We have been living in the nuclear age now for over half a century. Since
the first atomic bombs were developed, nuclear technology has provided
governments with the ability to totally destroy the planet. Yet the technology
has been put to positive use as an energy source and in certain areas of
medicine.
To what extent is nuclear technology a danger to life on Earth? What are
the benefits and risks associated with its use?
Model Answer:
These days, many people are afraid of nuclear technology because of the
dangers associated with its use. In my opinion, although it is true that nuclear
weapons pose the greatest threat to life, the use of nuclear technology for
peaceful purposes also carries some serious risks.
Nuclear power stations provide an important source of cheap power for many
industrialised nations and some developing countries. However, there is always
the danger of radiation leaking from these plants. Even though safety
precautions are taken, there have been numerous disasters such as the explosion
of a nuclear plant in Russia not long ago.
Nuclear technology is even used to help cure some diseases such as cancer.
Radiation can be applied to the body to burn away cancerous cells. This is,
however, a dangerous procedure, and the application of radiation is almost
always painful and not always successful.
The most worrying aspect of nuclear technology, though, is its use for
military purposes. Enough atomic bombs have already been built to completely
destroy the planet, and the real danger is that one day some country will start
a war with these weapons. Too many countries now have the technology required to
make such bombs, and there is currently much debate about how to control the
situation.
In conclusion, nuclear technology certainly has positive uses, but is,
nonetheless, dangerous. However, it would have been better if it had never been
used to create nuclear weapons. If life on Earth is to continue.
