
The
beginning
stage
of
genetic
engineering experiments is cousidered to
be early 70s, when the first genetically
modified organisms were created. They
were various viruses, mikroorganisms,
plants and animals with several new
qualities.
Objectives of creation of
genetically modified food



Plants improvement for bigger harvest.
Plants improvement for comfortable using.
Way to solve the hunger problems in the
world.
Pluses of genetically modified
food

Plants are more resistable against:




Frost
Drought
Bugs
Diseases
Plants for more comfortably using, like, onions
that do not make eyes with tears.
For every climate zone suitable plants variety.
Bigger harvests and plants full of nutrients.
Esiear plant transportation and preserving.
Possible minuses of GM food


Genes of the improved plants could
transfer to wild plants creating mutants
which could reduce biological variety and
make the environment worse.
You can not ignore the negative influence
of GM food on people`s helth, the
consequences probably will be observed
after several generations. GM food can be
toxic or allergic for people.
Corn

First time GM corn
was cultivated in
1997 in the USA
and Canada. It is
mostly used for
forage
and
production
of
starch.
Tomatoes

The first version of
GM tomatoes was
cultivated in 1994 in
the USA. Tomato is a
GM food symbol for
many years.
Papaja

Papaja which grows in
many
tropican
countries
is
very
popular in Africa and
islands. The harvest
has reduced because
of diseases. The first
GM papajas were
cultivated in 1999 on
Havaian islands.
Potatoes

GM potatoes are more
resistable against frost,
in some potatoes there
are 1/3 more proteins
and amino acids. But
people are afraid of GM
potatoes because all of
scandals of their negative
influence on mammal
organisms.
Rice

Rice is one of the most
popular food in the
world, that is why
scientists in 2000 made
rice, that are full with
vitamin A.
Apple

Scientists are working to
make appletrees imune
against diseases that are
common in Europa. That
is why green, red and
yellow versions of GM
fruit are not allowed to
sell
in
shops
and
markets.
Banana

Every year Euoropean
countries buy 4 milion
tonn bananas from
trops which aren`t
GM. GM bananas are
infected with fungus
and in the future
scientists will make
superstrong bananas.
Soya (soybean)

Scientists trying to
refine soya which
nutrients accidentally
added a gene from
Brazilian nut, witch
can cause an allergy
to many people.
It is allowed to spread the approved food in EU
countries. The food contains, consists of or is
got from 7 GM rape sorts, 9 GM corn sorts, 2
kinds of GM cotton, and one kind of GM soya.
One of the main food grops obtained from GM
rape, corn and cotton is oil.
