genetically engineered foods
more efficient trading

Explanation:

This commentary is a face-to-face debate between two almost opposite positions regarding the application of genetic engineering in agriculture and food production. Seven questions on the potential benefits of the application of genetic engineering in agriculture and on the potentially adverse impacts on the environment and human health were posed to two scientists: one who is sceptical about the use of GMOs in Agriculture, and one who views GMOs as an important tool for quantitatively and qualitatively improving food production.

Since the mid-1990s, the release of GMOs into the environment and the marketing of foods derived from GM crops has resulted in a scientific and public debate. Despite the potential benefits of the application of genetic engineering in agriculture in order to improve the quality and the reliability of the food supply, since the beginning, public and scientific concerns have been raised in many parts of the world about environmental and food safety of GM crops.

Two major different points of view have been expressed by the community: on one hand, recombinant DNA technology is seen as a potent tool for enhancing crop productivity (first generation GMOs) and food quality (second generation GMOs) or “drug factories”, for the production of vaccines and/or therapeutic medicines (third generation GMOs). GMO supporters point to evidence that GMOs must be considered essential for promoting sustainable agriculture, as they may be able to reduce agriculture’s environmental footprint, reducing the use of pesticides, saving fossil fuels, decreasing CO2 emissions and conserving soil and moisture (James 2011). Supporters also consider GM crops indispensable in facing the severe global food and nutrition security problem in developing countries: although GM crops are not presented as the “absolute solution”, it has been stated that they could undoubtedly make a significant contribution to an array of measurements and incentives to this constantly growing problem (Conner et al. 2003).
