The calendar page for June 5, 1986 is devoted to World Environment Day and reflects growing Soviet attention toward environmental protection, endangered species, and the preservation of natural ecosystems during the late Soviet period.
The front side contains an illustration by artist L. Postnykh showing a child sitting among flowers beneath the words “Not for War.” The image combines themes of peace, childhood, and environmental protection, presenting nature as something fragile and deserving care rather than destruction.
Below the illustration, the page marks World Environment Day and also notes the opening of the International Meeting of Communist and Workers’ Parties in Moscow in 1969. Like many Soviet calendars, the page combines environmental themes with political and historical references.
The reverse side discusses the “Red Book,” the internationally recognized catalog of endangered animal species. The article explains the publication of regional Soviet Red Books and describes threats to wildlife caused by hunting, habitat destruction, and human activity.
The text mentions rare mammals, birds, fish, reptiles, and insects, while also giving examples of species whose populations were restored through conservation measures. The article presents environmental protection as both a scientific and moral responsibility.
