1 . Ten years ago, environmental journalist Ben Goldfarb was on a reporting trip about wildlife conservation. When he was shown around some new animal crossing structures near, Missoula, these new bridges and tunnels intrigued him. He was attracted by these beautiful human-built structures and inspired to write a book. Crossings: How Road Ecology Is Shaping the Future of Our Planet has now been published.

Through expert interviews, in-depth research and convincing analysis, Goldfarh brings to life the deadly consequences our 40 million miles of roadways have had and are having on the natural world and the creatures that inhabit it. A million animals are killed by cars each day in the US alone. Road salt pollutes lakes and rivers. And there's the barrier effect-the steady stream of traffic that prevents animals from migrating (迁徙) all together and finding habitats. Goldfarb writes that noise pollution is the most worrisome among all the road's ecological disasters. Both the engine noise and the tire noise greatly impact ecological environment.

Figures on deaths and disruptions (扰乱) are disheartening, but Goldfarb vividly describes how scientists are actively working on meaningful improvements to help animals and roads better coexist, such as wildlife crossings, from passages in Canada's Banff National Park to the famous Liberty Canyon Overpass in Los, Angeles. Another example is that in India, they built a new highway through a tiger reserve so that animals can come and go underneath the lifted freeway. Of course, that made the project more expensive, but it's ecologically the right thing to do.

Crossings is a truly important and landmark book on a subject whose full impacts continue to be disregarded or underestimated in considering conservation efforts. The book is a sympathetic, heart-warming guide to exploring the issues of wildlife survival and our own.

3 . After most people complete their undergraduate degree, they either take a break or jump into a job. Few, like Brianna Craft, set out to save the world.

It started when she was a freshman sitting in an environmental studies class in 2006. Craft was shocked when the professor described the harm climate change was having on people. She records the moment in her new book, Everything That Rises: A Climate Change Memoir.

After graduation, Craft spent a year in AmeriCorps, focusing on protecting the environment. AmeriCorps is an organization connecting individuals and organizations to help communities tackle their toughest challenges. “That helped me figure out that my future was not in doing science,” she says. Instead, she wanted to work with people and policy.

She then had an opportunity to attend the UN climate negotiations (磋商). That, in turn, prepared her for her current role as a senior researcher at the London-based International Institute for Environment and Development (IIED). Her focus is to ensure that the lowest contributors to greenhouse gases and those most affected by climate change have a voice in international climate negotiations.

For five years, Craft attended and supported climate conferences around the world, leading to the signing of the Paris Agreement in 2015. Craft says, “I wanted people to care about the work I did in the climate negotiations, and why we pushed so hard to form this agreement.” That led her to write Everything That Rises: A Climate Change Memoir.

Craft brings the viewpoint of an African American woman from a rural northwest community. She weaves (编织) together several storylines-including her difficult childhood with an irresponsible parent, her self-discovery in college and her work to help work towards climate agreements and ensure that even the smallest countries have a voice.

Milwaukee, Wisconsin, is road testing a new way to keep winter roads ice-free by spreading on them cheese brine, the salty liquid     1    (use) to make soft cheeses, like mozzarella(马苏里拉奶酪).

Wisconsin, also called “America’s Dairyland”, is famous for its cheese. The state produced 2.8 billion pounds of cheese last year! As a result, there     2    (be) a lot of leftover cheese brine.     3    (dispose) of the brine can be expensive. So what should cheese makers do     4     the waste?

Cheese brine has salt in it,     5    , like the rock salt, helps lower water’s freezing point.

    6    (normal), towns use rock salt to de-ice streets. The salt lowers water’s freezing point, causing ice     7    (melt). But using cheese brine could help both cheese     8    (produce) and cities save money, while keeping roads safe.

In addition to saving money, cheese brine could also be a more eco-friendly option. Many people suspect that all the rock salt used every winter     9    (harm) the environment, because road crews spread about 20 million tons of salt on U. S roads every year!     10    , by spreading cheese brine on streets before adding a layer of rock salt, Milwaukee may be able to cut its rock salt use by 30 percent.

6 . During the 20th century, an estimated 3 million great whales were hunted to provide humans with oil, meat and rose fertiliser. Roger Payne, a biologist and environmentalist, spurred (推动) a worldwide environmental conservation movement with his discovery that whales could sing.

This discovery was made in 1967 during his research trip to Bermuda (百慕大) when a navy engineer provided him with a recording of curious underwater sounds documented. Payne identified the tones as songs whales sing to one another and he was conscious from the start that whale song was to get the public interested in protecting an animal previously considered little more than a resource, curiosity or nuisance.

Payne saw the discovery of whale song as a chance to spur interest in saving the giant animals, who were disappearing from the planet. In 1970, Payne released the album Songs of the Humpback Whale. The record, a surprise hit, fueled a global movement to end the practice of commercial whale hunting and save the whales from extinction. It remains the bestselling environmental album in history.

The impact of the whale song discovery on the early environmental movement was immense. Many antiwar protesters of the day took on saving animals and the environment as a new cause. The humpback whale became the icon of a new environmental awareness. And the whales entered pop culture, no longer the fearsome beasts. In 1977, the whale calls were loaded on to the Voyager probes and sent into outer space.

Payne, graduating from Harvard University and Cornell University with a doctor’s degree, authored or co authored dozens of scientific papers, gave hundreds of lectures, made countless television programmes and films, and led 100 oceanic expeditions. Payne had started an ambitious new project: CETI, a combination of scientists using new technology to interpret what whales might be “saying”.

8 . XI’AN — China has introduced various emergency responses and long-term measures against air pollution in the central and eastern regions.

The air quality index (AQI)) for Xi’an reached 500 on Wednesday afternoon, at the top of the AQI scale, according to the national air quality monitoring website. Xi’an weather forecasters predict the smog will continue for the next week and air pollution may worsen.

“I have to keep buying masks for my family,” said Liu, buying masks at a pharmacy (药店) near her home in downtown Xi’an. “This is the only thing we can do to protect ourselves.”

On Wednesday, a city government emergency response plan was put into action, suspending all construction and taking at least 50 percent or government vehicles off the road. Power plants must limit their output and reduce emissions.

Nearly half the country, more than 100 cities in 20 provinces, has suffered from smog since last December. Many have taken action, including experimenting with artificial methods to reduce smog, limiting vehicle use and fining polluters.

Assessments based on GDP alone were abandoned last month and more emphasis has been put on public well-being and the environment. Whether the move will be effective or not in forcing the local governments to consider environmental issues over economic growth remains to be seen. Environmental protection professionals are doubtful about the immediacy of the effects of these measures.

Xiao Hang, an urban researcher at the Chinese Academy of Sciences, said it took London 50 years to lose the moniker (绰号) “foggy London town”, and Los Angeles still struggles to control its photochemical (光化学) smog. “We can’t ignore environmental problems during the development process and China has a long way to go,” he said.

The story started with the killing of a 19-year-old female elephant at the hands of hunters in northern Kenya in 2016. Her two calves (幼崽) then started a journey to the area where their mother     1    (kill). They were too young to deal with the hidden danger in the wild     2     the protection of adults.

According to that sad but inspiring true story, elephant-lover Sun Xiao wrote a children’s book Samburu, I’m Back. Sun is     3     witness to the story told in his book. He was, at the time, in Kenya working for Save the Elephants, a UK charity     4     (base) in Nairobi, capital of Kenya. When he and his peers found the two calves wandering in the wild, they tried to change their course.     5     (lucky), through great efforts they managed to transport them to an elephant reserve.

In the past decade, Sun     6     (devote) himself to spreading knowledge of elephants via a     7     (various) of methods, such as writing children’s storybooks     8     (feature) the elephants, sharing photos he took of elephants       9     posting hundreds of articles he wrote on social networks. He intended to raise public awareness of the urgent need to protect the creatures from hunters,     10     kill them for their ivory tusks.

10 . Zo Trisha Prinsloo cares about the beaches of Cape Town, South Africa. She leads cleanups there. She set up a group called Save a Fishie years ago! It has picked up plastic bottles, food containers, and other waste. “My main goal is to constantly remove anything and everything I can off our beaches,” she says, “and to try to prevent litter from being taken out to sea.”

Lately, however, Prinsloo has noticed an increase in a certain kind of plastic waste. It’s from PPE (personal protective equipment). Her group Save a Fishie saw eight different kinds of gloves” during a cleanup. I find masks more and more regularly, too,” she said.

People everywhere are wearing PPE to protect themselves from COVID-19. But when PPE isn’t thrown out the right way, it pollutes the environment and endangers wildlife. Each year, at least 8 million tons of plastic enter the world’s oceans. Now this waste includes more PPE. Last year, the Ocean Conservancy led by its chief scientist George Leonard held its annual International Coastal Cleanup. “We’ve found tens of thousands of PPE waste, and more of it is being put into oceans. PPE waste is a significant threat to oceans,” Leonard said. PPE waste can hurt ocean animals that can eat it or get tangled (缠绕) in it. Sue Schwar manages South Essex Wildlife Hospital in the UK. Her team saved a seagull. Its legs got tangled,” she said. Thankfully, the staff was able to untangle the bird and set it free.

PPE will continue to be common until COVID-19 ends, but there’re steps you can take to reduce its environmental impact. Wear clean reusable masks and deal with them carefully before throwing them into rubbish bins to make sure animals won’t get tangled up. Put used PPE in a bin with a safe lid (盖子). This is important when the bin is outside because masks and gloves can be carried away by the wind.
