With the popularization of online learning, governments can save more money in education instead of supporting other fields such as the medical sector or commercial. Obviously, supporting a school requires continuous investment in many areas such as hundreds of classrooms, teaching facilities, social services, etc., while online education is hardly in demand in these areas. Perhaps this is why governments today are willing to encourage the development of online education. Additionally, e-books and other online study materials can save countless amounts of paper, which is a great benefit to natural resources..
