Noise pollution is a very special type of pollution.
(Definition:) It is known to be the exposure to some high sound levels that may lead to adverse effects in humans or other living organisms. (Causes:) Noise becomes harmful when it exceeds 75 decibels (dB), such as the sound at a busy residential road. Noise is painful when above 120 dB, such as the sound of a jet taking off. (Effects:) Noise pollution affects not only the hearing but also the nervous system. It can make us deaf or have high blood pressure, nervousness, hearing loss, and sleep disturbances.

1. Write about a type of pollution in your area số 1Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.

Pollution has become a major environmental issue as it has created lots of health hazards to the people and animals of any age group. In the recent years the rate of pollution is increasing very sharply because of the industrialized waste material mixing out directly into the soil, air and water. However, in our country full attention is not getting paid to control it. It needs to be tackle seriously otherwise our future generations would suffer a lot.
Pollution is classified into many categories according to the natural resources getting affected such as air pollution, soil pollution, water pollution, noise pollution, etc. Rate of pollution is increasing due to the selfishness of the human being to earn more money and to fulfill some unnecessary wishes. In the modern era where technological advancement is given more priority by the people, everyone has forgotten the real discipline of life.
Continuous and unnecessary cutting down of the forests, urbanization and large production through industrialization has involved as a huge causes of the pollution. Harmful and poisonous wastes created from such activities causes irreversible changes to the soil, air and water which ultimately push lives towards pain. This big social issue needs a public level social awareness programme to destroy by its root to get complete relief.
Pollution is the mixing of some harmful or poisonous materials into the natural resources available on the earth. It affects the ordinary living of the living things on this planet by disturbing the natural life cycle. Pollution can be of many types like noise pollution, air pollution, soil pollution, water pollution, etc. Air pollution is increasing day by day because of the growing number of automobiles, release of poisonous gases, smoke from industrial companies, finely dissolved solids, liquid aerosols, etc in the atmosphere. The air we breathe every moment causes several lungs disorders.
In this way soil and water pollution is also cause by the mixing up of the sewage water (having germs, viruses, harmful chemicals, etc) in drinking water, some dangerous agrochemicals such as pesticides, fungicides, herbicides, organic compounds like ether, benzene, some radioactive materials including radium and thorium, solid wastes (industrial ashes, rubbish, garbage), etc. We need to follow all the control measures implemented by the government to check its harmful effects.
Hal Varian, chief economist at Google, has a simple way to predict the future. The future is simply what rich people have today. The rich have chauffeurs. In the future, we will have driverless cars that chauffeur us all around. The rich have private bankers. In the future, we will all have robo-bankers.
One thing that we imagine that the rich have today are lives of leisure. So will our future be one in which we too have lives of leisure, and the machines are taking the sweat? We will be able to spend our time on more important things than simply feeding and housing ourselves?
Let’s turn to another chief economist. Andy Haldane is chief economist at the Bank of England. In November 2015, he predicted that 15 million jobs in the UK, roughly half of all jobs, were under threat from automation. You’d hope he knew what he was talking about.
AdvertisementAnd he’s not the only one making dire predictions. Politicians. Bankers. Industrialists. They’re all saying a similar thing.
“We need urgently to face the challenge of automation, robotics that could make so much of contemporary work redundant”, Jeremy Corbyn at the Labour Party Conference in September 2017.
“World Bank data has predicted that the proportion of jobs threatened by automation in India is 69 percent, 77 percent in China and as high as 85 percent in Ethiopia”, according to World Bank president Jim Yong Kim in 2016.
It really does sound like we might be facing the end of work as we know it.
Many of these fears can be traced back to a 2013 study from the University of Oxford. This made a much quoted prediction that 47% of jobs in the US were under threat of automation in the next two decades. Other more recent and detailed studies have made similar dramatic predictions.
Now, there’s a lot to criticize in the Oxford study. From a technical perspective, some of report’s predictions are clearly wrong. The report gives a 94% probability that bicycle repair person will be automated in the next two decades. And, as someone trying to build that future, I can reassure any bicycle repair person that there is zero chance that we will automate even small parts of your job anytime soon. The truth of the matter is no one has any real idea of the number of jobs at risk.
Even if we have as many as 47% of jobs automated, this won’t translate into 47% unemployment. One reason is that we might just work a shorter week. That was the case in the Industrial Revolution. Before the Industrial Revolution, many worked 60 hours per week. After the Industrial Revolution, work reduced to around 40 hours per week. The same could happen with the unfolding AI Revolution.
Another reason that 47% automation won’t translate into 47% unemployment is that all technologies create new jobs as well as destroy them. That’s been the case in the past, and we have no reason to suppose that it won’t be the case in the future. There is, however, no fundamental law of economics that requires the same number of jobs to be created as destroyed. In the past, more jobs were created than destroyed but it doesn’t have to be so in the future.
In the Industrial Revolution, machines took over many of the physical tasks we used to do. But we humans were still left with all the cognitive tasks. This time, as machines start to take on many of the cognitive tasks too, there’s the worrying question: what is left for us humans?
Some of my colleagues suggest there will be plenty of new jobs like robot repair person. I am entirely unconvinced by such claims. The thousands of people who used to paint and weld in most of our car factories got replaced by only a couple of robot repair people.
No, the new jobs will have to be doing jobs where either humans excel or where we choose not to have machines. But here’s the contradiction. In fifty to hundred years time, machines will be super-human. So it’s hard to imagine of any job where humans will remain better than the machines. This means the only jobs left will be those where we prefer humans to do them.
The AI Revolution then will be about rediscovering the things that make us human. Technically, machines will have become amazing artists. They will be able to write music to rival Bach, and paintings to match Picasso. But we’ll still prefer works produced by human artists.
These works will speak to the human experience. We will appreciate a human artist who speaks about love because we have this in common. No machine will truly experience love like we do.
As well as the artistic, there will be a re-appreciation of the artisan. Indeed, we see the beginnings of this already in hipster culture. We will appreciate more and more those things made by the human hand. Mass-produced goods made by machine will become cheap. But items made by hand will be rare and increasingly valuable.
Finally as social animals, we will also increasingly appreciate and value social interactions with other humans. So the most important human traits will be our social and emotional intelligence, as well as our artistic and artisan skills. The irony is that our technological future will not be about technology but all about our humanity.
