1 . Neighborhoods filled with trees, grass and other flora not only improve the air and clear the mind--they can also reduce heart disease risk, recent studies suggest. Researchers say this may be more important in low-income areas, whether that’s an inner-city neighborhood or a suburb.
Green spaces often provide room for physical activity, an essential part for a heart-healthy lifestyle. But just living in a neighborhood thick with trees, bushes and other plants may reduce people’s risk of having a heart attack and other related diseases, according to a study published in the Journal of the American(JAHA). Those residents have lower stress levels and better cardiovascular(心血管的) health.
“There’s an economic difference when it comes to accessing green spaces, one that mirrors the differences found among people with cardiovascular disease,” said Rachel banner, director of park access. “Or, they may have a park nearby, but the park may be an unsafe place or there may be fences blocking(挡住) the entrances.”
Banner’s organization is part of the “10-Minute-Walk” campaign to ensure that there is a great park within a ten-minute walk of every person, in every neighborhood across the US.
Researchers continue to study the link between green spaces and heart health, and often the connection with an area’s economic level. A study led by Scott Brown looked at poor neighborhoods in Florida’s Miami-Dade County. They found people who lived in the greenest parts of Miami-Dade County were 25% less likely than those living in the green neighborhoods to have had a heart attack over a two-year period. He also suggested poor neighborhoods might gain the biggest cardiovascular health benefits from green spaces.
Brown points out that while evidence shows cardiovascular benefits from green neighborhoods seem to be especially greater for low –income residents, the common thread here is that for everyone , green space are associated with better health results.

4 . There have been many earthquakes around the world in recent years, so it is necessary to know some safety tips for earthquakes.
To begin with, remember the Drop, Cover and Hold method (DCH) from the American Red Cross. Drop down to the floor. Take cover under a piece of furniture (家具) and protect your head and neck with your arms. Hold on to the furniture until the ground stops shaking.
Besides, you should learn some tips about how to keep yourself safe in different places when an earthquake happens. If you happen to be having a class at school, standing beside a wall will protect you from falling things. Don’t stand near windows or under lights. When you are in a public area, like in a bookstore, get down beside the stands or go to the corner. Protect your head with your arms or bag. Stay away from big advertising (广告) boards. If you’re in the kitchen at home, move away from the fridge and lights.
What’s more, knowing about the magnitude of an earthquake is also necessary for you to take proper action when an earthquake strikes. The magnitude is from 1 to 10 and the higher the number, the bigger the earthquake. Usually, people can feel an earthquake of magnitude 3 to 4. When an earthquake reaches 5, farm animals feel nervous and the surface of walls cracks. When it reaches 6, houses may fall down and people are likely to get injured.

6 . As one of the biggest topics of the last decade, sustainability has become the beacon (灯塔) of hope to protect the planet. From supermarkets taking action on plastic packaging to the zero waste movement that can be practised from your kitchen, changes made by individuals and organizations across the globe have had an impact on the way we think, shop and live.
So what does that mean for the world of technology? You’d be forgiven for thinking that the words “sustainable” and “technology” don’t usually go hand in hand. E-waste is, after all, one of the planet’s biggest contributing waste streams. Not only that, but the materials that go into technology products are also part of the problem.
But with a challenge comes an opportunity, and there’s already some brilliant progress happening — great news for those of us wanting to be more sustainable with our technology. Firstly renewed products are having its moment. While consumers would previously turn their noses up at the idea of a second-hand device, there’s been a huge surge in demand for renewed technology products. The second major step in tackling the problem of e-waste is a change in attitudes from owning a product to subscribing for one. A subscription for a smartphone might sound like a foreign concept, but it’s already gaining momentum. At the forefront of this movement is a London-based technology startup, which offers a subscription service for the latest smartphones. As customers aren’t paying to own the phone at the end of their contract, the monthly price is significantly lower than average.
Studies show that extending a phone’s lifespan from one to four years can decrease its environmental impact by about 40%. So the next time it comes to refreshing your device — whether a smartphone, a laptop, a tablet or something else — consider the more environmentally friendly options that are at your fingertips.

8 . A selection of wildlife sculptures made out of recycled rubbish is being displayed at an exhibition at the Harley Gallery in Glasgow, England. The sculptures have, been created by Glasgow — based artist Michelle Reader, who has been working with recycled materials for over 20 years. The inspiration behind this collection of artwork was the increase in fly-tipping during the Covid-19 pandemic in 2020 and 2021. Fly-tipping is when people illegally dump rubbish or litter in a public place.
Reader told the BBC, “Glasgow Wildlife Trust showed me some of the materials that were found on their reserves — a washing machine, rusty bike frame, car tyres.” She decided to create wildlife sculptures out of these materials to encourage people to think about the damage fly-tipping can do to the environment and wildlife. Her three-dimensional artworks included recycled items such as skis, a gas mask, and washing machine, parts.
Reader often drew inspiration from the “beauty of the natural world,” and said that the large model of the white-tailed bee was inspired by the many hours she spent on her distribution during the pandemic. Another sculpture, of a bearded eagle, was inspired by the sighting of one such bird in the Peak District in July 2020. This was only the second time it had been spotted in the UK.
Other projects Reader has been involved with have highlighted issues such as the importance of recycling and reducing food waste. In April, the National Space Centre in Leicester, England, launched their Home Planet gallery, which featured an art installation from Reader. Using rubbish found in rivers, such as plastic bottles, tennis balls, footwear, and toys, Reader created a large wave sculpture to highlight the problem of littering.
Reader says that through her sculptures she draws attention to environmental issues in an attractive and humorous way. The exhibition is on at Harley Callery in Glasgow, England, until 24 July.

Take a good look at the American burying beetle. Once found in 35 states, the insect is assessed by the International Union for Conservation of. Nature as critically endangered. Like the tiger, the American burying beetle has orange and black stripes, like the tiger, the beetle is declining in number. The, tiger is an instantly recognizable symbol of species preservation, but most people aren’t familiar with the beetle.
This difference is an example of the domination of the so-called celebrity species — the fascinating creatures that nonprofits and government agencies use to raise public interest in conservation. Most nonprofit funds for animal protection go to species such as apes, elephants, big cats, rhinoceroses, and giant pandas. Tigers are often rated the most popular animal — and India, ho me to the majority of these big cats, spent more than $49 million on tiger conservation alone in 2019. Meanwhile, many lesser-known species of fish, reptiles, amphibians, and birds weaken in namelessness. Worldwide, more than 35,500 plant and animal species are on the edge of disappearing forever.
This leaves us with a tough situation. Conservation is underfunded, so how do we decide which species to save?
One potential solution, the debatable idea of conservation triage, holds that experts need to quickly decide which species can be saved while realizing that others can’t be saved. Conservationists have developed analytical tools to approach the question in a less emotional, but more practical way. Fish and Wildlife Service now uses this knapsack method — inspired by a hiker’s need to fit the most valuable items into a small space — to get the “most bang for their buck” in saving species. The method calculates the most efficient conservation strategies using factors such as costs to recover a species and its likelihood of going extinct.
