【推荐1】At the age of 16, Julia Butterfly Hill quit school and worked at a restaurant. For many years, she was only interested in making money and material things. Then one day she had a serious car accident, which changed her life. Hill said: “I realized I wanted to find a more powerful purpose for being here on this planet.”
As soon as she recovered, Hill traveled to California. There she saw ancient redwood trees, which are the largest trees in the whole world. The wood from redwood trunks is very hard. So the Pacific Lumber Company cut down many of the huge redwoods to use for construction. There are not many forests of these trees left. Many environmental activists want to protect the remaining trees. The redwoods are very important to the environment.
In 1997 Hill learned a group called Earth First was working to protect a particular group of trees. They decided to send someone up into a redwood tree, hoping this would stop the company from cutting the trees down. Julia Butterfly Hill volunteered.
Hill lived in the tree for over two years without ever coming down. Her home was a 6-by-8-foot tree house, 180 feet up. It is always cold and wet in a redwood tree. There were even very serious winter storms while Hill was in the tree. The wind and cold almost knocked Hill out of the tree. But she did not fall — she survived.
Finally, after years of arguing, the company decided to protect Luna, the tree Hill lived in. They signed an agreement to never cut down this huge redwood tree or the trees around it. When Hill put her feet on the earth again, she began to cry. But from that moment on Hill hasn’t stopped working to protect the environment.

【推荐1】Most environmental pollution on Earth comes from humans and their inventions, such as cars or plastic. Today, car emissions (排放物) are a major source of air pollution leading to climate change, and plastics fill our ocean, creating a significant health issue to marine (海洋的) animals.

And what about the electric light, thought to be one of the greatest human inventions of all time? Electric light can be a beautiful thing, guiding us home when the sun goes down, keeping us safe and making our homes bright. However, like carbon dioxide emissions and plastic, too much of a good thing has started to impact the environment. Light pollution, the inappropriate use of outdoor light, is affecting human health, wildlife behavior and our ability to observe stars.

Light pollution is a global issue. This became obvious when the World Atlas of Artificial Night Sky Brightness, a computer-generated map based on thousands of satellite photos, was published in 2016. Available online for viewing, the map shows how and where our globe is lit up at night. Vast areas of North America, Europe, the Middle East and Asia are glowing (发光) with light, while only the most remote regions on Earth (Greenland, Central African Republic and Niue) are in total darkness. Some of the most light-polluted countries in the world are Singapore, Qatar, and Kuwait.

Sky glow is the brightening of the night sky, mostly over cities, due to the electric lights of cars, streetlamps, offices, factories, outdoor advertising, and buildings, turning night into day for people who work and play long after sunset.

People living in cities with high levels of sky glow have a hard time seeing more than a handful of stars at night. Astronomers are particularly concerned with sky glow pollution as it reduces their ability to view stars.

More than 80 percent of the world’s population, and 99 percent of Americans and Europeans, live under sky glow.

【推荐3】Garbage has been negatively connected with germs(细菌), dirt and useless junk. However, a recent art exhibition proved that “useless” things can have practical significance.

Dear Pretty Rubbish, an art event organized by the World Wide Fund for Nature (WWFN) and digital media art company Blackbow, was held in Beijing. It looked at wasteful consumption (消耗) and asked questions about the relationship between our lifestyles and our garbage.

“We hope that everyone who visited the show can think about how ‘useless things’ are produced why they are throw away, and whether ‘useless things’ are really useless, ”said Cao Yujia, the design director of Blackbow.

The organizers said that all the raw materials for the exhibition were collected from community garbage cans.

Artists Zhou Yuxuan and Liu Yifan collected nylon cable ties (尼龙扎带), LED lights and beverage bottles from designers’ workshops to create a work where plastics, in the shape of cells “grow” in a corner. There, the lights blink (闪烁) regularly to imitate (模仿) “breathing”. When people walk near it, the work responds by forming light patterns, as if communicating with the visitor.

Speaking about the work, Zhou said. “It’s like some kind of communication between humans and plastics.” Plastic has a life longer than almost any creature, taking centuries to break down. Though people blame plastics for damage to the environment, they are a big part of our daily lives.

“So we want to ask the question: Although the damage continues, whether there is a way for humans to reconcile (调和) with plastics,” said Zhou.

Liu said that plastic waste can be used to make clothes “Re-use of plastics will be a future trend, ” he said. Cable ties are a useful and common material for fastening. Many people will buy a large bundle of them but only use a few pieces. The rest of cable ties could be re-used as a decoration in handicrafts.

“This exhibition calls for everyone to re-think their wasteful lifestyle full of single-use plastics and make changes, ”said Cao.
