A vegetarian diet is often praised for its health benefits. Studies have shown that vegetarians usually have lower levels of heart disease and a lower risk of diabetes than people who eat meat. What most people are less aware of, however, are the effects that a vegetarian diet can have on the environment.

Researchers from the Union of Concerned Scientists in the US recently studied how consumer behavior affects the environment. The study showed that meat consumption is one of the main ways that humans can damage the environment, second only to the use of motor vehicle.

Then, how can eating meat have a negative effect on the environment? For a start, all farm animals such as cows, pigs, and sheep give off methane (沼气) gas by expelling (排出) wind from their bodies. One cow can produce up to 60 liters of methane each day. Methane gas is the second most common greenhouse gas after carbon dioxide. Many environmental experts now believe that it is more responsible for global warming than carbon dioxide. It is estimated that 25% of all methane released into the atmosphere comes from farm animals.

Another way that meat production affects the environment is through the use of water and land. 2,500 gallons of water are needed to produce one pound of beef, whereas 20 gallons of water are needed to produce one pound of wheat. One acre of farmland used for crop production can produce 40,000 pounds of potatoes, 30,000 pounds of carrots, or 50,000 pounds of tomatoes.

Many people now see the benefits of switching to a vegetarian diet, not just for health reasons, but also because it plays a vital role in protecting the environment. However, some nutritionists advise against switching to a totally strict vegetarian, or vegan diet. They believe a vegan diet, which excludes all products from animal sources, such as cheese, eggs, and milk, can be short of many necessary vitamins and minerals our bodies need.

Today, many people know it’s important to take better care of their bodies and to use the earth’s resources more efficiently. As this understanding spreads, more people may realize that to help the environment and for the human race to survive, more of us will need to become vegetarians.

Beijing Daxing International Airport (PKX), also known as Beijing New Airport, is the biggest airport in the world. It is also the second international airport of Beijing along with Beijing Capital International airport. The airport's design is pioneering while its location on Daxing District (the southern suburbs of Beijing) is perfect in order to serve the Chinese capital and the neighboring areas of Hebei and Tianjin. The new mega-airport hub (大型枢纽机场) is expected to handle up to 45 million passengers per year by 2021 and reach an outstanding 100 million in the future.

How big is Daxing Airport?

The gigantic Daxing Airport, with the impressive shape which has given it the nickname 'Starfish', has enormous dimensions. There are 4 runways at present (with the hope of becoming 7 in the future) and a vast terminal building (航站楼) covering a 700,000m area while the ground transportation centre extends to 80,000m.

How many runways does Daxing Airport have?

For the time being, Daxing Airport has four runways and 79 airport stands. The 4 runways' size is impressive while the airport stands are suitable both for one twin-aisle (双通道) and two single-aisle planes. Eventually, the airport will have 7 runways in total and will be able to serve about 620,000 flights every year.

Who designed Daxing Airport?

Daxing Airport's terminal building is the impressive outcome of the cooperation between ADP Ingeniérie (ADPI) and the architecture team of Zaha Hadid (ZHA) who tragically passed away in 2016. As a result, in August 2018, Hong Kong design studio Lead 8 undertook the design of the new commercial terminal which is expected to meet every passenger's needs.

How much did Daxing Airport cost?

The construction of the mega-airport, which is expected to eventually become the busiest airport in the world, cost an unsurprisingly large amount. The Chinese government is estimated to have paid about US $17.47 billion for this great project.

With our city's first subway comes into use, great changes have been taken place recently. Many people preferred to take the subway instead of driving cars, because it's fastly and eco-friendly. Under the help of the subway network, traffic jams and road accidents have declined sharply, making that convenient for people to travel. In the meantime, we can enjoy clean airs and see a blue sky. Living in the present city, I can feel the strong sense of happiness. Beside, what makes us excited is it has connected the city with the towns nearby. I wish our city would be better and better.

“Funny”, a made-in-China emoji, seems to have recently moved beyond China. Now, it is more than an emoji, but a cultural expansion.

● Reaching Global Markets

A series of “funny” emoji-based bolsters(抱枕) have attracted the attention of Japanese customers. Even if one bolster is more than three times as expensive as in China, it doesn’t kill their desires to buy it. One Japanese customer Miki said, “They are just so cute and I bought three bolsters at one time for my family. And every time I see them, my mood just brightens suddenly.”

A Japanese netizen Kiro Kara said, “I think the emoji implies very complicated meanings. My dad will send it when he doesn’t agree with someone but he has to say something and behave politely.”

● Addition to Domestic Social Media

Compared with Japanese impressions of the “funny” emoji, Chinese netizens prefer to use the emoji to tease one another on social media.

One commonly seen online comment is, “We strongly suggest stopping the usage of the emoji. Because every time other people send me the emoji, I feel very uncomfortable and consider myself as a fool.”

Regarded as the most popular emoji, the “funny” emoji has received much attention since its release in 2013. In fact, the “funny” emoji is the updated version of its original one; “funny” has a smiley mouth, two eyebrows and a naughty look. All these characteristics present users a sense of satire(讽刺).

● In Everyday UseAbroad

It’s not the first time the Chinese emoji takes the world stage. Earlier this year, one emoji from the Chinese basketball celebrity Yao Ming has been spread through the Middle East region. In a city in southern Egypt, Yao’s smiling emoji has appeared frequently in local traffic signs to remind people the road ahead is one-way. Many locals do not know Yao Ming but are familiar with his emoji and nickname “Chinese Funny Face”.

As a new online language, emojis have become a necessary part of people’s daily life, helping people express their views in a more vivid and precise way. Also, it can help foreigners learn about Chinese culture. But how to properly use “the fifth innovation in China” without hurting others and turn them into commercial advantages still need answers.
