Protecting the Wild Animals
_______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________3 . 400 million tons of plastic are generated annually, most of which comes from single-use plastic While countries are making progress in reducing this waste through paper bags and straws, there are still applications where the properties of plastic are necessary.
Transparent (透明的) wood is an alternative for such applications and is highly preferred since it prevents the harm of petroleum-derived (石油衍生的) plastic products. German scientist Siegfried Fink first created transparent wood in the year 1992, and over the past three decades it has been significantly improved by other researchers as well.
In its natural form, wood is not transparent. However, researchers have found that removing lignin, a naturally occurring biopolymer that provides structural support for the plant tissue, can make it transparent. To do so, the wood is soaked in a warm solution consisting of multiple chemicals, followed by boiling it in another solution. This removes the lignin completely and turns the wood white. However, the space that was occupied by lignin needs to be filled up to maintain structural integrity. This process is done by using a resin (树脂) at a temperature of 185 Fahrenheit (85℃).
The final product can have as much as 90 transparency, and it doesn’t break easily. More importantly, it is more biodegradable than glass or plastic.
While transparent wood isn’t commercial yet, it has been employed in a wide variety of applications ranging from construction to energy storage, making flexible electronics and packaging.
The researchers at the Indian Institute of Technology ( IIT) conducted a life-cycle analysis (LCA) of transparent wood to determine the environmental impact of its production and end-of-life (EOL) cycle. The study found that using hydrogen peroxide for delignification, followed by using epoxy for infiltration, was the most eco-friendly. When scaled up for industrial production, the former method would lower electricity consumption by as much as 98. 8 percent.
EOL analysis showed that transparent wood had a reduced ecological impact compared to polyethylene (聚乙烯), paving the way for it to be commercially adapted to replace the petroleum-based material.

4 . Barcelona’ s opera house has celebrated its reopening to the public since the corona-virus pandemic (新冠疫情) put the world into a huge horror, but their opening night had an unusual audience. For its first concert, the theater refused the usual crowd of people and instead packed the house with plants. Yes, that’s correct. All 2, 292 seats at the Gran Teatre Liceu were occupied by leafy green plants.
The idea was conceived by conceptual artist Eugenio Ampudia and was broadcast live on the theater’s website. These lucky ficus trees, palms, and Swiss cheese plants, which were brought in by local nurseries (苗圃), got the pleasure of hearing Puccini’s Crisantermi performed by the UceLi Quartet string musical group.
Ampudia hopes that his idea and the work will inspire people to think more deeply about their relationship with nature and the concept of sustainability (持续性). “We are at the end of an era and that means that we have to change certain patterns,” he shares. “We don’t live in the same world as 90 days ago, and this means we have to reflect on everything that we do.”
As plants can respond to different vibrations (震颤) caused by music, they certainly weren’t a passive audience, even if they weren’t able to give applause. Now that the concert is over, each plant will be given to a different frontline healthcare worker who helped guide the country through its battle with the corona-virus.
The moving concert is a continuation of the Liceu’s mission to create a dialogue between music and the visual arts. Pictures and a video of the performance taken by Ampudia will now become part of La Caixa contemporary art collection.

5 . In recent years, studies have suggested how the bisphenol A (BPA) in some food-packaging plastics has been linked to various health problems including heart disease and developmental difficulties in children. Scientists are thus developing a more harmless alternative, and it’s made from tomato waste which would otherwise be got rid of.
However, BPA is still widely used in the plastic coatings which are applied to the inside of metal food packaging such as cans. These smooth waterproof coatings help protect the metal from corrosion (腐蚀), plus they keep the food from sticking to the inside of the container.
Building on previous studies, an international team has researched a type of agricultural waste known as tomato pomace. This material typically consists of tomato skins, seeds and stems, which are left over after the fruits have been processed for use in foods such as sauces or juices. Ordinarily, the pomace is simply dumped in a landfill, burned, or at best composted. It may also be used in animal feed, although it doesn’t have much nutritional value.
The scientists started by drying tomato pomace — first in the sun for three days, then in a 60℃ oven for 16 hours — after which they grounded it into a powder. That powder was subsequently mixed with a sodium hydroxide solution (溶液), which was then heated at 100℃ for four hours. After repeatedly filtering that solution to remove the sodium hydroxide, the researchers were left a lipid. That lipid was then mixed into an ethyl alcohol solution which was sprayed onto samples of some metal. Once the spray had dried and the samples had been heated in a 200℃ oven for 10 to 60 minutes, the result was a polymerized lacquer coating which proved to be very effective at protecting the metal.
The scientists now plan on testing the coating on actual cans. “We would take tomato sauce, and other foods that are usually sold in cans, and we would sterilize them, put them in tins and check if they withstand real conditions,” said a scientist.

7 . California has been using recycled wastewater for many years. A team has used it to make ice surfaces for the game of hockey(冰球运动). It has been used to make snow for the sport of skiing. And farmers use it to water their crops. But it has not been used directly for drinking water.
Recently, California officials approved new rules to let water agencies recycle wastewater and put it right back into the pipes that carry drinking water to homes, schools, and businesses. It is a big step for California.
California’s new rules would let—but not require—water agencies to take wastewater, treat it, and then put it right back into the drinking water system. That means proving to people that recycled water is not only safe to drink but also not dirty. California would be just the second US state to permit this, following Colorado. It has taken officials more than 10 years to develop these rules, a process that included several studies by independent groups of scientists.
A project in San Diego is aiming to produce nearly half of the city’s water through recycling wastewater by 2035. And the Metropolitan Water District of Southern California aims to produce up to nearly 570 million liters(升)a day for its 19 million people. Adel Hagekhalil is with Metropolitan Water. He said the new rules will permit new projects that have not yet been considered.
California’s new rules require the wastewater be treated for all bacteria and viruses, even if they are not present in the wastewater. In fact, the treatment is so intense that it removes all of the minerals that make fresh drinking water taste good. That means the minerals need to be added back at the end of the process. Polhemus is a director of the drinking water group for the California Water Resources Control Board. “It’s at the same drinking water quality, and probably better in many instances,” he said, adding that it takes time and money to build these treatment centers. So, they will only be available for bigger cities at first.

8 . Bringing species like beavers (河狸) back to England is no longer a priority, the government said on Friday to criticism from wildlife groups.
A recent report shows that one in six UK species are at risk of extinction. In September more than 60 conservation organisations reported a significant decline in species due to expansions in farming and the effects of climate change. In recent years, animals and plants have been reintroduced by charities as part of efforts to restore the country’s reduced biodiversity.
Despite the government allowing this, the Environment, Food and Rural Affairs Committee concluded in July that there was an absence of long-term plans on how to manage this. In response, the government has now said that the “reintroduction of species is not a priority”.
The government said it was focused on increasing biodiversity through habitat restoration. The government’s environment department has come under scrutiny (详细审查) for not doing more to prevent sewage dumping and other forms of pollution in England’s waterways.
Sir Robert Goodwill, chair of the Committee, said he was disappointed with the government response. Bringing back extinct species is a controversial issue — although farmers and landowners appear broadly supportive, there are risks of reintroducing new species, and without clear guidance, problems could arise.
A recent study showed that river barriers similar to those built by beavers can protect communities at risk of flooding. But there have also been cases documented in Europe where beavers have built their dams in places that have damaged crops and changed rivers.
Joan Edwards, director of Policy & Public Affairs at The Wildlife Trusts said, “Reintroducing wildlife must be part of the UK government’s arsenal (武器) for tackling nature loss and climate change — it is astonishing there is no strategy for doing so.”
“The return of wild beavers can help to recreate lost wetlands, with a knock-on effect that benefits other wildlife including insects, invertebrates and birds. Beavers also slow the flow of water, which can reduce flood risks to towns and villages,” she said.

9 . It could be said that trees naturally call for attention as they climb toward the sky with their arms outstretched (伸展的). Yet, it’s still easy for us to ignore them. As we live busy lives, trees seem to play the role of a background.
Nothing could be further from the truth. Trees are important to the quality and health of our lives, our homes and our planet. Rooted to a single spot, they appear still. But that stillness is not equal to laziness. In fact, they are workhorses of the environment as the impact of their hard work carries miles farther than the ground in which they stand.
Globally, trees are the most cost-effective tool in the fight against climate change. Trees clean the air and absorb carbon. They promote biodiversity and support important habitats. For example, ring-tailed lemurs (环尾狐猴) are considered one of the most endangered creatures on the planet. A big reason is that half of the forests they depend on in Madagascar off the east coast of Africa were cut down.
Lemurs aren’t alone when it comes to a dependency on trees. Trees are home to 80% of all animals, plants and insects that live on land. Though humans aren’t always dependent on treetops for shelter, trees can save our lives, too.
Reports indicate in 2022 alone, heat waves across Europe caused an estimated 20,000deaths. Scientists point to trees as a way to fight against these urban heat islands, saying that increasing Europe’s tree canopy (树冠) by 30% could prevent thousands of deaths. Being around trees can also improve a person’s blood pressure, mental health and boost creativity. In fact, doctors in Canada are so convinced of nature’s benefits for the mind and body that they started suggesting patients free passes to national parks.
It’s time to put trees in the spotlight and inspire people to plant trees. This isn’t a one-sided relationship. What we give to nature we will receive in return.

10 . The specific cultural values of a country may determine whether concern about environmental issues actually leads individuals to engage in environmentally friendly behaviors, according to research published in Psychological Science.
Kimin Eom, a psychological scientist of the University of California, Santa Barbara, was inspired to investigate the links between culture, environmental concern, and environmental action after noticing that both public discussion and academic research on environmental behavior typically focus on people from Western countries. It is worth noticing because Western countries tend to have cultural values that prioritize individuals’ own attitudes and beliefs and encourage expression of them.
“The theory seemed to be that once individuals are led to believe in the urgency of environmental issues and have stronger concerns about sustainability (持续性), they will change and act to address the issues,” explains Eom. But this relationship might not hold for individuals living in more collectivistic (集体主义的) societies, which place more emphasis on social harmony and uniformity than on self-expression, Eom and his team assumed.
To examine what drives environmental action in individualistic and collectivistic cultures, the researchers conducted a study with participants from the United States (an individualistic culture) and Japan (a collectivistic culture). They found environmental concern was closely connected with environmental behavior — in this case, choosing environmentally friendly products — but only among American participants. On the other hand, believing that a large percentage of people engage in environmentally friendly behaviors was associated with making eco-friendly choices among Japanese participants, but not American participants.
The findings suggest that personal concerns are more likely to motivate people to take environmental action if they live in individualistic countries, while social norms (准则) are more likely to drive people to engage in environmentally friendly behavior if they live in collectivistic countries.
“Getting citizens actively engaged is critical to addressing urgent social challenges, such as climate change,” says Eom. “Our research suggests that scientists, policymakers, and activists need to understand how culture shapes the psychological factors of action to develop policies, campaigns, and interventions (干预) that address important social issues.”
