2 . 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.

While there is growing consumer     1     (realize) of the environmental impact of fast fashion, can the same be said about fast furniture? The chairs and tables that fill many of our homes and everyday spaces are manufactured on a mass scale, and the cheaper items often end up     2     landfills.

According to the Environmental Protection Agency (EPA), in 2020 over 12 million tons of furniture     3     (throw) out in America and some into the forest illegally. Buying furniture can be     4     (incredible) expensive. Many of us switch over to cheaper, instant brands like IKEA,     5     manufacturers use materials harder to recycle, which is likely to damage the environment.

With growing calls for sustainability, many brands are announcing to change though it remains     6     (see) whether they will keep these promises. In     7     (it) current sustainability strategy, IKEA commits itself to using only recyclable materials in all its products in an effort to practice “circular” design and cut emissions to net-zero. The concept of circular design     8     (win) increasing concern up to now. In     9     circular system, furniture products would be designed to last longer and be fully recyclable, thus forming a     10    (close) loop (环).

5 . If you haven’t taken down your Christmas tree yet, no worries. Here’s an idea: have you ever thought about eating it?

Julia Georgallis has some recipes. Over the last five years, she’s been preparing carefully for Christmas dinners in London with a friend. “How can we make something sustainable around Christmas time? What can we cat? What’s the thing that no one eats and that somehow represents Christmas? And then we just decided on Christmas trees,” Georgallis says.

She turned it into a book, How to Eat Your Christmas Tree. And her idea is that it’s not that odd. Some people enjoy Christmas wine. Some people like to go shopping and most people can get behind saving the planet.

“What I aimed for this book to do, really, was to get people thinking about the odd ways that they can be more sustainable in their daily lives,” Georgallis says.

“Eating Christmas trees isn’t going to save any animals in danger or freeze any ice caps. But if we start to think about everything that we do as a whole, then that builds up, you know, and that helps,” she says.

Most of the recipes in her book use the needles from the tree. “You’d use the needles like a herb,” she says.

“And different Christmas trees kind of have different flavors. They’re quite subtle, but they do have different flavors. So fir (冷杉), which is a really popular choice of Christmas trees, gives people better feeling and atmosphere. And then you have pine, which is a little bit more delicate.”

A warning: some Christmas trees are poisonous if eaten — like cypress and cedars. And be sure your tree wasn’t sprayed with pesticides (杀虫剂) and other chemicals. “So if you have any doubt that your Christmas tree might not have been grown to eat, then maybe don’t eat it,” Georgallis says.

And, of course, don’t even think about eating your artificial tree!

So, with all those instructions and with the appropriate tree, what could we cook? Well, Georgallis’ book has all sorts of recipes for different foods and drinks. Let’s open up the world’s cuisine with simple ingredients!

8 . Researchers in Australia have identified enzymes (酶) in the body of certain beetle larvae (甲虫幼虫) that can degrade or break down plastic. In a study published in Microbial Genomics, they write that these “superworms” could help reduce plastic waste in the future.

“Superworms are like mini recycling plants, cutting up the polysyrene (聚苯乙烯) with their mouths and then feeding it to the bacteria in their stomach,” said Chris Rinke from the University of Queensland in Australia. “The breakdown products from this reaction can then be used by other microbes to create high-value chemicals.”

In the study, scientists divided beetle larvae into three groups, feeding one group wheat bran, one polystyrene and one nothing. Over three weeks, they monitored their growth. “We found that superworms fed a diet of just polystyrene not only survived, but even had marginal weight gains,” said Rinke. “This suggests the worms can get energy from the polystyrene, most likely with the help of their stomach bacteria.”

On the other hand, the plastic-fed worms gained much less weight and were overall much less healthy than the bran-fed ones, though better off than the starvation group. After three weeks, some larvae were also set aside to grow into beetles, according to the study. About 93% of the bran-fed larvae formed adult worms, while about 67% of the plastic-fed larvae and 10% of the starved larvae formed adult worms.

The researchers investigated the superworm’s stomach bacteria to find the specific enzymes linked to plastic degradation, writes Fionna M. D. Samuels for Scientific American. The enzyme that degrades the polystyrene appears to live with the stomach bacteria, not the worm itself.

Polystyrene is one of the most common plastics used today. But it’s not very chemically reactive, and breaking it down with industrial recycling methods takes high heat. So, researchers have been looking for plastic-degrading enzymes and bacteria for years.

Further research will still need to be done to figure out how to employ these worms, bacteria and enzymes in recycling facilities.

9 . For Cruz, who grew up in Peru’s mountainous region of Cuzco, fog represents a massive opportunity. As a boy, he had to hike for more than an hour every day across hills to collect water from the nearest source. But over time, he realized that during the rainy season, droplets of water would gather in the large leaves of banana trees. So one day he and his father tried to build a canal system with the leaves to collect water and it turned out a success. But afterwards, he moved to Lima at the age of 25.

There, shocked by the water shortages and expensive water supply that some of the city’s poorest residents were faced with, Cruz set up El Movimiento Peruanos sin Agua in 2005. The idea was to deploy the method he learned in his hometown on a larger scale, which would provide free, independently sourced and easily accessible water to those who needed it most. He began installing (安装) a traditional fog catcher model developed in the 1980s.

At the highest point of Los Tres Miradores, there is a curious set of large structures that resemble a fleet of ships in the sky. They are so-called “fog catchers”. Netted devices, made of high density Raschel polyethylene and spanning several meters wide, are lined up at the top of a misty mound and linked by a network of tubes that lead to storage containers. The 40 fog catchers there provide enough water for 180 families, whether to bathe, clean, drink or to irrigate crops on small garden patches.

Supporters believe that fog catchers have the potential to improve water supply for communities around the world among the ever-challenging circumstances. German researcher Lummerich says, “They are cheap, easy to construct.” In a world searching for water supply systems, it is one important puzzle piece that can make an essential difference locally.

However, there are some issues. For one, fog catchers require space, which is not always easy to come by in cities, let alone urban slums. At the same time, fog catchers must be properly cleaned and maintained to stay effective. Most crucially, appropriate climate conditions are required. Fog isn’t everywhere.

Earthquakes are one of the most destructive natural disasters. They can happen just about anywhere. Earthquakes cannot be stopped,     1     your chances of survival are much better if you know what     2     (do) when an earthquake strikes.

If you are in     3     building, drop, cover, and hold on. This     4     (be) the national standard for earthquake safety in the United States. The advice is to get next     5     a strong piece of furniture (家具) so that if a wall falls, it will create something     6     (call) the “triangle of life” to help you survive. Use your     7     (hand) and arms to protect your vital areas like your head and neck. Do not move     8     (immediate) unless it is safe to do so.

Remember that aftershocks are possible at any time and are     9     (likely) after a bigger earthquake. Take good care of     10     (you) when you leave the building.
