DDT is an organochlorine insecticide and was used in WW II to take care of mosquitos that carry malaria. It was used on food crops and in buildings for pest control worldwide in U.S. It was a very effective at killing the insects that contain malaria and is very cheap to manufacture. Although there are some benefits to DDT, it is also very harmful to the environment.
The residue of DDT stays in the environment for such a long time that it causes problems in animal’s environments and humans. Studies show that when animals are exposed to DDT, they develop hyperexcitability, tremors, incoordination, and convulsions. Humans who are exposed to DDT, experience a strange prickling sensation of the mouth, nausea, dizziness, confusion, headache, lethargy, incoordination, vomiting, fatigue, and tremors.
In Borneo, they parachuted cats to take care of rodents while the spraying of DDT was in the air, this resulted to killing many cats because of the ingestion of DDT, which led to increased rodent populations. This story encouraged people to want to ban DDT. DDT was discovered in 1939 by

DDT breakdown products were found in 99% of people tested by CDC. Health impacts, such as in girls who were exposed to DDT before puberty are five times more likely to develop breast cancer in middle age according to the President’s Cancer Panel.
DDT can also cause pregnant women who are exposed to DDT to likely give birth prematurely or low birth rate babies.
Conclusion: DDT is highly effective at killing mosquitoes that carry malaria but the damage that it does is far too great causing the environment to suffer and people’s health and animals health to be affected greatly over time. I don’t believe that DDT is healthy nor should it ever be legal in the United
2.21 PESTICIDES Manahan (19..) discusses pesticides as water pollutants. DDT was introduced after World War II which accelerated pesticide use. Manahan (19..) states that by the mid-1990s agricultural use of pesticides was over 300 million kg per year and millions more kg of pesticides were used in non-agricultural applications. Manahan: Insecticides such as diazinon, carbaryl and chlorpyifos are most commonly found in water.
Most damages when exposed to teratogens occur during the embryonic period. Lead exposure during the embryonic period can cause stillbirths, increased risk for malformations, and VACTERL syndrome; VACTERL association is a disorder that affects
Mosquitos carry several diseases. Another statement the article made is “ The state and federal gov. has said the water treated with this chemical is safe.” But that is not true if you can still get asthma, eczema, and etc. The only difference is it takes longer.
In the 1950s and 1960s , something weird happened in the estuaries next to the long island sound , new York and Connecticut . Birds of prey , ( eagles ) fed on fish in the estuaries had soaring concentrations of the insect killer DDT in their bodies. Even though when the water in the estuaries was tested , it had low concentrations of DDT. In consequence , poisons that dissolve in fat (such as DDT) , can become more intense as they upgrade up in the a food chain in a process called biological magnification. When the pesticide mixes with the water , algae and bacteria are effected with the poison .
Developing fetuses are hypersensitive to the dioxins. Exposure to dioxins causes miscarriages, spina bifida, and other numerous health problems with the fetal development of the brain and nervous system. Dioxin was not intentionally added to the compound. It was merely a byproduct produced during the process of manufacturing, but the chemical companies that produced the Vietnam-era herbicides say they were not fully aware of how toxic the dioxin contaminant was so they accelerated the production. Dioxin was also found in varying concentrations in all the different herbicides used, but TCDD was only found in Agent Orange.
But, they are valuable when it comes to the relationship of human needs and desires. Example to this is explained with the example of penguins, where DDT was damaging penguins. Many crops were also sprayed with this pesticide so it was damaging animals and human’s nutrition and thus we were getting crops for cheaper. But after looking at this problem, DDT pesticide was being stopped and was replaced with another one.
The poisons such as DDT have the greatest affect on organisms at the top of food chains . for example , the white tailed eagle would have a greater concentration of DDT in its body than fish it feeds on . Top of the food chain large concentrations of DDT may kill organisms , decline its immune system , cause deformities , or damage its ability to reproduce . DDT can also weaken the shells of bird eggs. When eggs break too soon , bird embryos die .
“ A Black Snake will come from the North, Everything it touches it will slowly kill, It will poison every river.” - Sioux Prophecy. The Dakota Access Pipeline can create more jobs and will stop the United States from buying foreign oil. These are good value to push this forward but the list of Pros is short then the list of Cons.
Chemical warfare has been brought up multiple times throughout history. One of the most significant times chemical weapons have been used was during World War I. World War I introduced chemical weaponry to an extreme extent and for harsh purposes. There was a convention created called the Hague Convention which “discussed the issue of using chemicals as weapons” (First). The people within this group foresaw the potential use of chemicals during war, and wanted to try and prevent people being killed by this harsh weapon. There was later a second Hague Convention which added even more restraints to chemical weapons to further deter the use of chemical weapons.
Hydraulic Fracturing, otherwise known as fracking is the process of injecting large amounts of sand, water, and other chemicals into the shale rocks deep beneath the ground in order to flow natural gas back onto the surface of the well. This process was invented in the early 1900s, and has been controversial ever since. There are two sides to the debate, one being that fracking is known to be horrible for the environment. Fracking has caused families to need to be displaced, and emitted thousands of toxic chemicals into the air causing major public health issues. At the same time, fracking has reduced the reliability on coal, which is known to be horrible for the environment; it has also brought hundreds of thousands of gallons of natural gas
In the first chapter of “Living Downstream” by Sandra Steingraber discussed about personal experiences living in Illinois and discovering how much the landscape has changed over the years. In addition to the changing landscape, cancer, especially breast cancer, has increased in the prairies of Illinois and pesticides usage may cause. Much of the discussion first begin with the change of landscape as the prairies of Illinois has become a place for farming and pesticides. As farming became an important aspect of Illinois, pesticides were created to remove any bugs or insects from the product that is being farmed. A few pesticides formulas that came to be are atrazine, dichloro diphenyl trichloroethane (DDT), and polychlorinated biphenyls (PCBs).
Toxic chemical levels are enormous burdens to babies,and children
Wastes deposited by the animals can introduce nutrients and disease-causing organisms into the water, posing problems for aquatic organisms as well as human populations that use the water.” Another way that humans can negatively impact the water quality is by fertilizers and pesticides being put into the water. When this happens it can make the nitrogen and phosphorus levels increase which can be lethal to the organisms in
Birth Defects: Birth deformities from pesticide presentation is an alternate developing sympathy toward expecting moms, grown-ups and kids. The connection in the middle of pesticides and conception deformities has been fixed to utilization of family unit spreads that execute enclosure bugs, ants, mosquitoes and insects. These intense chemicals are utilized to assault the sensory system of creepy crawlies and slaughter them, however may represent a significantly more serious danger to your unborn child's wellbeing and expand the danger for oral clefts, neural tube imperfections, heart deformities and appendage imperfections. Introduction to pesticides and insect poisons ought to be evaded no matter what amid pregnancy.
In today’s world, there are many people creating new chemical substances that has negative effect to our world. Rachel Carson, in her article "The Obligation to Endure" argues that the pesticides and other chemicals we use are harmful to more than just the environment. I agree with Carson in her article, in that we should reduce most of the harmful chemical use and instead use technological inventions. Carson is a person who seems very passionate about the environment and is very concerned of its inhabitants. It is hard to believe that intelligent human beings would use bad chemicals substances that would affect the environment and themselves negatively.
