Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.

    During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers(垃圾托运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically(定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.

    Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.

    Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential(住宅区的)neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.

    Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.

    Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.

    There is no better way to enjoy Scottish traditions than going fishing and tasting a little whisky(威士忌) at a quiet place like the Inverlochy Castle. When Queen Victoria visited there in 1873 she wrote in her diary, “I never saw a lovelier spot,” And she didn't even go fishing.

    Scotland is not easily defined. In certain moments, this quiet land of lakes and grass mountains changes before your very eyes. When evening gently sweeps the hillside into orange, the rivers, teeming with fish, can turn into streams of gold. As you settle down with just a people and a basket on the bank of River Orchy, near the Inverlochy Castle, any frustration will float away as gently as the circling water. It's just you and purple, pink, white flowers, a perfect harmony. If you are a new comer to fishing, learning the basics from a fishing guide may leave you with a lifetime's fun. For many, fishing is more than a sport; it is an art.

    Scotland offers interesting place where you can rest after a long day's fishing. Set against a wild mountain and hidden behind woodland, the beautiful Inverlochy Castle Hotel below the Nevis is a perfect place to see the beauty of Scotland's mountains. Ben Nevis is the highest of mountains, and reaching its 1342-metre top is a challenge. But it's not just what goes up that matters; what comes down is unique. More than 900 metres high, on the mountain's north face, lies an all-important source of pure water. Its name comes from the Gaelic language "usqueb" or "water of life"; and it is the single most important ingredient(原料) in Scotland's best known whisky.

    Have you ever heard of a great Chilean poet? He was once referred to as the Picasso of poetry. Beloved by Chileans of all classes, he is one of the most widely read and respected poets in history. And this year is the 114th birthday of Pablo Neruda(1904—1973).

    Born with the name Neftali Ricardo Reyes Basolto, he was a tall, shy and lonely boy. He loved to read and started to write poetry when he, was ten. The American poet Walt Whitman, whose framed picture Neruda later kept on his table, became a major influence on his work.

    However, his father did not like the idea of having a poet for a son and tried to discourage him from writing. To cover up the publication of his first poem, he took the pen name Pablo Neruda.

    In 1924 Neruda gained fame with his most widely read work “Twenty Love Poems and a Song of Despair”. Yet his rich experience as a diplomat and exile made him go beyond the theme of love. His work also reflected the political struggle of the left and development of South America. He was awarded the Nobel Prize for Literature in 1971.

    Neruda loved the sea which he saw as creative, destructive and forever moving. He found inspiration in the power and freedom of the waves and the seabirds on the coast. “I need the sea because it teaches me,” he wrote. “I move in the university of the waves.” He loved how the sea forever renewed itself, a renewal echoed（共鸣）in his work.

    A company in San Francisco, California, has found a way to turn used plastic bottles into women's shoes.

    Every day, millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles end up in landfills or are burned with other waste products.

    A San Francisco start-up company called Rothy's, however, turns this plastic waste into environmentally friendly shoes. Roth Martin is the company's co-founder. He explains how they turn plastic into soft material for women's feet. They take the plastic, clean it, and break it down into small pieces. Then they press them through a device that makes soft fibers. Those fibers are then combined together. This is done by a 3D machine. It is designed to reduce waste while making the shoes. The knitted stuff and the inner part of the shoe are then attached to the shoe's outer part, called the sole (鞋底). This outer sole is also made from environmentally friendly material: responsibly sourced no-carbon rubber.

    Rothy's shoes are sold online. They are flat shoes, with either a rounded or pointed toe. They come in different colors and designs. They cost either $ 125 or $ 145 per pair, depending on the design. After American actress Gwyneth Paltrow discovered them last year, the demand for the shoes grew. Martin says there is no shortage of material to fill that demand. "We're not going to run out of water bottles any time soon. So we have a limitless supply of material, and I think that is a good sign for our future." When the environmentally friendly shoes wear out, customers can return them at no cost to a company that uses the recycled materials to make other products.

    For now, the shoes are only available to be shipped in the United States. However, the company says it will add international shipping in the near future.

    I first began experiencing depression (抑郁) at the age of 14 .At first depression would come and go, but later it became a continual part of my life.

    I was so strongly determined to find the way to overcome my depression that I tried everything from when I was in college, special teas, yoga (瑜伽), and advice given by doctors. However, I still felt I hadn't even come close to managing the problem.

    But one afternoon, I saw an article in a magazine that talked about how dogs were able to help people with depression. The next day, I decided to get a dog—a corgi (柯基犬).

    When I bought my little corgi, Buddy, home, I didn't realize how much he would change my life. One morning, I woke up with those familiar feelings again. I didn't want to get out of bed. I turned to pull the covers back over my head and give up. That's when I saw Buddy. He started jumping all over me, licking (舔) my face, letting me know that it was time to go outside. It was as if he were saying, "There's no time to be sad. The world is amazing!" And for the first time in my life, on a day when my depression were strong, I got out of bed. I put on my winter clothes and went for a walk in the snow with my new friend. I realized at that moment, walking down the street in winter, my life was changing. I really was a new person. This was my new beginning.

    It's been more than a year since that day, and I've never spent another morning unable to get out of bed. I've not cried myself to sleep or spent my days filled with fear and regret. Sure, I still have days when I feel sad or anxious. But with Buddy by my side, I've finally learned how to manage these feelings.

About two weeks ago I saw a very sad, blue eyed, homeless man sitting outside my local coffee house. I said, "Hi! How are you doing today?"

He seemed shocked that I was talking to him. "Not very well, " he replied. He began to tell me how he had been hit by a car while riding his bike. He had been in the hospital for a month and s rest home for another month. During that time the person that paid for his SSI checks （社保费） died of a hear attack and his wallet was stolen with all his IDs. He had several checks waiting for him but had no ID and therefore no access to his money. 

I decided that if this was all true I'd like to help him get a copy of his birth certificate and social security card. I asked him to meet me at the Department of Vital Statistics at 11: 00 p. m. The next morning I didn't see him so I started filling out the paperwork. I explained to the receptionist, "I'm trying to help a homeless friend get his ID hack. " "Bob?" she inquired. "Yes, Bob, " I responded, surprised that she knew his name. "He was here at 9: 30 and he just left, she said, "But he told us you were coming. " I paid the fee and walked out with Bob's Birth Certificate. 

As I was driving home I saw Bob riding back on the old bike someone had given him. I pulled over and jumped out of my car shouting, "Bob! Bob! I got it!" He saw me and rode over. "I got it, Bob! Look, here it is!" He got tears in his eyes and told me I was his guardian angel. 

A few days later I needed him to meet me at the Social Security Office. It took me a half hour to get there by car and at least two hours by bike. But there he was sitting on the sidewalk waiting for me! We were in the Social Security Office for two hours. We got everything straightened out and by next week he will have received his back pay, which is a substantial sum. 

Yes, one person can make a difference in this world. And the interesting thing is that I am getting as much, if not more, from this experience than Bob. I am deeply touched by Bob's sensitivity, his gratitude, his stories, his heart. 

Home is where the heart is, even for the homeless!
