Genetic modification (GM) is in fact far more than a
mere development of selective breeding techniques.
Combining genetic material from species that cannot
breed naturally is an interference in areas which may
be highly dangerous. The consequences of this kind of
manipulation cannot be foreseen.
It seems undeniable that these processes may lead to
major benefits in food production and the environment.
Furthermore, there is no doubt that some medical
advances may have saved millions of lives. However, this
level of technology can contain a strong element of risk.
Our ignorance of the long-term effects of releasing GM
plants or even animals into the environment means
that this step should only be taken after very careful
consideration.
