New Delhi: With the change of seasons as the theme, the animated Earth Day 2013 Google doodle continues in an unending loop moving from one day to another and from one season to the next.
It is noon on a bright spring day on the Google Earth Day 2013 doodle. Clicking on the play button on the blazing sun sets the day and the doodle in motion. The sun moves westwards to set and the moon rises in the sky and the cycle of seasons that control so much on the planet is replayed on your browser.
In spring there is a little snow on the mountain tops and the flowers and the plants have just began to bloom, followed by summer and then a cold frozen where the only sign of life are the fishes cricling in the stream.
Earth Day is held every year to highlight green issues with events being held around the world to demonstrate support for environmental protection.
First ever Earth Day was held in 1970, although the name and concept was pioneered a year earlier by activist John McConnell.
