Conference on Human Environment(the Stockholm Conference) to tackle the pollution caused by the industrial revolution during the 1960s and 1970s. In this conference, various topics including marine life, protection of resources, environment change, disasters related to nature, and biological change were discussed. This conference resulted in a Declaration on the Human Environment (Stockholm Declaration) and the establishment of an environmental management body, which later was named United Nations Environment Program(UNEP). UNEP was established by General Assembly Resolution 2997. Headquarters were established in Nairobi and Kenya with a staff of 300, including 100 professionals in a variety of fields, and with a five-year fund of more than US$100 million. At the time, US$40 million were pledged by The United States and the remainder by 50 other nations. The Voluntary Indicative Scale of Contribution (VISC) established in 2002 has the role to increase the supporters of the UNEP. The finances related to all programs of UNEP is voluntarily contributed by U.N. member states. The Environmental Fund, which all nations of UNEP invest in, is the core source of UNEP’ s programs. Between 1974 and 1986 UNEP produced more than 200 technical guidelines or manuals on environment including forest and water management, pest control, pollution monitoring, the relationship between chemical use and health, and management of industry.
