In the developing countries crop damage from pests can cause economic loss and starvation for the farmers. As a pre-caution farmer use multiple pesticides to kill insect and because this is hazardous to human health many customers don’t want to eat this food. Also in cases of heavy rainfall the chemical pesticides can run off into a water supply and causing unsanitary environment. An example to eliminate the usage of pesticides and reduce cost of crop in markets is Bacillus thuringiensis (B.t) genes in corn. A B.t is a natural bacterium that creates crystal proteins that are deadly to insect larvae, mainly caterpillars. The B.t in the corn expresses proteins called Cry against insects but are harmless to humans. B.t is described as “the most important techno- logical advancement in insect pest management since the development of synthetic insecticides” because corn holds resistance to a harmful pest, the European corn borer (Ostrinia nubilalis). The B.t genes have also been introduced introduce to other crops for instances potato, beet and cotton. Regular cotton, without the B.t gene is increasingly susceptible to damage by insects and so one quarter of pesticides in the US is used only for cotton. Hence by GM of cotton with the B.t gene the amount of pesticides are used by the farmer decreases. 1038From the Department of Agriculture
To defend against disease genetic modified crops such as tobacco, squash, tomatoes and corn are designed to be virus resistant. For example, over 500 million people in third countries feed on Cassava, a genetic engineered to contain more nutrient and to resist the African cassava mosaic virus. To defend against biological invasion traits are added to various crops such as squash, potato and papaya th...

...for 11,323 heart attack survivors. There is a significant relationship between omega 3 fatty acids and better health. Therefore, genetic modification of fish builds for improved nutrition in humans.
Genetic engineering is used to increase minerals and most important natural anti-oxidant in the food that are produced. Even hormones such as somatotropin (rPST) growth hormone can treat pigs for more meat production and low-fat pork and bovine somatotropin hormone (BSH) enrich milk production in cow. BSH is not harmfully to humans and can be digested by the gastrointestinal tract, thus it is safe. Cows can produce special qualities of milk such as low fat-milk and lactose-free milk, reducing post-milk modifications. From the numerous examples there is excessive correlation that of genetic modified foods and organisms are valuable for human health and quality of food.

Genetically Modified Food And Its Effects On The Environment And Insects Necessary For The Progression Of Crops

- Barbara Kingsolver discusses genetic manipulation through generations of different species in her essay A Fist in the Eye of God. These genetic manipulations occur due to the species acclimating to their environment. Diversity in genes is nature’s survival of the fittest. Only the strongest survive and they pass on their strong traits. With today’s technology, we have the capability of altering genes within a species DNA. This paper examines the detrimental repercussions that GMO 's cause to the environment and insects necessary for the progression of crops....   [tags: DNA, Agriculture, Genetic engineering]
