Seagrass meadows（海草床）are wonder plants growing beneath the a. They feed and shelter a life and are masterful at storing carbon. Thanks to the assistance of tiger sharks, a huge agrass meadow in the Bahamas Banks was recently discovered, offering the world a tool to fight climate change.
Seagrass has usually been detected by Earth-orbiting satellites that identify darker patches in the blue water. In this study, tiger sharks were lected as rearch tools due to their highly consistent associations with agrass ecosystems. They spend 70% of their time in agrass meadows. The team equipped eight tiger sharks with satellite tags, ven sharks with camera tags, and ud a 360-degree camera on a shark for the first time ever.
lovingThe data rearchers collected was astonishing. The world’s largest agrass ecosystem, measuring at least 66,900 square kilometers, has been discovered. This reflects a 41% increa from previous estimates of global agrass. Seagrass can capture（捕获）huge q
uantities of carbon by photosynthesis and stores it on the afloor. In terms of climate change, this is excellent news; agrass is 35 times faster at removing carbon than tropical rainforests. When referred to global agrass carbon stock estimates, the study indicates that agrass in the Bahamas may contain 19.2% to 26.3% of all the carbon stored in agrass meadows on Earth.
Yet agrass meadows are rapidly disappearing, with over 92% of meadows in the UK gone, according to the World Wildlife Fund. Scientists are collecting eds and trying to grow new agrass meadows through restoration projects. This new discovery offers optimism and proves the importance of the ocean for healing.
The sharks led us to the agrass ecosystem in the Bahamas, which we now know is likely the most significant blue carbon sink on the planet. What this discovery shows us is that ocean exploration and rearch are esntial for a healthy future. The untapped potential of the ocean is limitless. The meadows can be protected and can be replicated, offering hope for climate change around the globe.

The topic of China’s “slash youth” has fueled heated debate on social media recently, drawing attention to the diver pursuits of the younger generation.
The slash youth, which could also be called slashers or slash-generation — means tho who refu to be defined or bound by just one personal identity. They are keen to prent themlves as multiple and sometimes distinct identities, such as a nur and model, a teacher and stand-up comedian, and an engineer and band player. Rather than material comforts, they pursue meaningful achievement.
A diver career can enable them to develop new experiences and talents as well as social and professional networks, leading to greater flexibility in life and work, recognition and satisfaction.
A study on “slash youth” published in the China Youth Rearch magazine analyzes the background of this phenomenon: with part of modern society’s structured organization and stability norms（规范）are broken, flexible labor markets and structural unemployment has emerged, eliminating the n of job curity of the young people in
qremployment. Young people also face the dilemma of lf-actualization（自我实现）, including the n of powerlessness, lost n of value and lack of lf-identity in the profession, which forces them to re-find the meaning of work.
“The ‘slash life’ shows that our society is becoming more and more diversified and inclusive, and it welcomes everyone’s lf-fulfillment,” said Shi Yanrong, an associate rearcher from Tianjin Academy of Social Sciences. “Young people no longer have to rely on work and money for their n of lf-worth. They tend to create their own identities.” The rearcher added that against the background that people have multiple interests and are willing to pay for the interests nowadays, the “slash life” of the youth would drive the growth of a new economy, just as animation（动漫）culture affected the market.
