1 . Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.
But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.
Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.
Twenty –five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” says Bruce Anderson.

2 . In the northernmost edge of Colombia sits the coastal town of Acandí. Access to the town is only by water or air; there is no road that leads there. The residents there are faced with the struggles of balancing livelihoods while protecting biodiversity.
In the past, traditional community fishing methods, passed down by the elders, focused on the reasonable fishing and management of resources. However, the introduction of large-scale trawling vessels(拖网渔船) decades ago gradually depleted the area’s fishing resources, leading to damage to marine(海洋的) life seriously.
Jesús Antonio Julio Cuestas, who serves in the region’s conservation and management of marine resources, stresses the bad impact of these developments and calls for new fishing techniques. “Fishing and conservation co-exist as long as we have good management practices and reasonable use of our fishing resources,” says Cuestas. He and other officials actively monitor fishing activities in Acandí. Each morning, they visit the fish markets to gather data on fishery resources—including prices and sizes—to monitor the state of the local fishing industry.
Along with Cuestas, the fishers work to reduce their impact on the marine ecosystem. By changing fishing methods and adopting new practices, they aim for a more balanced approach to fishing. “This year the local fishermen have not used the trawl net s that were causing the death of the leatherback sea turtles,” explains Cuestas proudly. Changes include the efforts of boats to protect the seagrass that serves as feeding grounds for marine life and an end to fishers throwing net s where turtles lay their eggs.
This marine reserve in Acandí, Cuestas believes, is their greatest treasure. He attaches great importance to working together with local residents to improve the quality of life while preserving the marine ecosystem. By doing so, he imagines a picture where individuals from the fishing community can pursue various careers, such as engineers or lawyers, proudly stating that they are the products of the fishing tradition in Acandí.

4 . Growing up, my grandparents bought a second home among a small forest in Arkansas and would bring me there every single summer. I would spend a lot of time outside there following my grandfather around while he did yard work. We would collect cool-looking rocks and refill the hummingbird feeders.
I always remember my grandparents calling me over to the window when a deer family was in the yard or a few hummingbirds were at the feeders so that I could watch them. I would explore around in the yard by myself sometimes to look for interesting rocks and if I was lucky I would find a turtle. If I did find a turtle, my grandfather would put it in the kiddy pool for me to observe for a few minutes. I was always amazed by these creatures. After I finished observing the turtle, my grandfather would pick it back up and return it to the bush I found it in. I would watch in amazement as it slowly stuck its legs out and crawled back under.
I always felt very at peace at my grandparents’ home. It was quiet and full of interesting natural things I never got to see in Illinois. They disturbed the land around them as little as possible and didn’t see it as nuisance (令人讨厌的东西), rather a beautiful view.
As Aldo Leopold, an American scientist, puts it, we should take the time to appreciate and observe the natural world around us. When we do this, we find it brings us happiness and has a great value beyond just that of resources. Conservation(n.保护) of the natural world is important because we are dependent upon it for life. We cannot worsen such a bountiful provider at such a rate in which it will never return to anything like what it once was. Our experiences with nature are what will drive us to reach this conclusion, if only everyone took the time to really involve themselves in it.

5 . Masks that helped save lives are proving a deadly danger for wildlife, with birds and sea creatures trapped in the shocking number of thrown-away facial coverings. Single-use masks have been found around pavements, waterways and beaches worldwide. Worn once, the thin protective materials can take hundreds of years to decompose. “Face masks aren't going away any time soon—but when we throw them away, these items can harm the environment and the animals,” Ashley Fruno of animal rights group PETA said.
In Britain, a gull was rescued by the RSPCA after its legs became tangled in the straps of a mask for up to a week. The animal welfare charity took it to a wildlife hospital for treatment before its release.
The biggest impact may be in the water. More than 1.5 billion masks made their way into the world's oceans last year, accounting for around 6,200 extra tonnes of ocean plastic pollution, according to environmental group Oceans Asia.
Conservationists in Brazil found one mask inside the stomach of a penguin after its body was washed up on a beach, while a dead pufferfish was discovered caught inside another off the coast of Miami. French campaigners found a dead crab trapped in a mask near the Mediterranean. Masks and gloves are “particularly problematic” for sea creatures, says George Leonard, chief scientist from NGO Ocean Conservancy. “When those plastics break down in the environment, they then enter the food chain and impact entire ecosystems.” he added.
There has been a shift towards greater use of reusable cloth masks as the pandemic has worn on, but many are still using the lighter single-use varieties. Campaigners have urged people to bin them properly and cut the straps to reduce the risk of animals becoming trapped. Oceans Asia has also called on governments to increase fines for littering and encourage the use of washable masks.

6 . Chinese scientists say they have developed a robotic fish that can remove microplastic particles from water environments. Researchers working on the project say the robots could help to clean up plastic pollution in oceans around the world.
The robotic swimmers are about 1.3 centimeters long. They are made of a soft chemical Compound. The robots are designed to absorb microplastics while moving through the water. The project was launched by a team at Sichuan University in southwestern China. The researchers said the robots have already performed well in shallow water and they plan to carry out more tests in deeper waters. The scientists reported their findings in a new study in Nano Letters. The publication comes from the American Chemical Society, a nonprofit organization supported by the U.S. Congress. The robotic fish were built to target microplastic particles, which are smaller than five millimeters. Studies have confirmed that microplastic pollution has been discovered in many natural environments. The material comes from the breakdown of manufactured plastic products and industrial waste.
The team said the robots can be controlled by light. Turning “a near-infrared light laser” on and off causes the fish’s tail to move back and forth, the American Chemical Society said. The robotic fish can swim up to 2.76 body lengths per second. The researchers said this is faster than most similar soft robots. Wang Yuyan was a member of Sichuan University’s research team. She told Reuters news agency that the small, lightweight robot is currently being used to collect microplastics for research purposes. But Wang added that the team plans to expand that use so the robot fish can remove larger amounts of microplastic waste from deep ocean areas. The fish can take in different kinds of microplastics and even repair itself when damaged, the researchers said. And if a robot fish is accidentally eaten by a real fish, it could safely digest the material, the team added. Wang said similar robots could be developed to be placed inside the human body to remove unwanted materials or disease.

7 . Coral reefs in Florida have lost an estimated 90% of their corals in the last 40 years. This summer, a marine heat wave hit Florida’s coral reefs. The record high temperatures created an extremely stressful environment for the coral reefs, which are currently also experiencing intense coral bleaching (白化).
A coral is an animal, which has a symbiotic relationship with a microscopic algae (藻类). The algae gets energy from the sun and shares it with the coral internally. The coral builds a rock-like structure, which makes up most of the reef, providing homes and food for many organisms that live there. Coral bleaching is when the symbiotic relationship breaks down. Without the algae, the corals appear white because the rock skeleton becomes visible. If the bleaching continues for an extended period, the corals can starve to death without the energy.
Florida is on the front lines of climate change. It is also on the cutting edge of restoration science. Many labs, institutions and other organizations are working nonstop to protect and maintain the coral reefs. This includes efforts to understand what is troubling the reef, from disease outbreaks to coastal development impacts. It also includes harvesting coral spawn (卵), or growing and planting coral parts. Scientists moved many coral nurseries into deeper water and shore-based facilities during this marine heat wave. They are digging into the DNA of the coral to discover which species will survive best in future.
There are some bright spots in the story, however. Some corals have recovered from the bleaching, and many did not bleach at all. In addition, researchers recorded coral spawning. Although it’s not clear yet whether the larvae (幼虫) will be successful in the wild, it’s a sign of recovery potential. If the baby corals survive, they will be able to regrow the reef. They just have to avoid one big boss: human-induced climate change.

9 . Buildings, pollution, poor soil, insects, and even car crashes can add to tree loss. However, between 2016 and 2021, the city of Seattle in Washington state was reported to have lost about 255 hectares of tree covering, for which climate change was blamed. Then came the driest summer on Seattle’s record books in 2022. The drier conditions and hotter temperatures have left many trees with brown leaves, naked branches, and extreme seeding. These are all signs of tree stress.
According to Nicholas Johnson, a tree expert for Seattle City Parks, if this warming climate continues we are going to have a lot of trees die. Just like people, under the heat trees get weak.
Researchers from France and Australia studied the effect of hotter temperatures and less rain on more than 3,100 trees and plants in 164 cities across 78 countries. They found about half the trees in the cities were experiencing climate conditions beyond their limits. They also found that by 2050 nearly all trees planted in Australian cities will not survive.
It’s not the gradual change but these extreme swings of too much water, too little water, too much wind, and terrible storms that are going to cause these rapid changes. In 2005, Hurricane Katrina destroyed about 10 percent of the trees in New Orleans, Louisiana. And in 2021, Hurricane Ida uprooted many new tree plantings.
To settle the problem of tree loss, non-native trees have been brought to cities for some time. In the city of Bellevue, Washington, experts are growing different kinds of trees specifically for climate change. On city grounds, they are planting baby giant sequoias, just a few centimeters tall. The giant sequoias are not native to the Pacific Northwest area. But the trees can deal with the lack of rain and insects. Once these trees are established, they grow incredibly fast. Having many different kinds and ages of trees is important to keeping urban forests alive.
“Life always finds a way,” said Nicholas Johnson. “And in Seattle, people are helping life find a way.”

10 . During the COP27 climate conference (会议) in Sharm el-Sheikh, Egypt, an important deal on “loss and damage” was reached. This was a big step forward because at COP26 conference in Glasgow, Scotland, there were no talks on loss and damage at all. The plan is that richer countries will pay money into a special fund that will be used to help poor countries.
Loss and damage means the damaging impact of climate change on developing countries. For nearly 30 years, poorer countries have been asking richer countries for money to help to protect communities from the effects of climate change. Richer countries have produced the most greenhouse gases, but poorer countries are often the worst affected by extreme weather conditions because they are less well equipped to face extreme climate events.
Brazil’s newly elected President Luiz Inacio Lula da Silva made a speech about preserving the largest rainforest on Earth, the Amazon. During the last 50 years, more than 17% of the Amazon rainforest has been destroyed to make way for farms and towns. However, in his speech, Lula promised that there would be zero deforestation (伐树) in the Amazon by 2030. The conference didn’t just focus on world leaders. It brought together more than 45,000 people to discuss how climate change is affecting their lives. Climate refugees (难民) also had their voices heard. Tshilombo from the Kakuma refugee camp in Kenya said, “Refugees don’t only flee because of war or conflict. It’s also about drought, the effects of climate change.”
Some countries weren’t happy with the overall outcome of COP27 because decisions weren’t made on cutting the use of fossil fuels, such as coal, gas and oil, etc. The UK Government’s Alok Sharma said, “I’m incredibly disappointed.”
However, this deal was a great achievement for developing countries. Sherry Rehman, the climate minister for Pakistan, said, “I am confident we have tuned a comer in how we work together to achieve climate goals.”
