Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That's why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.

    Years ago, over hunting and the ivory trade were the biggest threats to elephants survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.

    The 21st century brings a different challenge to elephant conservation —land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.

    Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.

    AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.

    The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.

    Those who are used to looking through thousands of books in big bookstores may find Japan's Morioka Shoten a little strange. That's because this tiny bookstore that is located in Ginza, Tokyo sells only a single book at a time.

    Opened in May 2015, Morioka Shoten is the brainchild of Yoshiyuki Morioka. The experienced bookseller began his career as a bookstore clerk in Tokyo's Kanda district before branching out to open his own store. It was here while organizing book readings that he realized that customers usually came into the store with one title in mind. Morioka began to wonder if a store could exist by selling many copies of just one single book. In November 2014, he partnered with his two friends, to establish a unique bookstore with the idea of “A Single Room, A Single Book.”

    Like its offering, the bookstore is simple. The selections that are picked by Morioka change weekly and vary widely to attract customers with different interests. Recent choices include The True Deceiver, an award-winning Swedish novel by Tove Jansson, Hans Christian Andersen's Fairy Tales, and a collection of artist Karl Blossfeldt's photography of plants. Morioka has also chosen books written by famous Japanese authors Mimei Ogawa and Akito Akagi.

    To highlight his only offering, Morioka often uses clever methods. For example，when selling a book about flowers, he decorated his shop with the ones that had been mentioned in the book. He also encourages authors to hold talks and discussions so they can connect with customers. Morioka says his goal is for the customers to experience being inside a book, not just a bookstore!

    Risky as the idea might seem, things appear to be going well. Morioka says he has sold over 2,100 books since he opened it. Things can get better considering that (考虑到) his bookstore is becoming increasingly popular not just among the locals but also visitors from other countries.

    For hours after their boat sank, Ken Henderson and Coen trod(踏) water in the Gulf of Mexico, talking about life and death while struggling to survive. For more than 30 hours, it worked.

Then Henderson was forced to make a decision. "I'm going to go for help or you're not going to make it," Henderson told Coen, just before cutting the strap(带子) that connected them in the deep, cold waters. "I understand,"Coen responded, giving Henderson a last set of instructions, "Kiss my babies for me."

    Days after the fishing trip ended in tragedy, Henderson told the story for The Associated Press.

    They had been fishing for a few hours when suddenly Coen noticed the boat was filling with water. Henderson got both motors roaring, only to have the saltwater that had leaked in break them straight away…Coen jumped to the right, his sunglasses and cap flying off. The two grabbed extra life jackets and other floating items, including a half full bottle of Diet Coke.

"The water was so cold and it took your breath away," Henderson said. They immediately began to tremble.

    The pair prepared for a long wait. And they talked.

"We discussed things and discussed life. We discussed families. We just tried to keep occupied," Henderson said.

    Eventually Coen started hallucinating(有幻觉). Henderson tried to keep Coen's arms and legs moving. But as morning came, Coen's situation worsened. And so Henderson decided to cut the strap.

    He swam for two hours, tired, frustrated and depressed. Then he saw an oil rig(钻探平台) in the distance. He swam, seeing ice and crystal trees in the water. He reminded himself constantly there were no trees.

    His legs was so weak that he could barely lift them. Henderson slowly pulled himself up the rig's ladder.

    It was over 50 miles from where they had gone in the water.

    All he could think of was Coen. Convinced his friend would survive, he told the coast guard where they had parted.

    Two hours later, a fisherman found a body in a life jacket.

    Later, in the hospital, Henderson saw his friend. He apologized and asked for forgiveness. He promised to realize his wishes and look after his girls.

"I felt like a part of me had died out there," Henderson said.

    Ms. O'grady, the head of Britains Trades Union Congress, issued a challenge on September 10th. "We can win a four-day working week, "she told members. The demand is far from new. Shorter working weeks have been tried in New Zealand and Sweden, wherein happier, healthier and more motivated employees. Those who work shorter weeks are also reported to be more productive. Should weekends, therefore, be lengthened?

    France's experience suggests workers may not leap at the chance of working for fewer hours. The government reduced the full-time workers week to 35 hours in 2000. Last year the French worked 38.9 hours a week on average, seeming happy to labor above the required level and pocket the extra pay or holiday allowance.

    And businesses may not seize the opportunity either. Working less may be linked to higher productivity (on a per-hour basis), but overall output could still fall because of the smaller number of hours worked. That will not get governments or employers excited.

    Advocates of a four-day week could claim that improving people's quality of life is more important than boosting the economy. In an essay published during The Great Depression, John Maynard Keynes wrote of an "age of leisure and abundance" in which technological advances would allow people to work 15-hour week.

    Unfortunately for any readers working hard on a Friday afternoon, Keynes jumped at his conclusion too soon. Even Ms. O'grady, now demanding a longer weekend, is pessimistic in her timescale. A four-day week is apparently achievable “in this century”.

We are all stuck in the thought of having satisfying relationships, which bring some meaning to our lives and make us happy. We are so busy in finding true happiness that we often forget true happiness lies within us.

You have to love yourself first in order to love someone else. We have heard in countless inspiring speeches that self-love is the basis of a happy life. Have you ever wondered that with so many people advertising self-love, why haven't we been able to love ourselves?

One of the reasons for our failure to love ourselves is that we have been taught to be selfless from the start of time. The minute we start thinking about ourselves, everyone around us makes it their personal mission to remind us of how selfish we are. However, there is nothing wrong with putting your needs and yourself first. Self-love is not selfish. It only helps us better understand which sacrifices (牺牲) are worth making!

Actually, self-love and healthy relationships cannot be separated. Self-love is the very core of any healthy relationship. Now you might wonder how my love for myself is going to make me able to have a healthy relationship. Isn't a healthy relationship all about giving? Honestly, No.

When you know your worth, you know what you are willing to accept in a relationship and what not. You will know where to draw boundaries because you value your own opinions. You will have a clear understanding of what you need, what are your values and your limits. From now on, you should realize that true happiness lies within you and you shouldn't waste time and effort searching for peace and joy in the world outside.
