1 . Earth Day falls on April 22 each year to inform people about environmental problems and inspire them to act. It first came into being in 1970, followed in 1972 by World Environment Day. It has been celebrated ever since, slowly but surely picking up steam. Interestingly, it remained a grassroots affair for 20 years before spreading out to 140 countries in 1990. Now, it is celebrated around the world. Humans still face many challenges, such as climate change and plastic pollution. But we can all make a difference.

When Claire was in the seventh grade, she learned about plans to expand and modernize her middle school. As a follower of Earth Day, she wanted to help. Claire asked the school board to add solar panels to the project because, she explained, clean energy would contribute to a truly modern school, and help her school pursue sustainable development.

The board liked the idea but said it could contribute just $25,000, one-fifth of the cost. So Clarie turned to the community, looking for a solution. Her friends and neighbors shared her enthusiasm. Soon Claire organized a group of kids and adults, who set to work raising the rest. They wrote grant (拨款) requests, put on a talent show and asked for donations, even going door-to-door for them at Halloween. And they appealed to charitable foundations too. One donated more than half the cost!

After two years of hard work, the group paid for the solar panels, which now supply one-fourth of the school’s electricity needs, saving the district thousands of dollars. “My favorite part about this project was that one person could start something small and then the project could grow and have a big impact on the community,” Claire said “There are always going to be barriers and hard parts. When there’s a challenge presented to you, use it as a learning moment and an opportunity to overcome it.”

You can be a hero for the environment, so find out what can be recycled where you live.

2 . “What if we treat the ocean as if our lives depend on it? Or, what if we don’t?” World-famous marine biologist Sylvia Earle poses her famous “what if” questions to inspire people to reflect on how they can help save the ocean. In 1998, Time magazine named Earle its first “Hero for the Planet.”

Earle’s move to Florida’s west coast at age 12 is what started a lifelong passion. She says, “That’s where I first fell in love with the ocean.” In 1953, using newly developed equipment, the young scientist became one of the first in her field to scuba dive (水肺潜水). Her first long-term exposure to the ocean depths came in 1970 when she led an all-female research team to study the ocean. They lived under the sea in a submersible (潜水器) for two weeks. When they returned to the surface, world-wide cheer and praise were waiting, especially for Dr. Earle.

Sylvia Earle’s career includes many firsts. In 1979 she became the first woman to walk the ocean floor 381 meters below the surface. In 1990, she became the first female chief scientist of the U.S. National Oceanic and Atmospheric Administration (NOAA).

Through the years, Earle has spent roughly 7,500 hours underwater. During that time, she has become increasingly alarmed by the significant changes she has observed.

The famous scientist fears that the ocean is dying. Climate change, overfishing, the dumping of trash and chemicals and oil spills are just some of the many causes. In order to tackle the problem, Earle formed Mission Blue in 2009. This organization promotes the legal protection and conservation of the world’s oceans. Her plan is to develop “Hope Spots,” protected areas large enough to reverse (逆转) damage and restore the ocean.

For those consuming Asian food, using chopsticks     1    (be) almost second nature. About 20 to 33 percent of people in the world use chopsticks     2     a daily basis. Not all of those are disposable (一次性的),     3     no doubt many are.

Felix Böck, a student at the University of British Columbia, was eager to find a way to recycle wood from construction projects, and he had a particular interest in bamboo. One day he found a drawer in his friend’s house     4    (fill) with disposable bamboo chopsticks, and an idea hit him.

He decided to give     5     second life to disposable chopsticks by making them into home     6    (decoration) or other accessories (配件). He told the idea to restaurant owners,     7    (convince) them to install recycling bins in their restaurants. He cleaned the chopsticks, pressed them into square pieces and coated them with glue. The square pieces were then     8    (creative) arranged into household and office products. Böck’s company, called Chop Value, has repurposed chopsticks into desktops, cutting boards and even table games.

Since 2016 when the company     9    (found), Chop Value has rescued billions of chopsticks from landfills. Instead of an economy of the typical take-make-dispose model, Chop Value seeks to create one     10     transforms waste into a usable resource.

4 . If you’re not at least a bit terrified by the climate and ecological breakdown unfolding before our eyes, you haven’t grasped the scale of the crisis. Eco-anxiety, defined as “a chronic(长期的)fear of environmental doom”, is on the rise. But redirecting this anxiety into anger and collective action might just pull humanity back from the brink.

We don’t yet know how deeply eco-anxiety affects people, but we can learn not to repeat the mistakes of long-gone societies lost to environmental collapse. Jared Diamond’s Collapse: How Societies Choose to Fail or Succeed uncovers the common driver that led to the fall of ancient civilizations such as the Central American Mayan, the remote Pacific Easter Island, and the Mycenae: People accidentally destroyed the environmental resources on which their societies depended.

Today, we are living in a new climate and ecological age. The new normal is one that humans have never before experienced on earth, and that has occurred within a single generation. We can’t claim ignorance. Numerous scientific reports show: unprecedented(空前的)wildfires in the Arctic, heatwaves annually breaking records, the Amazon shrinking and drying, and species extinction rates accelerating. Nature’s dangerous decline is unprecedented.

So, it’s not surprising that eco-anxiety is on the rise. Anxiety is often a private emotional state: We feel alone, stuck inside our own heads, and our emotions stop us from doing the things we want. But anger, directed appropriately, can fuel powerful collective action for change.

We are on a pathway to destroy the global conditions for human survival. Unlike previous civilizations, we have the science and technology to understand our danger and chart a new pathway. This is a moment for all of us to channel our eco-anxiety, fear and anger into energy for change.

5 . In the west of the Greek capital Athens, the fish market of Keratsini is busy early in the morning, with trucks waiting nearby to be loaded with fishes. But on his fishing boat, Arapakis sorts out something different—bottles, boots, plastic pipes and fishing nets, all dragged from the bed of the Aegean Sea.

“We are swimming in plastic,” said Arapakis, whose family has fished for five generations. “By 2050, there will be more plastic than fish in the sea,” he said, as recent reports noted.

That morning’s plastic catch weighed “about 100 kilograms,” said the founder of Enaleia, a nonprofit that encourages fishermen to collect marine (海洋的) waste caught in their nets. Since its establishment in 2018, it has worked with more than 1,200 fishermen in Greece to raise concern over the degradation of the marine environment.

Active in 42 ports throughout Greece, Enaleia provides fishermen with large bags for marine waste that they can put in garbage cans once back at port. For every kilogram of plastic they deliver, they receive a small amount of money, which is enough for a drink. Since October, fishing crews have dragged out 20 metric tons of plastic and old fishing equipment each month. Nearly 600 tons have been collected over the last five years. The collected plastic is transported to a recycling plant in the industrial area of Megara near Keratsini, to make new products such as socks, swimwear or furniture.

Arapakis said he went about the cleanup project after a trip to Greece’s Cyclades islands, where he saw fishermen throwing the waste gathered by their nets back into the sea.

Arapakis is convinced there has been a “mentality change” among Greece’s fishermen. “Previously we caught large quantities of plastic, but we only kept the fish. All waste was thrown into the sea,” said Mokharam, team leader on the Arapakis family’s boat. “The project brings practical benefits for fishing boats. In the past, the anchor was often caught by waste, especially nets, and the engine would go out. But now things have changed,” he added.

Trees are so important that some people have made it their goal to protect them. We can call these people ‌“tree hugger”. It describes people who support the protection of forests. Today, the term ‌“tree hugger” describes a person who is an environmentalist.     2     For example, someone who wants to save a rare butterfly species or cut greenhouse gases could also be described as a tree hugger.

However, calling someone a ‌“tree hugger” is not always seen as a praise.     3     ‌“Tree hugger” described someone who was overly concerned about protecting trees, animals and other parts of the natural world.

Some tree huggers do go to extremes to protect trees. Take, for example, an American woman named Julia Lorraine Hill. For 738 days from December 10, 1997 and December 18, 1999, Hill lived in Luna, a Redwood tree in northern California’s Humboldt County. Luna is huge, measuring nearly 61 meters tall and about 12 meters across, which has stood in Humboldt County for more than 1,000 years.     4     So, Hill did what any extreme tree hugger would—she moved in! As the website explains, Hill’s main goal was ‌“to bring international attention to the importance of protecting and restoring natural resources.” So, we can safely call Hill a tree hugger.     5    

10 . The African penguin lives on St. Croix island off the east coast of South Africa. A new study has found that they are leaving their natural environment to escape noisy ship refueling (补给燃料) activities.

The African penguins once mainly raised babies on this island. But the population has dropped sharply since South Africa started permitting ships in the area to refuel at sea six years ago, the study found.

Lorien Pichegru is acting director of the Coastal and Marine Research Institute at Nelson Mandela University, which led the study. She said the organization had found that noise levels in the area had doubled since the refueling activities began. Scientists say high noise levels affect the ability of penguins to find and catch other animals for food. Noise also makes it more difficult for them to communicate with each other and map travel paths. ‌“This year we are at 1,200 breeding pairs at St Croix from 8,500 pairs in 2016,” Pichegru said.

The study recently appeared in the publication Science of the Total Environment. The researchers said the study is the first to explore the effects of ocean traffic noise pollution on a seabird.

Nelson Mandela University’s study collected some data to estimate underwater noise from passing ships. Oil-covered penguins were found in 2019 in Algoa Bay after an oil spill from ship-to-ship refueling. Environmental groups have called for the activities to be banned in the bay.

Pichegru said penguins in the area were already struggling to survive because of a series of issues, including industrial fishing activities. She added that the refueling activities did not kill all the penguins. However, ‌“It was just the thing that made the whole ecology tip over and then the penguins couldn’t cope with that,” she said.
