Publisher's Synopsis
The purpose of this module is not to assess whether GM crops are good or bad-or whether they require additional regulation- but rather to provide a useful resource for promoting student understanding of specific scientific ideas and the value of science in thinking through environmental issues. To help teachers tap the potential of using GM crops as a learning context and access the resources they need more readily. - Genetic engineering involves the manipulation of genes within a species, and may also involve the transfer of genes-and thus the characteristics governed by those genes-from one species to another. Genetic engineering goals in plants include flower color and in agriculture include improving crop production and introducing new traits, such as enhanced nutrients, temperature resistance, or the ability to grow in saltier soils. Certain characteristics may allow a genetically modified (GM) crop to be grown, harvested, or shipped at lower cost or with less damage and may allow the crop to be grown using less pesticide. In some cases, GM crops may yield entirely new products that are not normally derived from traditional crops-such as medicines. Supporters of this technology point to the potential of GM crops to improve human health and increase environmental protection. However, some concerned groups and individuals have argued that the risks of GM crops may outweigh their benefits. These groups urge avoiding GM crops or, at the very least, subjecting them to more rigorous scrutiny by government regulators. -
