Silent Spring - How Rachel Carson Changed the World
On September 27, 1962 Rachel Carson released her sixth book, Silent Spring. On publication day, the advance sales of Silent Spring totaled 40,000 copies and another 150 copies were sent to the Book of the Month Club (Frontline: Fooling With Nature, 1998). Silent Spring remained on the bestseller list for almost a year. The world was beginning to take notice. Countless experts and organizations have proclaimed Rachel Carsonâs book the starting point of the environmental movement. Carson described numerous case studies where the use of hazardous pesticides, insecticides, and other chemicals led to environmental problems all over the world. Whether directly or indirectly, everything in the environment is connected and affected by each other. Silent Spring describes, in depth, the harmful effects that chemical control has placed on all components of the environment. They include: air, water, land, wildlife, plant life, and humans. I will discuss each of these categories as examined in Silent Spring along with my personal analysis.
First I will discuss the damage from chemicals released in the air. Aerial spraying of pesticides, mostly DDT, began on a small scale over farms and forests. With the development of new insecticides and the availability of planes from the war, the sky almost literally turned into a shower of toxic chemicals. The justification behind the massive sprayings of the 1950âs was to exterminate exotic species like the fire ant, and the gypsy moth. The spraying was extremely careless, and resulted in heavily populated towns and cities repeatedly being sprayed with DDT (Carson, 1962).
Unfortunately, people and wildlife sprayed with DDT along with other chemicals had no warnings and no way to protect themselves. The government, without consent of those affected, risked the health of those exposed to the pesticides and the quality of the environment. Nearly everyone was exposed to the risks, in a direct or indirect way, from the extensive aerial spraying.
As described in the book, the gypsy moth is not a native of the United States. It had persisted in the U.S. for a great number of years without any need for extensive control measures. Carson states, ãYet drastic action was suddenly taken against them under the end-justifies-the-means philosophyä (Carson, 1962, p.156). Therefore, unnecessary health risks and damage to the environment were considered acceptable in order to eliminate the gypsy moth, which has repeatedly been unsuccessful. One reason the gypsy moth still thrives is because, like many insects, they have developed resistance to the chemicals targeted against them.
Humans are trying everything they can to trap the Gypsy moth and try to remove it from there eco-system, but the Gypsy moth keeps on reproducing. An annual trapping program is one method in which they place traps that attracts male Gypsy moths and gets them stuck in a sticky surface. If a substantial amount of moths are caught by the trap then more traps are set in that ecosystem. Bacillus thuringiensis var. kurstaki (BTK) is a toxic soil bacterium that is sprayed over an area to prevent defoliation. When Gypsy moths are exposed to BTK the toxic causes stomach poisoning and they would eventually die. (Government of Canada,
Like other law enforcement agencies throughout the United States, New Jersey has a policy that addresses police use of force. The New Jersey Attorney General’s Use of Force Policy was first put into operation in April 1985. The purpose of the policy is to serve as a guide for police officers who are confronted with use of force situations during their duty to preserve the law and protect others. This essay will provide a summary of the policies and practices of New Jersey’s Use of Force Policy. An evaluation of these components will be presented with emphasis on the legal sufficiency of the policies and procedures. Policy strengths and weaknesses will be identified in addition to suggestions for improvement. This essay will conclude with examples and the associated issues of less-than-lethal technologies (“Use of Force,” 2000).
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 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
This essay will aim to explore the controversial issue in regards to whether more police officers should be armed with Tasers. This essay will argue that more officers should not be equipped with Tasers, also known as “Conducted Energy Weapons” (CEWs), and that the issuing of Tasers by police services should be limited to supervisors and specialized tactical units until further research has been conducted on the effects that Tasers have on the human body. Furthermore the abuse of Tasers by police officers will also be argued as another reason why officers should not be armed with Tasers.
In 1962, the publication of Silent Spring Rachel Carson captivated the American public. Carson wrote about the harmful effects of chemical pesticides in the environment, and her writing was very reflective of the events occurring at the time. There is a strong connection between Carson’s writing and the Cold War. In fact, if it were not for the war, the American public may not have responded in the same way to Carson’s writing. Carson used tone and content as methods of getting her point across to the public. Silent Spring shined a light on the damage done to the environment as a result of the Cold War, and this issue was finally being recognized by American public.
In his short story, “Top of the Food Chain”, T.C. Boyle effectively argues that humans are destroying their planet with chemicals and that the general consensus of the public is that it is okay. He argues this efficaciously through the use of rhetorical and satirical devices, which are used throughout his story. Overall, I agree with Boyle’s argument that DDT is an especially harmful chemical to our planet, and while it may have had a place at one time, there is no need for it any longer.
The beanbag gun is an efficient less lethal weapon used by law enforcement because it can be used from a further distance when dealing with a violent suspect. Since September 2002 the beanbag gun has been used by the San Francisco Police Department 25 times to help subdue a suspect. According to Sgt. Rod Nakanishi it looks intimidating, so people just give up rather than be shot by a bean bag round. In the 25 incidents officers used the gun to resolve deadly encounters. The gun and ammunition seems safer for the officer and for the suspect due to the fact people do not die unless the officer aims in the wrong spot.
There has been a lot of controversy regarding the use of police departments using tasers. Many people think that tasers are less lethal and safer for police to use on everyone but, throughout this essay there will be many reasons as to why tasers are unsafe and pose a threat to someone on the receiving end. Tasers have been involved with many deaths and other injuries. The main topic that will be discussed in this essay is how sometimes shooting is a taser and just stunning the person is not all that happens. There are much more to stun guns than just 5 seconds of paralysis.
Just it isn’t a fake scene this is real life. There are six levels of force an officer can use and may have to use doing there time as an officer. The lowest level of force is presence of an officer at the scene and the officer’s body stance. This level of force is used typically whenever an officer first appears to a scene or a call. The second level of force is verbal control or commands. The verbal use of force is when an officer demands you to do something. The third level is physical control. This level involves escort holds, pain or pressure compliance. This force is brought in when a suspect tries to resist arrest or verbal commands. The fourth level is really close to the third, this is serious physical control. This really is when you use carotid control and electronic devices. The carotid control is a kind of choke hold which makes the person want to comply. The fifth level is impact and weapons. This is when you first so your willingness to use your baton by touching it or holding it out. Then possibly cause the suspect to feint so he or she can’t resist again. The last resort is deadly force. Most officer try their hardest to not have to get to this level or even be in a position to which this force is used. But deadly force is drawing your gun, pointing your gun, and, or finally firing your gun. (Police
As a result, “Nearly all agree that when an officer is facing a deadly threat, the proper response is to use deadly force”(Lind). Yes there are many people out there that can be a deadly threat to police officers because the way they are acting but, there are many innocent people that do not affect anyone and still have to be a part of the problem for no given reason. Although a police officer’s proper response is to use deadly force upon someone, there should be other alternatives or ways they can use before going into deadly force and possibly cause someone to lose their live. I certainly do understand that there are certain situations where a cop is coming across someone that is pointing a gun or knife at them and approaching towards them. So therefore them using deadly force would possibly be the right thing to do if they have too, but before using deadly force they should at least try deploying tasers or using bean bag guns to attempt in taking them
It is also used on those who may cause deadly harm to the officer(s) or others around the scene. This is one of the methods police use to control a person who has committed a crime or violation. The use of force is usually the last resort for police officers, however not always. Some police officers will encounter a situation where their life or others is immediately in danger and the use of force will be used then. The use of force includes empty-handed control, restraining a person, and deadly force. Deadly force is when a police officer cannot control the person with just physical force, so they have to resort to using their weapons on an
It’s in the news, its on social media, and its on cell phones. “Sexting” is just one way that many people engage in sexual activity. Sexting is sending and/or receiving sexually explicit photos through messages on their cell phone or through social media. Many Americans today, especially teenagers, are familiar with sexting, however, may not be familiar with the psychology behind sexting; why do we want to do it, what does it makes us feel, and what are the consequences of sexting. Anywhere from 20 to 30 percent of American teenagers actively engage in sexting today.
Reviewing Phillips, S., (2010), he states that the use of force should be restricted at all times and applied only as a last resort. The use of any force should be justified solely if all other measures of de-escalation have failed. Police officers must first explore the options of discussion, persuasion, mediation, and negotiations before turning to the use of force. In contrast, the exertion of force is sometimes inevitable, nevertheless the officers must take all precautions necessary when exercising their rights to ensure they do not impose any pain that can cause an inhumane treatment to a person. This is known as the continuum of force (Terrill, W., & Paoline, E., 2013). The continuum of force measures the idiosyncratic forms of force utilized by police officers. The lowest level, known as the minimal force, can be applied and labeled as handling a person too assertively. Whereas, the highest level of the continuum of force is called maximum force, that can be described simply as the use of lethal force; which includes the use of Conducted Energy Devices, also known as CEDs, such as Tasers,
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.
