The reading passage gives an overview of advantages and positive consequences of Genetically Modified Foods (GM). These are developed in laboratories using molecular biology techniques. It provides resistance to cold, drought, pests, produce higher yields, etc. Also, GM foods reduce need for toxic pesticides and man-made fertilizers. More importantly, GM foods promise to meet higher demand of food using the best techniques. The lecture focuses on the negative impacts on three major fields. The professor makes the first point by stating negative impacts on environment. She claims that although GM foods provide resistance to various defects and increase crop production, it introduces urbsides weeds in the area surrounded by GM crops. These weeds are impossible to eradicate. Also, pollins of these plants has higher mortality rates in butterflies. When theses pollins are blown nearby, they destroy butterfly population. The professor in the lecture makes the second point by stating adverse effects on human health. GM foods cause new allergance. Due to that new allergic reaction take place in human body. These reaction may carry serious risks. A lot of laboratory work is needed to tackle this problem. Finally, the professor states that GM foods spend a lot of money to demand. Moreover, small income farmers cannot afford these GM plants or foods. In short, around one third of farmers cannot afford these techniques. In this way, GM foods extend or widen gap between rich and poor. In general, the professor in the lecture induces risks which are bounded with GM foods. She states adverse influences of these foods on Environment, health of human and economy. In sum, the professor casts doubt on the points stated in the reading text.
