Final answer:
The major limitation of GMO production is the potential risk to human health and the environment. Concentration of seed-markets by a few companies can negatively impact seed prices and farmers. Genetic engineering has limitations in terms of advancing nutritional quality or preventing plant diseases.
Step-by-step explanation:
The major limitation of GMO production is the potential risk it poses to human health and the environment. One concern is the possibility of producing new allergens in GM foods. However, it is important to note that traditional breeding practices can also produce genetic modifications and new traits that may pose similar risks.
Another limitation is the concentration of seed-markets by a few companies, which can lead to reduced free market competition and negatively impact seed prices and farmers.
Additionally, while genetic engineering can offer benefits such as improved crop yields and disease resistance, there are limitations in terms of advancing nutritional quality or preventing plant diseases.
