Finally, environmental conservation cannot be achieved only by either a person or a nation. We have to raise individual cooperative consciousness within society and nations. In the same manner, the environmental law has to be developed in line with law practitioners. However good the laws theoretically are, their true values are really defined by practice or application. The improvement of legal practitioners is therefore necessary especially judges dealing with environmental cases, who need to have knowledge and understanding on environmental law which is complicated. Legal knowledge alone is not sufficient. Various areas of knowledge are required to solve problems or disputes related to environment as the judge is entrusted with the exercise of suitable discretion over cases.
