1 . The Internet’s carbon footprint is as bad as air travel. While it is difficult to measure precisely, estimates place it at over two percent of global greenhouse gas emissions(排放)—the same as the air travel.
Information may appear to spread around the world unseen to our eyes, but it actually passes through enormous data centers placed strategically about the globe, which store, organize and deliver everyone’s data. These centers are extremely energy intensive. In the EU, they consume close to three percent of its total energy usage and also require lots of water to prevent their computers from overheating. In the US, about a fifth of data centers draw water from already stressed water sources.
A typical spam email(垃圾邮件)emits around 0.03g of CO2 emissions, though longer messages read on a laptop can go all the way up to 26g. Now multiply that by 333 billion(roughly the number of emails that get sent every day in 2022). That puts all those work emails into perspective. One study found if every British adult sent one less “thank you” email a day, it would save 16, 433 tons of carbon a year. It even predicted that the ICT industry could account for up to a fifth of the world’s energy consumption by 2025.
However, there are measures that we can take to reduce our digital carbon footprint. For instance, you can unsubscribe from marketing and other spam emails and only subscribe to newsletters that you still regularly read. Have regular data checks where you delete old contact lists and other documents that no longer have any use. Keep a clean inbox and delete emails you no longer need.

2 . Sea life near Turkey is being harmed by a layer of brown foam (泡沫) on the ocean’s surface. The foam, which many people are calling “sea snot”, is natural, but it’s caused by pollution and global warming.
The actual name for the foam is mucilage (粘液). Scientists first noticed and described mucilage in 2007, when it was found near Turkey. Then, it was also found in other parts of the Aegean Sea, near Greece. Mucilage covers the ocean’s surface with a thick, slimy layer that gives it the nickname of sea snot.
This year’s appearance of mucilage is the worst ever recorded. It’s been developing for seven months and is now covering large parts of the Sea of Marmara. The Sea of Marmara is an inland sea, surrounded by land belonging to Turkey, and connected to the Aegean Sea and the Black Sea.
There are many different kinds of algae (海藻), and it’s natural and normal for algae to grow in the ocean or in other bodies of water. But when there is lots of food for the algae, and other conditions are just right, algae would boom, which results in algae growing quickly and in huge numbers. And in very bad situations, mucilage is the result.
There are two main causes of the present appearance of mucilage. One is the heavy pollution — waste water and chemicals — flowing into the Sea of Marmara. The second cause is higher water temperatures because of climate change.
By covering the ocean’s surface, mucilage stops sunlight from reaching all the sea life below. “This mucilage is now covering the sea surface like a tent,” says Muharrem Balci, who teaches biology at Istanbul University. Because there is so much algae, it takes up lots of oxygen from the seawater. That means that there’s very little oxygen left for the other sea life that depends on it. The BBC reports that divers in the area are seeing large numbers of dying fish. After a while, the mucilage falls to the bottom of the ocean, where it covers the sea floor, poisoning sea life that lives there. The mucilage has already been found as deep as 30 meters below the surface.
Mahsum Daga, a local fisherman, told the reporter, “Do you know what it does to shellfish? When they open up, it prevents them from closing up again because it gets in the way. All the seasnails here are dead.”

3 . Dairy (奶品场) packaging has been changing a lot for so many years. Now, businesses are using technology to create more sustainable (可持续的) packaging options along the whole supply chain.
Ian Olmstead, program manager at Dairy Australia, says, “We’re trying to make sure the plastics we use are designed in a way that allows them to be recycled. Then we have partnerships in place that support the processes for recycling, and seek to increase the food-grade recycled content that can be used again in dairy packaging.”
Brownes Dairy — Australia’s oldest dairy has worked with Tetra Pak to make its next change. Brownes’ senior marketing manager, Nicole Ohm, says it has been important to create a product that not only is recyclable, but starts life in a sustainable way, too. “The start of life is just as important as the end of life,” she says. “Being able to make an effective change at the start of life just makes for a greener result.”
Milk packaging is made of three covers. Recyclable cardboard sits in the middle, with polyethylene (聚乙烯) plastic on both sides acting as a protection. Historically, these outer covers have been made from plastic, but Brownes’ new packaging will use a renewable resource: sugarcane, a kind of plant. “The plant-based protections behave in the same way,” Ohm says, “and so does the recyclability.” “Being Australia’s oldest dairy carries a level of responsibility,” Ohm says. “Even though we are very old, we are not at all traditional—we are very advanced.”
When it comes to plastic packaging, the dairy industry faces many challenges. Recyclable material must be food safe, for example. And one plastic milk bottle might contain a number of different plastics, from the bottle itself to its cover. Even the glue on the label becomes part of the recycling challenge that needs to be got over.
Dr Stephanus Peters is a managing partner at PEGRAS, a global technical solutions consulting company. Peters explains the problem PEGRAS has been asked to solve: make it easier to take away non-recyclable parts from milk bottles to avoid pollution. “You always have a little bit of glue left,” he says. “We have to take away the glue before the bottle can be recycled. If successful, this advance could be used in every industry.”

4 . Most people have already heard we are facing an era of massive species extinction, that we run out of insect pollinators (传粉者) for our plantations and that springs are silent now. It is also agreed that a diverse nature is essential for our economic and emotional well-being and for human health. But how to achieve this?
Buildings produce dangerous emissions (排放物) polluting the air. The nation’s buildings are responsible for 40% of all US carbon emissions. Designing buildings that put the environment first is essential. Daniel Jaconetti, the National Sustainable Design Leader for the architecture firm HED tells Gb&d Magazine, “Our first responsibility is to educate and then to design for clients the best possible building that meets their needs.”
The best buildings are designed to be resilient (能复原的) , energy efficient, comfortable, and without poisonous chemicals. They are probably the ones-that make the most sense to people—being as efficient as possible. “You’re putting out fewer emissions.” Daniel Jaconetti tells Gb&d.
Eco-conscious design can be found-in a number of ways. The application of solar power is just one common design trend. Choosing eco-friendly building materials can also help. This can include a wide variety of materials, from bamboo to those recycled.
When looking for ways to cater to eco-friendly design, biophilia (热爱生物) has been used in architectural design to unite nature into the environment. With common elements of biophilic design in buildings including indoor trees and plants and living walls creatures, we can enjoy the various benefits associated with the presence of nature indoors. For already constructed homes, biophilic design element can help create an environmentally friendly atmosphere. Bringing in plants is just one major way to make an eco-friendly statement. Properly styling the greenery can be the difference between showcasing the tree itself and allowing it to complement the surrounding design.

6 . The ocean covers more than 70 percent of the earth’s surface and the deep sea could contain as many as 100 million species. But it’s becoming worse. Overfishing, plastic pollution, rising sea levels, and climate change are to partly blame (责怪) for the ocean’s present state.
People are talking about plastics more than ever after recognizing the heavy effect the material has on our planet. Every year, thousands of seabirds, sea turtles, seals, whales, dolphins, and fish are killed after mistakenly eating plastics.
Keeping our coastlines clean is a simple way to help the planet. After a day at the beach, make sure you’ve taken everything with you, including rubbish.
Being mindful of what cleaning products you use is another effective way to reduce your effect on the earth. Chemicals like household cleaners can move through waterways and eventually end up in the sea, affecting the health of oceans and the animals in them.

7 . A powerful earthquake hit Morocco on Friday night, killing over 2,500 people and causing huge damage over a large area. The quake was one of the most powerful ever recorded in Morocco. It’s also the country’s deadliest earthquake in over 60 years. So far, the earthquake is reported to have killed over 2,680 people. It has injured over 2,500 others. The earthquake was especially dangerous because it happened at night, when people were asleep in their homes.
Marrakesh is a big city that’s popular with tourists. Many of its modern buildings seem to have survived the earthquake, but the old part of the city, Medina, was hit hard. It has buildings that are over 1,000 years old. Many of those buildings were demolished.
Outside of Marrakesh, the earthquake caused even more damage. In the Atlas Mountains, the earthquake’s center, there are many small villages, some of which were nearly destroyed.
Many of the people in the area live in simple houses made of mud bricks, which is a traditional way of building in Morocco. But it’s not strong enough to protect against earthquakes. Although the Moroccan government has laws that require buildings to be built more safely, these rules are often ignored.
Rescue workers have been working hard to save those affected by the quake. In larger cities, rescue efforts seem to be going well. But it has taken a lot longer for help to reach remote areas in the mountains. Many of these villages are difficult to get to. The earthquake caused landslides, blocking roads, and making these places even more difficult to reach. In some areas, phone and electrical service were also knocked out, leaving these places completely cut off. That means that the local people in some remote areas have had to deal with the situation on their own. In some areas, people have been digging through the broken stones or bricks with their hands, trying to find survivors. Many people are sleeping outside, unsure if their houses are safe.
Many outside countries have offered to help Morocco. Some countries have offered teams of experts; others have offered supplies.

8 . How to prepare for a wildfire
Before you can effectively prepare, it’s very important to understand how wildfires operate. Many think wildfires destroy homes because a wall of flames(火焰)moves across the landscape.
Creating a defensible space around your home acts as a barrier against wildfire flames. Home hardening involves constructing with fire-resistant materials. Investing $10,000 to $20,000 in these measures significantly reduces the chance of a home being ravaged by a wildfire, lowering risk by 75%.
Remove dead tree branches
Similar to dry or bagged leaves, dead tree branches are dry, which means they, too, can catch fire quickly. If you have any hanging from trees or laying in your yard, remove them ASAP. The same rule applies when removing dead tree branches:
Create an evacuation (撤离)plan
Families should go over an evacuation plan and practice it well before an emergency actually occurs. Knowing when to leave and being able to go quickly is crucial during an evacuation scenario.
Make sure gutters(水槽)are made of metal

9 . The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by S02 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must care about the rise in pollution at the same time.

| A．Many countries are making rules to fight pollution. |
| B．The problem of pollution is not so serious because there are not so many people living on the earth. |
| C．The pollution of the earth grows as fast as the world population does. |
| D．If people could go to work by bus or bike instead of car or motorbike, it would be helpful in fighting against the problem of S02. |
10 . It’s just past 7 a. m. on a February morning in Maya Bay, several weeks after authorities reopened what is one of Thailand’s most popular tourist attractions to the world for the first time since June 2018 following a massive restoration program.
In the hours to follow, a slow but steady flow of tourists becomes in great numbers as dozens of tourists make their way to the white-sand beach, phones at the ready as they take photos. Swimming is not allowed, though visitors can take a few steps in. It’s disappointing, but a huge improvement over what visitors once experienced here.
Maya Bay is located in a Thailand’s national park. The destination was made famous by the 2000 film The Beach, starring Leonardo DiCaprio. As the film’s popularity grew, so did tourists’ desire to visit the location where much of it was shot —Maya Bay.
“Around 40 years ago, Maya Bay was already a tourism destination, but mainly for Thai tourists because you didn’t have speedboats at that time,” says Thon, a marine biologist and professor who requested authorities to close the bay four years ago. Over the years, the number of tourists rose from less than 1, 000 to as many as 7, 000 or 8, 000 visitors a day at its peak. On average, around 5, 000 people entered the bay each day.
In 2018, the Thai government closed the bay and began to restore the damaged ecosystem. Since then, Thon and a team of fellow marine experts and volunteers have replanted over 30, 000 pieces of coral, much of it grown off the coast of a nearby island. Meanwhile, the wildlife also returned and has been growing. “Only three months after we closed the bay, the blacktip sharks came back and gave birth… so there are a lot of things happening in Maya Bay.”
