This document discusses the establishment and purpose of World Environment Day by the United Nations. It notes that World Environment Day was established in 1972 on June 5th by the UN General Assembly to mark the opening of the Stockholm Conference on the Human Environment. This led to the creation of the UN Environment Programme to raise awareness of environmental issues and encourage public action and political discussion around addressing problems facing the global environment. The day is now an occasion each year to discuss environmental problems and ways to take corrective action toward protecting the environment.
