Spores and crystalline insecticidal proteins produced by B. thuringiensis have been used to control insect pests since the 1920s and are often applied as liquid sprays. They are now used as specific insecticides under trade names such as DiPel and Thuricide. Because of their specificity, these pesticides are regarded as environmentally friendly, with little or no effect on humans, wildlife, pollinators, and most other beneficial insects, and are used in organic farming.
Seems to me whether or not something is safe or harmful, to humans or the environment, should not be based on what people 'believe' but instead based on scientific studies. Putting our beliefs over science is idiotic and reckless...and arrogant...
