Should

farmers

be

concerned

with

agricultural
biotechnology
?

What

is

Agricultural
Biotechnology
?


An advanced technology that allows
plant breeders to make precise genetic
changes to add beneficial traits to the
crops we rely on for food


The tools of modern biotechnology
allow plant breeders to select genes that
produce beneficial traits and move them
from one organism to another.

How long has genetic engineering been used in
agriculture and food production?



The first food products of biotechnology
-

an enzyme
used in cheese production and a yeast used for
baking appeared on the market in 1990.


In 2001, an estimated 5.5 million farmers grew
biotech crops on 130 million acres in about 15
countries, led by the U.S., Canada and Argentina.

Why

is

it

being

used

in
our

food

Supply
?


Virtually all of the biotech crops on the market
today were developed to reduce crop damage
by weeds, diseases and insects


Genetic modification improves


yields and reduces the need


for pesticide applications,


saving the farmer time and money.


Potential benefits



Safer food supply for consumers


Less impact on the environment


Less expensive food production


Crops less vulnerable to insects,
diseases and weeds


Crops with higher/greater nutritional
content


Crops developed as production
vehicles for medicines and vaccines to
prevent disease

Potential Risks


Farmworker

and consumer safety


Environmental effects on plants, animals and water systems


Genes moving from genetically engineered crops into wild
plants


Pests eventually developing resistance to pest
-
resistant crops


Introduction of allergy
-
causing compounds into foods
