Nowadays, scientists can make copies
of plants, animals and even human beings. We call this cloning. There is
nothing new about cloning at all. Ancient Greeks cloned plants over 4000 years
ago and the first cloned frog appeared in 1968. Twenty-nine years later, in
1997, Dr Ian Wilmut and other fellow researchers from Edinburgh University, Scotland,
managed to clone and adult sheep from a single cell to produce a lamb (Dolly)
with the same genes as its mother. Some people are worried because scientists
started to think about cloning human beings.
Today, we can also use genetic
engineering technology to produce genetically modified food. Scientists can
copy and transfer individual genes from one living organism to another in order
to make plants more productive and more resistant to diseases and pests.
However, some people refuse to eat genetically modified food (GMFs). They
consider that biological products are safer.
