1 . 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.

4 . In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise. Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持续的) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.
Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains.
In addition, we are seeing great growth in the global markets for sustainable products such as palm oil (棕榈油) , which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions (排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development.
Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of growing population within the limits if this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.
1. The traditional business model is harmful because of the following EXCEPT that ____________.| A．it makes the world warmer | B．it consumes natural resources |
| C．it brings severe damage to forests | D．it makes growth hard to continue |
| A．cut public expenses | B．forbid carbon emission |
| C．develop public resources | D．encourage energy conservation |
| A．To introduce a new business model. | B．To compare two business models. |
| C．To predict a change of the global market. | D．To advocate sustainable development. |
5 . The Coral Sea is home to an amazing variety of turtles, sharks, whales, dolphins, large fish, birds, corals, plants, and many other species. Many of these species are endangered elsewhere in the world, but still survive in the healthy environment of the Coral Sea.
The Coral Sea is a large series of coral reefs located off the northeast coast of Australia. This area is three times larger than Australia’s famous Great Barrier Reef, which the Coral Sea borders.
The Coral Sea is one of the few coral reef environments that have remained largely undamaged by overfishing, oil and gas exploration and pollution. However, statistics show that coral reefs around the world are disappearing five times faster than rainforests. It is very likely that in the near future the Coral Sea will face the same threats to its existence.
The Australian government is currently looking at options for protecting the Coral Sea but has made no decisions. Environmentalists are pushing for laws to declare the Coral Sea area a marine protected area. This would mean a large “no-take zone” for fishermen, a no-exploration zone for gas and oil companies and a no-dump zone for pollution. This would make the Coral Sea a marine park larger than any in the world.
We can write letters to Australian leaders, Australian environmental protection agencies, and Australian friends, to let them know that people worldwide support this protection of the Coral Sea. To lose this last great marine wildness would be a loss for the whole world.

6 . Insect numbers have plunged (骤降) by half in some parts of the world due to climate change and intensive agriculture, a study has found. The combined pressures of global heating and farming are driving a “substantial decline” of insects across the globe, according to UK researchers. They say we must acknowledge the threats we pose to insects, before some species are lost forever. But preserving habitat for nature could help ensure vital insects thrive.
Lead researcher, Dr Charlie Outhwaite of UCL, said losing insect populations could be harmful not only to the natural environment, but to “human health and food security, particularly with losses of pollinators(传粉昆虫)”. “Our findings highlight the urgency of actions to preserve natural habitats, slow the expansion of high-intensity agriculture, and cut emissions to mitigate climate change,” she added.
Plummeting populations of insects around the world — a so-called “insect apocalypse” — have caused widespread concern. However, scientific data gives a mixed picture, with some types of insects showing sharp declines, while others are staying steady. In the latest study, the researchers pulled together data on the range and number of nearly 20,000 insect species, including bees, ants, butterflies, grasshoppers and dragonflies, at about 6,000 different locations. In areas with high-intensity agriculture and substantial warming, insect numbers have plunged by 49% and the number of different species by 27%, compared with relatively untouched places that have so far avoided the most severe impacts of climate change, according to the research published in Nature.
But the researchers said there was some cause for hope in that setting aside areas of land for nature created a shelter for insects, which need shade to survive in hot weather. “Careful management of agricultural areas, such as preserving natural habitats near farmland, may help to ensure that vital insects can still thrive,” said Dr. Tim Newbold, also of UCL.
Study researcher, Peter MeCann, added: “We need to acknowledge how important insects are for the environment as a whole, and for human health and wellbeing, in order to address the threats we pose to them before many species are lost forever.”

7 . Butterflies, a familiar sight around the world, are disappearing now.Over the past four decades, more than 450 butterfly species have been affected by threats from climate change. In the US alone, the monarch butterfly has seen a drop of 80%, from millions of them in the 1980s to only 29,000 in 2020; in 2017, scientists in Germany raised alarm bells after stressing that insects had decreased by more than 70% in 30 years.
As of now, there is no long-term data available to develop effective conservation strategies in those areas where the threat is particularly widespread. And long-term monitoring programs worldwide face a challenge—training locals as citizen biologists, which, although successful, requires significant and constant funding to cover wages.
In Ecuador, however, scientists have come up with a novel approach.In Yasuni National Park, they started a monitoring project where park rangers(护林员) were trained and then performed monitoring.The rangers were able to identify sampled butterflies with impressive accuracy-an 85% success rate-which is key to the success of these monitoring programs. The data gathered by the park rangers was so accurate that it did not significantly differ from data obtained by trained biologists in the area.
Other monitoring projects select individuals from the community to act as citizen biologists, so scientists may pull the plug on them when funding dries up. However, this study represents a long-term solution.Monitoring with an infrastructure (基础设施)already in place means that it can continue into the future regardless of funding.
"Our approach increases the possibility of constant monitoring in the long term by reducing costs such as lodging(住宿)and wages,"said lead author Maria Checa. "Furthermore, it also empowers(授权)local people, offers opportunities to public institutions to accomplish their environmental goals, and opens up possibilities for expansion into other highly threatened and important areas for biodiversity(生物多样性)conservation."

9 . When I give public lectures about the climate crisis, the most common question people pose is: “Are you an optimist or a pessimist?”
My answer is the former one. California has achieved significant emission (排放) reductions in a strong economy, which makes me hopeful, yet in general the fossil-fuel industry is determined not to change. The second most common question is: “What can I, personally, do?”
That’s a tough one. The major drivers of climate change are collective enterprises (集体企业) such as industry, large-scale agriculture and transportation systems. Real emission reductions in these settings most likely will not come from personal actions; they will come from laws and policies such as carbon-pricing systems, revised building codes and supports for green investment.
Some people have argued that calls for individual actions actually distract us from the responsibility of big companies. That could explain why the fossil-fuel industry is fond of such requests. Oil giant BP popularized and promoted the idea of a carbon footprint, turning attention to its customers who, it suggests, should take personal responsibility by lowering their carbon footprints. One study found that focusing on individual activity actually makes it harder for more effective policies such as a carbon tax to be carried out. Another problem with personal behavior is that people do not like to be told what to do.
Yet individual acts can grow into influential group activity. One effective act, and one that can be amplified (放大), is to eat less red meat. Cutting meat consumption is a powerful and personal thing most Americans can do to deal with the climate crisis, and they can do it immediately. About 40 percent of greenhouse gases come from agriculture, deforestation and other land-use changes. Meat — particularly beef — drives climate change in two ways: first, through cows’ emission of methane, a greenhouse gas, and second, by destroying forests as they are changed to grazing land (牧场) to satisfy the global demand for beef. By eating less beef, we can start to decrease that demand. You do not have to become a vegan to do this. If every person in the U. S. cut their meat consumption by 25 percent, it would reduce annual greenhouse gas emissions by 1 percent. That might not sound like a lot, but it would help protect the rainforest, so the positive effects — including reduced water and fertilizer use, improved biodiversity and safeguarded rights of local peoples — would be amplified.
Perhaps most important, social action is contagious — in a good way. If lots of us begin to eat less meat and if we talk about it constantly, we are likely to influence others. Pretty soon the 1 percent reduction becomes 2 percent or more. Reduced demand for meat could motivate my local supermarket to carry better produce, making it easier for me and my neighbors to prepare a few more satisfying meat-free meals. In the end, changes in demand will influence industry. Forty years ago few mainstream supermarkets carried organic products; now nearly all do. Consumer demand did that.
Cutting back on red meat also has the added benefit to your health. So while I wouldn’t advise governments to order people to stop eating hamburgers, if anyone asks, “What can I do?” a simple answer is: “Eat less meat. It’s in your control, and you can begin right now. It benefits both you and the planet.”

10 . When Abdus Salam looks across the garbage-filled river near his home in one of the major clothing producing districts in Dhaka, the capital of Bangladesh, he remembers a time before the factories moved in. “When I was young there were no clothing factories here. We used to catch fish in the river,” he said. The river beside him is now black like ink. Waste from nearby clothing factories has polluted the water.
Fashion is responsible for up to one-fifth of industrial water pollution, thanks in part to weak management in producer countries like Bangladesh, the world’s second biggest clothing producing country, where wastewater is commonly differed directly into rivers and streams. The wastewater not only hurts the environment, but pollutes drinking water sources.
Once in waterways, poisonous chemicals from dye (染料) build up to the point where light is prevented from coming through the surface, reducing plants’ ability to photosynthesize (进行光合作用). This lowers oxygen levels in the water, killing plants and animals. These chemicals and heavy metals can also build up in the body, increasing the risk of serious illnesses and skin problems. What’s worse, chemical-rich water is also used to water crops, with one recent study finding that dyes were present in vegetables and fruit grown around Savar, just north of Dhaka.
Luckily, change is coming. In Bangladesh, there are signs clothing producers are taking environmental responsibility more seriously, with brands committing to initiatives, such as the Partnership for Cleaner Textile, that title water, energy and chemical use in the industry. Shahab Uddin of Bangladesh’s Ministry of Environment, Forest and Climate Change said a range of measures were being taken to address pollution, including updating conservation and environmental laws, giving fines to polluters, setting up centralized treatment plants, and working with international development partners to improve wastewater treatment. And under a new environmental policy called Zero Liquid Discharge, dyeing, finishing and washing industries must submit a time-bound plan to reduce, recycle and reuse wastewater.
“There is definitely from for further improvement. These challenges cannot be solved overnight,” Uddin added.
