1 . The Art of Spreading New Plants from Cuttings

In the world of gardening, there’s a magical journey where you use the power of cuttings to create new life. Spreading plants from cuttings is a satisfying and sustainable (可持续的) practice. This increases your green treasures.    1    

Selecting and Preparing Cuttings

Not all plants respond equally to the spreading process.    2     Many plants are proper for spreading through cuttings. Research the specific needs of the plants you’re interested in, paying attention to factors like season, plant age, and overall health.

Choose healthy, disease-free stems (茎). Using clean, sharp knives, take your cuttings in the morning when the plant’s water levels are best. Once you have your cuttings, remove leaves from the lower part of the stem to reduce water loss.

Developing Your Cuttings to Plants

    3     Regularly water the cuttings to maintain wetness and monitor the soil condition. As roots develop and the plant establishes itself, gradually adapt it to the conditions of its future home. The journey from a simple cutting to a healthy plant may take weeks or even months, but the rewards are well worth the wait.

Sustainable Gardening Practice

Spreading plants through cuttings is not just about expanding your garden. It’s a sustainable practice.    4     Sharing your new plants with friends and fellow gardeners creates a sense of community and spreads the joy of growing your green family.

Creating new plants from cuttings is a fascinating journey that will change your garden into a pleasant plant-filled garden.     5     With a bit of patience, care, and a touch, you’ll find great joy in seeing the cycle of life happen in your very own garden. Happy spreading!

2 . People have long watched moths (飞蛾) and other flying insects flock to streetlamps, lights and flames. These insects appear attracted by the light. But a new study suggests they may just lose track of which way is up.

Previous theories say light probably blinds flying insects so that they get trapped by the light, or maybe they interpret light at night as a place to fly for a quick escape. Now the new study suggests flying insects instead turn their backs to the sky’s light to keep their feet pointing toward the ground. Insects naturally turn their backs toward light. But when that light is from an artificial source, it may affect their sense of direction, leading to them flying in circles or diving toward the ground.

At a field station in Costa Rica, Samuel Fabian, an entomologist from Imperial College London in England and his teammates set up hanging and standing lights, and then used high-speed cameras to track wild, flying insects including moths and flies. Some circled the lights endlessly, and others flew sharply upward, losing speed until they couldn’t fly any higher. When the light source pointed up, some insects turned around and headed for the ground. During the flight, the insects always kept the lights at their back even if they’d end up crashing. Crash landings were common when the team lit up a white sheet on the floor. But not when a white sheet — stretched into a height above the floor—was bathed in diffuse (漫射) light, much as the sky would be, insects flew through the area without getting trapped by the light.

The team also observed some species in a lab. Moths and dragonflies generally behaved like the wild insects, and they kept the light at their backs. However, in the lab, fruit flies, like oleander hawk moths — which can fly in the dark — could fly over LED lights without being thrown off course. In the wild, though, the moths still crashed. Maybe this is because, Fabian says, the insects can sometimes control their response to light, or over time, they might learn to avoid artificial light.

4 . “There’s a little black woman walking, spraying (喷洒) stuff on the sidewalks and trees on Elizabeth and Florence...” he told the police. Her neighbor saw her spraying something on the sidewalks and trees and this made him worried. In the call to 911, he described the child as “a little black woman”.

Well, the “little black woman” was actually 9-year-old Bobbi Wilson, a young scientist. The fourth-grader had created her own insecticide (杀虫剂) to fight spotted lanternflies (斑衣蜡蝉). She came across the recipe on TikTok and had recently learned that the harmful species damages trees because they feed on their sap (树液). Bobbi was simply testing out her invention in her neighborhood when the police call was made.

“That’s her thing,” her mother Monique Joseph said. “She’s going to kill the lanternflies, especially if they’re on a tree. That’s what she’s going to do.” Bobbi’s 13-year-old sister, Hayden Wilson, also defended her, noting that Bobbi “was not only doing something amazing for our environment, but she was also doing something that made her feel like a hero”. Luckily, what happened didn’t influence Bobbi’s spirit and has led to some positive experiences for her.

She has since been recognized by several organizations for her environmental efforts. She has also been invited on special tours. One took place at the Princeton Plasma Physics Laboratory. Another was given by the United States Department of Agriculture of New Jersey at a plant where they discussed lanternflies. But that’s not where her recognition ends! The Association of New Jersey Environmental Commissions (ANJEC) honored Bobbi with their Sustainability Award for her work to save trees and fight lanternflies.

“We were excited that she was doing that,” Ann Marchioni of the ANJEC said. Ann added that the organization praises volunteers for being “hands-on” in their community. In addition to the award, she and her family got to visit with a group of black female scientists at Yale University. They showed her various labs and even invited her to donate lanternfly specimens (标本) for the university’s work.

5 . “Leave no track” is popular among many campers who are concerned about our environment and favor sustainable (可持续的) travel. Its goal is simple; to minimize human-created impacts on the natural world.     1    

Reject plastic and paper. First and foremost, one of the easiest ways to reduce the impact of camping on the planet is to go plastic and paper-free. Instead of single-use plastics and paper plates, choose bamboo or other recyclable camping dinnerware and food packages.       2    

Rent or buy a used tent. Instead of brand-new equipment, consider renting camping equipment instead. Outdoor retail (零售) brands like REI offer a wide variety of camping products to rent, including tents.     3     For those keen on purchasing something new, try brands like Patagonia that put sustainability first to reduce waste and support eco-friendly practices.

    4     In addition to eco-friendly tents, it’s good to ensure that other camping essentials, from hiking shoes and sleeping bags to clothing and blankets, are also gentle on the environment. And remember, whatever is packed in should also be packed out.

Only camp in designated (指定的) camping areas.     5     However, developed campgrounds, which are specifically designated for camping, are usually available by reservation and don’t require campers to walk wearily into the wilderness to clear space to set up a tent. Designated camping spots usually have other advantages like bathrooms, showers, picnic tables, and more.

6 . A four-year-old dog named Kob became a hero in its neighborhood by discovering a possibly life-threatening gas leak (泄漏) in its owner’s front yard.

This dog’s actions not only_______its surroundings, but also stressed the importance of the behavior of our furry friends.

The story began when Kob,_______by 28-year-old Chanell Bell, started digging a large hole in the yard. At first, Bell thought this was typical dog_______, but as the hole grew larger, she became_______. Recognizing that Kob’s actions were unusual, she trusted the dog’s judgment, considering its normally well-behaved nature.

After_______a recent gas leak in her home, Chanel_______a gas detecting(探测) tool. She followed her sense and chose to use the tool to_______the newly dug hole by Kob.

Finding gas coming out of the hole, Bell_______contacted the authorities about the issue.

“If it wasn’t found, the_______would have continued to escape into our homes,” Bell said. “We were told it could have caused________health effects like breathing issues, brain damage, and even________. They told me that something as simple as________a light could have caused a burst!”

During the repairs, workers________three main gas leaks in Bell’s neighborhood caused by aging________. It took the workers over three days to repair the leaks and replace the old equipment.

Throughout the repairs, the workers________Kob for saving the neighborhood.

7 . A new study suggests that the climate change diet might not be good for polar bears. With Arctic (北极) sea ice reducing, many polar bears have to go to land for their diets during parts of the summer.

A study looking at Hudson Bay polar bears tried to figure out if the creatures can keep their healthy weight levels on such a diet. Researchers found that the majority of the creatures are losing weight no matter what they do to try to increase it.

Some bears find a lot of food — berries, eggs, sea birds and so on. But to get such foods takes a lot of effort. The bears use so many calories trying to eat that they end up losing weight and burning more energy than they take in. Other bears go into a time of semi-hibernation (半冬眠). But they also lose weight. So either way — eating different foods or sleeping a lot — does not work.

Researchers found that 19 of the 20 bears studied dropped an average of 21 kilograms over three weeks of being studied. The research observed their calorie intake, energy use and breathing in the wild. The bears lost about 7 percent of their body mass on average in just 21 days.

Polar bears try to keep up their weight in the summer after a spring when they eat a lot and gain weight. In the area of the Hudson Bay where researchers studied, lack of sea ice has meant polar bears are on land three weeks longer than in the 1980s.

Last September, when Arctic sea ice hit its yearly low, there was about 2.6 million square kilometers less sea ice than the same time in 1979. The United States Fish and Wildlife Service lists the polar bear as a threatened species due to the loss of its sea ice habitat.

Overall, the research shows that it is unlikely that polar bears can adapt to living on land.

9 . International ShakeOut Day This Year

This year’s International ShakeOut Day is October 17, when millions of people worldwide will take part in earthquake drills (演习) at work, school, or home! It is a great way for your family or organization to become better prepared to survive and recover quickly from big earthquakes.

At 10:17 am (local time) on 10/17, you can join millions of people across the world in practicing earthquake safety. While we encourage everyone to take part, you can sign up for your ShakeOut drill for any day of the year, and drill at a time of your choice. You can also include people in different locations through videos.

· Most participants (参与者) are in one of the official ShakeOut Regions listed below the page (with current sign-up totals). People and organizations in other countries can also sign up.

· All regions take part in it on October 17, 2024, unless specified.

ShakeOut began in California and has also been organized in many other states and countries. Official ShakeOut Regions require special local or regional cooperation, typically by an emergency (紧急情况) management agency or a union of many organizations. If you are interested in establishing ShakeOut for your region, please contact us at https://www.shakeout.org. If your state, province, or country is not yet taking part, you can sign up for yourself or your organization as part of the global participation total.

10 . Low-effort things you can do to live sustainably

You might think you need to change a lot of your daily habits to live sustainably but, in fact, becoming more eco-friendly is much easier than it might seem. Below are some easy steps towards becoming more sustainable.

Shop at farmer markets.

Getting your daily fruit and vegetables from a local farmer market is an easy way to reduce your carbon footprint while eating healthily. It cuts out lengthy stays of the products in refrigerated storage and up to thousands of miles of fossil-fueled transportation.     1    

Practice meatless Mondays.

Global meat production is a big contributor to greenhouse gasses.     2     It isn’t necessary either. Many people reducing their meat consumption by a small amount would still have a great impact. According to a study, you could reduce your carbon footprint by as much as 8 pounds each week just by practicing meatless Mondays only.

Dispose of unused medications properly.

Flushing (冲) unused medications down the drain (下水道) can pollute water supplies affecting everything downstream. You shouldn’t throw medications away either as they can be dangerous for others to find.     3     Leftover medications can be chemically dealt with and disposed of in a safe and secure way there.

    4    

It is easy to understand that buying something used is more environmentally friendly than buying something new and clothes are no exception.     5     According to the United Nations, the fashion industry is responsible for 2% - 8% of global carbon emissions (排放量). Buying something used keeps things out of landfills and reduces demand for new items.
