GM Food~Plants2 What is GM Food? GM food stands for Genetically Modified Food GM food is food with genes modified. Genes can be transplanted by taking out useful pieces of DNA from one organism and merging them with the DNA in another organism. Through this process the quality, the nutrient value, the yield or the resistance against pest of the plant will increase. Hence the food supply and the standard of life of human will be increased.
GM Food~Plants3 Common GM Food Tomato Maize Pasta Cabbage
GM Food~Plants4 Why produce GM food? To improve the quality of food To improve food production to feed the world To strengthen the resistance against pests To cope better with climatic changes To minimize the cost of production To minimize loss during transport and storage
GM Food~Plants5 Is GM food harmful? Will it affect our health? Will it affect the eco-system? Will it have harmful side-effects? Will it reduce consumer choices?
GM Food~Plants6 Will GM food incur Health Problems? Will we suffer from toxins produced? Will we inherit the toxin-producing genes? Will it cause allergic reactions?
GM Food~Plants7 Will GM food incur Health Problems? GM food is consumed as DNA molecules. As human body has been coping perfectly well with foreign DNA for millions years. No harm is proved at this moment.
GM Food~Plants8 Harmful to eco-system? Will it affect the growth of other plants? Will living things lose their living environment? Will it create strange species?
GM Food~Plants9 Any side-effects? Will genes used to modify crops jump the species barrier? Can the possible DNA mutation be controlled?
GM Food~Plants10 Religion and choice? What happens if vegetarians eat food which is genetically engineered with an animal gene? Will it repel choice of food?
