The poaching（偷猎）, or illegal killing, of rhinos(犀牛) in South Africa is growing worse each year．The government recently reported that a record number of rhinos were poached in 2015，a year which had more rhino killings in South Africa than ever before.

    The World Wildlife Fund，or WWF，says about 20, 000 rhinos live in South Africa．That is more than 80 percent of the rhinos in the world．Edna Molewa，South Africa's Environment Minister，says, “During 2015，we are sad to say this，1,215 rhinos were killed．This is a rise in the number of poached rhinos from 1,004 in 2014 and indeed very worrying.”

    The animals are hunted for their horns(角)．Many people in Asia believe the horn has curing power，which drives poachers， at all costs，mad for more horns． But there is no scientific evidence for this belief．The horn is made of keratin(角蛋白)．That is the same thing as human hair，fingernails and toenails.

    Ms．Molewa said 386 suspected poachers were arrested last year，an increase from the year before．But rhino protection workers say poachers often go unpunished after arrest． South Africa's legal system is ineffective． Ms． Mo1ewa said more needs to be done and South Africa is taking strong measures to protect rhinos．The efforts include moving some of the animals to secret places in neighboring countries. “Now approximately 100 rhinos have been moved to neighboring states in the SADC region during 2015 and 200 more rhinos will be moved this year,” Molewa said.

    Jo Shaw，the rhino program manager at the WWF，said， “We're talking about a loss of a hundred rhinos a month，or more than three a day．We really need to see effective action not just at a national level but internationally．” She says officials should find the criminal groups responsible for the poaching and punish them. Government officials are to meet in Botswana in March at the Inter-governmental Conference on Illegal Wildlife Trade.

    A new phone app uses shaking from smartphones to warn people about earthquakes. The new app is called MyShake, which is the work of four researchers at the University of California. Berkeley.

    Smartphones are equipped with accelerometers(加速器). MyShake uses phone accelerometers to measure seismic (地震的) activity. It has been programmed to know the difference between normal activity and earthquake movement. The software developers say their app is right 93 percent of the time. A smartphone sends seismic information to the app developers. If the developers receive several warnings from one area, it recognizes that an earthquake may be taking place or will take place soon. Using information sent from the app, the network then judges the location and strength of the quake in real time. MyShake can record 5.0 earthquake at distances of 10 kilometers or less.

    MyShake uses very little power, according to its developers. Only when seismic activity is sensed by the app does it become active and sends data to the network. The app works best when your phone is resting on a flat surface, like a table.

    The developers hope that MyShake can add to information collected by the U.S Geological Survey. That U.S agency has created the Earthquake Early Warning System, also known as the EEW. The EEW has used sensors for measuring quakes in many areas. In places where no such equipment exists, MyShake may be the only method of early quake detection (发现). The app also shows ways to stay safer during an earthquake. The developers say it will become more effective as more people use it.

    The developers say they hope to add a feature that will warn people about possible tsunami after an earthquake.

    Two of the saddest words in the English language are “if only”. I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.

    My father is famous in our family for saying “Take the extra minute to do it right”. I always try to live by the “extra minute” rule.  When my children were young and likely to cause accidents, I always thought about what I could do to avoid an “if only” moment，whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫)onto the sharp corners of a glass coffee table.

    I don't only avoid those “if only” moments when it comes to safety. It's equally important to avoid “if only” in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say “I love you“ or “I forgive you”. When my father announced he was going to the eye doctor across from my office on Good Friday，I told him that it was a holiday for my company and I wouldn't be here. But then I thought about the fact that he's 84 years old and I realized that I shouldn't give up an opportunity to see him.  I called him and told him I had decided to go to work on my day off after all.

    I know there will still be occasions when I have to say “ if only” about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I'm doing the right thing. I'm buying myself peace of mind and that's the best kind of insurance for my emotional well-being.

    At some point in life, many people suffer a mental problem. While most people get over it, for others it doesn't go away easily.

    The World Health Organization (WHO) says that about 20 percent of children and teenagers across the globe suffer from mental illness. It's thought that the number of children and teenagers with mental illness around the world will increase by half by 2020. It will become one of the main causes of disease, disabilities and even death.

The reason for mental problems among young people may be the increasing pressure in life. Study and relationships have always caused huge stresses for school children. For instance, they experience school bullying(欺凌)and academic pressure.

    In China, the picture isn't bright, either. About 30 million Chinese children and teenagers under the age of 17, or 10 percent of children and teenagers in China, have a mental health challenge, reported China Daily.

    Also, according to China Daily, Chinese people don't seek help with their mental problems. They fear that others will think less of them if they admit that they are in trouble. Many Chinese people are ashamed of their mental problems and mental illness is taboo(禁忌)in any Chinese families.

    In the UK, over three-quarters of young people believe their mental health problems have a social shame and a quarter of young UK people wouldn't ask for help if they developed a mental problem.

    Young people who don't seek help for their condition may be creating problems for themselves in the future. If you feel something is wrong within you – seek help.

Feeling down? Here are three things to try if you feel low.

    Go to a psychology teacher. The teacher will listen to you and offer help – for free!

    Call 800-810-1100. It's the number of a hotline run by the Mental Health Research and Prevention Center. The line is open 24 hours a day.

    Tell your parents and visit the hospital if the situation gets out of control.

    It was dinner time for the Rangers, a group of mostly Indigenous (本地的) Australians who had spent a long day cleaning up the polluted beaches of the continent's northern coast. Soon they would be eating freshly caught fish and seafood cooked under the stars on an open fire, as their ancestors did.

    The Rangers are of more than 100 Indigenous groups spread across Australia who have taken on the job of protecting the land of their forefathers. In Arnhem Land, they are the protectors of 3,300 square miles of land and sea. They comb the beaches by hand, picking up as much rubbish as possible. The task is very difficult as each day it delivers waves of new rubbish.

    For the Rangers, cleaning the beaches is more than a vacation. For a people whose culture is strongly tied to the land, protecting the environment is equal to preserving their history.

    However, colonization forcefully broke their connection to the land generations ago. Indigenous people were displaced and their cultural practices outlawed. Tens of thousands of years of traditional land management ended, and as a result many parts of the country now face serious disasters from invasive plant and animal species, bush fires and land mismanagement.

    In recent years, the government has restored more than 20 percent of Australia's land to Indigenous owners. Since 2007, the Indigenous Rangers Organizations have been at work protecting this land.

    Luck, one of the few non-Indigenous employees working with the Rangers, said the combination of old and new techniques and an appreciation for the culture of Indigenous workers has been critical to the program's success.

    "You are working with staff who see the world different to you, so there is a much higher focus on the cultural aspects of work and life," he said.

    "Being a ranger is a source of confidence. You feel strong," said Terence, a senior ranger. "Here we still live on the land. The culture is still alive."

The journey to discover myself，care for myself and love myself has been a long one.But，it's been a journey that has finally saved my life.

I remember throwing up for the first time when I was 8 years old.Somehow I had developed the belief that being thin was the only way to be accepted and loved.This way of thinking intensified（加剧） as I got older and bulimia（神经性贪食）became more and more deeply rooted in my life.

When I was 15 years old my family said goodbye to everything we had ever known and boarded the plane for New Zealand.I felt alone and scared in a world that was completely different to anything I had ever known.Eating helped numb（麻木）my pain and throwing up helped keep me thin.

By the time I went to university I was throwing up over 15 times a day.I was so ashamed of what I had become.

Although my bulimia had completely turned my life upside down，I knew one thing for sure that I loved my family more than anything in the world.This belief eventually made me pick up the phone and book my first appointment with a therapist（治疗专家）.

The first session I had with my therapist，Amanda，was amazing.I walked out of her office feeling like I had finally done something positive for myself Amanda made me realize that I wasn't alone in my suffering and there were thousands upon thousands of girls just like me.

I met regularly with Amanda for the best part of a year，over which time I learnt how to treat myself kindly，respect myself and love myself.I said goodbye to bulimia after over a decade of suffering.

Just turn to face the direction of self﹣discovery，self﹣love and self﹣acceptance and keep walking until you get there.It will be the journey of a lifetime.
