新聞及香港科大故事

佘焯成是2011年的數學理學士畢業生，一路走著順遂且豐富多彩的人生旅程。畢業短短數年，他用兩年時間苦心經營的數學補習社，已讓他嚐得創業成功的滋味。  身為數學科補習名師，數學讓佘焯成名利雙收，但沉重的工作壓力亦令其健康在2017年響起警號，意外地改寫了他的人生。  他憶述：「我當時受腸胃問題困擾，朋友建議我服用天然原蜜調理身體，效果很好，立時引起我對蜜糖和蜜蜂的興趣，自此不停研究，我的人生亦因此改變。」 焯成向元朗一位本地蜂農拜師，學習怎樣在不用抗生素、不加糖、不熱壓的情況下生產蜂蜜，愈是鑽研，興趣愈濃，2017年更與兩位科大校友合作創辦自己的第二盤生意「香港原蜜」。自此，他不僅積極宣揚原蜜對健康的好處，更致力保育蜜蜂，以協助全球生態系統保持平衡。  近十年來的絶大部份時間，很多蜂農都表示每年失去三成或以上的蜂巢。全球蜜蜂數量銳減，嚴重威脅各式各樣人類賴以生存的植物及穀物，情況令人憂慮。 他說：「這是我投身養蜂業的其中一個重要原因。全球暖化和使用殺蟲劑，導致蜜蜂數量急跌，但不少植物倚賴蜜蜂授粉，人類約有七成食糧是由蜜蜂支援生產。」 在人口稠密的城市，無休止的發展令野生蜜蜂及其食物供應飽受威脅，加上熱帶風暴的破壞力有增無減，即使業界努力補救，蜂蜜供應依然不甚穩定。  解決問題的其中一個有效辦法，就是大量在城市養殖獨居蜂。焯成說，獨居蜂佔了全球蜜蜂的九成，生性溫馴，無需倚靠蜂巢存活，因此是家居養蜂的首選。用木頭和其他物料搭建小小的蜂箱，已可為獨居蜂提供基地。這些蜂箱可放置在家居或公園任何角落，在自然環境中增添蜜蜂授粉的機會。 在城市設置「蜜蜂酒店」的做法在全球越見普遍。他說：「這在台灣非常盛行，甚至深入學校，但香港仍需努力推廣。」 科大對促成佘焯成的「甜蜜」人生居功不少。他攻讀數學學位時，副修生態研究及中國研究，對全球暖化有一定認識，明白氣候變化如何影響地球。他亦熱衷與別人分享其所學知識。 現時，焯成既要打理補習社，又忙於在大嶼山和大帽山郊野公園附近建立生產基地、舉辦蜂場生態教育團向參觀者講解香港常見的花蜜植物、蜜蜂生活習性、採收蜜糖方法，以及設置蜜蜂酒店。

This month, we experienced the hottest day of the year as temperatures in Hong Kong reached 35.1 degrees Celsius. Countries across western Europe also struggled in record-breaking temperatures recently, with France hit the worst at 45.9 degrees in June. The grim situation appears to have been a repeat of last year's conditions. Although there are ongoing indepth analyses and further studies to examine the causes of individual extreme temperature events, many experts believe that extreme heat waves would not be feasible without anthropogenic climate change, meaning human activities are the main culprit for global warming ravages. Such an assumption has been proven by climate models - a complex computer simulation of physical processes and mathematical formulae used mainly to predict climate and understand how the climate system responds to elevated greenhouse gas emissions.

A recent Consumer Council survey has found that only two out of eight tested anti-bacterial handwash products can live up to their claims of having 99.9 percent efficacy in killing germs, sparking worries amongst the public. Advertisements often imply that bacteria in homes are harmful and must be eliminated by using any antibacterial or antimicrobial products available. However, Boston University's School of Public Health suggests only about 5 percent of bacterial species are disease-causing, in other words pathogenic. In fact, the pursuit of a germ-free environment is futile. Some bacteria are just impossible to eliminate with chemicals in the cleansing agents, or at the concentrations level of the chemicals we are commonly using. Even the so-called 99.9 percent efficacy must rely on perfect usage of the product.

The recent Extinction Rebellion movement in the UK protested against climate breakdown, biodiversity loss and the risk of social and ecological collapse. Protesters called for policies that can achieve a net zero carbon footprint by 2025, one of the 17 sustainable development goals agreed by world leaders at the United Nations in 2015. Meeting these goals requires more than addressing climate change. Sustainable development is a balance between the needs of the environment, society and economy in order to maintain a quality standard of life for both present and future generations. Many countries, including the UK, have implemented goal-specific measures in a bid to achieve the 17 goals, with voluntary national reviews to see if the measures are effective.

Air pollution is a major environmental and health concern in Hong Kong and the largest environmental health risk, according to the World Health Organization, tying it to seven million premature deaths globally in 2016. Yet many of us accept it as part of city living. In a bid to help city dwellers take their health into their own hands, HKUST's Institute for the Environment recently launched a game-changing mobile app that lets users monitor air quality to reduce their exposure to air pollution. Titled PRAISE-HK (Personalized Real-time Air-quality Informatics System for Exposure), the app provides real-time air quality and health risk information and forecasts, down to the street you are at, up to two days in advance, helping Hongkongers live a smarter and healthier life. One of the world-leading technologies behind the app is our dynamic transport modeling.

Our fishery gave birth to a love of seafood, but it is also contributing to the global fish stocks decline. We degraded it through overfishing, pollution and reclamation before building a fleet to ravage fisheries in other places. Many cities have actually done the same. Ironically, calls to save global fish stocks come from cities that sacrificed their own fisheries. Yet, Hong Kong also shows the way to a solution. It retains a resilient population of people who fish, those with the expertise and toughness to build a sustainable fishery, that is, such as those where catch volume and fishing practices allow for continual regeneration of stock, while enabling fishers to achieve a decent standard of living. People in the industry will overfish and abuse the ecosystem to provide more income if they can't afford a living. But our highly adaptable fishermen can demonstrate a global model for sustainable fishery.

By Miao Jia, Research Assistant Professor of Division of Social Science, HKUST By 2064, Hong Kong's number of elderly (aged 65 and older) will reach 2.58 million, accounting for 36 percent of the population. Today this percentage stands at 16, with one third of the elderly living in poverty. These staggering figures pose severe challenges to our society, thus studying the well-being of Hong Kong's elderly is vital to developing the right solutions. Since 2010, our Center for Applied Social and Economic Research team at HKUST has been conducting surveys of 3,200 families, 7,200 adults and 950 children every two years (The Hong Kong Panel Study of Social Dynamics), looking into how our society is transformed over time and how various government and social policies are influencing families.

承接去年成功推出「八大走飲管」運動，八所教資會資助大學將於今年3月11日發起「八大BYO (Bring Your Own )」運動，鼓勵師生減少使用即棄用具。 此運動標誌著八所大學將透過共同努力，減少即棄廢物，參與院校包括香港城市大學、香港浸會大學、嶺南大學、香港中文大學、香港教育大學、香港理工大學、香港科技大學及香港大學。 今年的運動以「自攜」為主題，鼓勵學生及教職員在校園用餐或購物時，自攜各種可重用物品，例如購物袋、水樽及餐盒等，藉此減少即棄物品的消耗，建立自攜減廢的校園文化。 為配合有關主題，八大校園內多間食肆將於3月11至17日期間推出優惠，讓自攜重用器具的顧客，享有最多低至半價的折扣。八大亦會圍繞同一主題，在各大校園舉辦活動，包括電影放映會、攝影展及市集等，鼓勵自攜重用器具，減少使用即棄產品。 各間大學亦已委任一名學生活動大使，與朋輩分享日常減廢心得，如何在生活中實踐自攜，感染身邊人積極參與，為環保出一分力。 香港大學行政及財務副校長兼香港可持續校園聯盟召集人康諾恩博士表示：「去年『八大走飲管』運動反應正面，我們十分高興能與各大學再度合作，營造校園自攜減廢的風氣。透過通力合作，八大將發揮積極作用，實踐減廢精神，締建高教界可持續發展文化。」 主辦「八大BYO 」運動的香港可持續校園聯盟，一直為香港高等院校師生提供平台，就共建可持續的未來此課題，進行知識交流和討論。 為推動大眾減少使用即棄塑膠飲管，聯盟於2018年舉辦「八大走飲管」運動，成功節省76,000支即棄飲管，藉此減輕堆填區之負荷。 更多活動詳情，請參閱：http://www.hkscc.edu.hk/activities/byo2019 八大BYO運動宣傳短片: https://youtu.be/lwYiTFwKheU   傳媒查詢:
