Can biotech crops harm beneficial insects or lead to a loss of biodiversity?
University researchers have shown that Bt crops do not threaten populations of Monarch butterfly, other butterflies, or other beneficial insects and animals. The Bt proteins used in biotech crops were chosen because they are only effective against specific pests. In fact, they are the same natural pesticides used by organic producers. Researchers have shown that Bt proteins do not accumulate in the environment, nor harm soil ecology and fertility. In fact, numerous published studies demonstrate Bt proteins from Bt crops are rapidly degraded in the soil environment and do not negatively impact soil organisms. An overwhelming majority of experts agree that biotech cropping systems are good for the environment.
