Only six European Countries have GM crops, the total area planted with GM crops in the continent has decreased by 12% in one year. At the end of 2008 Germany in banned their cultivation. Europe seems to stand against these crops whereas in developing countries, like China and Brazil GMOs grow. Those who support GMO’s claim that their use increases the field’s yield, but the downside is that farmers have to use patented seeds that they have to buy every year, from the Corporations. Then there is the problem of contamination: the farmers who decide to be GM-free are likely to have a GM crops anyway if their field neighbours one that is.The challenge for the future is not easy, according to UN estimates the world population will grow by 34% and in 2050 the world will have to feed 9.1 billion people. According to some, only GMOs cultivations can meet this need, according to others , instead, we must focus on quality and food welfare for all, only in this way will the world save itself.
