2 . In the summer of 2021, the Pacific Northwest experienced a severe heatwave that caused widespread panic and destruction. Temperatures reached record levels, including 114℉ in Portland.
A heatwave, born over the Pacific, drifted inland and grew in intensity, creating a heat dome. Ice was the first victim, and as snowpacks melted, glaciers released fast flowing muddy water that flooded towns. Salmon, sensing the water temperature change, began migrating early. But then they struggled to breathe as the rivers warmed. Vegetation was next—unable to escape the heat, it struggled to hold water. Bighorn sheep moved to higher ground, doves panted like dogs, baby eagles jumped to their deaths in an attempt to fly to escape overheating with their siblings.
In 72 hours, the official number of human deaths was 1,000—but the actual number is likely higher, especially among the elderly, poor, and medically vulnerable. The town of Lytton, British Columbia was burned down when temperatures there hit 121℉. Over a billion sea creatures met their deaths over the three days.
Such a heatwave in the Pacific Northwest had been thought to be as likely as snow in the Sahara. But then it happened. Right now, scientists can’t predict where or when such heat will appear next, but they do know that occurrences such as this are a direct result of human activities. As fossil-fuel burning increases levels of heat-trapping gases like carbon dioxide, the planet warms. Heat is the prime mover of climate chaos, melting ice, . drying soil, , and even reviving ancient bacteria from thawed permafrost (永冻土解冻).
Humans might be able to engineer their way out of anything—cities like Los Angeles and Paris are already working to deflect (使偏斜) sunlight and have more shade trees. But there are limits to adaptation for Earth’s population of nearly 8 billion. Parts of the Middle East and South Asia are already too hot for humans in summer.

3 . Our ship sailed on the sea into the Earth’s night. Here, there was no visible light from the Sun or the Earth Engines. But as we looked up, we children saw the starry sky for the first time in our lives. How breathtakingly beautiful it was!
Ms Xing put an arm around us while pointing at the sky with her other hand. “Look, children! That is Proxima Centauri (比邻星), our new home!” With these words, tears ran slowly down her face. Before long, we were all in tears—even the captain and crew. We all looked in the direction that Ms Xing was pointing. There was only one point of light among the twinkling stars that shined constantly: Proxima Centauri—the only source of hope and comfort for a hundred future generations. “Whatever risks we might take, we will finally make it there!” said the captain, in an assured voice.
On our way back from the sea, we saw the first sign that Earth had begun its journey. In the night sky, a huge comet had appeared. It was the Moon, abandoned by humankind. Lunar Engines had been installed to the Moon to force it out of its orbit so that a disastrous crash could be avoided as the Earth sped up and moved away. As it progressed, the gravitational tide of the Moon caused the ocean to swell, creating gigantic waves. We quickly got off the ship to our destination in the Southern Hemisphere. The next few days were the countdown to our departure.
Finally came the big day! As Earth Engines was set at a full power, we got immediately blinded by the bright light from it. This acceleration created massive tsunamis hundreds of meters high that crashed onto the coasts of every continent. Burning hot hurricanes roared through the boiling waves, screaming with wild fury and pulling up almost every tree on Earth.
Our Earth, with its blue tail cutting through the darkness of space, had set out on its long journey, and with it went all of humankind.

5 . As a young girl growing up in France, Sarah Toumi dreamed of becoming a leader who could make the world a better place. Her passion to help others was awakened when, from the age of nine, she accompanied her Tunisian father to his birthplace in the east of the country during holidays. There she organized homework clubs and activities for children.
Toumi witnessed first-hand the destructive effect of desertification. “Within 10 years rich farmers became worse off, and 10 years from now they will be poor. I wanted to stop the Sahara Desert in its tracks.” A decrease in average rainfall and an increase in the severity of droughts (干旱) have led to an estimated 75 percent of Tunisia’s agricultural lands being threatened by desertification.
Toumi recognized that farming practices needed to change. She is confident that small land areas can bring large returns if farmers are able to adapt by planting sustainable crops, using new technologies for water treatment and focusing on natural products and fertilisers (肥料) rather than chemicals.
In 2012, Toumi consolidated her dream to fight the desert. She moved to Tunisia, and set up a programme named Acacias for All to put her sustainable farming philosophy into action. “I want to show young people in rural areas that they can create opportunities where they are. Nobody is better able to understand the impact of desertification and climate change than somebody who is living with no access to water.”
By September 2016, more than 130, 00 acacia trees had been planted on 20 pilot farms, with farmers recording a 60 per cent survival rate. Toumi estimates that some 3 million acacia trees are needed to protect Tunisia’s farmland. She expects to plant 1 million trees by 2018. In the next couple of years, Toumi hopes to extend the programme to Algeria and Morocco.

8 . Shane Grammer’s artwork can be found in cities in Mexico, South Korea, Dubai and beyond.In the past years, it’s the murals (壁画) he painted on damaged walls throughout the town of Paradise, California that have gained attention and touched viewers.
In 2018, the Camp Fire, the deadliest wildfire in California’s history, swept through Paradise, flattening entire communities, killing scores of people, and displacing tens of thousands. Grammer,whose hometown was just 15 miles from Paradise, was living with his family and working in the Los Angeles area when he saw accounts of the destruction on his friends’ social media pages. A single mother he knew shared a photo of ash and rubble where her home once stood. A childhood friend’s post showed her burned-down house. After he saw a photo of a friend Shane Edwards’ home, which had been reduced to a brick wall with only a chimney standing, he was driven to paint it.
With Edward’s permission, Grammer then used spray paint to transform Edwards’ burnt chimney into a strikingly black-and-white portrait of a woman, a piece he called “Beauty Among the Ashes.” Once the image was posted on Instagram, the victims of the fire, especially, could not contain themselves. “You bring beauty and hope.” one posted. Over three months, the 47-year-old created a series of more than a dozen spray-painted murals on the remains of buildings and vehicles rendered useless by the flames. The images included a victim of the fire, a young girl who survived but lost her house, and a series of religious characters.
As a street artist, Grammer has committed his life to creating more art installations (装置艺术) all over the world that connect people through tragic life events. He has started a foundation called the Art Through Hope Foundation where he intends to bring peace through his art to those affected by tragedy. “I want to do something powerful and make art that emotionally influences people,” said Grammer in an interview with KRCR. “I think any artist would consider that as their ultimate goal. And to me, that is the biggest miracle I feel like.”

9 . Boracay, Philippines
Boracay is a tiny island and its main attraction is “White Beach”, a perfect postcard white sand beach surrounded by palm trees, dive shops, bars and restaurants. Our favourite seat to enjoy the sunset is “Diniwid Beach” located to the north of White Beach. After the perfect sunset, choose a bar to enjoy live music and party all night long.
Santorini, Greece
Santorini offers a unique landscape of beaches in exotic (异国的) colors of black, red and white, a product of volcanic sand. Imagine swimming in the warm mythic Aegean sea, with volcano and sunsets as a background. The island architecture is very distinctive, churches are built into caves and the whitewashed
houses, blue-domed churches and paved paths are astonishingly beautiful.
Lofoten Island, Norway
The Lofoten Islands are a wonderful sight indeed. With deep bays and splendid mountains, this is a wilderness unequalled in its beauty, where giant sea eagles soar. Milder in climate than their position suggests, visitors are attracted to the islands to experience the Northern Lights and Midnight Sun.
Saint John Island, Caribbean
Life moves at a slower pace here, where wildlife abounds (大量存在). The National Park dominates here, covering more than half of the island. It is just nine miles from one end to the other and with countless bird species to spot and dolphins in the warm Caribbean waters, it's no surprise that this is a destination that draws nature lovers. This is a place to rest and relax.

10 . Jaw-dropping architecture isn’t new. We’re still fascinated by the Great Pyramid built 4,500 years ago! Read for more recent examples of innovative buildings constructed using modern technology.
Crooked House (Poland)
COMPLETED: 2004
With its curved (弯曲的) walls and roof, it is popular with photographers. However, staring at it for too long might make you dizzy! Inside is a typical mall and office building. A favorite feature is the Wall of Fame, with signatures from Polish celebrities (名人). It’s modeled after the Hollywood Walk of Fame.
Cube Houses (Netherlands)
COMPLETED: 1984
The Cube Houses are a popular attraction, but they are also real houses that people live in! The furniture is tailor-made to fit the strange angles where the walls meet. Architect Piet Blom designed the homes based on the idea of “living as an urban roof,” with the housing above and the courtyards, shops, and even a chess museum below.
Wonder Works (US)
COMPLETED: 2006
Looking at the cracks in this building, you might think, is it about to collapse? But it’s all an illusion (幻觉). This indoor amusement park is actually pretty normal. The upside-down features are just for show. Inside are more than hands-on science exhibits and activities, including a laser-tag zone and a hurricane-force wind tunnel!
Guangzhou Opera House (China)
COMPLETED: 2010
It was designed by Iraqi-born architect Zaha Hadid. She said she let natural places inspire her buildings, such as this opera house on the Pearl River. She used latest construction and design methods to make her design a reality. GPS positioning and laser techniques helped shape the structure, which includes tons of steel and glass.
