If you live in the U.S., you're probably used to throwing banana peel into the trash. But people in other countries, including India, have been taking advantages of their nutritional benefits for many years.

    While the flesh of a banana is soft and sweet, the skin is thick, hard and slightly bitter. To eat the peel, you can fry, bake, or boil it for at least 10 minutes. Also, the riper bananas get, the thinner and sweeter banana peel will become. That's because of a natural plant hormone(激素) called ethylene(乙烯) that fruits release as they ripen. Ethylene interacts with the sugars and fiber in the banana skin, changing complex sugars into simple sugars and breaking down pectin, a form of fiber in bananas that keeps them stiff. That's why the older your banana is, the flimsier(不结实的) it feels.

    The sweet flesh of a medium-sized banana contains great percentages of your daily recommended intake of various nutrients, such as:

·12% of your daily fiber, which helps with digestion and may help lower your risk of diabetes(糖尿病)

·17% of your vitamin C, which is important for your immune system as well as your growth

·20% of your vitamin B6, which aids the body's ability to turn food into energy

·12% of your potassium, which helps with the development of cells, tissues, and organs throughout the body

    If you eat the skin along with the flesh, you will get an even bigger increase in these same nutrients.

    Eating the peel is not only good for your body but also better for the earth. The average American ate 11.4 pounds of bananas in 2014. Since a medium-sized banana weighs about 0.3 pounds, that equates to about 38 bananas per person, or about 12 billion for the whole of the U.S. And since most of us throw away the peel, that also means a lot of organic waste.

    Ecotourism(生态旅游): A Different Way to Travel

    Are you attracted to obscure(偏远的)places? Do you prefer to vacation away from other tourists? Are you careful to take only memories and to leave only footprints? If you answered yes to more than one of these questions, you just might be an ecotourist.

    Ecotourists are people who want to experience the unspoiled natural world and leave it that way when they return home. This trend started in the 1990s and ecotourism is now growing three times faster than the tourism industry at large. The Ecuador's remote Amazon Basin(盆地) is contributing to that expansion, and it gives a snapshot of what ecotourism looks like.

    At the Ecolodge, a small group of cabins(小屋) sits Kapawi Ecolodge in the middle of the Achuar people's reserve(保护区) and is only reached by air. From here, visitors can explore parts of the Amazon rainforest seen by few outsiders. As they do local Achuar guides explain how the forest is like their supermarket, where they find food, clothing, medicine and tools. As a result, tourists learn to appreciate the local culture as well as the natural environment.

    The owners of Kapawi pay monthly rent to the Achuar people, but they also train the community to run and manage the lodge. They have agreed on a plan to turn the operation over to the Achuar completely by 2011.The owners are working to make ecotourism benefit and empower the local people.

    You probably won't start your own ecolodge, but you can be an ecotourist if you follow these guidelines: Protect the environment; Support local businesses; Respect the local customs and traditions.

    The world is full of fascinating places to visit. As an ecotourist, you can enjoy them yourself and make sure that they remain beautiful for future generations as well.

    Scientists have found that human eyes are more likely to be damaged by UV rays (紫外线) while skiing in the snow-covered areas than sitting on the beach, according to a report by the UK newspaper The Telegraph.

    The researchers at Kanazawa Medical University, Japan and American company Johnson conducted the study together. They looked at the effects of light reflection on newly fallen snow on a ski trail (a rough path) in Ishikawa District, northern Japan. They compared the results with the levels of UV rays on a sand beach in southern Japan's Okinawa District They found that on the beach, eyes are exposed to a daily 260 kilojoules (千焦耳) of UV a square meter compared to 658 kilojoules in snow-covered areas. The findings are supported by the Japan Meteorological Agency. According to the agency, the reflection rate of UV light on beaches is often between 10 and 25 percent, compared to 80 percent in lie new snow areas. The amount of light increased 4 percent with a 300-meter rise in height.

    Most of us know that UV rays can harm the skin. That's why we wear sunscreen on our skin before we get out in the suit. But many of us may not realize that UV rays are also harmful to the eyes.

    If your eyes are exposed to large amounts of UV radiation over a short period of time. You may experience a kind of sunburn of the eye, which is harmful. Your eyes will become red and feel a strange feeling. They may be sensitive to light. Fortunately, this is usually temporary and seldom causes permanent damage to the eyes.

    Long-term exposure to UV radiation, however, can be more serious. Scientific studies and researches have shown that exposure to small amounts of UV radiation over a period of many years increases chance of eye damage, which could lead to total blindness.

    January means it's time for coats and gloves and cold weather. While many of us are preparing ourselves for the cold weeks ahead, in some cities winter is the “hottest” season of all because it's the time for winter festivities.

    Every year 2 million people visit the Sapporo Snow Festival in Japan. This internationally well-known event began in 1950, when some local high-school students built six snow statues in Odori Park. Since then, the festival has grown to include lots of snow sculptures as well as a snow-sculpting contest that draws competitors from all over the world.

    In December, Finland created its 13th annual Snow Village, which will remain open until April, if weather permits. Snow Village lies nearly 200 kilometers north of the Arctic Circle. The village is designed by builders skilled in working with snow and ice. Visitors can take a tour of the village, eat in a restaurant made of ice or go dancing in the disco igloo(拱形圆顶小屋). They can also spend the night in a hotel made of snow. There's even an ice chapel(小礼拜堂) for couples who want to get married in Snow Village.

    Since 1935, the Fur Rendezvous has been held every February in Anchorage, Alaska, America's most northern state. Among the festival's many attractions is the World Championship Sled Dog Race, which draws sled dog teams from many countries. Dogs also take center stage in the Dog Weight Pull, in which dogs compete to see which one can pull the heaviest weight. The festival features sports like skiing, basketball, boxing and softball as well as the Grand Prix Auto Race in downtown Anchorage. True to the festival's name, there's also a fur auction(拍卖), where buyers buy real Alaskan furs. The first Fur Rendezvous lasted only three days. Now it's a 10-day event that attracts thousands of visitors.

    When I was a little girl, I remember that when my dad was repairing something, he would ask me to hold the hammer, so we would have time for a conversation with each other. I never saw my dad drinking or taking a night out. All he did after work was taking care of his family.

    I grew up and left home for college and since then, my dad had been calling me every Sunday morning. And when I bought a house several years later, my dad painted it by himself in the fierce summer heat. All he asked was to talk to him, but I was too busy in those days.

    Four years ago, my dad visited me. He spent many hours putting together a swing for my daughter. He asked me to have a talk with him, but I had to prepare for a trip that weekend.

    One Sunday morning we had a telephone talk as usual. I noticed that my dad had forgotten some things that we discussed lately. I was in a hurry, so our conversation was short. Several hours later that day I received a call. My father was in the hospital. Immediately I bought a plane ticket and on my way I was thinking about all the occasions I missed to have a talk with my dad. By the time I arrived at the hospital, my father had passed away. Now it was he who did not have time for a conversation with me. I realized how little I knew about my dad, his deepest thoughts and his dreams.

    After his death I learned much more about him and even more about myself. All he ever wanted was my time. And now he has all my attention every single day.

    Anyone wanting to throw away their mobile phone can do it in style（时尚地）and may even win a medal－at the Mobile Phone Throwing World Championship.

    Originally a local event in a small town close to the Russian border, the fifteenth annual contest drew many throwers from as far as Canada, Russia and Belgium.

    Founder Christine Lund describes the event as a good source of light exercise with an environmentally-friendly activity. "There are a lot of mobile phones on the second-hand market, and we are recycling them（before they become poisonous waste）," she said.

    The inventive Finns had already given the world the Sauna World Championships and the Wife Carrying Competition before coming up with a new way to make mobile phones even more mobile.

    This year's gold medal went to Finland's Lassi Etelatalo, who threw a waste Nokia unit a forceful 89.00 meters. "I prepared by javelin（标枪）throwing, I haven't really practiced throwing mobile phones,"Etelatalo said.

    Lund says competitors all have their favorite throwing brand. "People choose by size, by color or by how it fits in the hand……Some believe a heavy model will ensure a long throw, some want a light one."
