How Can DDT Affect Our Lives

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.

DDT is a very controversial product… but why? DDT was a pesticide used in the 1950s and it was very effective at killing mosquitoes. This was good because mosquitoes carry a very deadly disease called malaria. But soon the government banned its use in the USA. It supposedly has been decreasing the populations of bald eagles. They think that it makes the eggshells thinner, so when the eagle it trying to keep the eggs warm it might break the eggs on accident. Many people are happy about this ban and others are not. Some researchers feel that evidence supports a ban on DDT while others feel that it is an over reaction to an environmental concern. DDT has been shown to help control the malaria parasite. Evidence supports the banning

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.

In the book “Silent Spring”, the author Rachel Carson shows a detailed analysis of what happens when you rely too heavily on insecticides. In the beginning of the book, Carson explains how insecticides harm the natural processes in the environment. She talks about how water and soil is impacted. Then she talks about how massive insecticide spraying campaigns can inadvertently hurt other organisms such as birds, salmon, and humans. One of the scary things I learned was that back in the days, the government approved of spraying DDT from airplanes in hopes that it would control gypsy moth populations. It seems like they were trying to find a quick and easy solution that they did not consider the long-term consequences of their actions. She also

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

In the modern world, we have few similarities to our ancestors. However, there are a few aspects of our culture that have lasted through the centuries. One of the most prominent is our constant use of symbols and pictures to convey complicated messages. One of the reasons for this is the fact that pictures can touch our emotions in a way that few things can. This interaction with emotion is especially useful in arguments. The picture taken to protest fracking used this knowledge to strengthen their argument that fracking for oil is harmful because of contamination the process leaves behind.

In the early 1940’s, a new technology emerged that was able to successfully combat crop-damaging and disease-carrying insects. A new age of synthetic chemical pesticides use arose. After their impressive success in fighting deadly insect-borne diseases during World War II, pesticides were used widely to combat insect pests for agriculture and public health. Few people challenged the benefits of the new scientific and technological products and many embraced pesticide use with enthusiasm. Despite its success, doubts about pesticide use began to appear a decade later in the 1950’s, when the government began a vigorous pesticide campaign across the country against insect pests. Scientists began reporting heavy losses of avian and

Carson’s primary argument is that the ecosystem is unable to adjust and rebalance itself due to the rapidity of the introduction of chemicals into the environment. She points to the common knowledge that it took hundreds of millions of years for life to evolve to its current state. She goes on to explain how, given time (eons), the environment adjusted to natural dangers such as radiation emitted from certain rocks and short-wave radiation from the sun, but that it is impossible for the earth to adjust and rebalance in the face of man-made threats in the relative miniscule timeframe of decades. Her appeal is both logical and emotional. Logically, chemicals sprayed on croplands, forests or gardens will kill not just “pests” but other living organisms, and that some amount of these chemicals will end up in ground water, causing problems for anyone or anything that depends on this water. Emotionally if the possibility of permanent gene damage, which cause deformities, cancers, and early death, is not enough to encourage a second look at this issue then there is no hope for the planet’s future.

McGinn argues DDT is no longer as effective, it harms the environment, and therefore we should focus on the alternative solutions. She explains the ecological damage caused by DDT because the pesticide bioaccumulates. This means the DDT is absorbed by predators when they digest an exposed prey, and the concentration increases as it gets higher in the food chain. These long-term exposes are then likely to lead to physiological abnormalities, which somehow negatively affect both ecological and human health (McGinn, 285). In addition to the toxicity, the pesticide has lead to a resistance. Malaria developed resistant strands and is not likely to disappear even if the use of DDT is halted for years. She explains if this toxin is reapplied

In fact, Carson outlines her evidence and claims for the global environment and the whole of humanity. In addition to this, it is worthy to mention that, Carson was directing her message to policymakers because they had the power to ban the manufacture of the pesticides and insecticides. Furthermore, Carson’s messages were directed at certain companies and the manufacturers of pesticides such as DDT. The catalyst of this message stemmed from the widespread use of insecticides both at home and in offices. As it seemed, there was a widespread rate of ignorance and misinformation across the public on the harmful effects of these pesticides.

Nonetheless, this impact is far less lethal than Roundup. 5 deaths in the Roundup & 1 death in the control group.The larvae were exposed to an oral, dermal, and inhalation of the herbicides. The larvae was exposed three ways only being in one environment. By living in the 200 ml containers the larvae had the opportunity to ingest, breathe in, and had it in its skin to make sure the herbicide was fully in their systems. The snout to vent length there was no significant differences in Control and Agridex, and Control and Roundup. The limb development there was no significant differences between control and agridex. The asymmetry was growing significant more than agridex (p < 0.05).There was no significant between control and

At the same time as DDT was being used to eliminate malaria, farmers were using the chemical in substantial amounts as an insecticide. Monoculture farming was introduced in the 1950’s and DDT was used by farmers to spray the large stretches of land their crops covered. However, environmentalists and scientists soon were observing that DDT was harming the ecosystems around which it was being used. DDT is considered harmful because of its chemical properties (DDT (dichlorodiphenyltrichloroethane)). It was thought that consumption of DDT large quantities could be toxic. DDT is also dangerous because it has a long half life which means it takes a very long time to break down in the environment. DDT 's long life is due to its low solubility in

DDT is a good insecticide for a couple different reasons. One being that it is fairly inexpensive to make. This was extremely convenient in times of war. Compared to other insecticides, pest services, and bug controls, DDT can be 2-20 times less expensive. Another positive note for using DDT is the insecticide is only slightly toxic to humans. To kill the bugs, the insecticide is absorbed through the outer layer of the bugs skin, also known as its exoskeleton. Once inside the bugs flesh, it attacks their nervous

Insecticides, herbicides, fungicides, rodenticides, and antimicrobials are all pesticides. Many insecticides are designed to attack the brain and nervous system of an insect, which means they can also have a neurotoxic effect on humans. They are generally the most immediately toxic to insects. Farmers get caught in the “pesticide trap” as they are forced to use more and more pesticides to control insects and weeds that have formed a resistance -- also referred to as “superbugs” and “superweeds.” Each year pesticide resistance is increasing. “Between 500 and 1000 insect and weed species have developed pesticide resistance since 1945. Each year an estimate of 1 billion pounds of pesticides are applied throughout the U.S. and over 17,000 are on the market. People using pesticides and others in the community who live near are most at risk for pesticide poisoning, but studies by the Centers for Disease Control show that all of us carry pesticides in our bodies.
