Bt brinjal: Good or bad?

 Advantages :

The key argument used by those who support BT brinjal is that it will boost yields while reducing dependence on pesticides. On average, a brinjal crop undergoes between 50-80 rounds of pesticide spraying.

This is said to give the Brinjal plant resistance against lepidopteron insects like the Brinjal Fruit and Shoot Borer (Leucinodes orbonalis) and Fruit Borer (Helicoverpa armigera). It is reported that upon ingestion of the Bt toxin by the insect, there would be disruption of digestive processes, ultimately resulting in the death of the insect.


Some scientists have been opposing it, arguing that the genes were toxic and would affect the health of the consumers. Several studies on Bt crops in particular and GM crops in general show that there are many potential health hazards in foods bio-engineered in this manner. GM-fed animals in various studies have shown that there are problems with growth, organ development and damage, immune responsiveness and so on.
