Essay / Nanotechnology and environment
Introduction: The world is going from bad to worse. As human beings, we waste everything we come across. We are the source of disasters on earth. The Earth is almost 4.6 billion years old and humans have lived on it for less than 12 million years. Yet in these few years, compared to the age of the Earth, we have destroyed more than 52% of its total forest. We have polluted its air. The water has become toxic. We lack raw materials. We cut almost everything in nature to feed our cravings. We kill animals. Very soon we will even run out of natural resources, like oil and gas. The world is not as perfect as we believe because we leave nothing for the next generation. We force poor children from poor areas to work in harsh and toxic conditions in order to sell what they earn to the rich. We are so greedy that we have started not caring about anything but making profit. These things are actually secretly supported by governments, but everyone shows at some point that they care about the Earth. What's so funny is that these companies celebrate Earth Day every year and destroy it every day. Humans are the originators of extensions of so many animals and plants. Say no to plagiarism.

Water, air, raw materials and natural resources will run out very soon. Everything will become toxic. Some Canadian companies have started selling clean air to Japan and China. Isn't it too early? Now the problem is how can we solve this problem? How can we save the world from destruction? There is always an answer to any question. The answer here is yes, we can! Nanotechnology is the tool through which we can solve all the problems mentioned above. Nanotechnology: “It is the study and application of extremely small things and can be used in all other scientific 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 titled "There's Plenty of Room at the Bottom" by physicist Richard Feynman at a meeting of the American Physical Society at the California Institute of Technology ( CalTech) on December 29, 1959, well before the term nanotechnology was used. In his discussion, Feynman described a procedure in which researchers would have the ability to monitor and control singular iotas and atoms. More than 10 years after the fact, in his research on ultra-precision machining, Professor Norio Taniguchi coined the term nanotechnology. It was not until 1981, with the improvement of the filtering and burrowing magnifying glass capable of “seeing” singular particles, that advanced nanotechnology began. The link between nanotechnology and the environment: Nanotechnology elements, procedures and applications are necessary to comprehensively contribute to the protection of the environment and the environment by saving raw materials, energy and water and reducing also substances harmful to the ozone layer and dangerous waste. The use of nanomaterials in this sense guarantees certain ecological advantages and impacts in terms of manageability. Note, however, that nanotechnologies today play a fairly secondary role in natural security, whether in studies orof concrete applications. Natural building organizations themselves place only limited emphasis on nanotechnology in their individual fields. Environmental benefits: rising prices of raw materials and energy, combined with the natural increasing attention paid to buyers, are causing an increase in available products that guarantee certain focal points for ecological safety and atmospheric. Nanomaterials exhibit physical characteristics and substance properties that make them fascinating for new and earth-pleasing objects. Cases incorporate the increased strength of materials against mechanical pressure or weather, thereby expanding the useful existence of an item; floor and water-safe coatings based on nanotechnology to reduce cleaning efforts; new protective materials to improve the vital productivity of structures; adding nanoparticles to a material to reduce weight and preserve vitality during transportation. In the area of substances, nanomaterials are connected due to their unusual synergistic properties with a specific end goal to support the vitality and effectiveness of active ingredients, and nanomaterials can supplant earth-hazardous synthetic compounds. in specific areas of use. High expectations are placed on nanomechanically streamlined elements and procedures for vitality generation and capacity; These areas are currently in the development phase and are expected to contribute essentially to ensuring the atmosphere and solving our vitality problems in the future. In most financially accessible “nano-client items,” ecological safety is not the essential objective. Neither materials containing nanosilver to combat sweat odor nor particularly stable golf clubs containing carbon nanotubes help protect the planet. Producers regularly guarantee such points of interest, usually without giving the relevant confirmation. Illustrations include surface coatings or self-cleaning materials with a one-time guarantee, which are advertised as reducing cleaning effort and thereby saving energy, water and cleaning operators. The focus is often on the sustainability of where nanotechnology will take us. Regardless, this normally reflects unconfirmed desires. Deciding on an object's real impacts on nature – both positive and negative – requires looking at the entire life cycle, from the creation of the raw material to its transfer to the end of the existing cycle. When in doubt, representations of ecological benefits neglect to take into account the measurement of resources and energy spent to deliver products.

Many batteries still contain important metals, for example, mercury, lead, cadmium and nickel, which can harm nature and pose a potential danger to human well-being when batteries are discarded in an unsafe manner. Not only are battery piles in landfills a natural problem, they are also a complete misuse of a potentially modest raw material. Specialists have discovered how to recover pure zinc oxide nanoparticles from used Zn-MnO2 soluble batteries.2-Nanomaterials for cleaning radioactive waste in water Researchers.
