Agriculture & technology working model

Modern technology is already being used in agriculture. The best example is the use of gene technology or what’s popularly known as agricultural biotechnology in developing drought and herbicide resistant crops. Through genetic engineering, scientists have been able to introduce traits into existing genes to make crops resistant to drought and herbicides. One good example is the use of Bacillus Thuringiensis, commonly known as Bt. Bacillus Thuringiensis, is a bacterium that dwells in soil. It acts as a reservoir “of cry toxins and cry genes for production of biological insecticides and insect-resistant genetically modified crops.”

How has gene technology benefited agriculture? Genetically engineered crops such as corn, soy and cotton are being cultivated in more than 21 countries. In the United States, for example, about 60 per cent of corn is genetically modified to resist corn borer, a common pest that feeds on the corn stem. Farmers have embraced genetically modified corn because it yields high. The fact that this corn variety contains Bacillus Thuringiensis saves farmers money that could have been spent buying pesticides.

Developing countries such as South Africa, India and Pakistan have embrace modern agricultural biotechnology. In South Africa, for example, farmers are growing Bt. cotton. Reports indicate that Bt cotton yields high that conventional varieties. The story is the same in India. Bt. cotton is proving profitable to farmers.

The problem with much of modern technology, esp with agriculture is that we endeavor to do the WRONG thing as right as we can. We wish to feed huge populations with mono cultural practices based on overpopulating crops for the biggest (money) harvests of perfect food. The soil suffers, the water suffers, and the food is not as nature intended. It has been said that food today when compared to the past and in terms of the economy and what we have in our pantry, is cheaper than it has ever been. So much for America but not so for the rest of the world, and soon to be not so here. What a logistical nightmare; do what I should and grow less with a somewhat lower but organic sustainable product or do what is poor for the environment in the name of $$$ (666). Biotechnology may be the last hope but the uninformed refuse to even try a genetically altered apple. Give that apple to a starving person and see them smile. How hungry do you have to be to overcome your blissful ignorance?

Technology has greatly affected food production... obviously, the use of machineries and alike sped up planting/harvesting processes as well as processing. At the same time, advances in genetic engineering have explored the possibilities of improving the quality of food. a good example is canola oil. Canola oil comes from rapeseed which has toxic/poisonous compound (erucic acid). Genetic manipulations reduced this poisonous materials hence we are safely consuming the product. Crops are more resistant towards environmental stresses and production rates are continuously increasing...

Genetic engineering

Genetic engineering, also called genetic modification, is the human manipulation of an organism's genetic material in a way that does not occur under natural conditions. It involves the use of recombinant DNA techniques, but does not include traditional animal and plant breeding or mutagenesis. Any organism that is generated using these techniques is considered to be a genetically modified organism. The first organisms genetically engineered were bacteria in 1973 and then mice in 1974. Insulin producing bacteria were commercialized in 1982 and genetically modified food has been sold since 1994. Producing genetically modified organisms is a multi-step process. It first involves the isolating and copying the genetic material of interest. A construct is built containing all the genetic elements for correct expression. This construct is then inserted into...
