This document discusses genetically modified foods (GMFs) and outlines some of their potential risks and benefits. It begins by differentiating genetic engineering, which alters an organism's DNA, from traditional crossbreeding. The document then provides examples of GMFs like crops modified to be pesticide-resistant. Both the projected disadvantages of GMFs, like unpredictable genetic effects and increased resistant pests, and advantages, like higher yields and need for less water, are listed. It concludes by asking readers to evaluate the most important risks and benefits of GMFs.

27. PROJECTED DISADVANTAGES PROJECTED ADVANTAGES
Need less fertilizer Irreversible and unpredictable
Need less water genetic and ecological effects
More resistant to insects, disease, Harmful toxins in food from
frost, and drought possible plant cell mutations
Grow faster New allergens in food
Can grow in slightly salty soils Lower nutrition
May need less pesticides Increase in pesticide-resistant
insects, herbicide-resistant
Tolerate high levels of herbicides weeds, and plant diseases
Higher yields Can harm beneficial insects
Less spoilage Lower genetic diversity
30. There are several potential
risks of GM food to Human
Health, namely:
31. Direct health effects (toxicity);
Tendencies to provoke allergic
reaction;
Specific components thought
to have nutritional or toxic
properties;
32. The stability of the inserted
gene;
Nutritional effects associated
with genetic modification; and
Any unintended effects which
could result from the gene
insertion.
33. Which two disadvantages
and two advantages (of
GMF) do you think are the
most important? Why?
