The world is going from bad to worse. We as human being are wasting everything we face. We are the source of disasters in the earth. The Earth is almost 4.6 billion years old, and humans have been living on it for less than 12 million years. Still, in these few years comparing them to the age of the earth, we have destroyed more than 52% of its total forest. We have polluted its air. The water became toxic. We are running out of raw materials. We are cutting almost everything in nature to feed our desires. We are killing the animals. Very soon we will even run out of natural resources, such as oil and gas. The world is not as perfect as we believe because we are not leaving single thing for the next generation. We are forcing poor kids in poor areas to work under tough and toxic conditions in order to sell what they make to the rich people. We are so greedy to the point where we started not to care about anything but to make profit. These stuffs are actually supported secretly by the governments, but everyone at a point shows that they care about the Earth. What is so funny is that these companies are celebrating Earth day every year and destroying it every day. Humans are the reason behind the extensions of so many animals and plants.
Humans are the reason for the new diseases that we are facing every day. Water, air, raw materials, and natural resources are going to be missed very soon. Everything is going to be toxic. Some companies in Canada have started to sell clean air to Japan and China. Is not that too early? Now the thing is that how can we solve that problem? How can we rescue the world from destruction? There is always an answer to any question. The answer here is yes, we can! Nanotechnology is the tool in which we can solve all of the mention problems above. Nanotechnology: “It is the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering.” How did it start? The thoughts and ideas driving nanoscience and nanotechnology began with a discussion entitled “There’s Plenty of Room at the Bottom” by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, well before the term nanotechnology was utilized. In his discussion, Feynman depicted a procedure in which researchers would have the capacity to control and control singular iotas and atoms. Over 10 years after the fact, in his investigations of ultraprecision machining, Professor Norio Taniguchi authored the term nanotechnology. It wasn’t until the point when 1981, with the improvement of the filtering burrowing magnifying lens that could “see” singular particles, that cutting edge nanotechnology started.
The connection between nanotechnology and the environment: Nanotechnological items, procedures and applications are required to contribute altogether to ecological and atmosphere assurance by sparing crude materials, vitality and water and additionally by lessening ozone harming substances and unsafe squanders. Utilizing nanomaterials along these lines guarantees certain ecological advantages and manageability impacts. Note, in any case, that nanotechnology at present assumes a fairly subordinate part in natural security, regardless of whether it be in look into or in down to earth applications. Natural building organizations themselves join just restricted significance to nanotechnology in their individual fields. The environmental benefits: Rising costs for crude materials and vitality, combined with the expanding natural attention to purchasers, are in charge of a surge of items available that guarantee certain focal points for ecological and atmosphere security. Nanomaterials show extraordinary physical and substance properties that make them fascinating for a novel, earth agreeable items. Cases incorporate the expanded solidness of materials against mechanical pressure or weathering, expanding the helpful existence of an item; nanotechnology-based soil and water-safe coatings to decrease cleaning endeavors; novel protection materials to enhance the vitality productivity of structures; adding nanoparticles to a material to diminish weight and spare vitality amid transport.
In the substance business area, nanomaterials are connected in view of their uncommon synergist properties with a specific end goal to support vitality and asset effectiveness, and nanomaterials can supplant earth dangerous synthetic compounds in specific fields of utilization. High expectations are being put in nanomechanically streamlined items and procedures for vitality generation and capacity; these areas of now in the improvement stage and are slated to contribute essentially to atmosphere insurance and taking care of our vitality issues later on. In most financially accessible “nano-customer items”, ecological security isn’t the essential objective. Neither materials with nanosilver to battle sweat scent, nor particularly stable golf clubs with carbon nanotubes, help ensure the earth. Producers regularly guarantee such points of interest, normally without giving the pertinent confirmation. Illustrations incorporate self-cleaning surface coatings or materials with spot assurance, with are advertised as diminishing the cleaning exertion and along these lines sparing vitality, water and cleaning operators.
Accentuation is frequently put on the supportable capability of where nanotechnology will take us. In any case, this normally reflects unconfirmed desires. Deciding the genuine impacts of an item on nature – both positive and negative – requires looking at the whole lifecycle from the creation of the crude material to transfer toward the finish of the existing cycle. When in doubt, the portrayals of ecological advantages neglect to consider the measure of assets and vitality expended in delivering the items. (read more: “Nanotechnology and the earth – Potential advantages and manageability impacts”) Examples of nanotechnology and its effects on the environment:
1-Nanotechnology could make battery reusing financially alluring Numerous batteries still contain substantial metals, for example, mercury, lead, cadmium, and nickel, which can taint nature and represent a potential danger to human wellbeing when batteries are despicably discarded. Not exclusively do the heaps of batteries in landfills represent a natural issue, they additionally are a total misuse of a potential and modest crude material. Specialists have figured out how to recoup unadulterated zinc oxide nanoparticles from spent Zn-MnO2 batteries soluble batteries.
2-Nanomaterials for radioactive waste tidy up in water Researchers are taking a shot at nanotechnology answer for radioactive waste cleanup, particularly the utilization of titanate nanofibers as sponges for the expulsion of radioactive particles from water. Analysts have additionally detailed that the interesting auxiliary properties of titanate nanotubes and nanofibers make them prevalent materials for expulsion of radioactive cesium and iodine particles in water.
3-Nanotechnology-based answers for oil slicks Traditional tidy up strategies are not satisfactory to take care of the issue of gigantic oil slicks. As of late, nanotechnology has risen as a potential wellspring of novel answers for a considerable lot of the world’s remarkable issues. In spite of the fact that the utilization of nanotechnology for oil slick cleanup is still in its incipient stage, it offers incredible guarantee for what’s to come. Over the most recent few years, there has been especially developing interest worldwide in investigating methods for finding reasonable answers for tidy up oil slicks through utilization of nanomaterials.
4-Water application The potential effect territories for nanotechnology in water applications are partitioned into three classifications – treatment and remediation, detecting and recognition, and contamination avoidance – (read more: “Nanotechnology and water treatment”) and the change of desalination advancements is one key region thereof. Nanotechnology-based water decontamination gadgets can possibly change the field of desalination, for example by utilizing the particle fixation polarization marvel (see: “Nanotechnology makes convenient seawater desalination gadget conceivable”). 5-Hydrogen creation from daylight – fake photosynthesis Organizations creating hydrogen-controlled innovations get a kick out of the chance to envelop themselves by the green sparkle of ecologically amicable innovation that will spare the planet. While hydrogen fuel to be sure is a perfect vitality bearer, the wellspring of that hydrogen regularly is more or less filthy. The issue is that you can’t burrow a well to tap hydrogen, however hydrogen must be delivered, and that should be possible utilizing an assortment of assets. The dirtiest strategy – in any event until the point when profoundly proficient carbon catch and sequestration innovations are created – is the gasification of coal (read more: “Nanotechnology could tidy up the hydrogen auto’s skeleton in the closet”).
The cleanest by a long shot would be sustainable power source electrolysis: utilizing sustainable power source advances, for example, wind, sun oriented, geo-and aqueous capacity to part water into hydrogen and oxygen. Fake photosynthesis, utilizing sun powered vitality to part water creating hydrogen and oxygen, can offer a perfect and versatile wellspring of vitality supply as sturdy as the daylight. It takes around 2.5 volts to separate a solitary water atom into oxygen alongside contrarily charged electrons and emphatically charged protons. It is the extraction and partition of these oppositely charged electrons and protons from water atoms that gives the electric power. Chipping away at the nanoscale, scientists have demonstrated that an economical and ecologically benevolent inorganic light gathering nanocrystal cluster can be joined with an ease electrocatalyst that contains plenteous components to create a modest and stable framework for photoelectrochemical hydrogen generation. In conclusion: We have to save the world. We have to leave things for the next generation.
We want the generation after us to have a better life. We are running out of raw materials, water, air, and natural resources. Almost everything is toxic. New diseases appear every single day. Nanotechnology is the science in which companies should focus on. We do not want to buy clear air from Ice land in the future. We do not want to witness the extension of other animals and plants. We want to have our life sufficiently without harming other creatures.
