Crop residue

widely used was DDT; it was favored for its ability to get rid of pests against agricultural and human health. Pesticide use was very liberal and many pests became resistant to pesticides, this caused non-targeted plants and animals to be harmed, and residue started to show up in unexpected places. (Delaplane, 2) Rachel Carson wrote the novel Silent Spring in 1962, the public was shaken. In Silent Spring Carson wrote about the environmental effects of careless use of pesticides. (Delaplane, 2)…

outcome? There are now problems with the GMO crops that posed no problem to our environment. The promise of herbicide tolerant crops were of easy weed control and fewer chemical applications, this is now not the case. These crops require fertilizer, and our now producing weeds that are resistant to the common herbicides. These crops are now herbicide tolerant and require the use of stronger and different herbicides to control them. In addition to the crops being herbicide tolerant, they also…

Finally, biodiversity, which is critical in all ecosystems and to the sustainability of all species, is put at risk by GMO foods. GM crops are generally planted in a monocrop fashion, which means that many heritage seeds are no longer used. The nature of GMOs means fewer weed flowers and, therefore, less nectar for the pollinators such as bees to choose from so the crop will be pollinated more instead of weeds being pollinated. Hurst also says “The combination of herbicides and genetically…

The 1st generation is the easiest to come across, it is crops which contain cellulose and lignin. Traditionally these were the only organic sources tested to be used for biofuel. Switchgrass, corn and rapeseed are all a part of this category. The 2nd generation consists of by-products from the 1st generation…

taken to keep a field "all natural". Crop diversity is a must for organic farming. Conventional farming focuses on mass production of one crop in one location, a practice called monoculture. The science of agroecology has shown benefits of multiple crops in the same space. Organic farming relies heavily on the natural breakdown of organic matter, using techniques like green manure and composting, to replace nutrients taken from the soil by previous crops. This type of farming uses a variety…

chemicals and supplements out of the growing process results in healthier and more nutrient rich foods, but why? Alyson Mitchell, Ph.D., an associate professor of food science and technology at the University of California, Davis explains how growing crops naturally results in these findings. Mitchell states that “with organic methods, the nitrogen present in composted soil is released slowly and…

years. The GMO insecticides can transfer into the DNA of bacteria living inside of us, proven to appear in the fetus and blood of pregnant women (10 Reasons To Avoid GMOS). The leftover toxic chemicals from the insect killers have been known to leave residues in the modified foods. These harmful substances can stay in our digestive system and affect us in many greater ways than we believe. Obviously, GMOs have created a large number of health related problems due to the consumption of their…

the risk of food based allergies, The potential of any new food to induce allergic reactions has been seized upon by critics of GM crops, which contain foreign or engineered proteins, and has been promulgated as…

Rachel Carson had many great reasons for writing the book Silent Spring. The main theme of the book was to prove the effects of the careless spraying and dusting of people, crops, fields, and forests with harmful chemicals in the mid 1900s. This book was published in 1962, so a lot of the “new” advancements and findings are outdated as of 2015, however this book marks the important history of what happened when humans interfered with nature by using chemicals, and how that affected the…

on the vitamin itself. This report specifically contains research on the Zambian environment looking into the seasonal barriers concerned with the production of foods grown in the refugee camp, the efficiency of the crops being produced, the effect of climate and environment on crops, the contamination of food and also how the food is stored and transported. It aims to increase the overall health of the refugees which can decrease the possibility of disabilities due to malnutrition such as…
