The world's first commercial production of Genetically modified food (GMF) is delay the maturity of Genetically modified tomato,which was put into the United States market in 1994. There is no denying the fact that the number of GMF is steadily increasing in the 21st century. So,what is the so-called GMF?
GMF is a kind of food that is embedded foreign gene in the genome of the species by genetic engineering technology to meet human needs,including transgenic plant food,transgenic animal food and transgenic microorganism food. There has been a controversy that whether the GMF should be banned.
On one side are the GMF supporters,who suggestion GMF has been no sign of major health or environmental problems. This kind of food has many advantages:increase crop yields, reduce production costs,enhance the ability of anti-virus and so on. GMF is usually cheaper and easier to plant than traditional food,in this way,we can get more people to eat and live. On the other are the opponents,who believe that GMF is harmful to our health because it's potential threat,such as some species may be affected by the drift of genes,GMF may cause allergic reactions. So,we should not promote and eat GMF.
In my point of view,GMF is a double-edged sword. Mature GMF can benefit mankind and reduce hunger,but we should take a cautious attitude to the immature GMF.
