Quality or
quantity
You didn't ask for it, and you might not
know about it. But you've probably already eaten some of it. It's genetically
engineered food.
Perfectly
round tomatoes all exactly the same size, long straight cucumbers and big fat
chickens are now a normal part of our diets.
They are made that way by genetic
engineering - not by nature. Their genes have been changed.
Every living thing has genes. They are passed on from
generation to generation. They make sure that humans give birth to humans and
cows give birth to cows. They also make sure that a dog cannot give birth to a
frog or an elephant I to a horse. Genetic engineers take genes from one species
- for example, a scorpion, and transfer them to another - for example corn. In this way a new life
form is created.
Genetic engineers put duck genes into
chickens to make the chickens bigger. They put hormones into cows to make them
produce more milk. They put genes from flowers into soya beans and from
scorpions into corn. This does not make them cheaper, tastier or healthier. It
makes them easier and faster for the farmer to grow.
The effects of genetic engineering on our
health are not known. Many of the genes which are used - such as those of
scorpions, rats, mice and moths - are not part of our diet so we do not know
how dangerous they may be. For example, people can develop allergies to food
which has been genetically engineered.
The
effects of genetic engineering on the natural world may be disastrous. The
engineers may create life forms - monsters -that we cannot control. The new
life forms have no natural habitat or home. They will have to find one, fight
for one - or kill for one.
Some people believe, though, that genetic
engineering could be the solution to the problem of famine. Plants which grow
faster, or cows which produce more milk, can save the lives of starving people.
We would all like a better, healthier and
longer life, and genetic engineering might give us this. On the other hand, it
may be a dangerous experiment with nature. In the story, Frankenstein created
such a terrible and dangerous monster that he had to destroy it. We must make
sure that it remains a story - and no more than that.
