1 . During a waste collection session in May at the base of Mount Qomolangma, in the Tibet Autonomous Region, participants put garbage（mostly plastics）into bags and prepared to transport them downhill.
Dressed in camouflage and a blue vest, Samdrub dragged a sack to a blue truck parked a few hundred meters away. Scores of similar sacks were piled up along the roadside, waiting to be loaded onto the vehicle. Not far away, a couple of sheep roamed the deserted land looking for grass. “Loads of it here. Loads of it. This is the fifth consecutive time we have come here and we still haven’t finished the clean-up, ” said Samdrub, 64, who, like many Tibetans only uses one name. Samdrub and her companions are members of a regular clean-up campaign organized by the Lhasa Ban-White Association, an environmental advocacy group that taps the volunteer spirit to control abandoned plastic trash, also known as “white pollution”. The volunteers are of all ages and come from different walks of life. Now retired and with time to kill, Samdrub and her friends have taken to the city’s ravines and riverbanks to battle the pollution. “In recent years, I’ve read reports that livestock choked and died after eating plastic. I was born and raised in rural Shigatse, and I know how big a financial loss that is for herders. ” Samdrub said.
Tersing Dorji, 62, a member of the Lhasa Ban-White Association, said the worst pollution results from rural farmers’ markets and the common use of plastic bags, which are super-thin and relatively expensive to recycle. “They are of various colors and very light, and when the wind blows they fly everywhere. ” she said.
A rule was then implemented by authorities in Lhasa that banned the production of super-thin plastics and ordered retailers to charge customers a fee if they wanted a regular plastic bag. The ban was later extended to the entire region. It has worked well generally, especially in supermarkets and other large operations, where additional charges for plastic bags have prompted many shoppers to opt for reusable items, such as cloth bags.

2 . British sculptor Jason Taylor has made it his mission to use his talent to conserve our ecosystems by creating underwater museums. Over the years, the environmentalist has put over 850 massive artworks underwater worldwide. On February 1, 2021, Taylor launched his latest work — The Underwater Museum of Cannes.
―The main goal was to bring attention to the fact that our oceans need our help,‖ Taylor told Dezeen. ―Ocean ecology has been destroyed by human activity in the Mediterranean over the past few decades, and it is not obvious what is taking place when observing the sea from afar.‖
The Underwater Museum of Cannes contains 6 sculptures featuring local residents of various ages. They range from Maurice, an 80-year-old fisherman, to Anouk, a 9-year-old student. Towering over 6-feet-tall and weighing 10 tons, the faces are sectioned into two parts, with the outer part like a mask. The mask indicates that the world’s oceans appear powerful and unbeatable from the surface but house an ecosystem that is extremely fragile to careless human activities.
Though the waters surrounding the sculptures now appear a pristine blue, the seabed was filled with old boat engines, pipes, and other human-made trash when the project began about four years ago. Besides removing the trash, Taylor also restored the area’s sea grass. Just one square meter of the sea grass can generate up to 10 liters of oxygen daily. The sea grass also helps prevent coastal erosion and provides habitats for many ocean creatures.
―The idea of creating an underwater museum was to draw more people underwater and develop a sense of care and protection,‖ Taylor told Dezeen. ―If we threw unwanted waste near a forest, there would be a public outcry. But this is happening every day in our surrounding waters and it largely goes unnoticed.

3 . High on the Qinghai-Tibet plateau lies China’s “Water tower” Sanjiangyuan.
Sanjiangyuan National Park is a model of eco-protection.
The idea of a national park system is still new in China, but it must be realized. As President Xi wrote in the congratulatory letter to the forum, “Building an ecological civilization bears great significance in the development and progress of human civilization.” With great efforts, people may one day be able to enjoy themselves in the vast lands of Sanjiangyuan and run freely across the plains alongside nature’s animals.

| C．Unfortunately, the situation has got worse and worse. |
| D．It attracts visitors with its fantastic nature beauty and various wildlife. |
| E．The park has increased the area’s green coverage and attracted more wildlife. |
| F．Hopefully, the success of Sanjiangyuan will mark the start of a greener future. |
| G．The local government has different ways of slowing environmental damage. |
4 . Throughout history, humanity has existed side-by-side with viruses and bacteria. From the bubonic plague to smallpox, humanity has evolved to resist these bacteria and viruses. However, there are now new ways for them to infect us.
Climate change is melting permafrost(冻土) areas that have been frozen for thousands of years. As the permafrost melts, so too the ancient bacteria and viruses that have been frozen. These ancient bacteria and viruses, which previously lay inactive in the ice, may spring back to life as the earth’s climate warms.
In August 2016, a 12-year-old boy in the Arctic Circle died and at least twenty people there were hospitalized after having been infected by anthrax(炭疽).
Experts studied and concluded that over 75 years ago, a reindeer infected with anthrax died and its body was frozen and trapped under a layer of permafrost. It stayed there, with the disease inactive, until a heatwave in the summer of 2016. The heatwave melted the permafrost and exposed the reindeer body, which then released the infectious pathogen(病原体) into the nearby water and soil, and then into the food supply. More than 2,000 reindeer feeding near the body became infected, which then led to a small number of human cases.
While you may think the incident is isolated to that area, the fact that long-inactive viruses and bacteria might wake up soon due to climate change will affect us all. Pathogenic viruses might be preserved in old permafrost layers, including some that have caused global epidemics in the past.
With climate change, who knows what deadly viruses and bacteria hidden beneath permafrost areas are threatening us. Perhaps it is time for everyone to do their part to stop global warming.

7 . Along the Ring of Fire
Off the coast of Alaska, the lava rises through cracks (裂缝) at the bottom of the Pacific Ocean. It flows like toothpaste pressed from a tube. Spreading and erupting, the earth slowly builds a new island.
Along the Pacific coast of South America, one part of the earth’s surface gradually moves toward another. Although difficult to believe, the rocky outer surface of Earth is not solid; rather, it is broken up into huge pieces called plates(板块).
These things take place thousands of miles apart, yet they are connected. Surrounding the Pacific Ocean is a circle of volcanoes that includes more than half of the world’s active volcanoes.
The Ring of Fire spreads from the west coast of South America northward to Alaska. It goes left at the Aleutian Islands and crosses the Pacific Ocean. Then it heads down the east coast of Asia toward New Zealand.
Some volcanoes erupt more quietly, with lava flowing through the cracks in Earth’s surface. This type of volcano is found in Hawaii.
| A．This area is called the Ring of Fire |
| B．Although the plates are connected |
| C．As the plates move past one another |
| D．The Ring of Fire is also where most earthquakes happen |
| E．Major volcanic eruptions along the Ring of Fire make history |
| F．In 1991 Mount Pinatubo in the Philippines erupted after 600 quiet years |
| G．Lava from a volcano tends to advance slowly but still causes great damage |
8 . A day in the clouds
The air is thin and we have to rest several times on the short hike(徒步旅行)from camp. To our left, snow-covered mountains disappear into clouds that seem almost close enough to touch. On the plain(平原) in front of us, we can just make out a herd of graceful animals. This is why we stay here.
Tibetan antelopes live mainly on the plains of Tibet. Watching them move slowly across the green grass, I'm struck by their beauty. I'm also reminded of the danger they are in. They are being hunted, illegally, for their valuable fur.
My guide is Zhaxi, a villager from Changtang. He works at the Changtang Nationa Nature Reserve(保护区) . The reserve is a safe place for the animals and plants of northwestern Tibet. To Zhaxi, protecting(保护)the wildlife is a way of life. "We're not trying to save the animals." he says. "Actually, we're trying to save ourselves."
In the 1980s and 1990s the population of Tibetan antelopes dropped by more than 50 Percent. Hunters were shooting antelopes to make money. Their Living places were becoming smaller as new roads and railways were built.
In order to save Tibetan antelopes, the Chinese government placed them under national protection. Zhaxi and Volunteers watched over the antelopes day and night to keep them safe from attacks. Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains.
The measures were effective. The antelope population has recovered and in June 2015, the Tibetan antelope was removed from the endangered species list(濒危物种名单). The government, however, does not intend to stop the protection programmes, since the threats(威胁) to the Tibetan antelope have not yet disappeared. Only when we learn to exist in harmony with nature can we stop being a threat to wildlife and to our planet.
