Agricultural biotechnology improves crop plants by providing built-in
protection against diseases and insects, and by instilling herbicide
tolerance, which creates opportunities to produce more and better
foods in a sustainable way. Following are some of the current benefits
of biotechnology, and opportunities for the future.
Fewer Pesticides
Agricultural biotechnology promotes the sustainability of natural resources.
The built-in protection against disease and insects reduces the need
to apply conventional insecticides, thereby reducing handling, exposure
and potential spillage. For example, Bt cotton has reduced pesticide
usage by an estimated two million pounds since its introduction. Herbicide-tolerant
plants also reduce usage of older, less efficient soil-applied herbicides.
Reduced Soil Erosion
The use of crops produced through biotechnology can contribute to a
decrease in erosion because harmful weeds are controlled while the crop
thrives, thereby promoting no-till and conservation tillage systems.
These tillage systems are effective for helping to save the soil, conserve
soil moisture and nutrients, preserve earthworm populations, and reduce
sediment runoff into watersheds.
More Food, Lower Costs
Through biotechnology, varieties of crops can be enhanced to enable
farmers to produce more food at lower costs. Enhanced crops make it
possible to obtain higher crop yields by effectively controlling disease,
insects and weeds that cause extensive crop loss and damage. Higher
yields of biotechnology crops have been reported by a number of respected
sources, including the World Bank, Nuffield Council on Bioethics, and
a joint consultation of the Food and Agriculture Organization of the
United Nations (FAO) and the World Health organization (WHO).
More Efficient Use of Farmland
By easing crop damage and disease, improved pest controls allow for
the more efficient use of farmland, which is critical to the protection
of natural habitat for biodiversity. According to the House Subcommittee
on Basic Research, which conducted comprehensive hearings on agricultural
biotechnology, "Crops that can withstand drought conditions, high
salinity, or toxic materials, for example, could enable populations
living in currently non-arable regions to farm their land, reducing
the pressure on other regions of the world, such as rainforests, that
are currently being converted to farmland."
Fight Disease, Better Nutrition
Biotechnology crops can improve
the nutritional value of foods, which can fight disease and malnutrition.
Agricultural biotechnology has created opportunities to develop plants-called
plant-made pharmaceuticals-that can deliver medicines and vaccines.
Also, scientists have developed a new strain of rice that naturally
produces the protein that creates Vitamin A and iron. In addition
to its effectiveness against maladies such as Vitamin A-induced blindness,
which affects an estimated 200 million people, this product could
be used to cure anemia and other ills that afflict hundreds of millions
of people.
