Advantages of Science and Technology
The vast improvements made in the field of medicine have served to lengthen our life expectancy and to reduce the rate of infant mortality. The discovery of mechanization, better seeds, better techniques of irrigation and pest control, has worked to increase productivity levels on farms. In transportation, railway, modern ocean liner, jet plane, and motor vehicle have made our lives more comfortable and provided great possibilities for modern commercial development and industrialization. The invention of the computer has assisted the process of calculation in laboratories Technology has made communication much simpler in recent times. Science has brought about groundbreaking solutions to numerous deadly diseases. Man is able to explore the space extensively because of the wide-scale development in technology. Our life has become healthier and longer. Modern hygiene, sanitation, medicine and surgery are conquering more and more physical and mental ills day by day. We now know and experience the joys of good health and longevity. Disadvantages of Science and TechnologyMachines have led to unemployment. They have polluted water and atmosphere. They have caused noise pollution. Factories have led to slums where human beings live in squalor. Our moral and spiritual progress has failed to keep pace with our scientific progress. We have allowed science to master us instead of using it as our servant. Machines make us mechanical, deaden our sensibilities, stifle our creative talents, force mechanical regularity, uniformity and boredom upon us, increase our wants and desires, and tend to make us selfish, greedy and cruel. Geographical distance has, no doubt, vanished, but the gulf between the minds and hearts of man has widened. Machines have given man leisure, but man misuses it to get cheap and vulgar entertainment which destroys his physical and mental health.Again, science has put in our hand’s such fiendish weapons as a nuclear bomb, the guided missile and means of chemical and biological warfare.

Talk like and dislike about life in the countryside
Living in the countryside has a lot of advantages, but also many disadvantages. As the advantage we can consider the fact that the country is less polluted and the traffic isn't so heavy. You are fit and you don't need to worry about your health condition, because in the countryside the air and water are so clean. In the country there are many plant species. There aren't any huge blocks of flats, modern skyscrapers or bothersome traffic jams. In the country you are free to admire the breathtaking landscapes such as huge meadows, peaceful hills or forests. You can enjoy walking in the forest and picking mushrooms or hunting. Another advantage is that you may easily build a big house and the garden, because charges for ground are much lower than in the suburbs. Moreover, living in the countryside is cheaper than it is in the city, so you probably may afford many other things, because the prices are lower. What is more, you can invite your friends to the barbecue organized in your garden. It would be great! The other positive side is the safety. In the rural area the crime rate is much lower. There aren't a lot of housebreaks and the possibility of burglary is also lower. In the countryside people usually and keep eyes on neighbour's estates. They always react when something strange is happening. Country life is very peaceful and silent. You will enjoy the feeling of peace.
However, there are a lot of positive aspects of living in the country side, there are also some disadvantages. Living in the country is slower. People don't need to hurry and have a lot of time. People in the country don't have to work so many hours as they do in the city. On the other hand, they don't earn so much money. Moreover, there aren't such interesting things to do during free time. The unemployment rate is also much higher than in the city. The problem may be also the communication. If you don't have your own car, you may have problem how to commute to work. The same problem concerns the access to the hospitals, schools, police stations and shops, which are usually located far from the village. Last of all, there are some dangers connected with country life such as heavy snowfall or rainfall.
To sum up, I think that living in the country may have a lot of advantages such as fresh air, breathtaking landscapes and comfort, but a lot of people decide to stay in the city, due to the fact that the life in the town is easier. The easy access to shops and other institutions are the great advantage.
