Nanotechnology has been an important outcome of the researches that has proved significant potential to solve various problems and improve life. As an on-going research, nanotechnology has resulted to notable impacts on life that exhibits in the fields of environmental conservation, economic development and health care sector. Despite the immeasurable ability to transform human life, some scientists warn that failure to impose strict regulation can allow misuse of the technology to lead to serious problems in the future. Impacts of Nanotechnology on Environmental Conservation Nanotechnology poses both positive and negative implications on the environment where life is abundant. To begin with, the technology has great potential of leading to improved techniques of environmental conservation such as efficient methods of purifying water and cleansing of air, reducing the use of pesticides and advent of green packaging (Karkare, 2010). Nanotechnology has seen a section of scientists focus on researches and tests to develop nanosensors that are capable of detecting, preventing and removing pollutants found in the air. Scientists have also proved that nanotechnology has the ability of guiding through the design of structures and machines capable of filtering smokes and industrial exhausts to ensure that only clean and safe air escapes into the atmosphere. For instance, scientists have used nanocomposites of silica and tatania to remove elementary mercury vapor as an alternative to conventional activated carbon injection (Karkare, 2010). In addition, scientists have used nanostructured silica to capture cadmium from an exhaust combustion environment. The additional environmental impact of nanotechnology relates to the ability of engineers to use the technology to purify water. This has been possible through the combined use of nanoporous ceramics and self assembled monolayers of functional groups to remove heavy metals from wastewaters. Scientists continually express fears that failure by the global community to establish appropriate laws to govern the development and use of nanotechnology can expose the world to unpredictable dangers. To begin with, scientists and companies that have invested in nanotechnology are competing to use the technology to produce self-replicating robots and organs. If uncontrolled, the competing parties can manipulate nanotechnology and produce creatures and features that are dangerous to life and hard to control (Patra, 2011). Another fear relates to the increasing application of nanotechnology in the field of war and military. Even though nanotechnology has enabled production of very destructive nuclear weapons that are good for defense of any country, the weapons may be subject to misuse. This can cause serious environmental effects to the whole if not a small part of the world (Karkare, 2010). Impacts of Nanotechnology on Technological Science As part of technology, structural engineers have grappled with the problem of structural failures due to weakening of steels when subjected to repeated conditions of stress. As demonstrated by Prashant, Nirangan, Shripal and Krishna (2013), continued research on nanotechnology has proved the possibility of producing strong steels that are capable of withstanding various degrees of stresses. An example of such advancement has manifested through the production of steel cables that have proved effective when used in the construction of bridges.
