2. "Net Green" will soon become the hottest hot word in the second half of 20 16. The concept of "net green" was first put forward by a group of urban white-collar workers. Because white-collar workers can't go to work without computers and mobile phones, they surf the Internet for eight hours every day during college, which leads to some health problems, such as cervical spondylosis and eye diseases. Even studies have shown that a sedentary life will increase the risk of cancer. Therefore, this group of white-collar office workers advocate green internet access, reduce sedentary time, go out to exercise more and feel green. Their slogan is to be "green online" instead of "network celebrity"! The concept of "net green" was born.
