If all the food that's thrown away in three American cities could be saved, it would provide 68 million meals for people who don't have enough to eat, according to a recent study.

    The researchers found that, in the cities they surveyed（调查）, more than a kilogram of edible food per person is wasted each week. Edible food is food you can eat. It doesn't include things like apple cores（果核）, egg shells, or bones from meat. Fruits and vegetables were the most common edible foods found in the dustbin, followed by food leftover from meals. Eggs, bread and milk were also commonly thrown out.

    The people taking part in the survey gave several reasons for throwing edible food away. Most said the food went off. Some said they weren't interested in eating leftovers. A few said the food had passed the “Best Before” date printed on the label（标签）. When food is wasted—by families, restaurants or grocery stores—we are also wasting all of the resources that go into producing that food. That means we are wasting water, land, energy and labour, as well as the fuel needed to transport food.

    A lot of food is wasted before it even reaches the grocery store（食品杂货商）. Some food is damaged while it is being transported from the farm to the stores. Fruits and vegetables that don't look attractive enough don't even get put onto the shelves because most people won't buy them. Grocery stores, restaurants and hospitals also waste a large amount of food. The researchers suggest that grocery stores should donate any food that is still okay to eat to homeless shelters, instead of throwing it away. Prepared meals from hospitals or restaurants could also be donated to shelters.

    The latest IPCC report does not mince words(直言不讳地) about the state of our planet: we must act now to achieve global change at a scale that has “no documented historical precedent(先例)” in order to avoid the climate disaster that would result from a 2 degree C rise in average global temperature. Climate change already affects the world's most helpless people including poor rural communities that depend on the land for their livings and coastal communities. Indeed, we have already seen the clear asymmetry(不对称) of suffering resulting from extreme weather events, such as hurricanes, floods, droughts, wildfires and more.

    So far, advocates and politicians have tended to focus on reducing fossil fuel(矿物燃料) consumption through technology and/or policy, such as a sharp carbon tax, as climate solutions. These proposals are, of course, essential to reducing manmade carbon emissions(排放)-71 percent of which are produced by just 100 fossil fuel companies.

    Yet the international focus on fossil fuels has overshadowed(使......显得不重要) the most powerful and cost-efficient carbon-capture technology the world has yet seen: forests. Recent scientific research confirms that forests and other “natural climate solutions” are absolutely essential in reducing climate change. In fact, natural climate solutions can help us achieve 37 percent of our climate target, even though they currently receive only 2.5 percent of public climate financing.

    Forests' power to store carbon dioxide through the simple process of tree growth is staggering: one tree can even store an average of about 48 pounds of carbon dioxide in one year. Recent research show undamaged forests are capable of storing the same amount of the carbon dioxide emissions of entire countries such as Peru and Colombia.

    For this reason, policy makers and business leaders must create and strengthen ambitious policies to prevent deforestation, and support the sustainable management of standing forests in the fight against climate change. Protecting the world's forests ensures they can continue to provide essential functions aside from climate stability, including producing oxygen, filtering water and supporting biodiversity. Not only do all the world's people depend on forests to provide clean air, clean water，oxygen, and medicines, but 1.6 billion people rely on them directly for their livelihoods.

    A university in Nanjing, Jiangsu province, has installed facial recognition systems in classrooms to monitor students' behavior, sparking a heated debate online. China Pharmaceutical University recently installed the systems in two pilot classrooms as well as school gates, dormitory entrances, the library and laboratory buildings.

    Xu Jianzhen, director of the university's library and information center, told TbePaper.cn that the systems will help teachers check student attendance and monitor behavior during the lectures. "In the past, some students just checked their attendance and ditched the class or asked other students to check the attendance for them. Now with facial recognition, that would no longer be a problem," he said. "The moment you enter the classroom, the camera will monitor you all the way through and can tell how long you lower your head, whether you're playing with a smart phone, whether you're dozing off or reading other books," he added.

    The news has raised wide debate on Chinese social media, with many questioning if the cameras will violate students' privacy. A Sina Weibo user said: "I oppose such methods, and it is not clear whether the systems are developed by the school itself or by third parties. If it is the latter, is there any regulation of security? Where will the information be sent and stored?"

    Gan Xiangsi, a senior student from the university, said she welcomed the systems being applied in dormitories and libraries as this can help prevent personal belongings being stolen，but it is not necessary to use such technology in the classroom. "If the teacher teaches well，the students will be interested," she said. "On the contrary, this kind of monitoring will make everyone feel resistant."

    China Pharmaceutical University is not the first university to use facial recognition technology on campus. Many universities across the country have installed cameras at campus entrances to ensure safety. But many are also hesitant when it comes to applying such technology in classrooms.

    "This issue has been debated for quite a long time," Chu Zhaohui, a senior researcher at the National Institute of Education Sciences, told China National Radio. According to Chu, teachers and students who are under observation might not behave as they normally would since they know they are being watched. "Cameras should not be installed in classrooms merely for effective teaching purposes," Chu said, as teachers are also being observed. He agreed that "students' privacy needs to be protected". He also said that not putting classrooms under control is an important principle. "If you don't follow this principle, students will falsify and disguise their state of listening，and teachers may also not perform as well. Then real teaching will not occur," he added.

Over the years, electronic commerce or e-commerce has grown rapidly. The rise of e-commerce large enterprises such as Amazon and Alibaba in the mid-90s changed the face of the retail (零售) industry. E-commerce may be thought of as an open, global marketplace or a digital version of mail-order catalogue (目录). Nearly every imaginable product and service is available through e-commerce dealings these days.

Many young entrepreneurs have dived into the e-commerce world, ambitious and hoping to succeed. Some, like Mitchell Zvagelskiy. Zvagelskiy is the co-founder of Scale Online, a fast-growing startup in California and runs several e-commerce stores. Zvagelskiy and his business partner began opening online stores and building a team to grow them, allowing the stores to earn as much as $100.000＋ in monthly revenue. Zvagelskiy owes his success to teamwork and his willingness to seize opportunity.

"Being able to do this all by the age of 20 is something I didn't expect and would not be able to do if I constantly listened to other people and just went the typical college then job route," he said. "Life can change fast if you change fast."

Thanks to the rapid success of his YouTube channel, Mitchell has been able to not only make great profit from his companies, but help others in starting and growing their own e-commerce stores too. "My meaning of success arises from my relationships with other people," he said. "By focusing on building strong relationships with others, I'm able to partner up and work with like-minded individuals in finding market opportunities and solving whatever problems people are facing."
