...Advantages and disadvantages of gm crops The continuously growing human population poses a great challenge to the farming industry. For centuries humanity has selected the best and most suitable crops for the environment they were living in, nowadays with over 800 millions of people being undernourished the pressure to find a better way to feed the population has never been higher (FAO, IFAD and WFP. 2014). Since the first genetically modified crop was introduced in the market in 1994 (James, C. and A.F. Krattiger. 1996.) the debate over GM crops has never stopped.

In fact, I categorize it as a life changing decision. For instance, this decision is like most major decisions people make.
