Genetically Modified Pest-Protected Plants: Science and Regulation

---

Transgenic pest-protected crops were first commercially planted in
the United States in 1995. Since then the acreage planted to transgenic
crops has increased rapidly with some 70 million acres being grown in the
United States, and 98.6 globally in 1999. Of this acreage, a large percentage
(for example, 30 million acres in the US in 1999) is planted
with transgenic pest-protected crop varieties containing the Bacillus
thuringiensis (Bt) gene which confers protection from certain insect pests
and with varieties that are herbicide-tolerant. In 1998, about 25% of the
US cotton acreage and 21% of the corn acreage was planted with varieties
containing Bt genes.

This increase in acreage planted in transgenic crops has largely resulted
because of benefits produced to farmers. Many farmers are growing
transgenic crops because they either produce more effective control of
serious pests than conventional chemical treatments, or they provide control
at lower costs than conventional treatments, or both. The growing of
some Bt crops has been accompanied by a reduction in the amounts of
chemical pesticides previously used on these crops. This has produced a
side benefit in terms of reducing exposure of humans and other nontarget
organisms to these toxic chemicals and lessening the contamination
of air and water.

Given the rapid increase in plantings of transgenic varieties, concerns
have been raised about the ecological and human health risks that might
be posed by these crops. Although these risks might not in principle
differ in type from those associated with other conventionally-bred pestresistant
varieties or chemical pesticides, they nevertheless have become
a focus of attention by several groups who are concerned by potential
risks that might be posed by transgenic breeding methods. This concern
has been magnified in Europe and other parts of the world where consumer
resistance has been increasing against food products produced
from transgenic plants.
