Every year gray whales swim a 10,000 miles round-trip, from the cold waters near Alaska, down the coast of North America to the warm waters near Mexico, and back again. It is one of the longest migrations (迁徙) of any mammal (哺乳动物).

    All day, all summer long, in the cold waters near Alaska, gray whales eat and eat.

    Instead of teeth, gray whales have baleen (鲸须) they use to get food from ocean water. They get big mouthfuls of muck (淤泥) from the ocean floor, then push that muck right back out through their baleen. The mucky water flows through, but tiny animals get trapped in the baleen and licked up.

    When the water starts to freeze, the whales begin their long trip south. They swim night and day, without stopping to eat or rest. During the long journey, migrating whales may push their heads out of the water to see where they are.

    Two months later, the whales reach Mexico. Babies are born here in warm, shallow (浅的) waters called lagoons (濒海湖). Ocean lagoons have no food for the adults, but the babies are safer here than in the open seas. All winter the babies grow big and strong.

    In spring first the dads and teenagers leave the lagoons, then the moms with babies. Migrating gray whales swim close to shore, especially moms with babies. The ice is melting up (融化) north, and it's time for the hungry whales to make the long journey back to their summer feeding grounds.

    We arrived at the hospital to find Dad was very weak, but his smile was as sure as ever. It was another attack of pneumonia(肺炎). My husband and I stayed with him for the weekend but had to return to our jobs on Monday. Local relatives would help Dad get home from the hospital and look after him. But I longed to be able to let him know that we cared too, even when we weren't with him.

    Then I remember a family tradition when our children were small. When leaving their grandparents' home after a visit, each child would write a note to their grandparents. They hid notes in the cereal(麦片), under a hairbrush, next to the phone or even in the microwave oven. For days, their parents would smile as they discovered these signs of our love.

    So as I tidied Dad's kitchen and made up a bed for him downstairs in the living room, I wrote some notes. Some were practical, "Dad, I put the food in the fridge so it wouldn't spoil." Some expressed my love, "Dad I hope you will sleep well in your new bed." Most notes were downstairs where he would stay for several weeks until he recovered strength, but one note I hid upstairs under his pillow, "Dad, if you have found this one, you must be feeling better. We are so glad. "

    Just like his medicine strengthened him physically, these "emotional vitamins" would improve his spiritual health. Several weeks later, in one of our regular phone calls, I asked Dad how he was doing. He said, "Pretty good. I just found your note under my pillow upstairs!"

    Mew Zealand's chief conservation (环保)officer，Lou Sanson, caused an argument in October suggesting that it should be time to start charging tourists for entering national parks. New Zealanders are keen fans of these parks. Many would be annoyed at having to pay. But many also worry about the incoming foreign tourists who have been seeking the same fun.

    In 2016 New Zealand hosted 3.5m tourists from overseas; by 2022 more than 4.5m are expected every year—about the same as the country's population. Tourism has become the biggest export. The national parks, which make up about one-third of the country, are a huge draw. About half of the foreign tourists visit one. They are keen to experience the natural beauty promised by the country's “100% Pure New Zealand” advertising campaign (and shown off in the film adaptations of “The Lord of the Rings” and “The Hobbit”，which were shot in New Zealand's breath-taking wilderness).

    But for every happy foreign couple posing for a selfie next to a tuatara (楔齿蜥)there is a NewZealander who remembers the way things used to be-when you could walk the tracks without running into crowds at every clearing. Many locals now wonder why their taxes, as they see it, are paying for someone else's holiday. Mr. Sanson would seem to agree. Entry fees could be used to upgrade facilities such as car parks and trails. A charge could also help reduce numbers at some of the popular locations by making it cheaper to use lesser-known, but no less beautiful, trails far away from home.

    Some are not so sure it would work. Hugh Logan, a former chief of conservation for the government who now runs a mountain climbing club, worries it would cost too much to employ staff to take money from hikers at entrances. It would also be difficult to prevent tourists from entering the parks without paying.

    Some argue that it would be easier to charge visitors a “conservation tax” when they enter the The Green Party the third-largest in parliament says that adding around NZ$18($12.50)is still acceptable to foreign tourists. But some travel companies don't quite agree with the idea. They note that tourists already contribute around NZ $l.l bn through the country's 15% sales fetter, such firms say, to use foreign tourists' contribution to this tax for the protection of the parks.

    Among the fiercest critics of a charge are those who point out that free access to wilderness areas is an important principle for New Zealanders, It is documented in a National Parks Act (法案) which inspires almost constitution-like devotion among the country's nature-lovers. Mr. Sans on has a rocky path ahead.

    Have you ever thought that your life will be perfect if something in your outside world changes? You may say, "I will live happily if I find my soul mate." You may say, "If the perfect job comes along, I will get satisfaction. My problem is that my boss is stupid." Or you may say, "If I have a child, I will know what it is like to be loved." The problem is that it is not the outside world that prevents you from experiencing peace, love and joy. Instead, it is your own internal (内部的) patterns that get in your way.

    To prove this point, at my weekend programs, I had my students look at a flower on my table. Then I asked them to share their experiences. Some showed a state of complete joy because staring at the flower reminded them of their wedding or a great trip with their lovers. Others said the flower made them angry because it reminded them of a gift given by a former partner who turned against them. Some students even told me that the flower reminded them of their beloved grandmothers' gardens with some shedding tears (流泪)of joy and others shedding tears of sadness. However, the flower was still just a flower.

    Our internal patterns decide whether each moment is filled with peace, anger, joy, love or sadness. When you don't realize that it is your own internal state that is creating your experience, you are likely to blame (责备)the external situations in your life. Most people aren't taught that emotion is a choice. And they aren't taught how to change those lower emotional patterns such as anger, anxiety, sadness and so on. Next time, when you meet something bad, please look at your internal state. When you accept that you are responsible for your own state, and find the courage to turn inward, you can step out of being a slave to what shows up in your external world.

    According to the International Ecotourism Society, eco-travel is "responsible travel to natural areas that protects the environment, maintains the well-beings and involves education". Eco-travel is on the rise, as more and more people become conscious about their carbon footprint.

    Expert from Boundless Journeys, Matt Holmes, who works-on travel experiences towards conserving areas said, "As scientists and non-scientists learn more about how we human beings are impacting the planet, I think more people want to do what they can while still exploring the world. Our guests are definitely interested in that aspect of our journeys. Travelers can farm their own food in Italy, managing their use of water and using solar or wind power. They can also visit n family-run camp that cares for retired logging elephants in Myanmar, know a park entry fee goes to a conservation organization in Costa Rica, employ and train members of the local community or partner with a protection group. There are lots of options for seeking out greener holiday."

    Most people believe that eco-travel is expensive and it is true. Matt explained "Anti-poaching patrols (巡逻) need to be paid, solar energy equipment costs a lot to install, building with environmentally friendly, materials is more expensive and so on. The extra cost is necessary, as you're paying to minimize your footprint and protect the places you visit, which is exactly what eco-travel is about. The financial success and sustainability (可持续性) of an eco- focused operation doesn't come from thin air." The industry is trying to make eco-travel affordable and make it accessible to the common people.
