Introduction to pesticides : Pesticides are designed to kill something. In agriculture, pesticides are use to kill the organisms or compounds that feed in crops. For example, preventing the spread of bacterial, the growth of mould, to control mice and rats, and also kill the organisms that is not beneficial for the plant. Pesticides is very convenience to famers because it protect the crops and increase the harvests. But over using the pesticides will cause pollution to the enviromrnt and also the ecosystem. In our lives, pesticides also make us easier. For example, the use of pesticides in wood makes will makes our furniture last longer. And also our clothes, the pesticides are also been using in the wool to make our clothes as longer shelf life. Types of pesticides : 1. Algaecides is use to execute or demostarting the development of growth of algae. 2. Antimicrobials and Disinfectants is use to control germs and microbes such as bacterial and viruses. 3. Fungicides is to control contagious issues like moulds, mildew and rust. 4. Herbicides is use to kill or inhibit the groeth of u...
There are many issues regarding the raising and producing of various livestock animals, and the use of pesticides on various types of crops. The movie Food.Inc does a good job explaining these issues, but in a very biased way. It makes agriculturists look like terrible people, when this is not the case.
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.
Have you ever thought about how your fruits and vegetables are grown? How about which ingredients are put into bug sprays and insecticides to ward off those pesky insects? Look no further because author Rachel Carson looks deep into the many environmental issues caused by pesticides and herbicides in her New York Times best-selling novel, “Silent Spring.” “Silent Spring” is a collection of studies which were performed in an effort to educate others about the harmful things occurring everyday to their foods and every-day environment in hopes of giving them a wake up call. This novel is thought by many to be a revolutionary novel that forced people to take notice of the harm being caused in their world, many of which people were unaware of. After discovering the results of these chemicals, it really makes one wonder, is the luxury of being insect free really worth all of the consequences?
Three substances mainly make fertilisers: nitrogen, phosphorous and potassium. Their percentage in the solution will change the effectiveness on a determinate plant; for example is recommended to use high proportion of nitrogen fertilizers during the spring growth of spurts. The fertilisers can be spitted in two categories: organic that contains a low level of nitrogen, phosphorous and potassium and aren’t toxic to the environment and synthetic that are made by a high concentration of the three substances and can be corrosive to the environment if are overused.
“Antibiotics" is the name given to the group of chemicals, particularly in medicine, that stop or inhibit the growth of, microorganisms such as fungi, bacteria, and parasites, or that kill the microorganism. They are, however, completely ineffective against viruses. There are two kinds of antibiotics, namely; bactericides, which interfere with the cell wall or contents of the bacteria, thereby killing it, and bacteriostatics, which prevent the bacteria from reproducing. They are used to treat bacterial infections in humans and animals. Bacteria are microorganisms consisting of single cells, and reproduce by mitosis. They usually live in colonies. Some bacteria and other microorganisms produce antibiotics to kill off other species, making more resources available for the organism making the chemicals. Ironically, it was this that led to the discovery of antibiotics in 1928, when Alexander Fleming noticed that the fungus Penicillium notatum, which had contaminated a sample of pathogenic bacteria, had killed the bacterial colonies in a petri dish.
Antibiotics have been critical in fighting bacteria-caused diseases for the past 60 years. Bacteria in the human body are able to reproduce at a rapid rate and this is a huge problem when the bacteria are disease-causing. Antibiotics are drugs that are able to stop bacterial growth, and kill off bacteria in living organisms.
Antibiotics are powerful substances which are capable of inhibiting bacterial growth. Antibiotics can be consumed from any part of the body. Essentially there are two different types of antibiotics which perform different operations to the body. (Medical News, 1) The first discovered type is bactericidal, which not only inhibits but initially eliminates the bacterial or microbial organisms, this is done through exterminating the bacterium cell wall which furthermore erupts and causes the bacteria to be killed. The second type is bacteriostatic, as the name states. It aids to inhibit and limit bacterial growth. The antibiotic stops bacterial growth through stopping the process of protein synthesis, or bacterial reproduction. It is consumed to stop the growth of a microorganism permanently or temporarily. (Scientific American, 3) Patients consume antibiotics through the mouth. Antibiotics can also be directly injected into the body. Others can be applied on the infected area of the body, and physically cured or eliminated. (Medical News, 1)
A question commonly associated with the word insecticides is, what are they? Well I have the answer, insecticides are chemicals that are used to eliminate insects. In the agricultural industry, insecticides are classified into different categories,and the most used is carcinogenic. A carcinogenic insecticide is a substance or agent producing or causing cancer. This is just one of the reason that I believe there are more cons then pros when dealing with a insecticide.. When I was a kid , I can remember my parents taking me and my brother an apple orchard and picking apples. I couldn't wait to eat them until I got home, but we couldn't eat an apple because of what insecticides could be on the apple
ANTIBIOTICS :- Antibiotics are medicines that fight bacteria. Antibiotics can save lives, if used properly. Antibiotics either kill bacteria or keep them from multiplying. Antibiotics do not fight virus infections. For example: Cold Flu ANTIBIOTICS: Most coughs Sore throats (Exception: strep throats).
...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.
As time has progressed, there has always been an overarching need for high amounts of crop production throughout the world. With the rapid rate of population growth, the need for crops and other sources of nutrients is only increasing. In order to meet these high demands and increase yields, farmers and other agriculturalists have started implementing the use of pesticides. These chemical mixtures are being used in order to prevent, destroy, repel or mitigate any pests from destroying growing crops. However, using pesticides on crops can create massive amounts of pollution, negatively affect an individual’s health, and can spark biodiversity loss within an ecosystem. According to Michael C.R. Alavanja, “Over 1 billion pounds of pesticides are used within the United States (US) each year and approximately 5.6 billion pounds are used worldwide”. With all this in mind, it is clear that pesticides should not be made available to farmers and agriculturalists, and should
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.
Organic farming has mushroomed drastically in importance and influence worldwide from its modest beginnings in the first half of the last century. Organic farming is production of food and livestock without the use of herbicides, pesticides, weedicides, fertilizers or genetically modified organism and use natural resources such as manure and compost instead. In other words, it is a production system which maintains the quality of soil ecosystem as well as human beings. According to IOWA State University, “the chemicals were not used for farming before World War 2. A number of munitions used in farming have contributed to field of agriculture. For instance, ammonium nitrate used as ammonium nitrate fertilizer”.
The pesticide is a controversial topic since farmers are used it to gain their yield. Especially, pesticide is discovered during World War II as a chemical weapon that mixture of multiple chemicals together to kill human. Therefore, Chantries redesign pesticide to kill an organism where and when we don’t want it. Because people want to go to the grocery store to buy the perfect product, pesticide makes it happens and with a little cost for farmers. Nonetheless, pesticide also is the expenditure of life expectancy, which directly threatens people and poses risk of mortality rate. Abusing the pesticide has multiple affects on our society, (Add).

The use of chemicals in weapons dates back thousands of years, from poison arrows to poisonous fumes. However chemical warfare took a new approach during World War I. The first large scale attack was chlorine in april 1915. World War II brought on a entire new spectrum of chemical weapons and many countries obtained large stockpiles.1There are four different categories in which chemical weapons are organized based on what the effects are. The first category is blister agents which cause blistering of the skin. The second category is choking agents which cause the airway passages in the victim's throat to close resulting in death. The third category is nerve agents which causes damages to the victims nerves. The most recent uses of chemical weapons was on august 21, 2013 in Damascus ,Syria which resulted in numerous casualties.2
