1 . Visitors post photos and videos of themselves getting close to flamingos at several resorts (旅游胜地) in Punta Cana, Dominican Republic on social media. The pink, leggy birds wander the grounds, walking through artificial ponds and eating food dropped by tourists.
“But behind the fantastic social media posts, things are less rosy for the flamingos,” says Fernandez, a Dominican conservationist and photographer.
Some of these flamings have their secondary feathers cut, which prohibits flight. Others have a bone removed from their wings. This grounds the bird for life, which can be up to 60 years.
Fernandez has also witnessed flamingos being given much pet food, which eventually fades the pink color that comes from eating their native diet of shrimp and other small crustaceans. The birds change behaviorally as well, becoming used to people and asking them for food, as Fernandez has seen.
On the other side of the country, Monte Cristi National Park is the natural habitat for Caribbean flamings; it’s also a popular trapping site. And it is here that Paulino works to remove the traps, which are made of wooden sticks attached to fishing wires.
Paulino’s group first noticed the traps in 2009 and has been reporting them to the authorities ever since, but the practice hasn’t stopped. Once, Paulino says, she spotted a trapper carrying nine flamingos in a bag. On a trip early in 2023, the group took 706 traps from three locations.
This method of trapping harms, or even kills the birds, which Paulino has seen firsthand in the field. Flamingos are walking around and all of a sudden their leg falls in the wires and when they pull, they’re caught. They are trapped by the knee or the ankle, and struggle to break free, which exhausts them.

2 . 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.”

3 . 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.

4 . Electric cars have been gaining popularity in recent years, and for good reason. Not only are they cost-effective in the long run, but they also offer many benefits for the environment. Here are three reasons why electric cars are great for the planet.
One of the biggest advantages of electric cars is that they produce zero emissions (排放). Unlike gasoline cars that emit harmful pollutants into the air, electric cars are powered by electricity that is generated from renewable sources such as wind or solar power. This means that when you drive an electric car, you’re not only saving money on gas, but you’re also helping to improve air quality.
Electric cars also save more energy than gasoline cars. When you drive a gasoline car, only about 20% of the energy made by the fuel is actually used to move the car forward. The rest of the energy is lost to heat and other things. Electric cars, on the other hand, convert (转化) almost 100% of the energy stored in the battery into motion. This means that electric cars can travel further on the same amount of energy, which is great news for the environment.
Another benefit of electric cars is that they reduce our dependence on fossil fuels. Gasoline cars are powered by gasoline, which is a non-renewable resource that is taken from the earth. As we continue to use gasoline, we’re using the earth’s natural resources and contributing to climate change. By driving electric cars, we can reduce our need for gasoline and move towards renewable sources of energy.
In conclusion, electric cars offer many benefits for the environment, including zero emissions, energy efficiency, and reduced need on fossil fuels. As more people make the switch to electric cars, we can help to create a cleaner and more sustainable future for ourselves and for future generations.

5 . When nine-year-olds Ella Grace Rossen and Cash Daniels met in July 2019, they immediately connected. When their moms introduced them, they had no idea that the kids were about to become an environmental-activism powerhouse pair.
“We knew we could make a difference together, ” says Cash from his home in Ella agrees. “It was pretty much instant best friends.”
Within a short time, their meeting transformed into action, birthing the Cleanup Kids — a youth-led non-profit determined to make waves in environmental conservation.
Ella’s passion for the environment started with an early love of sharks and many first-hand encounters of cleaning up trash along the shores of Vero Beach. For Cash, the spark was ignited (点燃) at just seven years old, when a single plastic straw on the beach caught his eye, symbolizing a much larger issue. That’s when he became aware of the crisis facing thousands of turtles, seabirds and other wildlife, which risk death from consuming discarded plastic.
“My hope for the Cleanup Kids is that it’s not hundreds of kids, it’s thousands of kids who have joined us, and for that to have a chain effect,” says Ella. Member responsibilities include conducting at least one cleanup per month, documenting and photographing the collected trash, and sorting and recycling items. It’s a lot of work, and it hasn’t gone unrecognized. In 2022, out of more than 700 applicants from across North America, Cash and Ella were chosen as one of 25 projects to receive the Gloria Barron Prize for Young Heroes.
How do you even begin to make that impact? Cash’s best advice is to start small. “I started with just a couple cleanups with my family. Don’t overdo it,” he says. “And just remember that kids may be only a small part of the population, but we’re 100 percent of the future.”

6 . A carbon footprint is only one component of the broader ecological footprint. An ecological footprint compares the population’s consumption of resources and land with the planet’s ability to regenerate. The Earth’s ecological footprint is currently 23 percent over capacity. It takes about one year and two months to regenerate what we consume in a year.
Carbon footprints help people keep track of changes. Because footprints quantify an amount of carbon that increases or decreases based on energy use, they let people know that a new hybrid car or home insulation (隔离) helps. Transportation accounts for 33 percent of CO2 emissions in the United States, so many people try to lower their mileage (里程). Some walk or bike whenever possible; others take public transport. Home energyuse accounts for 21 percent of U. S. CO2 emissions, so it helps to have an efficient home. Setting the thermostat (恒温器) at a moderate temperature and installing double-paned windows lowers energy costs.
Of course, individual efforts can go only so far. Cutting CO2 and other greenhouse gases down to safer levels requires significant government regulation. Lessening carbon footprints does let people see where they are and how they can change. Those who want to accept personal responsibility for their emissions can track their own reductions and change their habits.
Because carbon calculators ask for only rough estimates, it’s easy for investigators to approximate the footprints of celebrities and politicians. Analysts hope to uncover high-profile figures, especially those who promote environmentalism. Although performer Madonna and other celebrities have been accused of flying frequently, former vice president Al Gore has drawn the harshest accusations. The Gores’ spokesperson did not deny that but emphasized that the couple subscribes to green power.

7 . Ten years ago, environmental journalist Ben Goldfarb was on a reporting trip about wildlife conservation. When he was shown around some new animal crossing structures near, Missoula, these new bridges and tunnels intrigued him. He was attracted by these beautiful human-built structures and inspired to write a book. Crossings: How Road Ecology Is Shaping the Future of Our Planet has now been published.
Through expert interviews, in-depth research and convincing analysis, Goldfarh brings to life the deadly consequences our 40 million miles of roadways have had and are having on the natural world and the creatures that inhabit it. A million animals are killed by cars each day in the US alone. Road salt pollutes lakes and rivers. And there's the barrier effect-the steady stream of traffic that prevents animals from migrating (迁徙) all together and finding habitats. Goldfarb writes that noise pollution is the most worrisome among all the road's ecological disasters. Both the engine noise and the tire noise greatly impact ecological environment.
Figures on deaths and disruptions (扰乱) are disheartening, but Goldfarb vividly describes how scientists are actively working on meaningful improvements to help animals and roads better coexist, such as wildlife crossings, from passages in Canada's Banff National Park to the famous Liberty Canyon Overpass in Los, Angeles. Another example is that in India, they built a new highway through a tiger reserve so that animals can come and go underneath the lifted freeway. Of course, that made the project more expensive, but it's ecologically the right thing to do.
Crossings is a truly important and landmark book on a subject whose full impacts continue to be disregarded or underestimated in considering conservation efforts. The book is a sympathetic, heart-warming guide to exploring the issues of wildlife survival and our own.

8 . The California sea otter (海獭), once hunted to the edge of extinction, has staged a thrilling comeback in the last century. Now, scientists have discovered that the otters’ success story has led to something just as remarkable: the restoration of their declining coastal marsh (沼泽) habitat.
Elkhorn Slough, a coastal marsh within Monterey Bay, had been experiencing severe damage. The root cause was a growing population of shore crabs, which fed heavily on the marsh plants, weakening the structural integrity of the habitat. Coastal marshes like these are not only natural defenses against storm waves but also serve as important carbon storage areas and water-cleaning systems.
The conservation-driven comeback of the sea otter has been crucial. California’s coastlines were once alive with sea otters. Sadly, they were nearly wiped out at the hands of fur traders. In the 1980s, conservation efforts aided these otters in re-occupying large areas of their former range. Now, Elkhorn Slough has the highest concentration of sea otters in California, with a population of about 100. By naturally feasting on crabs, the otters have helped a significant regrowth of plant life. Brent Hughes, a scientist working alongside Angelini, led a three-year study. Their findings were clear: in areas with sea otters, crab numbers fell markedly. This led to a resurgence in plant growth, which in turn stabilized the soil and lowered the rate of soil washing away.
As the sea otter population continues to restore, their positive impact on coastal ecosystems is likely to increase. It not only showcases the sea otter as a central species—a species that has a significant effect on its natural environment—but also highlights the essential nature of top predators (捕食者) in preserving ecological harmony. “My honest reaction was—this could become a classic in the literature,” says scientist Lekelia Jenkins. She reveals marsh restoration also helps people by reducing flooding. “Suddenly, sea otters go from just cute things we like to something that can protect our livelihoods and our properties.”
What change did the disappearance of sea otters bring about?| A．Fewer predatory crabs. |
| B．More coastal plant life. |
| C．Better water-cleaning effect. |
| D．Worse coastal ecological balance. |
