public in 1962 which is the time period in which environmental health and human health were connected (The “New
The pesticide DDT banned in 1987 was a detrimental to the environment leading to it to be banned in 1987. DDT remains in the soils for a long period of time. The chemicals affect the ecology of the soil and water run off causing contamination of livestock and native animals and aquatic species. Studies indicated a range of human health impacts from DDT including cancers, infertility, miscarriage and nervous system impairment. The social and economic impact of DDT use in viticulture was significant.
The purpose of this essay is to deal with the fact that chemical warfare should be brought back to modern warfare strategies. As Warren Rudman said, “And they will tell you unequivocally that if we have a chemical or biological attack or a nuclear attack anywhere in this country, they are unprepared to deal with it today, and that is of high urgency.” Rudman’s words are true in what they say and that we should do everything to counter-act his statement. Biological weapons are a key to outstanding success in war and therefore, I strongly suggest that chemical warfare is an effective and producible weapon tactic that can be used on today’s battlefield.
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.
Do you know what you're really voting for? Iowan farmer Reg Clause suggests you may not in his column, “Say ‘no’ to GMO labeling.” Reminding readers that general election day has come, he attempts to convince us that a certain law should be voted against. The proposed legislation would mandate all foods that contain genetically modified organisms, also know as GMOs, to display a warning label on their packaging. He argues that this would be detrimental to the good name of these types of foods when they do not deserve to be shamed. I agree that the genetically engineered crops should not be labeled, but not because that would tarnish their name. However, the reasoning for my opinion comes from the perspective that it would not only be impractical
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
When you eat a cheeseburger, you might know that you are eating a beef patty with cheese, lettuce, and ketchup on a sesame seed bun, but do you know what you are really eating? According to the documentary GMO OMG, “approximately 85% of all processed foods contain GMOs”, yet most consumers are unaware that this secret ingredient is included in most of their food. Although Monsanto believes their product is safely feeding the world, consumers should be aware of the hidden horrors of genetically modified food because research indicates that GMOs could drastically affect their health as well as cause environmental damage, all while violating the rights of consumers and farmers.
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.
With our growing population scientists are trying to develop more and more ways to help sustain our food production. 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 is 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 face upon it,it is a waste of time and resources fighting it.
...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.

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.
By the time naturalists learned of DDT's effect on wildlife, it was almost too late.
The growing demand for enhanced food productivity to meet the needs of the global population has led to use sophisticated agriculture technology in which pesticides play a crucial role. Pesticides are extensively used to increase agricultural products by preventing, controlling, or lessening the damage caused by a pest (John et al., 2001). Pesticides have been widely used througout the world since the middle of the last century. They are mainly used in agriculture and animal production, both including substances with high toxic effects and persistance in the environment (Beyer and Biziuk, 2008).
