At the 70th UN General Assembly in 2015, the world unanimously adopted the Sustainable Development Goals (SDGs), which are 17 goals that the world should practice together by 2030. SDGs are becoming more important as an international commitment that includes 'comprehensive life values' such as justice, human rights, community, and nature as well as environmental protection. And today's schools provide Education for Sustainable Development(ESD) to solve these global problems and to reach the SDGs. However, there are many limitations and difficulties in providing such ESD in the school field. First, schools are having a hard time getting students to network smoothly with global people. Networking is important for students to cooperate with people around the world, so the global networking problem that students are experiencing is an important problem to solve quickly. Second, there is a limit to students experiencing and empathizing with global problems(environmental issues, human rights issues, etc.). This is important because it is difficult for students to solve the problem if they cannot empathize with it. Third, schools are having a hard time creating habits and environments for students to solve social problems in a self-directed way. Students must participate voluntarily to solve social problems. If these difficulties continue, we will have problems in implementing ESD in the school field, which will further hinder the world from reaching its Sustainable Development Goals(SDGs).
