We describe a bond having one end slightly positive and the other end slightly negative as being polar. Inductive effects. An atom like fluorine which can pull the bonding pair away from the atom it is attached to is said to have a negative inductive effect.
These genetically modified organisms (GMOs) are designed for many reasons, including: pesticide and disease resistance, drought/frost resistance, increased yields, enhanced nutritional content and as a way to produce drugs or vaccines at low cost on a large scale.
I don't think that we need to ban GMO development entirely because it has many positive effects. But the health risks of GMOs are unclear. We don't have long-term studies that prove the safety of Genetically Engineered Food (GMF). Also, the number of cancer cases has been increasing in the World over the last 20 years.
