The UN has designated Sunday next, 22 April 2018, as Mother Earth Day and the following is an extract from the related UN site:
International Mother Earth Day is celebrated to remind each of us that the Earth and its ecosystems provide us with life and sustenance.
This Day also recognizes a collective responsibility, as called for in the 1992 Rio Declaration, to promote harmony with nature and the Earth to achieve a just balance among the economic, social and environmental needs of present and future generations of humanity.
International Mother Earth Day provides an opportunity to raise public awareness around the world to the challenges regarding the well-being of the planet and all the life it supports.
