Science has made some inventions that have proved to be destructive for the humankind. These were invented for the betterment of the human beings but are rather proving to be a curse in following ways:. Pollution started with industrialization. Industries and vehicles contribute to major pollution. Inventions in the field of technology have led to an increase in pollution. It is due to this pollution that we are facing major problems like global warming and it has become a challenge for humanity. Many harmful and toxic gases are released into the environment by the industries.
These pollute the atmosphere. The air we take in is extremely polluted and causes various diseases. The waste these industries produce is often thrown in the rivers and other water resources leading to water pollution. The decline in aquatic species is the result of this pollution. Deadly and destructive weapons are again an invention of science.
Science has given high-tech weapons and warheads to the mankind. These weapons can cause mass killing and destruction at a distant place just by triggering a button.
The destructive applications of science like the nuclear bomb, Hydrogen Bomb, Poisonous gases, Missiles, Chemical warfare can finish the existence of any big city or country within seconds. The Nuclear power plant is a serious threat to the humankind and the environment, The Bhopal gas tragedy that took place in took lives of thousands and many were permanently disabled due to the poisonous gas leakage. With the invention of high-tech machinery, the work which used to be too time-consuming earlier hardly takes any time now. The invention might have eased our life but has also created unemployment.
Due to industrialization, less human force is required as all the major work is now being done by the machines. Science that was very beneficial in the early age of scientific inventions and discoveries has now turned out to be equally terrible for the mankind. It seems that the time is not too far when the whole human race will have to experience suffering due to the evils of science. Man must use scientific inventions wisely. Science contributes to an overall understanding of how and why things work.
It explains the reason behind the daily functioning of complex systems — from the human body to modern transportation. Students and children are able to use this knowledge to understand and learn new concepts, peruse new interests and make well-informed decisions. It also provides tactical and visible proof of many facts we read in books or see on T. This helps in raising the understanding and helps children to keep hold of the information.
Science knows no boundaries as it is a universal subject.
After years of active and persistent efforts, science claimed to be a part of the school curriculum and got recognized. Science has proved indispensable for the existence of man and has revolutionized human life. The tempo of our lives has also been quickened. A new social and political outlook has been given to the man altogether. Hence, the study of science has become a necessity in this age and without learning the modern science a man is like a lame individual with no sense of the modern era.
Here is why it is important to learn the wonders of science at the school level:. The study of science and technology proceed as an everlasting urge to obtain knowledge. The more we know of the secrets of nature, the more we understand how much remains unidentified. Now scientists talk about the wonder of nature with an excitement of emotion.
We are learning as much of the secrets of the molecular cells in a living organism as of the atoms in space. So a modern syllabus of studies must comprise the study of science and technology because the modern man needs a scientific mind in approaching the problems of life. Science is everywhere from an ordinary pen to a printing machine, from a paper airplane to space shuttle. Science is an integral part of our daily life.
Science has made our life easy and comfortable with its innovations. Science has changed every field of life. Impossible things have become possible. Thousands of things we use in our daily life are the gift of science. Here is a look at some of these:. Science has given us various gifts but it can also be used to harm human beings.
It has given us rifles as well as bullet-proof jackets. It depends on us as to how we use science — for the welfare of humanity or for the destruction of humanity. We must use science for enhancing our lifestyle and spreading smiles and not for giving tears to someone.
Stop the violence and spread happiness everywhere. We humans observe our surroundings or incidents and document our inferences, in form of facts and figures. This further leads to some new explorations and logical conclusions, which is termed as science. Science is in a regular process of development and exploration, through human intervention.
Without wheels a nation will stand still, stalling its growth. Could you imagine going to office or school without using any wheel on anything, in some way or the other, for that matter. Of course not! For instance, scientists have been using electrodes placed on the head to run a mild electrical current through the brain, a procedure known as transcranial direct-current stimulation tDCS. Research shows that tDCS, which is painless, may increase brain plasticity, making it easier for neurons to fire. This, in turn, improves cognition, making it easier for test subjects to learn and retain things, from new languages to mathematics.
Already there is talk of implanting a tDCS pacemaker-like device in the brain so recipients do not need to wear electrodes. According to many futurists, tDCS is akin to an early steam train or maybe even a horse-drawn carriage before the coming of jumbo jets and rockets. If, as some scientists predict, full brain-machine interface comes to pass, people may soon have chips implanted in their brains, giving them direct access to digital information.
The next step might be machines that augment various brain functions. Once scientists complete a detailed map of exactly what different parts of our brain do, they will theoretically be able to augment each function zone by placing tiny computers in these places. Augments placed in our frontal lobe could, theoretically, make us more creative, give us more or less empathy or make us better at mathematics or languages.
For data on whether Americans say they would want to use potential technology that involved a brain-chip implant to improve cognitive abilities, see the accompanying survey, see U. Genetic engineering also offers promising possibilities, although there are possible obstacles as well. Scientists have already identified certain areas in human DNA that seem to control our cognitive functions. In spite of this optimism, some scientists maintain that it will probably be a long time before we can bioengineer a substantially smarter person.
For one thing, it is unlikely there are just a few genes or even a few dozen genes that regulate intelligence. Indeed, intelligence may be dependent on the subtle dance of thousands of genes, which makes bioengineering a genius much harder. Even the optimistic Sandberg says that enhancing the brain could prove more difficult than some might imagine because changing biological systems can often have unforeseen impacts.
But many futurists say enhancement technologies will likely be used to transform the whole body, not just one part of it. This includes efforts to manufacture synthetic blood, which to this point have been focused on therapeutic goals. But as with CRISPR and gene editing, artificial blood could ultimately be used as part of a broader effort at human enhancement. It could be engineered to clot much faster than natural human blood, for instance, preventing people from bleeding to death. Synthetic white blood cells also could potentially be programmed.
These microscopic particles are a far cry from synthetic blood, since they would be used once and for very specific tasks — such as delivering small doses of chemotherapy directly to cancer cells. However, nanoparticles could be precursors to microscopic machines that could potentially do a variety of tasks for a much longer period of time, ultimately replacing our blood. According to Sandberg and others, substantially more oxygen in the blood could have many uses beyond the obvious benefits for athletes.
For data on whether Americans say they would want to use potential synthetic blood substitutes to improve their own physical abilities, see the accompanying survey, U. So where is all of this new and powerful technology taking humanity? The answer depends on who you ask. Having more energy or even more intelligence or stamina is not the end point of the enhancement project, many transhumanists say. Some futurists, such as Kurzweil, talk about the use of machines not only to dramatically increase physical and cognitive abilities but to fundamentally change the trajectory of human life and experience.
Kurzweil is not the only one who thinks we are on the cusp of an era when human beings will be able to direct their own evolution. Based on our past experience, we know that most of these things are unlikely to happen in the next 30 or 40 years. In the future, Vita-More predicts, our bodies will be radically changed by biological and machine-based enhancements, but our fundamental sensorial life — that part of us that touches, hears and sees the world — will remain intact.
However, she also envisions something she calls a whole-body prosthetic, which, along with our uploaded consciousness, will act as a backup or copy of us in case we die. Others, like Boston University bioethicist George Annas, believe Kurzweil is wrong about technological development and say talk of exotic enhancement is largely hype. He points to many confident predictions in the last 30 or 40 years that turned out to be unfounded. Currently, only a small number of patients have artificial hearts and the devices are used as a temporary bridge , to keep patients alive until a human heart can be found for transplant.
Faggella, the futurist who founded TechEmergence, sees a dramatically different future and thinks the real push will be about, in essence, expanding our consciousness, both literally and figuratively. The desire to be stronger and smarter, Faggella says, will quickly give way to a quest for a new kind of happiness and fulfillment.
What exactly does that mean? Enhancing our brains will be about making us capable. T o some degree, the ideas and concepts behind human enhancement can be traced to biologist and author Julian Huxley. The novel is set in a future where, thanks to science, virtually no one knows violence or want. Although there is an abundance of material comforts in this fictional world, the things that people traditionally believe best define our humanity and make life worth living — love, close relationships, joy — have largely been eliminated.
In contrast with his brother Aldous, Julian Huxley was a scientific optimist who believed that new technologies would offer people amazing opportunities for self-improvement and growth, including the ability to direct our evolution as a species. John Vianney Theological Seminary in Denver.

For some thinkers, concerns about inequality go much further than merely widening the existing gap between rich and poor. They believe that radical enhancement will threaten the very social compact that underpins liberal democracies in the United States and elsewhere. Brugger of St. John Vianney Theological Seminary agrees.
Supporters of human enhancement say the goal is not to create a race of superhumans but to use technological tools to improve humanity and the human condition. Indeed, they say, it is an extension of what humans have been doing for millennia: using technology to make life better. A good example, Vita-More says, is cognitive enhancement. Those who support human enhancement also deny that these developments will make social inequalities dramatically worse. New technologies are often socially disruptive and can have a negative impact on certain vulnerable populations, they say. But the problem of inequality is essentially, and will remain, a political one.
Hughes, Bostrom and others also dispute the idea put forth by Fukuyama and Brugger that enhancement could displace the sense of common humanity that has undergirded the democratic social contract for centuries. First, they point out that the history of the modern West has been one of an ever-expanding definition of full citizenship. In addition, supporters of enhancement say, the notion that there will be a distinctive species of enhanced individuals who will try to enslave their unenhanced brothers and sisters might make for good science fiction, but it is not likely to happen. Instead, they say, there will be many different types of people, with different types of enhancements.
Finally, transhumanists and other supporters say, history shows that as people gain more control over their lives, they become more empathetic, not less. Happiness is found in marriages, in families, in neighborhoods … None of these are promised by enhancement.http://ofprobol.sdb.bo/wp-content/austin/3131-citas-en.php
Happiness - Wikipedia
Critics of enhancement question whether people really will be happier if enhancement projects are allowed to come to fruition. According to these critics, philosophers have long held that true happiness does not come from enhanced physical prowess or dramatically longer life, but from good character and virtuous living. But supporters contend that life still will be meaningful and challenging in a world where enhancement is widespread. Furthermore, an enhanced life will still contain challenges and limits, just different ones, says Ronald Cole-Turner, a professor of theology and ethics at Pittsburgh Theological Seminary, which is associated with the Presbyterian Church U.
Because human enhancement is still largely an issue for the future, it has not yet attracted a lot of attention in American religious communities. There is, for instance, no official teaching or statement on human enhancement or transhumanism that has come directly from any of the major churches or religious groups in the United States. According to many theologians, the idea that human beings in certain ways mirror God make some, but not all, religious denominations within this broad set of connected traditions wary of using new technologies to enhance or change people, rather than heal or restore them.
Andrews in Scotland. Catholics actively support medical and technological advances that can restore someone to health, says Brugger. Concerns about crossing that line already have been expressed by Catholic-affiliated organizations.

Conservative evangelical Protestant churches also are likely to be wary of treatments or technologies that enhance, rather than heal, people, says Daly of Urbana Theological Seminary. Courage, fidelity, fortitude, generosity, hope, moderation, perseverance, are all cultivated in response to limitations of circumstance and nature.
Opposition also would be likely from the Church of Jesus Christ of Latter-day Saints, which teaches that the body is sacred and thus must not be altered. The Hindu tradition probably would approach human enhancement as a potentially dangerous development as well, although for different reasons than Christian churches, says Deepak Sarma, a professor of South Asian religions and philosophy at Case Western Reserve University in Cleveland.
Viewed in this light, Sarma says, Hindus could see enhancement as keeping someone from cleansing themselves of these misdeeds from their past lives. In Islam, according to Sherine Hamdy, an associate professor of anthropology at Brown University, human enhancement would be viewed with concern by some scholars and leaders and embraced by others. Other churches and religious traditions, however, probably would not be opposed or even divided on the issue, scholars say.
For instance, mainline Protestant denominations, such as the Presbyterian, Episcopalian or Methodist churches, are unlikely to attempt to prevent their members from taking advantage of new enhancements, says Cole-Turner of Pittsburgh Theological Seminary, which serves a student body made up mostly of mainline Protestants. According to Lutheran theologian Peters, many mainline churches will view enhancement positively because they will see aspects of it as attempts to improve human well-being and alleviate suffering.
Similarly, Buddhists would largely accept and even embrace human enhancement because it could help them become better Buddhists, says Hughes, who is an advocate for transhumanism as well as a Buddhist and a former Buddhist monk. These changes, if they occur, will upend some social norms and possibly religious norms as well. And they will force churches and many other institutions both religious and secular to adjust to a new reality.
For the first time in human history, the biggest material changes in our society may not be occurring outside of ourselves, in the fields, factories and universities that have shaped human civilization, but inside our bodies — in our brains and muscles and arteries, and even in our DNA.
