GM Debate
Are GM crops a good thing? Many people who object to the use of GM crops argue that there is a potential for "superweeds" to arise through cross-pollination with herbicide resistant crops, or that "superbugs" will evolve to be resistant to the toxins in pest-resistant crops. Many are concerned about potential allergic reactions to novel proteins, antibiotic resistance arising from the selectable markers used to develop the crops, or other unforeseen effects on public health. Some voice concerns that we have not done enough research to fully understand the implications of altering the planet's plant diversity.
Proponents of GM crops and foods argue that these crops are beneficial for the environment because they reduce the use of herbicides and pesticides that are toxic to the environment and human health. In addition, GM crops may preserve arable land by reducing stresses on the land, improve the nutritional value of food for developing countries, and allow crops to be grown on previously nonarable land.
Regardless of where your students stand on the GM debate, won't they be interested to know how much of the corn- or soy-based foods they eat have been genetically modified?
