The Environment And Environmental Pollution

To understand pesticides, we must look at the facts about them. According to the EPA, pesticides are chemicals specifically designed and sold to prevent, destroy, or repel pests from garden, greenhouses, fields, and orchards (Learn About Chemicals Around Your House). Charlotte Gerber’s article, How Do Pesticides Kill Bugs, explained that pesticides targets insects and kills them by attacking the nervous system and then when the muscles are over-stimulated, this will lead to paralysis and death. The effect of the organophosphates that cause that in pesticides was discovered in the 1930's during World War II. They were used in the creation of nerve gas, which was used in chemical warfare. When used in lethal dosages for humans, organophosphates cause extreme excitability, convulsions, paralysis and in most cases, death (Gerber). According to Effects of Pesticides on Human Health, The World Health Organization estimates that there are 3 million cases of pesticide poisoning each year and up to 220,000 deaths, primarily in developing countries (Lah and Glibert 2011). Children, and any other young and developing organisms, are particularly vulnerable to the harmful effects of pesticides. Even very low levels of exposure during development may have adverse health effects. Exposure can even lead to neurological health effects such as memory loss, loss of

This book was written in an era when pesticides were used with relative abandon: sprayed over entire fields of crops, and anything nearby. Something had to be done, she believed, especially since pesticides that were used decades before could still be found in the human body and in the environment.

In the book, Silent Spring by Rachel Carson warns people about the use of insecticide. When people use pesticide to kill insects it leads to problems because it would transfer from people to animals. Carson shows us when the earth is contaminated with pollution, it is going to take generation after generation to fix. When the chemicals were discovered to make pesticides it was founded by an accident. People started to use pesticides to kill insects, but the pesticide started to make people and animals to get sick or die. The pesticide would enter the body animals or people and it would transfer to the offspring of the animals or human beings. According to Carson pesticide would go to the water supply where people drink from and get sick or die. Carson suggests that we should not stop using pesticide, but to limit our usage of pesticide. I agree with Carson that we should limit the use of pesticides. People around the world she cut back on the usage of pesticides because it hurts the health of human beings, animals, and water supply.

In Silent Spring, Rachel Carson describes how dangers pesticides and insecticides are. She mentions that the large number of chemicals keep increasing each year which make it unsuitable to every organisms’s life such as human, animals and plants. She also mentions that insecticides kills or make everything bad. For example, it kills fish and make human nervous system bad. She said the government has lack understanding and negative impact of using toxic chemical. After she said this, she also mentions that eat these bad chemicals will bring serious health problem.

Direct human poisoning is only a part of the danger of pesticide use. The toxic effects of pesticides are felt throughout the environment as well. Improperly used or disposed of pesticides that enter the waterways through runoff can cause substantial fish kills . Wild animals, domestic livestock, and birds also consume pesticides by eating smaller animals or vegetation in which toxic chemicals persist. The poison moves up the food chain in this manner and is often eventually ingested by humans .

Pesticides are commonly used in agricultural production to prevent or control pests, diseases, and other plant pathogens maintain a high product quality. Even though, pesticides guideline is firm, to function with reasonable certainty and minimize the impact on human health and the environment, serious concerns have been raised about health risks resulting from pesticide exposure consume in food and drinking water, and inhale in the air. Therefore, the pesticide exposure disrupts the transmission of the nerve impulses, by reducing the ability of the enzyme cholinesterase to regulate the neurotransmitter acetylcholine.

Many pesticides became much more common after the Second World War, in which, due to various research projects identified controlling disease transmission to soldiers as a possible side benefit of chemicals developed for warfare. Development of many pesticides did occur before World War II, but it was only after their use in the war that they became more commonplace (Finnegan 1989). As crop yields increased and disease from insect vectors became less common due to the use of available pesticides, farmers and politicians began to push for increased usage of pesticides, tripling their manufacture

Pesticides are substances utilized for killing bugs or different creatures unsafe to developed plants or to creatures. Pesticides are permitted onto the market before their effects are completely comprehended. The science of pesticides is progressively certain that even low levels of pesticidal toxicity in a human can still hurt a human 's health, and children are especially defenseless.

Industrial development of the past 200 years has brought immeasurable wealth and prosperity. However, it has also caused unintended eco- logical degradation and pollution (Shrivastava, 1995). Pollution is defined as “the introduction of contaminants into the natural environment that causes adverse changes (Khamis, 2017). Pollution is a worldwide problem that affects humans on a day-day basis causing disastrous and deleterious effects that eventually lead to loss of life. Pollution can be of various types; it can be in form of chemical energy, light, heat, noise. These are referred to as pollutants and most are as a result of human activities. The drastic effect of these activities greatly endangers life and has a lasting impact on the sustainability of the environment. This is why the issue of pollution is of utmost importance to every individual as it will affect the quality of life of the human race if its rapid progression is not curtailed.

The use of pesticides have been dated back to over 4,500 years ago, when the Sumerians used sulphur compounds to protect crops from mites and insects (1). The use of pesticides are abundant in the United States and globally. The United States accounted for over one billion pounds of pesticide use in both 2000 and 2001, with over five billions pounds used worldwide in each year (2). The United States accounted for approximately 23% of the global use of pesticides. Pesticides have long been used and will continue to be used. There are strict regulations that govern the creation, reformulation, sell, and use of pesticides. Even with these strict standards, there have been pesticides authorized on used that cause adverse effects to health and/or the environment. These adverse effects have been discovered through varies methods such as toxicological profiles, exposures assessments, epidemiological studies, etc.

In 2014, California is the state that produced the most agriculture products across the nation. In addition, around 200 million pounds of pesticide ingredients were used in the field (Shelton, Geraghty, Tancredi, Delwiche, Rebecca, Ritz, Hansen, Hertz-Picciotto, 2014). Pesticides are used on the agriculture products to prevent damages from insects, and it is vital for the high quantity production of today’s world. However, pesticides are also a toxic chemical for human. There are innumerous types of pesticide can be used in the field. Some of them are banned because of its adverse effect such as dichlorodiphenyltrichloroethane (DDT). Because of the huge consumption of pesticides, the safety of the pesticides is a major concern for public. Studies had shown that pesticides exposures are related to many health issues. It is possibly affected people’s brain, respiratory system and growth, etc. (Shelton et al., 2014). Therefore, the concerns about pesticide exposures are necessary. Other than the general public, there is a group of people that people should not forgot— farmers. They usually work in the farm for a long period of time. Therefore, they have a high risk of exposures to pesticides. A long-term exposure of pesticides is possibly caused serious health issues. Therefore, they are the people that suffered the most from this issue. This paper will demonstrate the health issues on farmers that associated with pesticides exposures. In addition, both short term and long term

In 1775, Sir Richard Arkwright began his revolutionary work in the modern industrial factory system. Arkwrights innovative work on an improved spinning machine to create stronger yarn, jump started his career as an entrepreneur. His assets rose as he developed the first horse driven spinning mill; a factory in which he developed a system to divide labor and maximize profits. However, Arkwright's ingenious method evolved into something he would have never expected. His methods decreased living standards due to the increase in low wage jobs, along with the depletion of natural resources, and heightened the use of harmful chemicals; resulting in increased pollution. And “the Industrial Revolution of the mid-19th century introduced new sources

Vehicles emissions and waste products currently have a significant impact on the health of the environment. In American vehicles have the largest impact upon air quality, producing approximately one-third of all America's air pollution (National Geographic, n.d). There are multiple waste products which are produced by vehicles including; smog, carbon monoxide, and other toxins which are emitted out of the tailpipe (National Geographic, n.d). Tailpipes as they are at street level, are extremely dangerous as humans are able to breathe in the polluted air directly into their lungs (National Geographic, n.d).

The paper will talk about research conducted about the environment and ways to prevent pollution. Some of the examples talk about the situation will be trash pollution, water pollution, and CO2 emissions. In the following discussion by these authors talking about carbon dioxide emissions. (EHLERT, ZICKFELD, EBY, GILLETT) (2017) Along the years the best option is for people to prevent the rising temperatures around the globe. Also, the paper will discuss research related to pollution in the environment and rising temperatures. A relationship between people and environment will be described to the key to success for society. The articles about water pollution talk by (Barghouti, Marie) (2016) will provide several examples of what must be done to the environment and water pollution. In the start will talk several alternatives to a contamination free environment. Then the best chance can be to start small in the community and soon move from there. Best examples are found in the article (Trash Causes More Pollution) will discuss the effects of increasing amount of plastic in the environment and how people are contributing to more pollution best shown by the irregular distribution of trash around the globe.

For my final project I have chosen to research water quality, primarily focusing my attention to watersheds on invasive and non-invasive species that can potentially wreak havoc on bodies of water. There are a total of 944 lakes located here in NH where I live. The largest lake in the state is Lake Winnipesaukee, which is very popular for many reasons, including its beauty and all the recreational activities it brings. While most spend their days swimming and boating on the “big lake” (that’s what we locals refer to is as), they are seemingly unaware to the dangers that lurk beneath the surface threatening economic and ecological losses. The biggest threat to the big lake is milfoil. Milfoil is an invasive aquatic plant that has been contaminating Lake Winnipesaukee since it was first spotted in 1965. This topic has always been of concern to me. It’s sad, really. Something so beautiful and natural can be overrun, affecting the livelihood of the lake and all who enjoy it. My hope is that through education we can greatly reduce the amount of milfoil in our lakes.
