2 . “Eco-mermaid” Merle Liivand wove a remarkable story with her attachment to the ocean. On March 7, she ________ her own world record by swimming a full marathon’s distance with a single fin (鳍) in Biscayne Bay, Florida. When Merle Liivand was a child, she had health problems, and began swimming to help her lungs get ________ . In one training session, she nearly ended up swallowing (吞下) some ________that was floating (漂浮) in the sea.

That ________ made her think of all the sea animals who faced ________ pollution every day. She decided to work to make people more aware of plastic pollution. Inspired by sea creatures, she began swimming with a special single swimming fin ________ both of her feet. This single fin allows her to swim by ________ both of her legs together. She believes swimming with it ________“a bigger message”.

Since 2022, she’s broken records, swimming vast distances — first in California, then in Florida, and this time swimming the________of a full marathon. Despite challenges like jellyfish (水母) stings, she ________ collecting trash along her route. Her dedication extends beyond records; it’s about community and global ________.

During her ________, a friend kayaked (划皮划艇) alongside, providing food and water and collecting the trash she ________. By the end of her marathon, the kayak held three bags full of trash. Liivand’s actions aim to ________a bigger goal: it’s not just about achievements, but about making a ________ impact on the world.

6 . As my husband and I drove down a country road, we passed a fire station with a sign that read. “Are you ready for the next storm?” Our area had just been in the path of Hurricane Irma, causing downed trees and power off.     1    

We have had our share of storms in the past — a snowstorm and other heavy snows that knocked down trees, sometimes up to a week at a time. Those days weren’t fun, but we learned so much from those early storms. It made later storms easier to bear.

    2     We bought a battery-operated radio to keep up with the news. We stocked up on batteries so that we’d have plenty for extended power failures. We make sure our grill is ready and its tank is full, and we purchase food that can be easily prepared and then cooked or heated on the grill.     3     We have book lights to read in the dark. We keep our car gas tanks full and have emergency cash on hand.

We’re ready for the next storm, but we wouldn’t have learned to do all those things if we hadn’t faced a storm in the past. The same is true spiritually. Those little storms in our lives are never fun, but they prepare us for the big trials coming to us.     4    

Are you ready for the next storm?     5    

7 . Eradajere Oleita thinks she may have a partial solution to two of her country’s problems: garbage and poverty. It’s called the Chip Bag Project. The 26-year-old student and environmentalist from Detroit is asking a favor of local snack lovers: Rather than throw your empty chip bags into the trash, donate them so she can turn them into sleeping bags for the homeless.

Chip waters drop off their empty bags from Doritos. Lays. and other favorites at two locations in Detroit:a print shop and a clothing store. where Oleita and her volunteer helpers collect them. After they clean the chip bags in soapy hot water, they slice them open, lay them flat, and iron them together. They use padding (衬垫) and liners (衬里) from old coats to line the insides.

It takes about four hours to sew a sleeping bag and each takes around 150 to 300 chip bags depending on whether they’re single-serve or family size. The result is a sleeping bag that is “waterproof lightweight and easy to carry around”. Oleita told the Detroit News.

Since its start in 2020, the Chip Bag Project has collected more than 800,000 chip bags and, as of last December, created 110 sleeping bags. Sure, it would be simpler to raise the money to buy new sleeping bags. But that’s only half the goal for Oleita — whose family moved to the United States from Nigeria a decade ago with the hope of attaining a better life —and her fellow volunteers. “We are devoted to making an impact not only socially, but environmentally,”she says.

And, of course, there’s the symbolism of rescuing bags that would otherwise land in the trash and using them to help the homeless. It’s a powerful reminder that environmental problem and poverty often go hand in hand. As Oleita told hourdetroit.com, “I think it’s time to show connections between all of these issues.”

With best wishes,

9 . In many ways, life has become far more comfortable and convenient in the past few decades.     1     Here, we look at three of the most serious environmental problems we are currently facing.

Air Pollution

The main cause of air pollution is the burning of fossil fuels by vehicles and power plants. Other human activities, such as construction and the burning of waste, also contribute to air pollution. The effects on our health can be very serious.

You can easily contribute to reducing air pollution by only using a car to make journeys when it’s absolutely necessary.     2    

Global Warming

Global warming is the increase in the temperature of the Earth’s near-surface air and oceans. It’s caused by the build-up of carbon dioxide and other pollutants in the atmosphere. These trap the Sun’s heat and warm up the planet.

Global warming has already caused a wide range of problems.     3     Countries around the world have faced extreme weather conditions, such as hurricanes, floods and heat waves.

Overflowing Landfills

Landfills are used for waste disposal (处理) in many countries around the world. However, these landfills are now nearing their limit. When this happens, the chances of dangerous chemicals in the waste entering our water supply increase.

The amount of waste in landfills in China has risen sharply over the last ten years.     4     Some cities, such as Beijing, Shenzhen and Shanghai, among others, are leading the way and have promised to send “zero waste to landfill!”.

    5     They believe that, although recycling waste is effective, the most effective way of solving the problem of overflowing landfills is to encourage people to take responsibility for reducing the waste they produce themselves.

10 . Topher White spends so much time walking in the forest and thinking about how quickly we’re losing it. The engineer is determined to stop global deforestation. Founder of the San Francisco-based non-profit Rainforest Connection, White has developed a small but clever strategy: using old cell phones to listen for the sound of destruction.

Forests are disappearing worldwide, and fast：an area about half the size of England is lost each year. The Amazon has lost close to one-fifth of its rainforest cover in the last four decades. Forest loss not only harms wildlife, including many species that live nowhere else, but it’s also a big contributor to the greenhouse gas emission(排放)that cause climate change.

”I didn’t know any of this when I started,“ says White, who began his journey in 2011, when he traveled to Indonesian Borneo to help decreasing gibbons(长臂猿).

Between 50 and 90 percent of the logging that happens in the world’s rainforests is illegal, according to White, yet detecting chainsaws(电锯)and other sounds related to that activity can be tough, because the air is already filled with the loud unpleasant mixture of sounds from nature. So he has developed a system in which he installs a cell phone that stays charged by solar cells, attaches an extra microphone, and listens. From there, the device can detect the sounds of chainsaws nearly a mile away.

Because it’s unfeasible to have people listening to the devices all the time, he added some “old-school data analysis”, so that the cell phone’s computers can distinguish a chainsaw’s sound from others in the forest. This way, his device can automatically detect logging activity and send a text alert to authorities who can determine if it’s illegal and then stop it.

White notes that he’s not alone in the fight: Many people and organizations are working tirelessly to stop forests from disappearing. For instance, local groups are particularly active in forest conservation efforts, White says.

So far, his monitoring devices have been used in Cameroon, Ecuador, Peru, and Brazil and will soon be used in Bolivia. It’s not just about listening for logging. The same technology that can pick out the buzz of a chainsaw can pick out the sounds of specific birds, which is why Whtie sees the forest recordings as a potential science tool. He’s urging biologists and ecologists to use his monitoring system anywhere, whether it’s a remote forest or a park in London. “The more we learn about these places,” he says, “the easier it’ll be to protect them.”
