Gray Goo

             Gray Goo is a hypothetical situation in which the world comes to destruction by the hands of menacing nanotechnology machines.

             These perpetrators, in this Armageddon scenario, consume all the resources on Earth while self-replicating faster than we can stop them.

            Although this fanciful end-world story seems implausible, there are applications of nanotechnology concerns about the environment. Nanotech pollution is in fact a real problem on our Earth and needs to be analyzed and solved.
