Genetic Engineering is a term that has been
surrounded by controversy since it was first widely discussed
in the early 1990s. With the advances in science allowing
humans to alter genes and the DNA of plants and animals, including
the food that we eat, many are left wondering what will be
the outcome of tampering with nature.

| What is
genetic engineering? |
| Genetic engineering
is a process that allows scientists to create plants, animals
and microorganisms by manipulating genes artificially. Supporters
say the process benefits our food supply because genetic engineering
has the ability to produce pest-resistant plants that stay
fresh longer. They also promote its alleged ability to boost
farm productivity. However, studies show that the unforeseen
dangers of genetic engineering may outweigh the trumpeted
benefits and farm productivity studies show that organic farming
is able to produce greater crop yields over time.

| What is
the difference between genetic engineering and traditional breeding?
|
Traditional breeding involves
mixing genes between plants of the same species. For example,
crossing a rose with another rose to make a new color. Genetic
engineering on the other hand, consists of splicing genes
from any species, be it plant, animal, insect, bacteria, or
even human into another totally unrelated species. One example
would be extracting a gene from an artic fish, such as a flounder,
which produces a chemical with antifreeze properties, and
splicing it into a tomato or strawberry to make it frost resistant.

| What are
the risks of genetic engineering? |
| In 1992, the FDA
declared that genetically engineered foods, a.k.a GMO (Genetically
Modified Organism) are "not inherently dangerous"
and do not require special regulation. But one of the problems
of non-regulation is that developing plants that are resistant
to pests and diseases can create "super pests" and
new strains of diseases that could wipe out whole populations
of organisms. A new gene inserted into a plant could produce
unknown toxins, allergens, and possibly change the nutritional
value of the plant. If a genetically modified organism is
released into the wild, it is impossible to predict if the
organism will breed with other species, overtake another species,
or alter an entire ecosystem. Several studies, as reported
by Eva Novotny of Scientists for Global Responsibility, have
suggested that even animals prefer non-GE food and will actually
avoid eating GE food when given the option. Genetic engineering
is an unnecessary and unpredictable technology. Because regulations
do not require GE food to be labeled, the best way to avoid
it is to buy organic foods or foods that are labeled "Non-GE".
