Is technological development more beneficial or harmful? Essay 700 words

Leda: It manifests itself in many aspects: from the medical perspective: the emergence of various modern technologies, laser surgery, etc., has saved many people’s lives; from the astronomical aspect: the invention of artificial earth satellites and spacecrafts , such as meteorological satellites, can accurately predict weather changes in the future, providing convenience for human production and life; from the aspect of human life: various electrical appliances make people's lives comfortable, such as air conditioners, which are warm in winter and cool in summer; of course , Scientific progress is inevitably accompanied by negative effects, but the positive aspects account for the majority after all.

Since the advent of the Internet, there have been people surfing the Internet; as long as there have been people surfing the Internet, there have been people talking about the pros and cons of surfing the Internet. Today, as a college student, how do I view college students using the Internet? I think it should be divided into two parts.

The Internet was originally used by enterprises to check the information required by the company and to negotiate business. The Internet at this time was not yet popular, but its role was positive. At this time, apart from the fact that the network is not yet perfect, I think there are no pros and cons.

With the improvement of technology, the Internet is becoming more and more perfect and becoming more and more popular. In order to better meet the needs of the public, there are online games, QQ, and various sections. As a result, more people are surfing the Internet, including college students of course. College students use the Internet for various reasons. Some are looking for an online friend to pass the time; some are playing online games day and night; some are playing online movies to "enrich" their lives. Of course, it’s also for learning. I personally heard that an architecture student booked two nights to draw pictures. Let’s not talk about whether his behavior of staying overnight is inappropriate or harmful to his health. Let’s just talk about his use of the Internet. He is using the Internet. I have to interject, what does "use" mean? I think, here, utilization is not a derogatory term, but a positive and effective application. Today, as technology becomes increasingly advanced, with the help of computers and the Internet, many things can be done that could not or were not easy to do in the past. Is this a benefit? Is it a disadvantage?

As a tourism student, I often use the Internet. On the Internet, you can see a lot of information about travel. There are introductions to scenic spots, the release of tourism information, and the announcement of national tourism policies. These can be said to be the latest and fastest. For a sensitive industry like tourism, getting information early means seizing opportunities early. Is this a benefit? Is it a disadvantage? Of course, not all information on the Internet is reliable. There are also rumors and fallacies. If you accept them all without distinguishing them, it will lead to huge mistakes. Is this a benefit? Or is it a disadvantage?

The Internet extends in all directions. If you go online, you can get to know many people. Local, foreign, Chinese, foreign, of course there will be good people and bad people. When you go online and have netizens, you can communicate with each other, communicate with each other, provide each other with opinions and suggestions, and build a good online friendship. Is this a benefit? Or a disadvantage? Indulging in online chatting all day long, not going to class, not doing anything, just surfing the Internet, and having vague interactions with people on the other end of the Internet for a long time, you may end up going astray. Is this a benefit? Is it a disadvantage?

Everyone says that the Internet is wonderful. It can present what you want to know in an instant; you can search for an old magazine that you have always wanted to find but couldn't find; you can search for Some cutting-edge knowledge that has not yet appeared in books and newspapers. You can use it to enrich yourself and truly reach a state where you can know everything about the world without going out, and you can reach a state where you can know cutting-edge science with just one computer. Is this a benefit? Or a disadvantage? There is also a type of people who have excellent Internet knowledge and use the Internet to make a fortune, a kind of ill-gotten wealth. Of course, the utilization here is not the utilization I mentioned above. This is also a kind of utilization, but a destructive one. Is this a benefit? Is it a disadvantage?

In fact, the Internet has no pros and cons. The pros and cons lie in the people who use the Internet. After learning from Ma Zhe, I know that people should give full play to their own initiative, and the same is true for surfing the Internet. Sometimes, there is only a thin line between advantages and disadvantages. It just depends on how people who use the Internet grasp it and how they use their own initiative.

Nowadays, it is a trend for college students to go online. It can also be said to be an inevitable situation. Some people still talk about the pros and cons, but isn’t it in your own hands to grasp the pros and cons?

Big Disadvantage: It is said above that each of us sees higher and further, which makes us see things that are only far away and higher, explore and pursue them, and ignore What we should do now is just like those monarchs in history who wanted to live forever. Medicines were used to treat diseases. As a result, they invested blindly in order to achieve something that was impossible, and in the end they harmed themselves. After harming the people, there are the macro scenes that people now see in movies, the chilling burial of emperors and those so-called miracles of the world. The development of science and technology brings convenience to people, but it also brings disasters. Lee: We can go where we want to go. People are constantly exploring. In the future, the "Sun Center" society may be overturned. Nowadays, with the development and progress of science and technology, no one can enjoy what those historical figures cannot enjoy. Every new person is interested in this world. With the development of economy, the acceleration of people's life rhythm and the improvement of living standards, the consumption of plastic is increasing day by day.

In 1996, my country's plastic packaging consumption reached 2.43 million tons, with an average annual growth rate of more than 20%. In particular, plastic waste in garbage in cities, along major transportation lines, and tourist attractions has increased rapidly.

According to surveys, Beijing’s annual domestic waste production has reached 3 million tons, of which waste plastics account for about 3%, with an annual growth rate of 48%. The plastic content of garbage in coastal cities is higher, reaching 8-10%. The proportion of these waste plastics in the garbage has reached more than one third if calculated by volume, and it has greatly increased the difficulty and cost of garbage disposal.

Since waste plastic is difficult to degrade for hundreds of years, if it is discarded in the natural environment, it will provide a breeding ground for mosquitoes, flies and bacteria to survive and breed; if it is buried underground, it will easily pollute groundwater and hinder plant roots. growth, destroying soil quality and affecting crop harvests; if burned with fire, a variety of toxic gases will be produced. "White pollution" has become a major public hazard that harms our country's social environment and has seriously hindered the sustainable development of our country's economy and environment.

Currently, my country’s annual consumption of disposable tableware is about 10 billion pieces, mainly foamed plastic products, which damages the environment. Harm to nature:

Like any industrial product we use, air conditioning will inevitably bring a certain burden to our environment. A few years ago, the impact of air conditioning on nature was mainly focused on the damage of refrigerants to the earth's ozone layer, but in recent years, due to the development of refrigerant renewal schedules, this is no longer the main factor. In the future, the impact of air conditioning on nature will still be reflected in the field of energy consumption. Air conditioning energy consumption already accounts for a large proportion of the total energy consumption in our lives and industries. The development of energy and the release of a large amount of heat into the atmospheric environment have placed a great burden on our natural environment. This is a major problem that we have to solve for a long time.

Computer: Because of the computer, there is the Internet, and there are online games. Therefore, teenagers are unable to extricate themselves, neglect their studies, and have nothing to do.

Cars: Population is expanding. If every person has a car, will there be room for human beings to live?

Air conditioning: reduces people’s ability to adapt to the natural environment and reduces immunity.

I think the most important thing about this debate is not to list the various disadvantages that technology has brought to mankind, because if your eyes are only focused on the disadvantages, then the other party is likely to seize this point and attack you: the other party Debate friends, you always list the various disadvantages of science and technology. It seems that the development of science and technology only brings disasters to mankind. So why do we still emphasize that science and technology are the primary productive forces? Why do humans continue to develop science and technology?

Remember this saying: Technology is a double-edged sword. On the one hand, it can smash ignorance and backwardness, but on the other hand, it can also bring endless disasters to mankind. At this time, we emphasize the pain and disasters that technology has brought to mankind precisely so that this double-edged sword can maximize its positive role in benefiting mankind instead of the other way around. It is said that good medicine tastes bitter but is good for disease. This is because rational and comprehensive thinking about science and technology can keep science and technology under the control of mankind and not harm mankind in turn.

Conclusion: The development of science and technology is important, but it cannot be developed on the premise that it can be used reasonably and normally. Development must first purify the mind. Only when the individual's mind and soul are developed and improved can the developed technology be developed. High-tech development can permanently benefit human development and the harmony of nature!
