2 . Back in 2007, Uruguay had a serious problem with no obvious answer: The economy was growing very fast, but there wasn’t enough energy to power the rapid _________.

Then Ramón Méndez Galain, a physicist, started _________ different potential paths for Uruguay’s energy future. Finally, he wrote a plan that Uruguay could almost entirely _________ renewable energy. There would be less _________ and it would be the most economical choice Uruguay could make in the long run.

Méndez Galain’s plan was built around two simple _________ about his country. First, while there wasn’t a domestic (国内的) supply of coal or oil, there was a great deal of _________. Second, that wind blew over a country that was known for _________ grassland. His plan for Uruguay’s energy future was to _________ the empty grassland into hundreds of wind farms.

To solve the problem of how to pay for all those wind farms, Méndez Galain came up with a variation on a(n) _________ used by some electric plants in neighboring Brazil, in which state owned power plants handled energy generation, while __________ companies were in charge of power distribution and customer service. Méndez Galain’s plan changed the relationship to the __________, so that private companies would be in charge of setting up and __________ the wind farms, while the state-owned power companies would distribute that energy to its customers.

The strategy worked __________ well. Just within a few years, Méndez Galain had __________ what he had set out to do: 98% of Uruguay’s __________ comes from renewable sources.

3 . In the rich countries of the West, the electric vehicle revolution is well underway. Climate-conscious consumers drive Teslas or Polestars for reasons of morality and fashion. Poorer countries are also experiencing a wave of electrified trend. In Bangladesh, electric three-wheeler taxis, known as tuk-tuks, are rapidly replacing gas-powered ones on the streets. Such electric vehicles are climate friendly, cost effective, and help reduce air pollution.

Yet a glance under the hood (引擎盖) of these vehicles reveals a poisonous secret: each tuk-tuk runs on five massive lead-acid batteries, containing almost 300 pounds of lead in total. Every year and a half or so, when those batteries need to be replaced and recycled, about 60 pounds of lead leak into the environment. Battery recycling, often at small-scale unregulated factories, is a highly profitable but deadly business.

Lead is dangerous, and any exposure to it is harmful to human health. Lead that has entered the environment hurts people on an extraordinary scale. The numerous ways lead enters air, water, soil, and homes across the developing world — and the enormous damage it does to human health, wealth, and welfare — causes one of the biggest environmental crises in the world yet receives little attention.

The World Bank estimates that lead kills 5. 5 million people per year, which would make it a bigger global killer than AIDS, malaria, diabetes, and road traffic deaths combined. On top of the shocking deaths, the social burden of lead poisoning is extraordinary, as is its contribution to global inequality — our research on the cognitive effects of lead poisoning suggests that it may explain about one-fifth of the educational achievement gap between rich and poor countries.

But unlike many challenges faced by developing countries, lead poisoning is a problem that is fixable with some attention and a relatively modest financial investment. Better monitoring, research, and rules can help protect children all over the world from the dreadful effects of lead poisoning and reduce the massive global costs it brings.

6 . When most kids go to the beach, they’re too focused on making sandcastles and splashing around to notice litter, but several years ago, for 7-year-old Cash Daniels, noticing a plastic straw sparked a lifelong passion for saving the planet.

Cash, who is now known as the “conservation kid”, has always loved nature. He grew up fishing along the Chattanooga River, after all! But once he learned that 80 percent of all trash from land and rivers ends up in the ocean, he couldn’t sit back.

He started with cleanups along the river, something that quickly went from a family affair to a community effort with volunteers and neighbors. In 2019, Cash, together with a Canadian conservationist, Ella Galaski-Rossen, started a nonprofit called the Cleanup Kids. Despite living in different countries, they managed to create educational videos on their YouTube channel. “We hope to be a really big nonprofit that eliminates plastic in the U. S. and Canada,” Cash said. “We want to inform kids and adults in the landlocked states on how their actions are connected to the water and the ocean,” Cash said.

Cash was selected as one of America’s top 10 youth volunteers of 2021 by the Prudential Spirit of Community Awards. He also earned the title of National Honoree, where he received a$5,000 grant to go to a nonprofit of his choice, and he became the first person to win the Youth Conservationist Award two years in a row from the Tennessee Wildlife Federation.

“I want to travel the world, teach others, and help them feel connected to the ocean. Because if you are connected to the ocean-if you love it and what lives in it—you’ll want to protect it,” he said. “This is my fun, and it becomes more fun with every new discovery.”

7 . People have different ways of dealing with waste paper, specifically used newspapers. Some put them in the recycling area, while others keep them as wrappers (包装纸). While these are both good measures, a Japanese publishing company had a better idea for their end use.

The Mainichi Newspapers Co., Ltd. invented the “Green Newspaper”, which allows people to grow plants with it. This unique newspaper was published on Greenery Day, which is focused on environmental news and made of green paper with seeds placed into it. What makes it even more special is the ink (油墨) used to print words and photos, which is made from plants. The publisher advises readers to tear the used newspaper into small pieces and plant them in a container with soil. They should water them, like they would do for any plant. Within a few weeks, the seeds will grow into plants.

This brilliant concept was invented by Dentsu Inc., one of Japan’s most famous advertising agencies, which works with the publishing company on the initiative (倡议). The publisher’s belief is environmental sustainability (持续性). As its mission statement says, “The Mainichi doesn’t take action only through information, but also by solving global issues.” With joint efforts, this initiative has reached the corners of Japan and sold around millions of copies daily. Other such initiatives producing plantable paper are also seen in India and the US.

About 95 million trees are lost for producing newspapers every year. The Internet, the number of whose users stands for 62.5 percent of the population worldwide, has influenced how people read news and the print readership has dropped greatly. However, the reinvention and reimagination of this newspaper will bring about a change in the publishing industry as well as having an environmental influence.

8 . The first rule of popular science is to reveal the wonder and mystery of the world. For that reason, Sentient (Picador), written by photographer and wildlife film-maker Jackie Higgins, is my pick of the year. According to my interviews with many readers, I select other four newly-published books in 2022.

This book describes how our ancestors hunted and consumed ancient animals such as mammoths, bison, giant camels and many more now-extinct species. The diet of the Clovis peoples of North America was a menu described as “a record of a lost world”. This book explains how our dinners robbed the world of so many large animals. It gives inspiration for how modern humans can be at peace with nature.

In 1999, Mann published a graph showing the rapid post-industrial rise in global temperatures. Two decades later, his book The New Climate War remains convinced that we can prevent climate change. This book sets out a common-sense approach to carbon pricing and a revision of the Green New Deal. Of course, there are still many people who deny that climate change is even happening.

Physicist Kate Greene imagines that she spends four months in a geodesic dome in Hawaii, with five other people, to mimic living in a colony on another planet. The story describes the future of our Earth. Kate makes readers cherish the natural environment. “No sunshine on our skin, and no fresh air in our lungs,” Greene turns the frustrations into a moving story.

The birds were once common across the peninsula. But as development over the last 100 years reduced the habitats on which the bird depends, the species became endangered. Mark Walters travels the state to report on the natural history and the current situation of Florida’s flag ship birds. This book can raise people’s awareness of protecting the birds’ habitats.

10 . With greater climate disasters lying ahead, it is natural for us to make every effort to stop a series of floods, unusual snowstorms, and alarming reports from scientists. For many of us, part of that means running out to buy reusable drinking tubes, organic cleaners, and packaging-free products.

However, before you are joyful of your “green” purchases, take a second to consider a principle that should be obvious: simply consuming less is better for the planet. After all, every new item a factory pumps out requires some resources to produce. But in the confusing stream of environmental news, this simple truth can get lost. Take plastic bag bans for instance. If your city is getting rid of single-use shopping bags, it can be tempting to pay for that fashionable organic cotton bag hanging in the check-outline of supermarkets. However, experts who have analyzed the data on environmental impact insist that growing cotton is actually no better for the Earth than producing the conventional plastic bag. Any bag you already own is your best bet for carrying your groceries if you care about sustainability.

It is not just the Earth that will be happier if you buy less. You will feel more contented too. There is a common view that green buying patterns mean people are going green. However, it doesn’t seem to be that way. Reduced consumption has positive effects on increased well-being, but you don’t see that with “green” consumption.

Many studies have shown that materialism in general makes us unhappy and lonely. It is perfectly possible to be a materialist and an environmentalist at the same time. Lusting (欲望) for every new “green” product on the market might make you feel good about yourself but it presents the same emotional traps as lusting for whatever the Joneses next door are buying. If you relieve yourself of that burden of ownership, most people report feeling a lot better and freer.
