Purchase less toxic cleaning supplies. Use double-sided copies. Set all computers to print double sided. Join the Clean Air Zone Program and actively encourage parents to adhere to the signs by no idling. Use energy-efficient fluorescent lights and properly recycle them when they are spent.

Today, mobile phone has become popular to everybody [This is an over-generalization: many people do not like them. Use "most people" or something similar] since it is very convenient. The most advantage of having a mobile phone is you can communicate to your family and your friends no matter what where you are. For instance, you can contact easily to your friends by calling or sending messages everywhere without electricity. It is maybe the main reason why almost all [good, but still, is it true?] people today choose to own a mobile phone. From the customer’s point of view, it is obvious that mobile phones assist you in business a lot, such as, make schedule of working, surf the internet, and keep in touch with their companies. Moreover, you can relax with mobile phone’s applications, for example, play games, listen to music, or chat with your friends.

On the other hand, there are also disadvantages. Using a lot mobile phone can harm your brain, particularly teenager and children who are under 16 years old. If you use mobile phones too much, you will get bad effects like dizzy, blood-brain barrier [the blood-brain barrier is simply the normal anatomical barrier between the bloodstream and the brain; it's not a condition] , or ears problems. In addition, when you use mobile phones while you are driving, you will get an accident. It is essential not good for you and others. Moreover, “radiations emitted from the phone are dead harmful for the eardrum”, has proved by many scientist.
[You haven't discussed the irritating effect on other people in restaurants, buses etc. from users shouting down their phones].

Owning a mobile phone in your hand is you can solve many issues and hold most of information around the world. Even though is not good for your health and you have to protect yourself from bad effects of mobile phones if you choose to have one.

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. 

Priority is:

-Save time.

- Flexibility when shopping.

-Easily compare prices and quality of items.

- Wide variety of items.

-Buying does not cause harm.

- Avoid unpleasant distractions.

The downside is:

-You can't actually see the products you buy

. -You have to wait for delivery.

-Your purchase may be mishandled in transit.

-You may be a victim of an Online scam.

- You cannot buy perishable products.

- You have to spend a lot of time hunting for offers

     

In my opinion, everything has two sides. Online shopping too:

Firstly, online shopping makes it easier for both buyers and sellers, easy to exchange, convenient, no need to go far, easy, fast. And online shopping is also a popular business, to increase income, and buyers are presented with more choices.

Besides, it is equally risky. Online shopping sometimes between buyers and sellers have not yet reached an agreement. Or maybe it's just funny advertising, but when it comes to users, the quality is poor.

Advantages:

1. Save time

2. Flexibility when shopping

3. Easily compare prices and quality of items

 4. Full variety of items

 Disadvantages:

 

1. You have to wait for delivery

2. Your purchase may be mishandled in transit

3. You can't buy perishable products

4. Spend more time shopping online

 

And finally, I want to say that online shopping is very quick and convenient, but don't always focus on online shopping and forget about daily work.

 

 

 

 

 

 

 

 

 

 

 

 

 

   

 

1. Lifebuoy Matcha shower gel

160,000 VND

I bought Lifebuoy Matcha shower gel last month, and I would say it's a good product for the body. This product is extracted from two natural ingredients, matcha and bitter melon, to help kill bacteria and purify the skin from dirt. In particular, those who are experiencing difficult-to-solve back acne, regular use of this product will help remove dirt in the pores, reduce inflammation, and limit acne scars so that you can confidently show off smooth, blemish-free skin. The downside is that the product can cause irritation to sensitive skin because of its bactericidal effect, you should research and test it before long-term use. It's really a must-have item, so I will give it 5 stars.

2. Bluetooth headphone HOCO

(Tai nghe bluetooth HOCO)

300,000 – 500,000 VND

This is a product with an affordable price, suitable for many people. It’s very convenient to listen anytime, anywhere. In addition to advantages such as sound quality and great design, it also has ear pads that help the wearer feel no pain when using. The biggest disadvantage is genuine accessories are not available, so that it will be difficult to replace when damaged.
