One Day to Save the World. In 1972, the United Nations General Assembly established this observance to raise environmental awareness across the globe. Beginning in 1974, the observance has been held annually on June 5, a date that commemorates the start of the landmark 1972 United Nations Conference on the Human Environment, in Stockholm, Sweden. Each year, World Environment Day focuses on a particularly pressing environmental issue, such as wildlife conservation, climate change, or our vital connection to nature. For official celebrations, a different host country is chosen yearly. In addition, many other countries also hold events, such as bicycle parades and tree planting. Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it’s the only thing that ever has.” –Margaret Mead, American anthropologist (1901–78)”
