4 . Umbrella species are species that are selected for conservation-related decisions because the conservation and protection of these species indirectly affects the conservation and protection of other species within their ecosystem. Umbrella species help in the selection of potential reserve locations, as well as the determination of the composition of the reserve. Umbrella species usually have a large area requirement for which the conservation of the species extends the protection to other species sharing the same habitat. Umbrella species are representative of other species in their habitat since they are known species, and they also determine the area of conservation. The protection extended to the other species by the presence of the umbrella species is known as the umbrella effect.
The concept of umbrella species has been used in the creation of wildlife corridor with focal species chosen for their suitability in the conservation process. The umbrella effect is the degree of species impact on other surrounding species resulting from the conservation measures undertaken in the area. Umbrella species is a faster and less expensive means of conservation since it reduces the cost of investment in sampling that is necessary for prioritizing (优先考虑) an area for conservation.
Umbrella species can be both plants and animals species with either of the species offering protection to the other. Most of the umbrella species are listed as endangered or threatened on the IUCN (International Union for Conservation of Nature and Natural Resources) Red List, and therefore their conservation extends to the conservation of their habitat. Some of the notable umbrella species include spotted owl whose conservation protects the old growth trees the conservation of both species has led to the protection of mollusks and salamanders within the protective boundary. The protection of the Bay checkerspot butterfly automatically leads to the protection of the grassland while the conservation of the Amur tiger in the Russian Far East also means an automatic conservation and protection of the deer and boar in their habitat. The protection of canebrake offers further protection to broader species within its habitat because of the umbrella effect. Protection of the rattlesnakes also offer protection to other wildlife species found within their habitat.

5 . The most beloved bird in history may very well have been a 29-year-old pigeon by the name of Martha. It was the early 1900s, and Martha was at the height of her fame. Perched on her humble roost at the Cincinnati Zoo, she was an object of fascination to the thousands of visitors who lined up just to catch a glimpse. Martha may not have looked the part of an animal celebrity, but she was hardly average—in fact, she was the very definition of one of a kind. After the death of her companion George in 1910, Martha had become the world’s last-living passenger pigeon.
There was a time not long before when her kind accounted for more than a quarter of the birds in North America and may have been the most abundant bird species on the planet. Passenger pigeons used to travel at 60 miles an hour in flocks a mile wide and 300 miles long. Witnesses compared them to a train rumbling through a tunnel.
Ironically, the passenger pigeons’ very abundance may have spelled their doom. An agricultural pest and reliable source of protein, they became easy targets for hunters who killed them in the tens of thousands. In a matter of decades, a bird that once numbered in the billions was reduced to a few, and then, eventually, to one.
Martha, who’d grown up in captivity, had no offspring of her own. At 1 p.m. on September 1, 1914, Martha fell from her perch, never to rise again—one of the rare occasions in which historians could identify the exact moment of a species’ extinction.
Of course, the real tragedy was that the loss of the passenger pigeon was neither surprising nor unique. For as long as the Earth has sustained life, it has also seen the permanent disappearance of life forms, the dinosaurs being a particularly extreme example. But Martha’s high-profile death trained national attention on an alarming new trend. Close to a thousand animal species alone have died off in the last 500 years, and the trend is only getting worse.

8 . Confessions of an annoying Mosquito
If you’re reading my confessions (自白), congratulations! You’ll have a safe and healthy summer.
We love when you work up a sweat. It’s really the carbon dioxide you breathe out that makes us beeline to ward you, not the fragrance of your “sweet blood.”
Love beer? So do some of us. They can tell when you’ve been drinking because your skin chemistry changes, and it attracts them
Pregnant? Yum. If you’re having a baby, you emit more carbon dioxide and your belly has a higher temperature, drawing some of us right to you. Sorry, baby.
Hate getting bitten up? Blame the ladies. Males do not eat human blood: They get all their nutrition from plants. After we have a blood meal, we can lay anywhere from 100 to 400 eggs
Smelly feet are simply delicious. Scientists have shown we find your toes ten times more inviting than Limburger cheese.
If your home’s landscaping is well tended, we won’t like it as much. We like to hang out in thick, overgrown vegetation. The darker and more damp, the better. And puddles (水沟) of smelly water is where we like to lay our eggs.
Got those CO2-emitting traps in your yard? Great! You may think you’re outsmarting us with these devices, which emit carbon dioxide to lure (引诱) us into a trap. But they may attract more of us than they are able to trap, increasing our presence in your yard.
When it comes to West Nile, end-of-summer bites may do more harm. It’s simple logic: We bite birds with West Nile virus; then we bite humans and spread it. By summer’s end, we’ve had more chances to bite infected birds.

9 . It was October 2005, and the catastrophic earthquake killing some 79,000 people in Pakistan had reduced the valley to mud and ruins.
Yasmeen Lari, a 65-year-old architect, was there to help lead the reconstruction of settlements, but she had never done disaster work before. Lari was known for designing smooth towers of glass and concrete. But here, she’d be drawing plans for earthquake-resistant homes using stone and timber debris(木材碎片). With each passing day, she felt deeply right to do disaster-relief work. So she made it her new mission, spending the next four months working with volunteer architects and engineers from Pakistan and abroad.
Inspired by local buildings made with sustainable materials such as timber debris, bamboo and mud, Lari’s shelters can better withstand disasters. Lari says this local, cost-effective and zero-carbon approach is creating an ecosystem. Anyone can learn by watching DIY videos on Lari’s Zero Carbon Channel on YouTube.
The design won a UN World Habitat Prize in 2018.“We need to believe in people’s capacity to bring about change. I treat displaced people as partners, not victims. They know what to do,” says Lari.
Over the decades, Yasmeen Lari has won many awards as architect and environmentalist. While it may seem like an unlikely path for a girl who was born into a well-to-do family in1941, she had an unconventional upbringing. At home, her father would talk about the desperate need for housing. Listening to her father talk about the housing crisis and need for architects made an impression on Lari. On a family visit to London when she was 15, she applied to architecture school at Oxford Brookes University. She laughs as she recalls her bravery.
At age 83, Yasmeen Lari is still full of ideas about zero-carbon designs, skills building and self-sustaining villages. “Architects can no longer work for just the one percent,” she says. “That doesn’t allow them to serve humanity as much as they could.”

10 . Shanya Gill, a 12-year-old middle schooler from San Jose, California, won the top award in the Society for Science’s annual middle school competition for designing a fire detection system that is superior to existing ones, according to a press release from the organization.
Shanya’s inspiration came after a fire destroyed a restaurant in her neighborhood during the summer of 2022, reported Washington Post. “I had never really experienced something like that before,” she told Washington Post about the early morning fire at Holder’s Country Inn, which started in the kitchen. “They had smoke detectors, and yet it still burned down,” she added.
After she studied fire statistics and saw how common fires are, Shanya decided that she was going to do something about it. She spent more than a year developing a fire detection system that she believes could prevent the fire. That’s because smoke detectors sense active fires from the smoke in the air, while Shanya’s thermal imaging device is designed to stop fires from occurring.
Her complex system has two parts, a thermal camera and a Raspberry Pi, a tiny computer. The device detects when a heat source has been left unattended for ten minutes and sends a text message alert.
Creating the prototype (原型) was difficult and the hardest part was the coding. “I had two designs, and the final device succeeded because it outperforms smoke detectors in speed and accuracy.” Shanya wants to bring the costs down to $60 to make it even more affordable than hardwired smoke detectors.
“Shanya saw a problem and tried hard to solve it, and that’s what we need to encourage with all young people,” said Ajmera, president and CEO of Society for Science. Her remarkable research not only reflects her talent but also paves the way for an exciting new future.
