This robs organic farmers of the use of their safe insecticide. The use of Bt in plants can lead to ecological imbalances. Researchers in Switzerland have shown that Bt crops have killed lacewings, a beneficial insect that feeds on other agricultural pests and provides food for birds. Research in Scotland showed that the lifespan of ladybirds was reduced by half when they ate aphids that had fed on Bt potatoes. They also laid fewer eggs.
Ladybirds are a very beneficial insect.
They have been done to allow the use of more pesticides. This will lead to more pollution of our rivers and waterways and it also means that we will be eating more pesticide in our food. Similarly, with the Ingard cotton we will be eating BT toxin in our food. There has been no independent long term research done on the effect of eating these 3contaminants. We also have the example of the damaging health and environmental effects of DDT and dioxin.
