Question

How can nanotechnology hurt mankind?

Answer 1

well think hwo scary it would be if the government (not only from your country but others) could just grop a few thousand nanobots into your air vents and gather any information they want about, maybe even kill you without you ever noticing.(well i mean you'd notice if you were dead... i guess)

Answer 2

Some nano particles can be toxic and due to their extremely small size they can easily seep into our blood vessels.
