Man and his Environment-
Nanotechnology
The good, the bad, and the future
The one example of development in science and technology that man brings about:
Using nanotechnology to create
Nanobots
Description:
Start from a few molecules, atoms
Built from base to top
Programming enables it to do anything
Description: Nanobots-Might Cure Cancer
Powered by charged particles in our blood
Deliver correct dosage of medicine at the
right time
Tracked via cameras, ultrasound signals
and MRI machine
Tested out successfully-leaves good cells
alone, works with other treatments
Description: Immortality
Replace biological blood
Heal wounds immediately
Regrow limbs
Access backed-up memories &
personalities
Changes human nature
Positive Impacts:
Less chance of mistakes made
-Less traumatic for patients
-Faster recovery for patients
-More accurate and faster operations
Negative Impacts:
Humans:
Toxic nanoparticles cause lung injury
Lab mice:
Breathe in nano-titanium dioxide
Die of DNA and chromosome damage
Negative Impacts:
Nanobots-Small:
Cannot check
Malfunctioning
Prevent escaping:
Require small, special hospital rooms
Patients cannot wander freely
Long, expensive hospital stays
Why should man bear responsibility towards the environment from which he draws his resources?
Negatively affect Nature:Toxic nanoparticles escape and harm living
thingsCause animal mutationCause imbalance in nature
Be responsible:Does not deplete scarce resources
Is technology good or bad?Good, may be abused:
Nanobots might clot arteries instead of
clearing them
People might act irresponsibly, thinking
nanobots will cure.
Handle with care
