2. Introduction  The environment is our home.  Nanotechnology is a term surrounding nanoscale science, engineering and technology (Sargent, 2011).  Nanotechnology is thought to bring significant social and economic benefits.  However, there are many researches who believe there are potential environmental, health and safety repercussions (Zhang, Misak, Dhanasekaran & Asmatulu, 2012).  Positive – To create environmentally friendly products.  Negative – Fear of the unknown

3. Positives  Nanomaterials have the potential to enhance the environment.  Nanomaterials are used to design cleaner industrial processes and to detect, prevent and remove pollutants.  Efficiency of lighting, heating, electrical storage capacity.  Reduced the amount of pollution from the consumption of energy (Sargent,2011)

4. Positives Nanotechnology has helped provide solutions for:  Pollution, energy consumptions and greenhouse gasses  The ability to identify and remove pollution.  Reduce the amount of waste  More efficient solar cells  Elimination of greenhouse gasses and other pollutants  Reduced amount of industrial plant usage (Rickerby & Morrison, 2012)

5. Examples Hydrogen car (“Nanoeverything, (Nanotechnology).” 2013) Cracking Cellulose (“Nanoeverything, (Nanotechnology).” 2013 ) Batteries (“Nanoeverything, (Nanotechnology).” 2013) Water(“Nanoeverything, (Nanotechnology).” 2013) Fuel Cell Water Treatment Cracking Cellulose Batteries

6.  Nanotechnology is a relatively new concept.  It is difficult to predict the damages.  Nanoparticles may be accumulated into the environment.  Nanoparticles may be ingested by fish.  It is vital know whether or not Nanomaterials are harmful or not. Fear of the Unknown (Wenning, 2013)

7. Conclusion  Even though the risks are evident in nanotechnology it has the potential to deliver important benefits.  Thankyou for listening.
