Technology and Society of the Future English notes class 12th federal board Chapter #13

Q 1. When did the modern science and technology begin to make progress?

Allah Almighty has blessed man with the supremacy of brain to ponder, analyze and selects the right path for him. Since the beginning of this world, man is generating and producing things which are practical for him. Modern science and technology began to make progress in the seventeenth century but before that people have created the spectacular wonders of the world like the pyramids of Egypt without using any of the latest engineering tools or architectural plots. After the seventeenth century, the progress in the field of modern science and technology is not only evident but quite impressive too. It was the era that should be marked as a milestone in changing the lifestyle of the masses all over the world due to the amazing inventions and remarkable discoveries.

Q 2. How have modern science and technology brought a revolution in the life of human beings?

The era we are living in is the period dedicated to the awe-inspiring work done in the field of science and technology, where at every nook and corner of our surrounding we come across a number of scientific discoveries and innovations moving around or static but still have a strong impact on our lives. Modern science and technology have brought about a significant revolution in the life of human beings with the discoveries in the field of medicine, agriculture, industry, electrical appliances, transportation, information technology, and communication. This revolution not only changed the lifestyle of people but helped a lot in saving the lives of mankind to a great extent.

Q 3. How has science enabled man to modify his environment?

The relationship between man and his environment is of utmost importance. The environment is a system withholding a number of organisms that depend on it for their survival and well-being. Man is the only individual to be able to build and use equipment that can modify the landscape in a very short period of time. Nature would take thousands of years to produce the same changes as the ones produced by man. Human activities in the environment strictly depend on the type of economic activity and how society is organized. In some cases, human activities aim at recovering environmental disruption. As a consequence, man can be considered as an important landscape-modifying agent. Science has enabled man to modify his environment to suit his needs and requirements necessary for his continued existence. This is the prime reason why crop farming under greenhouses is 96% effective with abnormal profits to the farmer in the long run. Before the advent of modern science, people used to believe in supernatural forces that were responsible for bringing about both positive and negative changes in their environment and lifestyle. But then with the birth of science and technology, human beings became more confident to control and modify their environmental conditions. Now, they do not consider the weather conditions as the result of supernatural, good or evil forces but they have the potential to contemplate independently, logically and scientifically to overcome the environmental hazards.

Q 4. What did people believe in before the establishment of science and technology?

The establishment of science and technology not only made the lives of the masses comfortable but has significantly changed the school of thought of millions too. Before the advent of science and technology, people had a strong belief in superstitions and in certain supernatural forces that they thought are responsible for controlling their future. Magic and fortune telling were those professions that were worthy of respect and fame as people consider them accurate and precise in predicting their future happenings.

Q 5. How do people think in the era of technology and science?

Allah Almighty has blessed man with the power to think and make decisions as other creatures of this world are devoid of this humane eminence. Before the emergence of science and technology, people used to believe in superstitions and supernatural forces more but the era of science and technology awaken the inborn ability of mankind to think rationally, independently and more importantly scientifically too. Due to this optimistic change in the school of thought of man, the windows of ignorance were forced to shut off and the doors of awareness, enlightenment, and learning are unlocked to welcome mankind with open arms to unleash the hidden treasures of nature and utilize it to the maximum for the betterment and welfare of humanity.

Q 6. Why did millions of people die in the great plague that started in 542 AD?

Q 8. Has smallpox been eradicated once for all from the world?

Some of the major diseases that must be held responsible for taking souls of millions from the world include smallpox, plague, typhoid, cholera, and malaria. Smallpox was not eradicated once for all from the world, it took years to eliminate it and saved the lives of the masses. It was just made possible with the discovery of various medicines and revolution in surgery.

Q 9. How people travelled from one place to another in olden days. What hardships did they have to suffer?

Although it is a common proverb that ‘Old is gold’ but it is not always true. When it is the question of travelling or means of transportation, one can find a huge difference between the era before the invention of modern transportation and the present time with the latest means of travel. People really had to suffer hardships if they had to travel somewhere. Usually, feet were considered the most significant mode to travel from one place to another. Before the inventions of airplanes, rockets, ships etc people used to travel on foot or own animals or animal carts for travelling purposes. It took days, months or even years to reach their desired destination. That’s not all; they had to tolerate severe weather conditions too, for instance, those who had to travel in deserts had to bear the scorching heat of the sun for so long. Travelling in olden days was just like hard-earned money as some people lost their precious lives in order to attain that.

Q 10. What revolution has taken place in the field of transportation due to modern technology?

Due to the emergence of modern technology in the life of mankind, great advancement can be seen and experienced in almost every walk of life. The revolution that has taken place in the field of transportation due to modern technology and the efforts of mankind is simply unbelievable. The first and the foremost feature that appears due to advancement in the field of the transport system are the integration and compression of the world. This system squeezed the whole world by immediately connecting the villages to cities, countries to continents and planet Earth to the moon with an enormous network of roads, speedy railway system, an efficient ship travelling, exciting air tour, bullet speed rockets and space shuttles. Before this expansion, people had to suffer extreme hardships in travelling. Now they are in much better condition and situation to travel to any part of the world without any hassle or fear. It is just a matter of hours, minutes or sometimes seconds that counts a lot in taking not only a single individual but a great number of people to their desired destination with ease and comfort. One can say that revolution in the field of transportation actually gives worth and weight to valuable time which was wasted in travelling in the past times.

Livestock, food industry and agriculture develop by leaps and bounds and are greatly affected due to modern technology. By using new scientific innovations, people transform the condition of barren and arid lands and bring them under the plough. Dams are constructed and tube wells are installed to provide better ways for irrigation. Electricity can easily be generated in bulk due to dam construction. The agriculturists of modern times are in much better circumstances as compared to the past time farmers to increase their yield per acre according to their needs and requirements.
The invention of chemical fertilizers gives boom in the bumper production of a number of crops. Now, the agriculturists are using good quality seeds, varieties of crops, pesticides, more milk production, and processing and the preservation of food in a proper way. That is not the end; the modern technology in the field of agriculture gives liberty to the farmers to cultivate and grow vegetables and fruits out of season and can earn their livelihood throughout the year.

Q 14. How can we put an end to load-shedding and energy-crisis?

Load-shedding and energy crisis are the most attention gaining issues all over the world especially in developing and underdeveloped nations. The best source that has the potential to provide unlimited energy for domestic and commercial use is solar energy. This form of energy is not only safe and potent but everlasting too. Most of the warmer countries of the world are using solar energy for limitless energy production. Scientists all over the world are trying to use the atom for peaceful purposes. If they are successful in achieving their dream, we would for sure be on a positive end of the path to eliminating load-shedding and energy crisis from the face of the earth. Thus, making the lives of mankind more comfortable to live.

Q 15. What is solar energy? Can it be a suitable substitute for fuel and coal energy?

As the name indicates solar energy means the energy that is provided by the sun without which nothing could exist on this planet earth. For many years, it is considered one of the biggest and evergreen sources of energy only if harnessed by effectively using modern technology of the world. The best part about solar energy is that it is abundant and freely available, at least in most parts of the world.
Solar energy has the potential to be used for domestic as well as commercial use without any hazard.
Yes, it can be said that solar energy is a suitable substitute for fuel and coal energy for a number of solid reasons which are as follows:
1. Solar energy or projects employ more workforce providing more jobs to the masses. In 2012, solar added 14,000 new jobs, up 36 percent from 2010 and the industry will add another 20,000 jobs in the following year. The fossil fuels industry cut 4,000 jobs last year.
2. Solar panels have a seen a consistent drop in prices over the last three decades. Since 2008, the cost of coal has risen 13 percent. In some parts of the market, solar has already reached parity with coal. Two-thirds of global solar capacity has been installed over the last two years. In contrast, 175 coal-fired power plants in the U.S. are expected to be shut down over the next five years. This reflects the rising costs of coal and the implementation of stricter environmental regulations.
3. Solar energy is more environment-friendly as compared to fuel and coal energy as acid mine drainage and coal sludge pollutes rivers and streams, coal dust from mining causes respiratory illness and coal combustion waste is the second largest contributor to landfills after solid waste
In a nutshell, it is evident that solar energy is an efficient competitor of coal and fuel energy.

Q 16. Atomic energy is a big source of energy. How can it be used for peaceful purposes?

Atom is the vital component of every living being, the energy released from the atom is known as atomic energy. Atomic energy is considered as one of the greatest discoveries of mankind that are subject to both constructive and destructive activities carried out by man. No doubt, it is really a huge source of energy that’s why nearly all the countries of the world including the under-developed or developing nations are ever-ready to utilize it to the maximum. There are numerous ways in which it can be used for peaceful purposes to facilitate humanity and improve the well-being of the masses. Following are some of the ways in which it is used for creating peace in the world:
1. The world is facing a serious issue of the energy crisis, in order to overcome it, scientist found the solution in atomic energy. It is an inexhaustible source of power that can be used in different fields of life such as agriculture, industries and in electrifying the remote areas of the countries.
2. Atomic energy can be used in the field of agriculture to a great extent. The radiation from atomic energy has the capability to improve the present varieties of fruit, vegetables, and crops. In this way, the world would relish and cherish the all-new diversity of crops. It can also be used as pesticides to kill the disastrous insects that destroy the yield.
3. The best use of the atomic energy is in the field of medical sciences where the diseases of the thyroid have been classified with the use of radioiodine.
4. It can help in easy generation and regeneration of water to produce electricity.
5. With the help of atomic energy, the problem of clean drinking water can be resolved by distilling sea-water.
6. Factories and industries are also able to improve their goods by using atomic energy.
That’s not all; there are numerous other benefits of atomic energy in various fields such as communication, transport, industry, and irrigation. So, in order to live in a world surrounded by peace, we all have to join hands together to make positive use of atomic energy rather than focusing on the negative or destructive ones.
