Since its inception, World Environment Day has spread to over 140 countries and has had its main celebratory event held on all six of Earth’s inhabited continents. A special anthem called “Earth Anthem” is often sung at these events.
Themes vary from year to year, but recurring emphases include such things as Earth as our common home and the need to protect it and its life forms, the vital importance of water, the need to protect the ozone layer, the ill effects of excessive deforestation, the plight of “wildlife crimes”, and leaving our children and grandchildren a healthy, beautiful planet.
