Transgenic Corn - It keeps pests away, but what effect does it have on the ecosystem?

For centuries farmers have had problems keeping their crops from succumbing to pests. In the last few years a genetically engineered corn that contains a toxin protecting it from pests has been created. It includes a gene from the micro-organism Bacillus thuringiensis, Bt. In Bloomington, Indiana, parts of the toxic corn are washing into nearby streams, killing a type of fly that is eaten by much the aquatic life. This is a major downside to the transgenic corn. These flies are not only a major food source, but they help control the algae population in the area.
