The GMO Menace provides an excellent overview of the problems with GMO plants and animals. The authors discuss the instability of genetic alterations, the known and possible toxic results, antibiotic resistance, the awakening of dormant viruses (for which we may have little protection), genetic pollution of non-GMO crops, superweeds, destruction of biodiversity, the possible extinction of wild species overcome by GMO species, and increased pesticide consumption (contrary to biotech seed makers' promises). If some of these problems are unfamiliar to you, click through.
