1 . 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.

2 . 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.”

3 . 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."

4 . 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.”

5 . 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.

6 . I recently gave a talk about zero waste living to university students. During the Q&A afterward, the unavoidable question of cost came up. One student pointed out that he “can’t afford to buy $30 toothpaste.” While the $30 price may be a bit generous, the student did raise a good point that buying zero-waste products is often more expensive than the overly-packaged traditional ones.

I tried to handle the question as best I could in the moment, but I kept thinking about it afterward. I’m writing about it because I’m sure many others have similar doubts about their own abilities to reduce waste without breaking the bank.

First, once you begin to explore the zero waste world, you quickly realize how pointless many products in your life are. You start using fewer, buying less, and using them interchangeably. Soon you’ll find yourself spending less money overall, which balances the higher cost of the zero waste ones. The total number of products in my bathroom decreased by 50% when I became more focused on waste reduction.

Second, if you stop to examine those zero-waste products, you’ll see that they are usually of better quality. Companies usually redesign their packaging to be reusable, upgrading them to be healthier, safer, and greener. So you’re paying extra money not just for non-disposable (非一次性的) packaging, but also for a better product that does less harm.

In my experience, higher-quality skincare products last longer than cheap ones. My personal habits have developed gradually, too. Knowing an item costs more leads me to use it in small quantities and use it to the very end. Moreover, I sometimes even make my own. The price-per-unit is cheap.

To quote Lindsey Miles, a zero waste blogger, “Zero waste is not about what we can afford to buy. It is about what we choose not to buy.” To that student who got me thinking about this, I’d recommend starting with what matters to you. Over time you will figure out where you get the most value for your money. In return, you’ll gain a sense of liberation from the consumer culture, and a rewarding sense of accomplishment.

7 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Nowadays, people are understanding the need to solve the climate and biodiversity problem. Poor ecosystems, forest fires, Covid-19 and more extreme weather events are showing us that the     1     (destroy) of the natural world is greatly impacting on the planet.     2    , it is time to take action.

Rainforest Concern       3     (establish) in 1993 aims to protect endangered natural habitats, the biodiversity they contain, and the people who depend on them for their survival. For over 20 years, Rainforest Concern     4     (protect) threatened cloud forests in north-west Ecuador, within the global biodiversity hot spot,     5     contains one-sixth of all plant life on the planet.

One of the most immediate threats to the bio-region is heavy industry, resulting in polluted rivers and the disappearance of hectares of forest, massively impacting on     6     (region) climatic conditions and     7     (potential) putting even more species on Red List.

To protect the cloud forests from threats, Rainforest Concern supports community reserves and has created a private reserve,     8     (focus) on forming ecological passages to connect existing protected areas. These measures are all helping to protect the weak cloud forest ecosystem from     9     (damage) and stop the reduction of its wildlife. But it takes money to keep going, and     10     more human pressures on the region, threats are increasing, and the forests and our planet are running out of time.
