A rising population is one of the main reasons that there is global warming. Between 1650 and 1850 the population increased by 0.75 billion people going from 0.25 billion to one billion. From 1930 to the end of the century the population rose from two billion to over six billion. In just a third of the time the population rose by more than five times what it did before. It is expected that this trend in the changing population will continue and could even heighten. The growing population requires increasing amounts of energy. These energy demands and other supplies require production, which almost always involves the emission of greenhouse gases. The more the population increases the more greenhouse gases that are produced and the greater the increase in temperature.

    The burning of fossil fuels is one of the best-known causes for global warming. The major reason for fossil fuels contributing so much to global warming is the release of carbon that occurs during the burning of fossil fuels. When people burn fossil fuels, they release large amounts of carbon by way of the release of carbon dioxide. The carbon dioxide in the air then leads to global warming.

    Another source of carbon dioxide comes from deforestation. In forests there is a large amount of carbon that is stored in the trees and other plants. This carbon is out of the atmosphere because the trees consume the carbon from carbon dioxide. When people cut down trees, they are frequently burned. This burning releases the carbon dioxide into the atmosphere that was stored in organic matter. Even when new trees are planted, it can take up to one hundred years to make up for the carbon that was released. It is commonly thought that because trees absorb more carbon dioxide, the atmosphere experiences positive effects.

    Sophie Armstrong, the writer of Earth Care put it, “There's no doubt that the earth is becoming warmer because of human activity rather than a random but natural phenomenon.

    Travis is the manager of G&G where he is responsible for forty employees (雇员)and profits (利润) of over $2 million per year. He's never late to work. He does not get upset on the job. When one of his employees started crying after a customer screamed at her, Travis took her away. "Your working uniform is your shelter," he told her. "Nothing anyone says will ever hurt you. You will always be as strong as you want to be."

    Travis picked up that lecture in one of his G&G training courses, an education program that began on his first day and continues throughout an employee's occupation. The training has, Travis says, changed his life. G&G has taught him how to live, how to focus, how to get to work on time, and how to master his emotions (情绪). Most importantly, it taught him willpower.

    At the center of that education is an extreme focus on an all-important habit; willpower. Dozens of cases show that willpower is the single most important habit for a person's success.

    And the best way to strengthen willpower is to make it into a habit. "Sometimes it looks like people with great self-control aren't working hard—but that's because they've made it automatic," Angela Duckworth, one of the University of Pennsylvania researchers said. "Their willpower occurs without them having to think about it."

    The company spent millions of dollars developing programs of study to train employees on self-control. Managers wrote workbooks that serve as guides to how to make willpower a habit in workers' lives. Those courses arc, in part, why G&G has grown from a sleepy company into a large one with more than seventeen thousand stores and profits of more than $10 billion a year.

    Settled by the Celts, invaded by the Romans and the Normans, and ruled by the English, Wales' population has regularly changed over the ages. Wales, particularly South Wales, became a melting pot (熔炉) of European nationalities and cultures. At first workers from England, Ireland and the rural areas of Wales rushed into the coal mines of South Wales. By 1911, workers from Ireland, Italy and Spain had joined the industrial workforce (劳动大军) there. Many of these newcomers were prepared to work for less pay.

    But during this period, workers, dissatisfied with regular pay cuts, poor safety, returned to the land. In 1891, the rural population of Wales was about 616,000 and by 1911 just over 649,000 people lived and worked in these areas.

       The rural population continues to grow slowly even today. People from richer parts of the UK, particularly southern England, are buying holiday homes in Wales. In some areas this has led to a lack of housing for local people. This, combined with the lack of employment in rural Welsh communities, has started a new movement of people in search of jobs and homes into the towns and cities of Wales and to other parts of the UK and Europe.

    As so many Welsh people have moved to other countries over the last 200 years, it's really no surprise that many visitors come to see friends and relatives. These visitors strengthen their links to their land of origin and continue to support the Welsh's development. During the hot summer days, about 28% of the visitors visit the countryside and nearly 70% visit the seaside.

    My daughter Kelly is a cautious person. She needs to warm up to situations' and is hesitant to try new things. When with close friends, she becomes a leader who laughs loudly and chants, “Girls rule, boys drool.” But when that comfort zone is not around her, she is shy and nervous.

    This has been challenging for me at times. “Shy” is not a word that I think has ever been used to describe me. But this has been a year of firsts for my girl that has filled her with a new sense of confidence. This year she moved to lap lane in swimming where she was preparing for a swim team. This year she learned to ride a bike without training wheels. And this year she completed her first kids' triathlon (三项全能).

    On Saturday, with a thunderstorm coming soon and my son's birthday party later in the day, we all went out in the dark of the morning for Kelly to participate in her first triathlon. We practiced transitions from swim to bike to run with her, we got all the equipment she'd need, and we kept talking about the race. But as we waited the two hours for the older kids to finish before her turn, she held my leg a little harder and told me she loved me a few too many times. She was nervous but trying to keep it together.

    And then it was her turn. From the second she jumped into the water, my heart soared. My daughter transformed into the most confident human being I had ever seen. She dominated that swim, crushed that bike ride and ran to the finish with the biggest smile on her face.

    I can honestly say that I never felt so proud of someone in my entire life. It wasn't because she did a sport or anything like that. It was because she was afraid of something and conquered that fear with confidence and a fire I hadn't seen before.

    All day I would find myself just looking over at her and smiling. She might be wearing the finalist medal but I felt like I won that day. I won the chance to see my girl shine.

Shine on, sweet baby.

Tea is currently the world's most popular drink, only after water. However, there was a time when tea was known only to the Chinese. So, how did tea originate in China? And how did it get to conquer the world to the extent that people often describe something they really like as their "cup of tea"? 

While we know that tea drink started in China, its true origin remains something unknown. Legend has it that about 5, 000 years ago, Shennong came across tea when dried leaves blew into a pot of boiling water. Following his discovery, tea was used as medicine, included in meals and later offered as a refreshing drink to officials and noblemen. Eventually, it became a common drink enjoyed by all Chinese people. 

The love of tea inspired many people to write about it. Over the years, tea drinking became an important part of China's rich culture. The great poet Du Fu described his tea-drinking experience in poetic language. Lu Yu, a tea master, wrote The Classic of Tea, which remains the earliest and most famous detailed study on tea in the world. 

It is then not surprising that the beauty of tea was eventually spread to a wider world. Tang and Song Dynasties needed strong Tibetan horses, so the Tea Horse Road was born. Porters (脚夫) carrying back-breaking loads of tea bricks made their way through dangerous snow-covered mountain passes, to trade Sichuan and Yunnan tea for horses. Over time, the gift of tea was further delivered to Western Asia and Easten Africa. As early as the Tang Dynasty, Saicho, a Japanese monk came to study in China and took tea seeds and tea-making customs to Japan. Around the 1600s, tea was shipped to Europe from China by Portuguese and Dutch sea traders.

In Bududa, a lush yet landslide-prone district of eastern Uganda, Mary Butsina and a growing number of other women farmers are building their livelihoods around coffee. "I'm supporting all of my 10 children with it." says the 36-year-old, holding a red bucket.

From farming stock, Mary first went to work with her father at the age of 10. Profits from his coffee crop covered her school fees. She married into coffee too, with her husband giving her 100 trees as a wedding present. But Mary's since planted more than 300 herself and joined a women's cooperative. "The aim was to reduce the dependence of women on men in coffee." Mary says, though husbands are allowed to join too—as they tend to own the coffee plantations and support their wives. "More women have started to plant their own coffee." she says. 

Mary rises early every day to pick the coffee cherries. "It's hard work but when you concentrate it can become easy." says Mary. After gathering the ripe fruit, she puts it in a bucket of water to weed out the unhealthy cherries. The beans are then fermented (发酵) in water for at least two days before being laid out to dry in direct sunlight. Once dried, the beans are gathered up and later collected by Endiro Coffee, a social enterprise working with women-led, organic farms. The coffee is later milled, roasted and ground, ready for use.

It hasn't been an easy journey for the Bududa farmers, who've faced annual landslides for the past 15 years. In 2018, Mary's mother's house was destroyed and she lost some of her coffee plantations. She dreams of living in a solidly built house with water nearby, so she doesn't have to trek (跋涉) a long way to fetch it－but these will take time to save for. "I've worked a lot and I don't want to stop, but I want my money to work for me." she says.
