3 . A digital footprint is a record of a person’s online activity, and it’s becoming more common for companies to perform social media checks before hiring people, Business News Daily reported.

When posting on social media platforms, some students don’t think enough about how it could affect them in the future. Sometimes students post reckless (鲁莽的) content to their social media profiles without considering the potential consequences: They could be creating a damaging digital footprint that may prevent them from getting hired.

Before determining who to hire, 70 percent of companies screen potential applicants and look at their social media, with 18 percent of employees losing their job due to their social media posts, according to a September 2022 study by CareerBuilder, a company that helps employers hire in the United States. “Sometimes some people’s social media tell a lot more about somebody than an interview,” said Rithika Mothukuri, a senior media studies and production major.

A 17-year-old lost out on a job opportunity after the company performed a background check and saw her videos on TikTok, Buzzfeed reported. Many of the videos shared overly personal stories, which was enough to cost her a job.

Therefore, students should ensure a search for their name doesn’t surface inappropriate content because even one unprofessional post could potentially ruin job opportunities. They should perform a digital declutter if there is such content though it may be very challenging to do that. So the most important is to refrain (避免) from posting content that contributes to a negative image in the first place.

“I never had anything controversial or something that could get me fired from a workplace or school or something, but there are many cases of that happening and we should be learning from their mistakes,” said Kieran Mc Carney, a junior social work major.

While having a clean digital is important, it’s also important that students avoid doing anything that can be considered inappropriate in their real life. In this way, even others cannot post inappropriate images or videos of them on social media.

Whether it is watching television or using computers, teens experience serious physical and mental health     1     (consequence) after just two hours of screen use, according to University of Queensland-led research.

UQ researcher Asad Khan said the     2     (globe) study of more than 400, 000 teens is the first     3     (provide) evidence that teens are more likely to report physical and psychological complaints, if they exceed (超过) two hours of screen time.

“Psychological complaints from teens included feeling low, nervousness and sleeping difficulty, and physical complaints included headaches, backaches and     4     on, ” Khan said.

Key study findings showed teen boys who watched more than two hours of television per day, compared with those     5     watch less than two hours per day,     6     (be) 67 percent more likely to report high physical and psychological complaints while girls were at     7     (slight) higher risk at 71 percent.

High computer use for entertainment purposes was also reported to result       8     high physical and psychological complaints, with 84 percent higher risk in boys and 108 percent in girls.

“Our findings support existing public health recommendations of     9     (limit) screen use to a maximum of two hours per day for teens’ health,” Khan said.

The research     10     (conduct) in collaboration (合作) with Queen’s University of Ottawa, Canada.

Urban populations are projected to increase by 2. 5 billion by 2050.     2     But despite the rise in city-based farms, there’s still a lot we don’t know about them, including the economic and environmental costs.

Florian Payen, an environmental scientist, and his colleagues looked at previous studies done in 53 countries where crops were grown in different urban environments, including “grey” spaces such as rooftops, and by using different growing methods. They found that yields(产量) of urban crops were often the same as those from conventional farms. Just as importantly, they revealed the most commonly-grown types of crops and the most effective growing methods.     3    

It’s known that the benefit of urban farming is a reduction in food miles.     4     In one study, researchers analyzed the carbon footprint of different vegetables grown in greenhouses in Canada and that of the importing vegetables from the USA. “They found that it was less carbon-intensive to import the crops because of the high energy input required to grow them locally in greenhouses,” says Payen.

    5    Urban agriculture has the potential to enhance local ecosystems, attracting pollinators (传粉媒介) such as bees and birds that boost urban biodiversity while providing more green spaces to help keep cities cool and counter the urban heat island effect.

9 . We talk to the Perfect Planet experts about their experiences, hopes and advice.

We caught up with Dr Asha de Vos (Marine Biologist) and Dr Niall McCann (Biologist), who provided their expertise to the A Perfect Planet series. They have both witnessed, first-hand, the myriad (无数的) ways that humans have upset the delicate balance of our planet’s ecosystems.

Asha is a world-renowned marine (海洋的) biologist, TED Senior Fellow and ocean educator. She’s a pioneer in the research of blue whales and an expert on the current state of our oceans. Niall is a biologist, explorer and conservationist (环境保护主义者). He’s conducted remote-area biological research all over the world, and is a jungle expert, as well as a specialist in endangered species research. We discussed their hopes for the future, and what they want the audience to take away from the programme.

Seeing the damage caused by climate change can be a very bleak experience, but that hasn’t dampened Niall’s outlook. “I feel very positive about the future,” he explains, “because I spend so much time talking with young people — our future leaders — about nature, the environment, and humankind’s place in the world. The ‘Greta generation’ care deeply about the environment and are rightly holding those in power to account for their poor stewardship (管理) of the planet.”

Asha shares Niall’s view. When it comes to what practical steps viewers can take to tackle climate change, both experts have ideas.

“There are lots of little things we can all do to take care of our planet,” says Asha. “My favourite is a little unorthodox (非正统的). I ask people to share the stories of our planet, and specifically our ocean. Oftentimes, inaction or negative action comes from a place of ignorance, so empowering more people with the stories of our ocean and our incredible planet will help us to drive change. After all, if 70% of our planet is ocean, shouldn’t we have at least 50% of the world working for it?”

10 . When I made the decision to quit my full-time employment, I never thought that I could get involved in an increasing global trend. I had to leave my relatively high-profile position for an unexpected move that hurt my pride and prevented me from getting promoted. Yet, I excused my departure by saying “I wanted to spend more time with my family”.

Curiously, after around two and a half years, my experience in what Americans refer to as “downshifting” has turned my excuse into an absolute reality. I have been transformed from a passionate advocate of Linda Kelsey’s “have it all” concept, which she has been promoting for the past seven years in the pages of She magazine, into a woman who is content to accept a little bit of everything.

I have discovered that abandoning the idea of “juggling your life” and adopting the alternative strategy of “downshifting” has benefits that go far beyond financial success and social status. Nothing could convince me to go back to the lifestyle Kelsey used to promote and which I had previously enjoyed: 12-hour workdays, tight deadlines, the terrifying pressure of office politics, and the demand of being a parent on “quality time”.

After the widespread layoffs (裁员) brought on by cost-cutting in the late 1980s, America started to move toward a simpler, less materialistic way of life as a response to the economic downturn. In America, simplifying one’s life is frequently done for financial reasons, but in Britain, at least among the middle class I know, we have different motivations for doing so. For the women of my generation who were encouraged to keep juggling, downshifting is not so much a search for a mythical (虚无的) good life—growing your own organic vegetables, and risking turning into one—as a personal recognition of your limitations.
