The Araguaia River is one of the biggest rivers in Brazil. It is home to thousands of animals. River dolphins swim and play in the water, and there are many different colored fish.
In one town, a 13-year-old boy named Rhenan walks along the river every day. But looking at the river makes him worry because there is rubbish everywhere. He sees plastic bottles, old clothing, and empty food packages. The water looks dark and ugly.
One day Rhenan asked about the dirty river at school. “You wouldn’t want rubbish in your house,” said his teacher. “Think about the poor animals!” For days, Rhenan couldn’t stop thinking about the river. It doesn’t seem right to him that this big and powerful river is filled with rubbish. “It’s hurting the animals in my area,” he thought. “And it’s also hurting the families who live here.” Then Rhenan had an idea.
The next morning, Rhenan talked to his mother about his plan for the river. He wanted to go around his town and ask for everyone’s help. Maybe if they all worked together, they could clean up the river!
Rhenan’s mother loved his idea. “I believe the most important thing for you, Rhenan, is learning how to change things that you care about. That will stay with you forever.” She said. She told him she would help him along the way.
The next day, Rhenan went to the police department and next to the office of the Mayor (市长). He visited offices, businesses, and other schools. Soon he had a very big group of people who like his idea! They all decided to meet at the river the following week. On the day of the river clean-up, Rhenan was excited—but he was also nervous. What if no one showed up? But when he and his mother arrived, there were almost a hundred people there, including many of Rhenan’s friends.

2 . Off Australia’s northern coast, the remains of ancient coral reefs (珊瑚礁) form the bedrock of wooded islands, which are home to diverse animals and plants, including mangrove (红树林) forests that blanket their coasts and serve as vital habitats and carbon storers. A recent survey shows that expanding seas might have led to a massive mangrove increase, researchers report November 1 in Proceedings of the Royal Society B.
Mangroves absorb carbon dioxide and store it as “blue carbon”, a term for carbon that is hidden away in ocean environments. “There’s a lot of interest in using mangrove blue carbon to lessen climate change,” says Kerrylee Rogers, an environmental scientist at the University of Wollongong in Australia. But there remain a lot of questions around their capacity to adapt to sea level rise.
In 2021,a team led by Wollongong environmental scientist Sarah Hamylton visited the Howick Islands to do a related research. They walked through the seawater to assess the plant diversity and measure individual trees. Using the measured widths and heights of several mangroves, the team calculated tree widths for the rest of the forest from the data to estimate the total mangrove quantity. The islands host nearly 54,000 metric tons of mangroves, the team estimates, which is roughly 10,000 more metric tons than there was in 1973.
The Howick Islands are uniquely suited to supporting mangroves as the ocean rises. At the end of the Last Glacial Maximum, around 12,000 years ago, water levels rose around northern Australia, and coral reefs grew upward to fill the space that had opened for them.
When sea levels fell thousands of years later, the exposed reefs became sediment (沉积物). With sea levels now rising again, the mixture of saltwater and sediment makes a perfect home for the salt-tolerant mangroves.
Rogers and Hamylton are now working on a bigger effort to study mangoves around Australia. “If we’re going to invest in mangroves to provide us blue carbon and to protect shorelines, we need to understand how dynamic they are,” Rogers says.

3 . The ocean is home to more than 200,000 known species and as many as 2 million that we have yet to discover. And, it is also home to 24.4 trillion pieces of microplastics. In 2022, researchers spotlighted how bad marine microplastic pollution, is getting: The total amount of microplastics on the bottom of oceans has greatly increased. in the past two decades.
Microplastic particles don’t just end up at the bottom of the ocean. Animals are eating them — at least 1,500 species have been reported to ingest plastic. And a lot of it. For example, whales in New Zealand’s Hauraki Gulf consume roughly three million microplastics daily, according to research published in Science of the Total Environment, which analyzed whale waste to see how much microplastics were present.
“Other research has shown that if plastics are small enough, they can cross the gut(肠道) wall and get into internal organs though the long-term effects are still unclear. Plastics can also release chemicals that are harmful to digestive system,” says Kahane-Rapport. “This is concerning, and while we do not yet understand the long-term health-effects, it is likely not a good sign for whales and their prey(猎物) to eat a man-made material like plastic.”
This is obviously bad for whales, but it also has effects on humans and the ocean at large. We are also part of these food chains and are consuming microplastics regularly. They are in our bottled water, in our table salt — they are even in our house dust and in the air we breathe. And we still don’t know what the health effects are. Meanwhile, the impact on whales — and what it indicates — is troubling on many fronts. “Whales are ecosystem engineers,” says Kahane-Rapport. “They can spread the nutrients that they consumed and serve as ecosystem guards — when whales are not healthy, other parts of the system will suffer.”
Kahane-Rapport says more research is needed. “The next research step will be to determine how much plastic the whales excrete(排出) and how much is left in their bodies. Following that, we would be able to determine the direct health effects on their tissues.”

4 . The Amazon
The Amazon River, the basin of which covers 2.3 million square miles, is incredibly biodiverse with over 30,000 species of plants and 1,800 species of birds. It plays an important role in adjusting the climate in North and South America. The River and its forests are threatened by human activity, primary pollution and rapid resource depletion (损耗). The Office of the American States Department of Sustainable Development is working to manage the threats.
The Mississippi
The Mississippi rises in western Minnesota and flows south for 2,530 miles into the Gulf of Mexico. Millions of people in over 50 cities use water from the Mississippi, and the river is also used for shipping and agriculture. Hundreds of animal species, including 60% of North America’s birds, call the area around the Mississippi River home, but river pollution and shoreline habitat destruction threaten to displace them. Fortunately, many projects and organizations are devoted to its conservation.
The Danube
The Danube River begins in western Germany, flowing over 1,775 miles into the Black Sea. It spans 19 countries. The Danube features a richly diverse ecosystem, hosting 55 different species of fish. Cities across Europe use the Danube for power generation and agriculture, and there are more than 700 dams in total. Unfortunately, this river is overfished and heavily polluted. The International Commission for the Protection of the Danube River was established in 1998 to manage its conservation.
The Mekong
The Mekong River is a necessary part of Southeast Asia’s landscape, culture, and economy. Also called the Lancang River, it starts in China, stretching over 2,850 miles through Burma, Laos, Thailand, Cambodia, and Vietnam. Its basin provides more than 65 million people with food, drinking water, power, and transportation. Dams and power plants are harming Mekong’s ecosystems. Organizations such as Conservation International are working to protect the river by advocating for its sustainable development.

5 . Like many of the Indigenous (土著的) communities across the Australian continent, the remote communities in north-west New South Wales are struggling. Many of the 300 or so residents rely on welfare. Higher electricity bills—up to $3,000 a quarter for some households—further worsen the poverty. They’re always at the end of the power line, so the service that is there is quite extraordinary in terms of cost. It’s a real problem that needs to be fixed.
To that end, Anderson and other Indigenous leaders have formed the First Nations Renewable Energy Alliance (FREA) to push for renewable energy in Indigenous communities. They partner with private enterprise to support Indigenous communities looking to switch to renewable energy.
“We can build a power station where the community exists,” Anderson says, “so people are able to successfully live in the environment the way they want to live and have access to power which enables them to better determine their economic future.”
Only a handful of Indigenous communities have set up renewable energy projects in Australia. The Indigenous-owned and -operated company AllGrid Energy, for instance, has installed solar panels and battery storage systems to replace diesel (柴油) generators in the communities of Ngurrara and Kurnturlpara in the Northern Territory’s Barkly Tableland. Within two months of the system being installed in May 2016, people were moving back to their homelands, the communities growing from just two permanent residents to about 40.
But FREA will go one step further, working with community leaders and acting as a conduit (纽带) between the communities and the businesses they are dealing with. This is essential, says Anderson, to avoid predatory (吞并) practices they have seen in the past, with companies “playing on the psychology of poverty” to gain advantage. The FREA has drafted terms of agreements that will guide how companies engage with Indigenous communities for renewable energy projects.
One of the next steps for FREA will be to identify a community that can act as a test case for a renewables project. “Our experience is that if we can make it work for one community, it will work in every other community,” Anderson says.
1. What is FREA expected to do for the remote Indigenous communities?| A．Increase power supply to them. | B．Help them return to their homelands. |
| C．Shake them off poverty. | D．Reduce their higher power costs. |
| A．Renewables projects are inaccessible. |
| B．Renewables projects are quite workable. |
| C．Renewables projects can increase locals’ income. |
| D．Renewables projects can coexist with diesel power plants. |
| A．Its strategies to win over the businesses. | B．Its cooperation with community leaders. |
| C．Its potential conflict with energy companies. | D．Its innovation in directing renewables projects. |
| A．Consult the experts. | B．Select a piloting community. |
| C．Collect sufficient construction fund. | D．Make renewables projects available to all. |
6 . Any schoolchild knows that a whale breathes through its blowhole. Fewer know that a blowhole is a nostril (鼻孔) slightly changed by evolution into a form more useful for a mammal that spends its life at sea. And only a dedicated expert would know that while toothed whales, such as sperm whales, have one hole, baleen (鲸须) whales, such as humpback and Rice whales, have two.
Even among the baleen whales, the placing of those nostrils differs. In some species they are close together. In others, they are much further apart. In a paper published in Biology Letters Conor Ryan, a marine biologist at the Scottish Association for Marine Science, suggests why that might be. Having two nostrils, he argues, helps whales smell in stereo (立体空间).
Many types of baleen whales eat tiny animals known as zooplankton (浮游动物), which they catch by filtering (过滤) them from seawater using the sheets of fibrous baleen that have replaced teeth in their mouths. But to eat something you first have to find it. Toothed whales do not hunt by scent. In fact, the olfactory bulb—the part of the brain that processes smell—is absent in such creatures. But baleen whales still have olfactory bulbs, which suggests smell remains important. And scent can indeed give zooplankton away. Zooplankton like to eat other tiny creatures called phytoplankton (浮游植物). When these are under attack, they release a special gas called dimethyl sulphide, which in turn attracts baleen whales.
Most animals have stereoscopic senses. Having two eyes, for instance, allows an animal to compare the images from each in order to perceive depth. Having two ears lets them locate the direction from which a sound is coming. Dr Ryan theorized that paired blowholes might bring baleen whales the same sorts of benefits.
The farther apart the sensory organs are, the more information can be extracted by the animal that bears them. The researchers used drones to photograph the nostrils of 143 whales belonging to 14 different species. Sure enough, baleen whales that often eat zooplankton, such as the North Atlantic right whale, have nostrils that are farther apart than do those, such as humpback whales, that eat zooplankton occasionally. Besides allowing them to breathe, it seems that some whales use their blowholes to determine in which direction dinner lies.

7 . Watford and her family have lived in Curtis Bay, Baltimore for generations. Her community has faced environmental injustice. Heavy industries continued to move in her community. As a result, her neighbors have had to live with serious respiratory (呼吸的) problems.
When she knew a plan to build the nation’s largest trash-burning incinerator (焚化炉) less than a mile away from her high school, she realized she had to take action. The incinerator was being sold wrongly as clean, renewable energy equipment but actually it would be a source of brain-damaging chemicals and would release 200 million tons of greenhouse gases per year, both worse than coal burning. Watford felt she had a responsibility to warn her community to work together to shut this plant down.
She co-founded Free Your Voice (FYV), a 10-person student organization devoted to community rights and social justice. Together, they decided to start a campaign to take down Energy Answers, the incinerator’s developer. They went door-to-door talking to neighbors and organizing protests.
When it was discovered that Baltimore City Public Schools (BCPS) was going to be a customer of Energy Answers, the organization fought with the board and presented their case, urging BCPS to withdraw from the project. BCPS was convinced to cancel their contract, which in turn inspired 22 other customers to do the same. Without any financial gain, Energy Answers had no market to move forward with its plan.
Watford continues to work with Curtis Bay residents toward fair development. They have a vision for the future which includes building a zero-waste movement, a solar farm, and green jobs. She wants the entire human family to join the fight for environmental justice because survival as a species depends on our ability to take action.

I was eight years old when my mother was told that she would never walk again without calipers (双脚规形夹) , and she wished to visit doctors in London.
The day before we boarded the ship, father committed (托付) his pet dog, Spider to his friend Sandy while we were overseas. We didn’t know how long my mother’s treatment would take or how long we would be away.
Six weeks later, an air-letter arrived from Sandy, saying that Spider had run away just two weeks after we had sailed and that despite many efforts, the dog was never found. I will always remember my father’s eyes watery as he read this news. Though my mother and I tried to comfort him, we knew in our hearts how useless that was.
We sailed back to Australia two years later. My father immediately began his own search for Spider. After many false calls, we had to accept the fact that the dog was gone.
One cold winter’s Saturday morning eight months after our return, my father had a call from Gin Gin, an old lady 375 kilometers away. On the phone she said she had been putting food out “for a very yellow old dog” in the night for weeks and “it was just glimpses of the similar dog in the shadows” in her disused tennis court.
That was enough for my father to drive five and a half hours to see this yellow dog. Sadly, Gin Gin told us the yellow dog hadn’t been around for a few days. My father had a strange look in his eyes.

10 . 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.
