Hi Ella, I think there are three big challenges bio-engineered crops face:
1. Addressing the intra-species potential to introduce an unintended genetic variable that remains hidden before expressing itself in later generations of crops.
2. Defining what is the right duration for testing the output of genetic engineering to assure the public of the safety of the product.
3. Educating the public about the science of bio-engineering so that consumers understand how this compares to “natural” or “human” selection in the process of improving crops for human and domestic animal consumption.
