"How to Let Co of the World and Love All the Things Climate Can't Change" is the latest movie from film-maker and climate activist Josh Fox.The movie is the third film in a three-part series about climate change.

    In 2010,Fox's documentary "Gasland" was appointed for the highest award-an Oscar. "Gasland" explored the hotly debated process of removing natural gas from the ground.He examined the subject again in "Gasland Ⅱ".

    Fox was in Washington,D.C.recently to present his third film.He was arrested during a protest against a new fuel pipeline.In the film,Fox says pollution from fossil fuels must be reduced.Without limits,there will be more extreme weather,like severe storms and dry weather,rising sea levels,causing shortages of food and water, "When you really encounter that head on,it causes an in-credible crisis."

    In the new film,Fox travels through a sunless forest in the Amazon with local activists to measure oil spills.He goes to a village in Ecuador to learn how people there stopped a pipeline from being built.He joins young people in Australia to stop boats from entering the port of Newcastle.

    "You should probably know the downside of what we're about to do.This is the short list: drowning,being arrested: being run over by boats,drifting away in currents out into the Pacific Ocean,cultural disrespect,big waves."

    Also in the film,Fox talks to Ella Zhou,an energy expert.She explained the importance of what she calls "moral imagination"."I think that it forces us to get out of our box of thinking about,for instance,what is being successful.It allows us to have a moral value about what you want as a person.What do you want to do for the world and for yourself?"

    Tiny as they are, bats have the ability to “see” in the dark by using a special skill called echolocation(回声定位法). They make noises and wait for sound waves, or an echo, to bounce(反弹) back off objects. They can tell the distance of various objects by how quickly the sound waves bounce back off them. If no sound bounces back, they can then fly forward.

    This special ability has been simulated in the human world for a long time, such as in submarines and planes, whose sonar(声呐) systems are somewhat similar to echolocation. But apart from helping vehicles “see” where they are, what if blind people could use echolocation for themselves? It turns out, some already are.

    American Daniel Kish, who is blind, is known as “Batman”. This isn't because he walks around in a cape and a mask, but because he has a bat-like ability to locate where he is through sharp clicks he makes by moving his tongue against the roof of his mouth. Kish is so skilled at echolocating that he can ride a bike and hike on his own.

    Recently, research carried out at the University of Durham in England shed some light on the power of human echolocation.

    Kish worked with a group of scientists who studied the way blind people listen to the echoes that they produce from clicks.

    The team, which conducted experiments with other volunteers, found that people were capable of hearing even very faint echoes, ones far fainter than had been previously thought.

    Speaking to The Independent, Lore Thaler, lead scientist of the group, said, “We found that in some conditions, they were really faint – about 95 percent softer than the actual clicks, but the echolocators were still able to sense this.”

    Andrew Kolarik of the University of Cambridge is another expert in echolocation. Reacting to the Durham study, he told BBC News that echolocation “can be very useful at providing information at face or chest height” and could help people “avoid objects like low hanging branches that might not get detected by the cane or a guide dog”.

    Although Kish's skill is remarkable, there's hope for other blind people who want to use echolocation. According to BBC News, echolocation is a skill blind people can acquire and develop, just like learning a language. As Kolarik said: “Teaching echolocation skills could provide blind people with the means of exploring new places.”

    Did you know that Albert Einstein could not speak until he was four years old, and could not read until he was seven? His parents and teachers worried about his mental ability.

    Beethoven's music teacher said about him, "As a composer (作曲家) he is hopeless." What if this young boy had believed it?

    When Thomas Edison was a young boy, his teachers said he was so stupid that he could never learn anything. He once said, "I remember I used to never be able to get along at school. I was always at the foot of my class ... My father thought I was stupid, and I almost decided that I was a stupid person." What if young Thomas had believed what they said about him?

    When the sculptor (雕刻家) Auguste Rodin was young, he had difficulty learning to read and write. Today, we may say he had a learning disability. His father said of him, "I have an idiot (白痴) for a son." His uncle agreed. "He's uneducable," he said. What if Rodin had doubted his ability?

    Walt Disney was once fired by a newspaper editor because he was thought to have no "good ideas". Enrico Caruso was told by one music teacher, "You can't sing. You have no voice at all." And an editor told Louisa May Alcott that she was unable to write anything that would have popular appeal.

    What if these people had listened and become discouraged? Where would our world be without the music of Beethoven, the art of Rodin or the ideas of Albert Einstein and Walt Disney? As Oscar Levant once said, "It's not what you are but what you don't become that hurts."

    You have great potential. When you believe in all you can be, rather than all you cannot become, you will find your place on earth.

    We love the sea. We swim into it, live near it, build beside it, and even imagine about living under the sea. But we're terrified of it, too. For much of our history, we have turned to "hard engineering" to control the marine (海洋) environment and manage its influence on us. We build dams, sea walls and channels. But all these efforts seem to fail. The sea has a habit of taking back its own. And we suffer.

    Johnston, a marine ecologist, is advocating for "blue engineering" ­ the marine version of the "green engineering" movement on land that has seen nations like Singapore building the walls and roofs of the concrete jungle with plant life.

    We are expanding further into the marine environment. This practice does harm lo marine ecosystems. We're loving the sea to death, but we've not been thinking about design of structures (建筑物) with respect to ecology. Some coastal structures create shade, which reduces the growth of seaweed. Bright lights at night contuse species such as turtles. That's why blue engineering comes in.

    Throughout the world people are starting to turn things around. Researchers with the World Harbour Project are creating tiles (瓦片) similar to the natural structures found on rocky shores with 3D printing technology. These make more attractive homes for marine creatures. Researchers are also actively seeding these tiles with local seaweeds and creatures such as the Sydney rock oyster, which is particularly good at improving water quality. Twelve harbours around the world are taking part in this marine tile experiment, each working with their own unique marine life.

    It's a far cry from, he days when huge number, of old tyres were thrown, into the sea to build "artificial reef" (礁石). Those clumsy early attempts are now costing millions to remove, showing just how far we have yet to go in understanding how best to co-habit with the underwater world.

    In October 2013, Davion Only made an appeal on the Internet. He had learned that his biological mother had died not long before. "My name is Davion and I've been in foster care (寄养照管) since I was born," he said, "but I'm not giving up hope. "

    The heartbreaking appeal spread quickly, and Only's foster agency received calls from more than 10,000 people. Only ended up travelling to Ohio to live with a family. But after Only got into a physical fight with one of his elder would-be brothers, the family changed their minds.

     Back in Florida, Only passed through four different temporary homes over the following year, until he called Connie Going, his adoption case worker, to make a special request. Only had known Going for nearly ten years, and had asked every year if she would adopt him, but she always hesitated. "I always believed there was a better family than us out there," Going said in an interview. But last July, when Only called and asked again if she might adopt him, Going said something felt different. "When he asked me, my heart felt this ache and I just knew he was my son," she said.

     So Going, 52, invited Only to start spending time with the rest of her family-her two daughters, Sydney, 21, and Carly 17, and a son Taylor, 14, who she also adopted out of foster care. Eventually, after seeing how well the arrangement was working, Going, who had rented a bigger home, started adopting Only. Only moved in with her family last December. He officially joined Going's family on April 22, 2015 when the adoption papers went through.

    "Today, I feel blessed and honored to have been chosen to be the parent of all my children," Going said.

She is widely seen as proof that good looks can last forever. However, at over 500 years of age, time is catching up with the Mona____Lisa. 

The health of the famous picture, painted by Leonardo da Vinci in 1505, is getting worse year by year, according to the Louvre Museum where it is housed. 

"The thin, wooden panel(嵌板) on which the Mona Lisa is painted in oil has changed shape since experts checked it two years ago," the museum said. Visitors have noticed the changes but repairing the world's most famous painting is not easy. Experts are not sure about the materials the Italian artist used and their current chemical state.

 Nearly 6 million people go to see the Mona Lisa every year, and many are attracted by the mystery of her smile. "It is very interesting that when you're not looking at her, she seems to be smiling, and then you look at her and she stops," said Professor Margaret Livingstone of Harvard University. "It's because direct vision is excellent at picking up details, but less suitable to look at shadows. Da Vinci painted the smile in shadows."

 However, the actual history of the Mona Lisa is just as mysterious as the smile. Da Vinci himself loved it so much that he always carried it with him, until it was eventually sold to France's King Francis Ⅰ in 1519.

 In 1911, the painting was stolen from the Louvre by a former employee, who took it out of the museum and hid it in his coat. He said he planned to return it to Italy. The painting was sent back to France two years later.

 During World War Ⅱ, the French hid the painting in small towns to keep it out of the hands of German forces.

 Like many old ladies, the Mona Lisa has some interesting stories to tell.
