GENETIC ENGINEERING

Imagine a world full of 'mini Hitlers' seeking world domination, killing millions as their
solution to establish a superior race or bunch or 2 headed humans eating a pig with 6
legs. These scenarios may sound like something out a science fiction novel, but this is
the kind of things that people think about when they hear the words 'genetic
engineering'
Genetic engineering is now an important part of this world. It is used to cure diseases,
develop food that grows faster and food that's healthier. Without genetic engineering it
will not be possible to feed the 10 billion humans expected by the year 2030. Only by
using this new technology can we increase the food production enough so that it is
possible to feed this growing world. This can be done by producing plant varieties that
is more precisely adapted to local conditions. This also helps poor farmers by reducing
their expenses such as pesticides. 
In developing worlds there are over 100 million children with vitamin A deficiency
causing huge problems such as blindness. These people eat mainly rice and rice has no
vitamin A. Right now the only way they can get enough vitamin A is by costly supplements
that doesn't reach everyone. So scientists are genetically engineering rice so that it
contains vitamin A, and this rice seed could be distributed to the poorest areas of the
world, a brilliant and simple idea. 
So how can consumers living in developed world benefit from plant biotechnology? Using
modern biotechnology scientists have already produced food with improved flavour, food
that is better for health and food with better qualities. Examples of these are apples
and sweet corns that are insect resistant, frost resistant strawberries and seedless
grapes. 
One of the main reasons why people oppose genetic engineering is that they think
biotechnology is an imprecise science and so it will likely to result in unanticipated
outcomes and dangerous surprises. But did you know that people have been cross breeding
plants and animals for thousands of years? And every time they do this they are randomly
recombining up to 40,000 genes. If using biotech scientists are just moving 1 or 2
specific genes, and the effects can be monitored and tested more easily. So in comparison
genetic engineering is a lot safer than traditional cross breeding.
Another important aspect of genetic engineering is its medical purposes. For example
cystic fibrosis maybe cured if a gene can somehow enter the cells that line that lungs,
it will begin producing the critical proteins that CF patients lack. Scientists are
working on this right now and some patients receiving this treatment have already been
able to produce this protein in small quantities. 
Genetic engineering and the knowledge about the effects of DNA variation among
individuals can lead to revolutionary new ways to treat and even prevent thousands of
disorders that affect us. Learning about non-human organism's DNA can also help us
understand their natural capabilities which can be applied towards solving challenges in
health care, energy sources, agriculture, and environmental cleanup
