Your Food Choices Affect the Earth's Climate
Every action has a cost, even for growing food and delivering it to your dinner plate. A team of researchers has found that meat production releases more climate-warming pollution than it does when producing fruits, vegetables, nuts and grains. Their calculations suggest that people could do a lot to slow global warming if they limited how much meat they eat.
There are plenty of "costs" of food. As to the visible costs, people pay money for the food as well as the fuel needed to get groceries to the store or restaurant. However, producing foods also takes resources, for example, the water used to irritate (灌溉) crop fields or the fertilizer and chemicals used to promote plant growth and fight pests.
Peter Scarborough at the University of Oxford in England decided to calculate some of the less-visible pollution created by food production. His team focused on greenhouse gases emitted through the production of our food, including carbon dioxide(CO2), methane(甲烷) and the nitrous oxide. All three gases are important. While CO2 is the greenhouse gas released in the highest volume, methane and nitrous oxide stay in the atmosphere far longer than CO2 does. As such, they are more powerful in warm the earth's atmosphere.
They used a computer to change the methane and nitrous-oxide emissions for each person's diet into its carbon dioxide "equivalent." That's the amount of CO2 needed to warm Earth's atmosphere by the same amount as the methane or nitrous oxide would.
As for the calculations of the carbon dioxide "equivalent(等量)", in the 1990s, a survey asked65,000 adults what they typically had eaten throughout the past year. Scarborough's team fed those data into a computer and then included the amount of green house gases linked with producing nearly100 common foods. Then the computer matched those green house-gas amounts to the mix of foods each person had reported eating.
It shows that the diet of someone whose meals included an average of 50 to 99 grams of meat each day would be responsible for the daily release of 5.6 kilograms of CO2 equivalent while those vegans had the lowest diet-linked greenhouse-gas emissions (2.9 kg of CO2 equivalent).
Its authors conclude that reducing the intake of meat and other animal-based products can make a valuable contribution to climate change reduction. And compared to meat, more plant-based food calories can be grown on more lands with less water and other resources. In places where many people are going hungry, raising meat may make it harder to ensure that everyone gets enough to eat.
Plant-based food can adapt to more types of lands than meat, but they may have a higher requirement of water and other resources, which can be a disadvantage of such food.
Put a group of strangers in a room together, and they'll probably start a conversation. "Hot today, isn't it?"one might say. "You said it." another replies.
Why do we talk so much about the weather? When we meet new people, we don't begin by telling them our life story. We start with small talk, a polite conversation about something like traffic or weather.
Research suggests that small talk can build new friendships. When we begin conversations with new people, we want to feel comfortable, and so do they. We use small talk to find common interests. Once we have a common interest, a friendship can begin.
Small talk even helps people get hired. In order to impress at a job interview, you need to bond with the interviewer right away. Proper small talk can make that first impression get you the job.
So, how can you make small talk lead to a new friendship or job? First off, find common ground. Select something around you that you share with the other person.
Next, keep the conversation going. Compliment (赞美) the other person to make himor her feel comfortable, and ask questions to show interest.
Third, keep eye contact (接触). When you look people in the eye, they feel you appreciate what they are saying. It makes you appear honest and builds trust.
Naturally, shy people might not have enough confidence to start up conversations with strangers. Talking to someone you don't know is not the easiest thing to do! Some experts say with more practice, small talk does get easier.
Some people avoid small talk because they dislike discussing things like traffic or weather. For them, they are just too small. However, when you think about it, small talk is anything but small. In fact, it is actually a very big deal!

Maybe you are an average student. {#blank#}1{#/blank#} This is not necessarily so, however. Anyone can become a better student if he or she wants to. Here's how.

Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won't end if you don't pass a test, so don't be over worried.
