2 . With needle-like teeth and sharp pointed nose, a gray nurse shark isn’t a creature that most people would want to meet. But Shalise Leesfield isn’t one of them.
The Australian teenager couldn’t think of a better creature to meet when scuba diving off the coast of South West Rocks, near her home in Port Macquarie, a coastal town north of Sydney.
“Many people say gray nurse sharks look frightening, but I think they are the sweetest animals ever,” she says.
The slow-moving sharks, which like to stay near the sea floor in warm, shallow waters, are — for the most part — harmless to humans. But the gray nurse shark is under threat. Populations have fallen and habitats have been lost due to ocean warming and human development, according to the International Union for Conservation of Nature (IUCN), which lists the species as seriously endangered.
One area where they can still be seen is Fish Rock, an underwater cavern (洞穴) with a unique ecosystem, 40 miles up the coast from Leesfield’s home. But fishers are allowed access within 200 meters of Fish Rock. This is leading to a drop in the number of gray nurse sharks and increased pollution, says Leesfield. She wants to enlarge the no-fishing area, establishing a protected zone.
With Leesfield’s efforts, the area has been nominated as a Hope Spot, which is part of the mission Blue program launched by famous oceanographer Sylvia Earle that identifies places as critically important to the ocean’s health and supports protection.
“When people think about Hope Spots, they think about Sydney Harbour or the Great Barrier Reef. So to get Fish Rock up on that list is just such incredible news,” she says.
Now, Leesfield is working with politician Cate Faehrmann, marine spokesperson for the Australian Greens party in New South Wales, to legalize protection of the sharks and make the no-fishing zone protected by the law.

3 . Laura Madden is a small business owner and sustainable fashion advocate. “ReFashioned Art is a purpose-driven business, combining style and sustainability (可持续性),” Madden says,“I love fashion, but I also care deeply about the environment.”
She slowly built her network and became an influencer who ran a popular blog. She shares that her passion for sustainability came about in 2015 when she watched a life-changing documentary about the social and environmental issues brought up by the fashion industry. “My guilty pleasures- shopping and fashion - that I assumed weren’t hurting anyone, were in reality hurting a lot of people,” she says.“I couldn’t stand the fact that something I loved so much was creating so much suffering on the planet. How could something that brought me so much beauty and joy be so dirty and destructive?”
With this realization, Madden became an advocate for sustainable fashion-including purchasing most of her own clothes second-hand and supporting sustainable brands. Although she was busy enough in 2019, she became a professional artist, creating pieces made from sustainable materials.
She notes that ReFashioned Art is first and foremost an art brand. “I am using my work to tell a story and create a narrative that style and sustainability can co-exist,” she says. “By repurposing old items into something more fashionable, elegant, and contemporary, I hope to inspire you to look for beauty where it is not normally found.”
For those interested in supporting sustainable art and fashion. Madden shares,“Get creative and look for beauty. Looking forward, I would love to partner with more designers.”
She adds,“We only have finite resources. The best thing we can all do is ask, ‘How else can I use this item?’”

5 . Last fall, the Great Salt Lake hit its lowest level since record keeping began. The lake sank to nearly six meters below the long-term average. The lake’s shrinking threatens to upend the ecosystem, disturbing the migration and survival of 10 million birds, including ducks and geese.
Duck hunters aren’t the only ones worried about the Great Salt Lake. The decades-long decline in lake level is raising alarm bells for millions of people who live in the region. The low lake level and increasing salts in the lake water threaten to destroy economic mainstays like agriculture, tourism and mining. Exposed salts can also reduce air quality and so threaten public health.
Saline lakes (咸水湖) are terminal lakes. They have no rivers flowing out of them. As water disappears, salts are left behind. At the same time, the people who live in these deserts use freshwater for crops, homes and industry. Residents get water from streams and rivers into canals, pipelines or reservoirs before it reaches the lakes. And as the lakes shrink, the salt in water increases.
Lake Poopo, a highland lake in Bolivia that used to stretch 90 kilometers long and 32 kilometers wide, is now a salty mud flat. The Aral Sea shared by Kazakhstan and Uzbekistan, once the world’s fourth largest lake, has at times in recent decades shrunk to a tenth of its historic 68,000-square-kilometer surface area. Some saline lakes, like Nevada’s Winnemucca Lake, dried up so long ago — the waters that fed it were led to agricultural fields — that most people have forgotten they were ever wet.
The good news is that people still have time to halt the Great Salt Lake’s decline by using less water. Cutting agricultural and other outdoor water use by a third to half through a combination of voluntary conservation measures and policy changes would allow the lake to refill enough to support the region’s economy, ecology and quality of life. If this succeeds, the Great Salt Lake can be a model for how to save other saline lakes around the world.

9 . E-waste is a serious problem that isn’t going to get better on its own.
Maybe the biggest cause of our e-waste problem is the fact that we buy things that we just don’t need. Next time you feel like you need a device or electronic item, stop yourself and ask if it is truly necessary. This is maybe also the easiest way we can manage e-waste.
If you do not need a piece of equipment and it is in good enough condition to be reused, donate it as soon as you can so that somebody else can use it. Donations are good for us because they are a useful way to get tax deductions (减税), and a lot of times that tax deduction will be close to the value of the item had you tried to sell it.
There are also places to sell electronics that might be valuable to somebody else. Just be sure to sell them right away, because they lose value very rapidly in our changing market.
If you are frequently receiving memory sticks and little gadgets, collect them into a good-e-bag.
A.Organize your electronics. |
B.Don’t buy too many gadgets. |
C.Take your electronics back to the store. |
D.Here are some do-it-yourself tips on how to manage e-waste. |
E.Donation means a lot for people who are in need of electronic devices. |
F.Your house will be cleaner, you will save money and you’ll be doing a good thing. |
G.Whenever you no longer need a USB stick or a small electronic device, toss it into the bag. |
10 . After being driven to near extinction, wolves are back in Washington state.
Wolf 32M, called The Old Guy by wolf specialist Ben Maletzke, lived some 12 years as the patriarch (族长) of the Teanaway Pack, kicking off the recovery of wolves in Washington. The pack’s territory was roasted by wildfire in 2014. But wolf 32M and his family remained in existence, bringing the call of the wild back for the first time in a century. These wolves are what Maletzke calls stepping stones in recovery — the animals that could help lead the way to new territory not yet repopulated by wolves.
Wolves spread to new territory to find mates and begin packs of their own. It is this pack dynamic that wildlife biologists are counting on, in time, to urge wolves into areas where they do not presently live. “We just need a couple to pick up and go,” Maletzke says.
All along, the Teanaway pack has stayed mostly out of trouble probably, helped by a lot of range riding (牧区巡逻) intended to help reduce conflicts over wolf recovery by keeping wolves away from cattle. “He is an example of wolves living and doing what they do, even around people,” Maletzke says of wolf 32M.
Story Warren, a student at the University of Montana, was just a girl when she first saw 32M’s tracks in the Teanaway River Valley — an exciting encounter that helped generate a serious interest in wildlife that now fuels her studies. To her, the return of the wolf is about more than the species; it is about recovering something even bigger: hope.
“Growing up in my generation, there is so much bad ecological news, a lot of hopelessness about climate change and loss of biodiversity and extinctions,” Warren says, “To have something as wild as wolves coming back to Washington is very encouraging for me — just to know such an amazing and powerful creature exists.”
