There’s no doubt that nanotechnology promises so much for civilization. However, all new technologies have their teething problems, And with nanotechnology, society often gets the wrong idea about its capabilities. Numerous science-fiction books and movies have raised people’s fears about nanotechnology ---with scenarios such as inserting little nano-robots into your body that monitor everything you do without you realizing it,or self-replicating nano-robots that eventually take over the world.
So how do we safeguard such a potentially powerful technology? Some scientists recommend that nano-particles be treated as new chemicals with separate safety tests and clear labelling. They believe that greater care should also be taken with nano-particles in laboratories and factories. Others have called for a withdrawal of new nano products such as cosmetics and a temporary halt to many kinds of nanotech research.
But as far as I’m concerned there’s a need to plough ahead with the discoveries and applications of nanotechnology.I really believe that most scientists would welcome a way to guard against unethical uses of such technology. We can’t go around thinking that all innovation is bad.all advancement is bad. As with the debate about any new technology.it is how you use it that’s important.So let’s look at some of its possible uses.
Thanks to nanotechnology, there could be a major breakthrough in the field of transportation with the production of more durable metals. These could be virtually unbreakable, lighter and much more pliable leading to planes that are 50 times lighter than at present. Those same improved capabilities will dramatically reduce the cost of traveling into space making it more accessible to ordinary people and opening up a totally new holiday destination.
In terms of technology, the computer industry will be able to shrink computer parts down to minute sizes. We need nanotechnology in order to create a new generation of computers that will work even faster and will have a million times more memory but will be about the size of a sugar cube. Nanotechnology could also revolutionise the way that we generate power .The cost of solar cells will be drastically reduced so harnessing this energy will be far more economical than at present.
In this passage the author tells us that one problem with nanotech is that___

A. it could threaten our way of life
B. It is misunderstood by the public
C. It could be used to spy on people
D. We only see nanotechology in some books and movies
