Environmental Issues
Only about 10 percent of the cell phones used in the United States are recycled.
• Recycling just one cell phone saves enough energy to power a laptop for 44 hours.
• 130 million cell phones are tossed aside annually in the United States this is enough energy to power more than 24,000 homes for a year.
• Recycling one million cell phones also saves enough energy to provide electricity to 185 U.S. households for a year.
• Cell phones, PDAs and other electronic devices also contain hazardous materials such as lead, mercury, cadmium, arsenic and brominated flame retardants. Many of those materials can be recycled and reused; none of them should go into landfills where they can contaminate air, soil and groundwater.

E-Commerce
E-Commerce
Online retail sales account for 11 percent of total sales in the United States and 7 percent of worldwide spending. US sales are expected to top $156 billion this year, excluding revenues associated with traveling.
More consumer dollars are spent online because of comparison shopping and convenience.

Social Media Revolution
http://www.youtube.com/watch?v=lFZ0z5Fm-Ng&feature=related
Change your lifestyle…
…even your job.
You get lots of followers
Much of the night networking on a computer might be bad for your body and your brain.
Are you suffering from social networking?

The greater use of the internet
declines in communication between family
members in the house
declines in the size of their social circle
increase in their levels
of depression
and loneliness
Social Networking
The time we spend socializing electronically separates us from our physical networks. There's a wide world out there with no Twitter, Facebook, MySpace and email even.

E-reader
Saving Space
You can have hundreds of books in a device smaller than a moleskin journal.
Saving green (money)
Costs of e-books are much cheaper than buying the hardcovers or paperbacks off the bookstore shelves.
Less gas
Downloading an e-book takes just seconds and requires no transportation.
It requires no use of gas.
Carbon Emission
E-readers take a certain amount of carbon emission to produce.
Truth: “E-books are having effectively no positive impact on the environment”. If publishers continue to produce large numbers of books, e-readers will prove useless to the environment.
Will e-books replace ink and paper?
Nanotechnology
What is Nanotechnology?
Nanotechnology is the science of building structures at a subatomic level. The prefix nano refers to the scale of these constructions. A nanometer is
one-billionth of a meter. To put that scale in context, the comparative size of a nanometer to a meter is the same as that of a marble to the size of the earth!

History of Nanotechnology
In 1959, Richard Feynman became the first individual to give a lecture about the concepts involved in nanotechnology. He gave the talk at the American Physical Society at Caltech. The first experimental proof that individual atoms could be manipulated was obtained by IBM scientists back in 1989, when they used a scanning tunneling microscope to precisely position 35 xenon atoms on a nickel surface to spell out the corporate logo "IBM."
Some Benefits of Nanotechnology
Nanomedicine
Cheap and clean energy
Clean Water
Pollution Reduction and Environmental Progress
Improved Materials and New Products
Nanomedicine
Nanomedicine is focused on diagnosing and treating diseases and creating new drug delivery techniques with fewer side effects. Some examples of nanomedicine are...
• Detection - Nanotech-enabled sensors may be able to “smell” cancer. • Imaging - Gold nanoparticles can be used to detect disease.• Regeneration - Nanogels can spur the regrowth of brain and nerve cells.
Cheap and Clean Energy
The difficulty of meeting the world’s energy demand is compounded by the growing need to protect our environment. Many scientists are looking into way to develop clean, affordable and renewable energy sources.
Solar panels Batteries Fuel cells for alternative transportation
Clean Water
Clean water is a precious natural resource and a basic necessity. While the worldwide supply of potable water is limited, the demand continues to increase. Nanotechnology could help meet the need for affordable clean water through inexpensive water purification, as well as rapid, low cost detection of impurities.
Pollution Reduction and Environmental Progress
There are many eco-friendly possibilities for nanotechnology, including
Lighter cars and machinery that requires less fuel Alternative fuel and energy sources Materials that detect and clean up environmental contaminants
Improved Materials and New Products
The very structure of materials can be improved through nanotechnology, by developing nanomaterials that are stronger, lighter, more durable or better conductors, among other traits.
Adding nanoparticles to plastics can make them stronger, lighter and more durable. Nanoparticles are currently used in baseball bats and tennis rackets, but someday may also be used in bulletproof vests and light, fuel efficient vehicles.
Different nanoscale materials can be used in thin films to make them water-repellent, anti-reflective, self-cleaning, ultraviolet or infrared-resistant, antifog, anti-microbial, scratch-resistant, or electrically conductive.
Nanofilms are used now on eyeglasses, computer displays, and cameras to protect or treat the surfaces. Nanoscale transistors may someday lead to computers that are faster, more powerful and more energy efficient than those used today.
Some Risks of Nanotechnology
NanotoxicologyNano Pollution
Nanotoxicology
The extremely small size of nanomaterials also means that they are much more readily taken up by the human body than larger sized particles. How these nanoparticles behave inside the body is one of the issues that needs to be resolved. The behavior of nanoparticles is a function of their size, shape and surface reactivity with the surrounding tissue.
Nanopollution
Nanopollution is a generic name for all waste generated by nanodevices or during the nanomaterials manufacturing process. This kind of waste may be very dangerous because of its size. It can float in the air and might easily penetrate animal and plant cells causing unknown effects.
Most human made nanoparticles do not appear in
nature, so living organisms may not have appropriate means to deal with nonwaste. It is probably one great challenge to nanotechnology: how to deal with its nanopollutants and nanowaste.
Cloning
Cloning
In biological terms, cloning is the process of creating an organism (plant or animal) that is an exact genetic copy of another through nonsexual means.
Cloning
Before your thoughts about cloning begin to turn negative, think about this… nature has been cloning organisms for billions of years!
For example, when a strawberry plant sends out a runner (a form of modified stem called a stolon), a new plant grows where the runner takes root. That new plant is a clone! Similar cloning occurs in grass, potatoes and onions.
Cloning
Perhaps the most well known example of cloning is Dolly, a sheep from Scotland that became the first cloned mammal in 1996. Dolly was the only sheep out of 277 attempts that made it to a live birth. She gave birth to four lambs before she passed away in 2003.
Cloning
Although a handful of people across the world have announced that they have cloned a baby, no one has ever produced any conclusive proof that a cloned baby exists.
Oh My! I’ve been cloned!
Some Benefits of Cloning
More predictable and reliable crop yields, meaning more food for more people.
Disease and pesticide resistant plants.
Significantly lower growing costs.
Production of "super" fruits and vegetables of superior nutritional quality could result in decreases in nutritional deficiencies around the world and make for a healthier population overall.
Some Benefits of Cloning
Genetically modified cells and organs from animals can be transplanted into humans to treat disease and injury.
Many human diseases such as Parkinson's, Alzheimer's, MS, diabetes and cancer could be treated using genetically altered cells from other humans (embryonic, fetal and adult stem cells).
People who can't have children in the traditional way can have children of their own.
Potential Uses of Stem Cells
Some Risks of Cloning
By "playing God" we may disrupt the natural evolutionary process (survival of the fittest) in the plant world.
Cloning is a highly inefficient, experimental, and unpredictable technology that presents serious threats to both animal and human health and welfare.

“Due to the controversy over cloning our first human, we have decided to choose a subject that would have little to no impact on society around him.”
