2 . At Marine Mammal Laboratory, laboratory director Herman put a dolphin through its paces. Using hand signals, Herman asked, “Is the ball in the pool?” The dolphin correctly pressed a lever for “YES”. Herman asked it to push the ball to a basket. It did. Then he signaled his pupil to do it again, but he removed the basket. Herman expected the dolphin to be confused. Instead, it carried the ball to the NO lever and stopped there. Herman was astonished. “This is a totally untrained, invented response,” he said, “We never dreamed the animal would ‘think’ the problem through like that.”
To get a closer look at these amazing creatures, Herman and his team spent a week on board the Jennifer Marie. Whenever they heard the cry “Dolphins!” they slipped into the water. The dolphins approached, curious about them, observing them with dark, liquid eyes. Dolphins love to imitate. If they swam on their backs, Dolphins did too. If they dived, Dolphins followed. This talent can be carried to extraordinary lengths. In one instance, a trainer blew a puff of cigarette smoke against the window of an observation tank. A young dolphin rushed to its mother, nursed briefly, and spat out a cloud of milk against the glass.
Herman said “We’re still in the early stages of learning about the intelligence of these animals and our ability to communicate with them.” Scientists are amazed at dolphins’ intelligence, but fear for the future of these trusting ocean creatures.
Dolphins’ trouble could be sharks, killer whales or, worse yet, a fishing vessel. Indeed, in the past three decades, commercial fishing, especially the biggest threat—the drift net fishing, has greatly decreased the world’s dolphin population. Every night in the North Pacific, hundreds of Asian fishing vessels put out these “curtains of death,” each up to 50 miles long. Floating with the currents, they sweep up all sea life in their path. People wonder what the world would be without dolphins.

3 . More than 170,000 people in California are unhoused. Even as the state has poured resources into fighting against the problem, the number of people without homes has ticked upward in recent years. On the surface, the state has one key advantage for people without a reliable roof over their heads: relatively consistent and livable weather. So one of my first thoughts when I heard news of a horricane attacking Los Angeles was just “What will happen to the city’s homeless population?”
City agencies quickly took action. As it became clear that the Los Angeles region could experience an extreme downpour and subsequent flooding, outreach teams fanned out across the river bank and dam areas across the city that have become home to a significant unhoused population, offering support to move them into shelters and motels (汽车旅馆).
Despite that, it’s obvious that the effects of climate change will hit the most vulnerable (脆弱的) hardest. We see this globally as extreme weather events hit countries that have contributed the least to the problem.
The most notable connection between climate change and the US housing crisis is the threat extreme weather poses to unhoused people. More unhoused people are affected as climate change drives increasingly unpredictable weather. People without homes know how to respond to expected seasonal events. But events like a near-hurricane in Los Angeles or a wildfire in ‘Maui can catch populations with limited access to information off guard.
Another link worth considering is the way in which climate change creates more homelessness and further stresses on housing systems. Hurricane Katrina, for example, displaced 800, 000 people. Four years later, 12,000 people remained without shelter.
Housing has been — and will continue to be — a key issue in Maui too as it recovers from the wildfire that killed more than 100 people. Maui has already had a housing crisis, the result of a high cost of living driven in large part by the tourism industry. And, now, many more are left looking for places to stay. Ashley Kelly, the chief operating officer at Hawaii’s Family Life Center, said: “Finding housing for any new clients is just not possible right now.”

4 . As AI becomes popular, researchers have noticed its influence on the environment. Training an AI system requires huge computing power and electricity, and the resulting CO2 emissions (排放) are one way AI affects the environment. But its environmental effect is more than its carbon (碳)footprint.
Jesse Dodge, a scientist at the Allen Institute, says, "The influence of Al systems is going to be from their applications, not the cost of training them." David Rolnick, a computer scientist at McGill University, compares AI to a hammer (锤子) “The main effect of a hammer is what is being hammered,” he says, "not what is in the hammer." Just like a hammer which can either destroy things or build a house, Al can hurt or help the environment.
In 2019, ExxonMobil, an oil company, said it would use Microsoft’s app Azure. With the Al technology, it would increase its production and create billions of dollars. This means Microsoft's AI is directly contributing to greenhouse gas emissions. This is not the only AI application that could be environmentally harmful. AI behind the ads that jump out on Instagram or Facebook pages pushes customers to spend more on products like clothes. This in turn causes more emissions through more production and delivery.
But on the other side of the coin, there are AI applications that can help deal with environmental problems, such as the destruction caused by hurricanes. One such application is xView2, a program started by a U. S. organization. It can recognize buildings damaged and people trapped in natural disasters, reducing danger and saving time for rescuers.
AI could be a valuable tool in the fight against climate change—if the Al industry can reduce its harmful climate effects. "Both AI and climate rules have roles to play." Rolnick says. When creating Al rules, he suggests considering its applications, emissions, and other production costs. Further, Dodge adds that those AI professionals should help set up some value systems to limit the technology's use.

5 . On the streets of Manhattan and Washington, D. C., in neighborhoods in Seoul and parks in Paris, ginkgo (银杏) trees are losing their leaves in reaction to the first gust of cold winter air. This leaf drop, gradual at first, and then sudden, carpets streets with golden, fan-shaped leaves. Scientists are documenting evidence of the event happening later and later, a possible indication of climate change. But the story of ginkgos is not the familiar one of human carelessness with nature.
Thanks to fossils found in North Dakota, scientists found a ginkgo has genetically similar ancestors dating back 170 million years to the Jurassic Period. “It almost went extinct. Then humans rescued it and spread it around the world. It’s such a great evolutionary (进化) and cultural story,” says Peter Crane, a ginkgo expert.
One theory for the decline of the ginkgo species began 130 million years ago, when flowering plants began spreading. They grew faster and attracted more pollinators (传粉者) than ginkgos. “It’s possible that ginkgos were elbowed out of the way,” says Crane. Already competing to survive, ginkgos began to disappear during a time of global cooling that began around 66 million years ago. By the time the last ice age ended 11,000 years ago, the remaining survivors were found in China.
Ginkgo trees are smelly. “My guess is that they were eaten by animals that liked smelly things. They then passed through their body and grew.” Crane says. Those same seeds may have helped ginkgo find favor with humans 1,000 years ago. Once cleaned of their outer layer, ginkgo seeds are safe to eat. It’s then, when the trees had long since disappeared elsewhere, that people in China may have begun planting them and eating their seeds. Then gradually ginkgos spread across the world. Now it’s seemingly naturally resistant to insects and high levels of air pollution.
Crane isn’t worried about its future, though: The popularity of the species will help it survive. “Though its status in the wild may be difficult to access, it’s a plant that’s unlikely to ever go extinct,” he says.

Last summer, Hilda worked as a volunteer with dolphin trainers at a sea life park. Her job was to make sure the tanks were free of any items so that the trainers could train the dolphins to fetch specific items. However, one day after cleaning, one of the dolphins, Maya, presented Hilda with a candy wrapper from the tank. When Katherine, the trainer, saw this, she blamed Hilda for her carelessness. Upset but not discouraged by this event, Hilda decided to do some spying on Maya.
The next morning, Hilda arrived at the park early. She put on her scuba gear (水下呼吸器) and jumped into the tank for her usual, underwater sweep. Finding nothing in the tank, she climbed out of the water just in time to see Katherine jumping in on the other side. After what happened yesterday, Hilda knew what she was doing. She watched as Katherine performed her underwater search, but Hilda wasn’t surprised when she surfaced empty-handed.
During the tank sweeps, Maya had been swimming playfully, but now the dolphin stopped suddenly and swam to the back part of the tank where the filter (过滤) box was located. She stuck her nose down behind the box and then swam away. What was Maya doing back there? Hilda wondered. She jumped back into the water and swam over to take a look behind the box, and her question was answered. Hilda then swam across the tank following Maya’s path and emerged from the water to find Katherine removing her scuba gear. As Katherine turned around, her mouth dropped open. There was Maya at the edge of the tank with a comb (梳子) in her mouth waiting for her treat.
“Maya! Where did you get that?” demanded Katherine, taking the comb and throwing her a fish. “I know where she got it,” declared Hilda climbing out of the tank with a handful of items still wet from their watery, resting place. “What’s all this?” Katherine asked, obviously confused.

A China plane struck a bird after taking off in Chengdu, Sichuan, and had to immediately return to the airport last October, and it wasn’t the first accident between an aircraft and a bird last year.
In fact, more than 20,000 wildlife strikes with aircraft were reported worldwide in 2023 — the vast majority of those animals being birds. The strikes can also include run-ins with bats or creatures on the ground, such as deer or turtles. Expanding wildlife populations, increases in number of aircraft movements, and a trend toward faster and quieter aircraft all have contributed to the increase in wildlife strikes.
Bird strikes are a hazard not just to commercial airplanes, but to all sorts of aircraft. However, historical data shows that damage is reported in a small percentage of incidents. Last year, 95% of the global strikes involved some kind of damage — and only 5% of those caused “substantial” damage.
Some of the most disturbing types of strikes can happen when one or more birds go into a plane’s engine, which might cause a lot of damage to the aircraft. The pilot would need to return to the airport or find a safe place to land.
In last October’s China plane incident, the Beijing-bound flight was able to land normally in Chengdu after taking into account what the airline described as security concerns. Senior captain Chen Jianguo said pilots are trained on how to respond if they have a bird strike in flight. The pilot in this case did exactly what he was trained to do.
“There are lots of things that are being used by airports to try to manage the habitat and birds around the airport,” said Chen Jianguo. Airports need to manage bird habitats to reduce or get rid of trees and plants that shelter birds, or address wetlands that can attract birds. Collecting data on what kinds of birds are involved in strikes is equally important so the risks can better be managed. Many airports also use audible signals to scare birds away, such as the sounds of fireworks.

9 . Reducing food waste is easy — just ask the students at a school in Wood bridge, America, who have become experts at sorting their lunchtime trash (垃圾). Since the fall of 2019, they have actively participated in a successful food-waste diversion program that not only saves money but also contributes to reducing the amount of trash that heads to landfills.
Actually, this program plays a crucial role in facing up to the challenges of climate change. By reducing food waste,the school minimizes the amount of trash sent to landfills, thereby reducing harmful methane emissions (沼气排放). The school’s program is making a significant impact. Each month, it moves over 1,300 pounds of food waste, resulting in an estimated reduction of 772 pounds in CO, emissions and the production of 180 kilowatt-hours of energy, according to Blue Earth Compost in America.
At school, when students are done eating lunch, they head to an appointed section — a row of desks, garbage cans and containers — where they sort their trash. Leftover liquids, such as juice or milk,are emptied into a big basin on the floor. The juice containers and plastic water bottles are placed into another container to recycle. Additionally, prepackaged, unopened snacks such as bags of carrots as well as produce such as apples and bananas are “rescued” and placed into a big basket with a handwritten “Donations” sign taped to it to send to the town’s senior center.
The benefits extend beyond environmental awareness. The program reduces trash-carrying costs as less weight goes into the trash bins,making it easier for cleaners to manage. The students also find this planet-friendly practice enjoyable and meaningful, considering it a small game that contributes to a bigger cause. This initiative proves that collective efforts, even on a smaller scale, can lead to significant changes, not only in waste reduction but also in educating a generation committed to preserving our planet.

10 . Farming is destroying the planet, but there could be a much more environmentally friendly way to feed ourselves: using renewable energy to turn carbon dioxide into food. “This is becoming a reality,” says Pasi Vainikka at Solar Foods, a company that is building the first commercial-scale factory that will be able to make food directly from CO2.
There can be no doubt that immediate attention to find greener ways to grow food is required. Conventional agriculture, including organic farming, causes damage to the environment in many ways. It requires a lot of land, leading to habitat loss and deforestation. It is also the source of a third of all greenhouse gas emissions and releases other pollutants. It isn’t very efficient, either. Crops typically transform less than 1 percent of light energy into usable biomass (生物量).
Instead, Solar Foods plans to avoid photosynthesis (光合作用) altogether, and grow bacteria that use hydrogen as their source of energy. At the factory, renewable electricity will be used to split water to produce hydrogen and oxygen. The hydrogen will be added to large containers, where the bacteria grow, along with CO2 and ammonia (氨气). The end result will be a yellow powder called Solein.
Solein is made of bacterial cells and is up to 70 percent protein. It can be used as an ingredient in all kinds of foods. “We are aiming at replacing animal-sourced proteins, which we think have the highest environmental impact,” says Vainikka.
Compared with plant crops, Solein will use 100 times less water per kilogram of protein produced, 20 times less land and emit a fifth as much CO2, according to Solar Foods. There are other benefits, too: factories could be situated anywhere in the world and production won’t be affected by weather conditions.
“With Solar Foods and other companies scaling up their systems, this is truly beginning a new era of agriculture,” says Dorian Leger at Connectomix Bio in Germany. “I think these trends are exciting and will help bend the carbon curve as well as lead to improved global food supply security.”
