    Food production does great harm to our environment. There are many procedures involved in the manufacture of food that result in greenhouse gases and other pollutants. Some procedures require the consumption of large amounts of fossil fuels, such as the transportation and storage of food products. Other factors that cause great damage to our environment include the overuse of fresh water.

    The production of beef is more damaging to the environment than that of any other food we consume. Raising large numbers of cattle requires the production of large amounts of food for the animals. It's estimated that producing one pound of beef requires seven pounds of feed.

    Land use is also a problem. If the cattle are free-range cattle, large areas of land are required for them to live on. This has led to disastrous forest cutting and the loss of rare plants and animal species, particularly in tropical rain forests in Central and South America.

    Another problem specific to beef production is methane emissions (甲烷排放). Although many people are aware of the damaging effects of carbon dioxide, they don't realize methane's global warming potential is 25 times worse, making it a more dire problem.

    Unfortunately, beef consumption is growing rapidly. This is the result of simple supply and demand factors. Specifically, there are two main causes of demand that are encouraging the production of more supply. First, the increase in the world population means there are more people to consume meat. The second factor is socioeconomic advancement. As citizens in developing nations become financially stable, they can afford to buy more meat.

    Therefore, one way to reduce the greenhouse gas emissions is for people around the world to significantly cut down on the amount of beef they eat.

    China has recently published its first artificial intelligence (AI) textbook for high school students, following a plan by central government last year to include AI courses in primary and secondary school.

    Under the joint efforts by the research center for MOOC at East Normal University and AI startup Sense Time Group, the nine-chapter textbook, named Fundamentals of Artificial Intelligence, was written by eminent scholars from well-known schools nationwide, Xinhua reported on Sunday.

    It includes the history of AI and how the technology can be applied in areas such as facial recognition, auto driving and public security.

    “The textbook focuses not only on basics of AI, also on practical use of AI in daily life,” said Chen Yukun, a professor at East China Normal University, who is also a contributor to the book. At present, about 40 high schools across the country have joined the first batch(批)of AI high education pilot program, by introducing the textbook in curriculum(全部课程).

    “The AI sector is facing a talent shortage globally. The publication of the book is a breakthrough as it takes AI technology out of the 'ivory tower' and makes it part of high school learning,” said Lin Dahua, a professor at the Chinese University of Hong Kong.

    As early as 2016, the governments had estimated that demand for AI professionals may suddenly increase to 5 million in the coming years.

    “Many industries in the future will benefits from AI technology, so the aim of the related courses should be to let students learn the basic idea and methods of AI,” Lin said.

    China has made significant progress in technological research and development in recent years. According to a report released by US-based venture capital(风险资本)database CB Insights in March, China has for the first time surpassed the United States in equity funding(股权融资)to AI startups.

    Every year, millions of people head to London's Trafalgar Square to see Nelson's Column, and the four lion statues that “guard” it. And last month, during the London Design Festival, a bright red lion sculpture was added to the collection.

    But this was more than just a statue: It had a large open mouth, with an LED screen inside it. At the same time, passersby could type in random words on a screen close to the lion, which were used to produce an AI-created poem. The most interesting part of the poems lies in their randomness, as the words that people choose to enter include many things, such as the time, the weather and their mood. In the daytime, the finished poem appeared on the LED screen, but at night, it was projected (投射) onto the lion's body and the famous Nelson's Column, in a 1ovely light display.

    Es Devlin, the sculpture's creator, was inspired by the history behind the four historic lion statues. Edwin Landseer, the designer of the lions, wanted them to look much more animated, but Queen Victoria refused his plan. This made Devlin wonder, "What if we could give a lion a poetic voice?" According to Devlin, although England has seen many poems about national identity in recent years, these works have been lacking imagination. "I wanted to make a piece that was poetic and collective" he told BBC News.

    After standing for almost 180 years, the purpose of Trafalgar Square has changed over the years. But thanks to the high-tech lion and its poetry, the square is standing the test of time.

    As the days get shorter and the chilly weather rolls in, we all want to curl up in a blanket and hibernate until spring rolls around. But making time to get outside in the sun, even when it's cold out, could have bigger mood benefits than you might realize.

    While the link between sunshine and mental health is nothing new, new research from Brigham Young University (BYU) has shown that the association may be even stronger than previously realized. It finds that sunlight exposure is by far the greatest weather-related factor determining mental health outcomes. In other words: more sunshine, more happiness.

    For the study, a psychologist, a physicist and a statistician from BYU teamed up to compare daily environmental data from the university's Physics and Astronomy Weather Station with emotional health data archived by day for 16,452 adult therapy patients who were being treated at the BYU Counseling and Psychological Services Center.

    Exposure to sunlight is a significant factor in seasonal affective disorder. Research has shown that the brain produces more of the feel-good neurotransmitter serotonin on sunny days than it does on darker days. What's more, lack of sunlight is linked with lower vitamin D levels, which in turn has been correlated with depression and low energy.

    If you're getting enough sun, your emotions should remain relatively stable, the researchers found. But as the amount of sunlight in the day is reduced, levels of emotional pain can soar. Other weather variables including temperature, pollution and rain were not found to have an impact on mental health.

    “We were surprised that many of the weather and pollution variables we included in the study were not significantly correlated with clients' scores on the distress measure once we had accounted for suntime," Dr. Mark Beecher, a professor of psychology at the university and the study's lead author, told The Huffington Post. “People tend to associate rainy days, pollution, and other meteorological phenomena with sadness or depression, but we did not find that.”
