When pondering on the fears associated with foods normally digested today, one may invoke up depictions of diet borne disease or famished families in a distant Third World nation. Although conditions such as these are unfortunate, individuals in industrialized countries frequently inquire where their meal originated from and what it entails, but seldom go beyond that thought. Many forget a crucial element that goes in the preparation of produce they just bought, and that is pesticides. Pesticides are chemical compounds typically sprayed on crops to help eliminate bugs by containing an unwanted taste or creating a disease within the bug. However insects have learned to adapt to the chemicals, only strengthening the pest’s resiliency. Pesticides
Topsoil, air, sunrays, and water are perfect illustrations of the negative effects. Pesticides predictably mark numerous adjacent plants and animals causing damage and demise. The spray’s fatal effects fluctuate from one organism to the next. For instance, because pesticides leaks into water channels, heaps of fish perish annually. Likewise, pesticides fuel air pollution, and even harm the ozone layer once they become air borne after application onto the upcoming crops. According to the EPA, a crops capability to sprout and arise is similarly afflicted by pesticides. As the pesticide is absorbed within the soil, it depletes necessary elements like nitrogen and phosphorus found in fertile soil causing a weakened route systems. Not only does this weaken the plant, but it also causes great distress in nutrient value the crop should produce. Furthermore, within the article "Harmful Pesticides Found in Everyday Food Products" Lu proposes due to the survival of the fittest, pest resilience will escalate until pesticides no longer become an efficient method of protection. Therefore, pesticide’s initial effort to generate improved crops essentially yields a further toxic and chemical rich
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.
The book starts with a foreword that highlights the motivation for having written the book. The book has a table of contents organized into seventeen chapters that highlight the different effect of the use of pesticides to the ecological system within the earth surface. The book is chronologically organized into chapters that flow and express a single idea for the writer. This organization has given the book much readability regarding the flow in its content and format to a
“(Silent Spring) spells out in memorable detail through out the book the effects of synthetic insecticides and herbicides on water, soil, plants, wildlife, fish and human beings. But in the book’s final chapter she suggests alternative courses of action for mankind —- a way out of this march toward death.” (Holmes, Pg. 123)
Actually it is said that insects are becoming immune to these poisons. When a insecticide is first used, a small group of the insects may survive the exposure to the insecticides due to their distinct genetics. These individuals pass along the genes for resistance to the next generation. The over and over uses of the insecticide will actually increase the proportion of less-effected insects in the population. Worldwide, more than hundreds species of insects have developed some degree of immunity. There are many important issues in the world regarding insecticides deterioration of the environment and it's affects on the average person. Though, the one that is worst then you know it is that individuals have it in the food that they consume. Yet it is still found daily in foods all around the world. Insecticides are used by produce growers to control insects and some pests that can destroy crops. These toxins are back firing on its users because they are being eaten by humans in the forms of fruits and vegetables that have remaining of the insecticide on them. How safe are these toxins to humans and what is being done help the environment and the health of humans and non-targeted animals? How much does the average person consume harmful amounts of toxins during every meal? If the levels are unsafe, why is this problem continuing to be ignored by the people who are supposed to
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...
Civilization began with agriculture, and agriculture continues to be an integral part of our lives. Civilization brought knowledge, knowledge brought technology, and technology brought chemicals and pesticides to “improve” our world. “The Obligation to Endure” is an excerpt from Rachel Carson’s “Silent Spring,” a passionate and masterful work on the results of civilization’s efforts to control pests and insects. These effects include destruction of the environment, alteration of gene structures in plants and animals, water contamination, and an upset of nature’s delicate balance. This article is an impassioned plea to the world to understand the threat and demand the information necessary to make an informed consent on use of these deadly substances.
With the world having so many people on it we use a lot of pesticides and fertilizers. If it was not for the help of these we would not have gotten to the place we are now. Pesticides and fertilizers do a lot more than just help grow and safe from pests. “Nearly 50% of the world labor is employed in agriculture and they significant risk”
For instance, in Seeds of Death, Monsanto spread roundup, a pesticide, on their crops and realized a roundup resistance bacteria continued to grow. In response to this, Monsanto collected the bacteria and took a piece of its DNA to create roundup resistant crops. Although this seems like a good idea, it makes crops weaker and makes it easier for crops to be wiped out by a stronger disease. In addition to this, the pesticides also pull nutrients from the soil, therefore resulting in the microorganisms in the soil being killed. This, in turn, leads to the soil being filled with poison and also being infertile in the near future. The worst part about these pesticides is that once it enters the environment, it’s in the environment
Conventional farming practices are responsible for many negative health and environmental issues. One of the main issues is the creation of monocultures in the farming environment. Specifically growing the same species of plants or animals in mass quantities without variation every season is not natural. Monocultures do not exist in nature (Pollan 67). 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, in the types of pesticides, herbicides, and fertilizers needed. However, in this unnatural environment, tremendous amounts of pest...
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.
With the world’s population exponentially increasing, massive hunger in third world countries, and an ever-changing environment due to climate change, conventional crops can no longer sustain the world’s population. The solution to this conundrum lies in the introduction of genetically modified crops: a new breakthrough in the agricultural industry. GMOs (Genetically modified organisms) have resistance to new aggressive sources of weeds, pests, and other diseases to thrive in harsh environments. They also have larger crop yields, crucial to feeding a growing population. Moreover, some even assert that they contain more nutritional value and taste better than traditional crops. Despite all of this, perhaps the most crucial benefit of GMOs is the fact that they can be resistant to the effects of climate change. Increasingly frequent droughts, storms, and bouts of heat have plagued farmers and decreased crop yields significantly. Global warming is inevitable and could cause a decrease in the food supply when the world desperately needs an increase. In the intense debate over GMOs, the question now is not whether or not we should use GMOs, but it is how we should use them. There are many possible safety hazards in GMO products and the safety precautions that are currently in effect are not enough to regulate the numerous threats that GMOs could propose. There may be a tradeoff for the numerous benefits that GMOs grant to the food and farming industries. A documentary brings up a very chilling question: if pest insects die after consuming genetically modified foods, what will happen to humans who consume the food? These fears are merely the tip of the iceberg in a sea of uncertainty. Many professors fro...
Pesticides are contaminating the Earth’s water supplies. There are seventeen pesticides found in twenty-three state’s water supplies right now. Scientists at Cornell University conclude that 99% of pesticides miss the intended source and find their way into the water, air and soil. Most of the pollution isn’t strong enough to create an immediate impact on humans so the wildlife is the primary target to these contaminates. Animals such as the European Starling birds are constantly being tested and found that they are greatly affected both behaviorally and psychologically.
The new chemicals which are produced to kill these strong pests and weeds may be more harmful to other plants and remove nutrients within the soil, in turn reducing the yield of agricultural crops. The benefits of these characteristics are seen in Argentina according to Pelletier (2010) as they use glyphosphate resistant soybean which allowed the comeback of this crop, as the soil was severely damaged from monoculture (The cultivation of a single crop in a defined area).... ... middle of paper ... ...
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).
