Genetically Modified Foods, Pros and Cons.
Genetically modified foods (GMs)are becoming increasingly
coirtmon in many countries. However, before one opts for any of
these foods, it is very important to know about their pros and
cons.
There are a variety of reasons for developing GMs. For
instance, some foods are genetically modified to prevent the
occurrence of allergies after consumption, while some are
developed to improve their shelf life.
Though the seeds of GMs are quite expensive, their cost of
production is said to be lesser than that of the traditional crops
for these foods do have natural resistance towards damaging pests
and insects. This reduces the necessity of exposing crops to
hazardous Chemicals. It is also said that GMs grow faster. Due to
this, productivity increases, providing the population with more
food. At times, GMs crops can be grown at places with unfavorable
climatic conditions whereas a normal crop can grow only in
specific season or under some favorable climatic conditions.
The biggest threat caused by GMs is that they can have
harmful effects on the human body. It is believed that they can
cause diseases which are immune to antibiotics. Moreover,
according to some experts, people who consume such foods have high
chances of developing câncer. Besides, not much is known about
their long-term effects on human beings.
In many countries, manufacturers do not mention on the labei
that foods are genetically modified because they think that this
would affect their business. However, this is not a good practice
as consumers do not get the chance to decide whether they should
really opt for these foods, Experts are of the opinion that with
the increase of genetically modified foods, developing countries
would start depending more on industrial countries because it is
likely that the food production would be controlled by them in the
time to come.
