I think there are both advantages and disadvantages of online calls. Internet calls are cheap or even free. Many social networks provide free calls for people to communicate. Online calls help us to communicate with people that are really far away from us, for example, our relatives or our Internet friends. Moreover, you can create group calls when you are in need of hosting a conference or a family meeting. However, online calls also have drawbacks. You can’t make online calls unless you have Internet connection. Also, you need a smart device to perform a call. Sometimes, you may get unwanted calls from the person you don’t know.

Tạm dịch:

Mình nghĩ là có cả ưu điểm và nhược điểm của cuộc gọi trực tuyến. Cuộc gọi trên Internet rẻ hay thậm chí là miễn phí. Có nhiều mạng xã hội cung cấp các cuộc gọi miễn phí để mọi người có thể giao tiếp. Những cuộc gọi trực tiếp giúp người ta giao tiếp với những người ở rất xa, ví dụ như họ hàng hay bạn bè qua mạng. Hơn nữa, bạn có thể tạo những cuộc gọi nhóm khi bạn cần tổ chức cuộc họp hay họp gia đình. Tuy nhiên, những cuộc gọi trực tuyến cũng có những hạn chế. Bạn không thể thực hiện cuộc gọi trực tuyến nếu không có kết nối mạng. Hơn nữa bạn cũng cần một thiết bị thông minh để gọi điện. Đôi khi bạn có thể nhận những cuộc gọi không mong muốn từ những người bạn không biết.

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.

rewable:wind,solar enery,hydro,nuclear,biogas...

non rewable:coal,oil,natural gas...i think people will use it more in the future

The main source of energy at present is fossil fuel.

Some alternative sources of energy are wave energy, solar energy, biofuels, natural gas, geothermal power, wind energy, biomass energy, tidal energy, hydrogen gas, etc.

Their advantages are that they are renewable and is most likely to never run out. Also, they are easier to find than fossil fuels. They produce little or no waste that is harmful to the environment like carbon dioxide or methane so they are more environmentally friendly. Their disadvantages are that they don't produce as much energy/electricity as fossil fuels. Another disadvantage is that they rely on their surrounding. For example, wind energy needs to be generated at a windy location and needs wind turbines that take up a lot of space or solar energy needs to be generated at a sunny area and needs lots of solar panels.
