GMO’s! What can we say about it? Genetically modified foods
doesn’t have that great of a ring to it if you ask me. How people feel about it
differ according to individual preference of course, but what exactly are
GMO’s? How do we label them?
Let’s talk about what GMO foods actually are. They are
genetically engineered foods that have had foreign genes (genes from other
plants or animals) inserted into their genetic codes.
Basically, it’s not just something that we plant into the ground and happen to
spring up with something fresh and unaltered. Genetic engineering allows
scientists to speed the process of farming by moving desired genes from one
plant to another, or even from an animal to a plant or vice versa. If we want to get really technical, the use of b.t.
(Baccilus thuringiensis) genes are used in corn and other crops. It is a
naturally occurring bacterium that produces crystal proteins that are lethal to
insect larvae. B.t. crystal protein genes have been transferred into corn,
enabling the corn to produce its own pesticides against insects.
Pros and advantages of GM crops:
Some of the advantages of GM crops are pest resistance,
herbicide tolerance, nutrition, and cold tolerance. They can keep bugs away
without having to use chemical pesticides, and some crops may provide more
nutrition than it would have otherwise.
Concerns and disadvantages of GM crops:
The concerns with GM crops are that people may have more of
an allergic reaction to them, many children in the US and Europe have developed
life-threatening allergies to peanuts and other foods. Also, we do not exactly
know what kind of harm they are doing to our bodies. It can be harmful to our
health without us knowing it. However, with the exception of allergies,
scientists believe that GM foods do not present a risk to human health.
