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
