1992年6月,联合国将在巴西就环境与发展问题召开各国首脑会议。这是继1972年联合国在瑞典召开第一次人类与环境大会后最重要的一次环境会议。这次会议将讨论有关环境与发展的一系列重大问题,并通过《地球宪章》和《21世纪行动纲领》等重要文件。因而已引起国际社会的普遍关注,许多有识之士把这次会议将要讨论的问题看成是本世纪末到下世纪初人类社会所而临的最重要的问题之一。 In June 1992, the United Nations will convene summits of countries on environment and development in Brazil. This is the most important environmental conference since the United Nations held its first human and environmental conference in Sweden in 1972. The conference will discuss a series of major issues related to environment and development and adopt important documents such as the Earth Charter and the Agenda for Action for the 21st Century. As a result, widespread concern has been drawn by the international community. Many people of insight see the issue to be discussed at this meeting as one of the most important issues facing human society from the turn of the century to the beginning of the next century.
