Discuss the likely advantages and problems arising from the introduction of genetically modified agricultural crops.

 

  Genetically Modified food (GM) is most commonly used to refer to crop plants created for human or animal consumption, using the latest molecular biology techniques. These plants have been modified in the laboratory to enhance desired traits such as increased resistance to herbicides or improved nutritional content. Genetic engineering can create plants with the extract desired trait, both accurately and rapidly. For example frost can destroy sensitive seedlings, an antifreeze gene from cold water fish has been introduced to plants such as tobacco and potatoes, and with this anti freeze gene these plants are able to tolerate the cold temperatures that would normally kill unmodified seedlings.

  Crop losses from insect pests can be staggering resulting in devastating financial loss for farmers and starvation in developing countries. Farmers typically use chemical pesticides annually. Consumers do not wish to eat food that has been treated with pesticides because of potential health hazards. Growing GM food such as Bacillus thuringiensis (B.t) corn could eliminate the application of chemical pesticides. B.t is a naturally occurring bacterium that produces crystal proteins that are lethal to insect larva; B.t crystal protein genes have been inserted into corn, enabling the corn to produce its own pesticides against insects.

There is also a risk that inserting a gene into a plant may create a new allergen.

  The world population is estimated at around 6 million it is predicted that in the next 50 years that the population will double, ensuring adequate food supply for this booming population GM foods has promised to meet this need in a number of ways.  Genetically modified foods have the potential to solve many of the world’s hunger and malnutrition problems, and to help protect and preserve the environment by increasing yields and reducing reliance upon chemical pesticides and herbicides.
