Hardly mentioned by the talking heads, yesterday was according to Wiki:
World Environment Day (WED) is celebrated annually on 5 June and is the United Nations’ principal vehicle for encouraging awareness and action for the protection of the environment. First held in 1973, it has been a platform for raising awareness on environmental issues such as marine pollution, overpopulation, global warming, [[sustainable development]] and wildlife crime. World Environment Day is a global platform for public outreach, with participation from over 143 countries annually. Each year, the program has provided a theme and forum for businesses, non government organizations, communities, governments and celebrities to advocate environmental causes.
World Environment Day was established in 1972 by the United Nations at the Stockholm Conference on the Human Environment ( 5–16 June 1972), that had resulted from discussions on the integration of human interactions and the environment. Two years later, in 1974 the first WED was held with the theme “Only One Earth”
