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 …show more content…
In a study conducted by the University of London’s Centre for Toxicology, 30 out of 37 commonly used pesticides have been tested to block or mimic male hormones (Cone). This blockage can affect testosterone levels negatively as well as other androgens produced within a male’s body causing serious health concerns with fertilization, hair loss, and low sex drive. The study also discovered that certain pesticides that are used within today’s agriculture can, “…activate or inhibit hormone receptors in cells that turn genes on and off” (Cone). Therefore, fetuses and infants can be at high risk when exposed in the womb or through breast milk since the hormones being turned on or off control masculinization of the reproductive tract. Overall, pesticides seem like they are doing more harm to human’s health then they are at keeping crops healthy and should be eliminated from modern agriculture
Between 1961 and 1971, Monsanto, along with Dow Chemical and other chemical companies, provided herbicides and defoliants, including Agent Orange, to the U.S. military during the Vietnam War. As a consequence of the exposure to dioxins contained in the defoliant, the military personnel in Vietnam suffered of injuries, such as Chloracne, heart disease, prostate cancer, respiratory cancers, etc. (“Veterans' Diseases Associated with Agent Orange”) In 1980, a class-action lawsuit concerning Agent Orange was filed against Monsanto, Dow Chemical and other chemical companies, but these companies denied that Agent Orange was linked to the veterans’ medical problems. In 1984, seven of the chemical companies involved decided to settle the class-action
Do you know what you're really voting for? Iowan farmer Reg Clause suggests you may not in his column, “Say ‘no’ to GMO labeling.” Reminding readers that general election day has come, he attempts to convince us that a certain law should be voted against. The proposed legislation would mandate all foods that contain genetically modified organisms, also know as GMOs, to display a warning label on their packaging. He argues that this would be detrimental to the good name of these types of foods when they do not deserve to be shamed. I agree that the genetically engineered crops should not be labeled, but not because that would tarnish their name. However, the reasoning for my opinion comes from the perspective that it would not only be impractical
Chemical pollution into the environment can cause both genotypic and phenotypic changes in many organisms, including humans. More specifically, environmental pollutants like BPA can act as xenoestrogens (estrogen imitators), ultimately affecting hormonal activity and production in an organism. This alteration in activity and production can be termed as endocrine disruption. The endocrine system regulates a variety of processes responsible for growth and development, including gonadal formation and function, digestion, metabolism, sex differentiation, and embryonic development (reviewed by Flint et al., 2012). Chemicals that interfere with the function or structure of the endocrine system can be defined as endocrine disrupting compounds (EDCs) (US Environmental Protection Agency, 2007).
Pesticides that behave like the female hormone estrogens can have serious effects on reproductive success and function on animal exposed to them. Reproductive success or fitness is defined by having live reproductively capable off...
...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.
The term GM foods or GMO (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques (Whitman, 2000). These plants have been modified in the laboratory to offer desired traits such as increased resistance to herbicides or improved nutritional content. Also, genetic engineering techniques have been applied to create plants with the exact desired trait very rapidly and accurately. For example, this is done by the geneticist isolating the gene responsible for drought tolerance and inserts it into another plant. The new genetically-modified plant will now have gained drought tolerance as well.
Over the years, meat eating has grown dramatically in many countries. Demand for meat production increased at a fearsome speed, which led to producers using pesticides and fertilizers on their crop. Because of our exponential population we could not begin to feed the population of the world without them. Farmers will need to increase the amount the chemicals used on their crops and animals to accelerate production process i...
Nature practices diversity and for good reason. In nature and organic farming, if there is a threat to one species, there are others to balance the decrease in the threatened species. Conventional farmers and the modern food industry argue that planting the same crop year after year is convenient and profitable because it cuts down on the different types of farm equipment necessary in production, and initially, on the types of pesticides, herbicides, and fertilizers needed. However, in this unnatural environment, tremendous amounts of pesticides and fertilizers are needed to support crops as increased resistance occurs year after year (Pollan 72).... ...
To help keep crops from being destroyed, conventional farmers use many methods such as pesticides, herbicides, and fungicides. Nearly 1 billion pounds of these chemicals are used every year (“pesticides”). Because of this excessive use, some scientists express concern that using artificial chemicals in the farming process could produce unhealthy crops. People who ate it over a long period of time could suffer from degraded health and stunted growth (“Organic Foods”). For example, in 1989, the EPA banned the use of Alar which was a chemical used to ripen apples (“Farming, Organics”). This chemical proved to be carcinogenic after causing tumors in mice after several laboratory tests (“Organic Food”). As a result of these findings there was a dramatic increase of the sales for organic food (“Organic Food”). Another study found that Atrazine (one of the most widely used herbicides in the United States) has the potential of being carcinogenic and reducing sperm counts in males (“Organic Food”). This was further proven when evidence was found that chemicals u...
Dietary supplements can be a good thing to use but they aren't always what they say they are. They are used by over half of all Americans and those people normally take a multivitamin or protein supplements after their workouts. In fact, whey protein is the most supplied dietary supplements among all Americans. People would also say that supplements are helpful when they become older in age, but then those people who believe supplements do not work at all. What they don't know is that if individuals take too much or too many supplements, it could hurt them and not benefit these people.
The term “organic” is almost everywhere in modern society, whether it’s used to promote a product or it’s debated on whether it really benefits the human diet. Organic food is heavily debated on as it appears more and more in local grocery stores and farmers markets begin to populate, it raises questions such as “Is organic food better than food grown with pesticides and biologically engineered genes?” and “Are there benefits to eating organically over foods grown in any other way?” In terms of what data and results show in research may help lead to answers to most of the heavily debated issues throughout discussions on organic food.
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.
Processed foods are in everybody’s lives, but are they safe? Processed foods are foods that are in boxes, cans, or bags usually containing artificial colors, flavors, and other chemical ingredients that most people can’t pronounce or recognize (SFGate). Processed Foods may taste good but can have terrible side effects. Most people don’t see the harmful effects of processed foods. Processed foods should not be eaten.
Today people are concerned with what they eat in order to lose or maintain their weight. What people do not know is how their food is obtained, how veganism is beneficial to their health and what the food industry thinks of vegans. Veganism is the avoidance of any animal products particularly food. Veganism confronts the issues of animal welfare as well as dietary concerns for humans. It is an effective method to live a healthy and humane lifestyle.
Pesticide is a chemical used to prevent, wipe out and control the pest problem in agriculture. The use of pesticides have become a common practice around the world, and used almost everywhere, such as agricultural fields, homes, park and school, and so on. Most pesticides are insecticides, herbicides and fungicides that have distinct purposes. Insecticides are used to control insects; herbicides are used to destroy plants; fungicides are used to prevent molds and mildews. Most commonly pesticides contain highly toxic chemical such as Acid copper chromate (ACC), Acephate and Chlorpyrifos, and so on. One of example of insecticides, Chlorpyrifos, sprays widely on a variety of food and golf courses in order to control pests in a cornfield. However, “Chlorpyrifos can cause cholinesterase inhibition in humans; that is, it can over stimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.” (EPA GOV) In the market has thousands of products are similar as Chlorpyrifos.
