into their DNA by genetic engineering techniques.
Scientists always want to produce some kinds of food that can combine many useful properties together.
PropertiesThe GM food’s DNA has been
changed, may be added or deleted some

Latest Situation--AdvantagesFaster growth productivity increases provide enough food pests and insects resistance avoid usage of pesticides and insecticides environment friendlyHerbicide tolerancemore nutritional value Longer shelf life shipped long distances
Latest Situation--Disadvantagesend food diversityReduced effectiveness of pesticidesSuperbugscause an allergic reactionUnknown effects on human healthPlay the role of ‘God’
Latest Situation--Development1994 first apply the GM technology to foodpopular GM food can be found everywhereGM crops are allowed in China European Union: some crops
PredictionMore GM food developedPeople will explore more to GM foodPeople will be more open to GM foodBut still many concerns to GM foodGM food cannot replace traditional food
