Internet giant Google is commemorating Earth Day on Monday by displaying an Earth Day themed doodle on its homepage.
The elaborate and interactive doodle represents an ecological system spanning all the four seasons and different phases of the sun and moon. This is of Google's 13th doodle representing Earth Day.
Clicking on the sun makes it move westwards and brings out the moon in the night sky. A click on the clouds brings in rain and snow.
The doodle shows animals peeping out from caves and burrows, and fishes circling in the stream. The nights are lit with fireflies.
Hovering the mouse over the plants strewn in a 'G' pattern makes flowers bloom. The flowers, trees and stream of the enchanting forest spell out the Google logo.
Google directs users to earthday.org when clicked on the small magnifying glass sign on the right side of the doodle.
"Climate change can seem like a remote problem for our leaders, but the fact is that it's already impacting real people, animals, and beloved places," the website stresses.
"Help us personalize the massive challenge climate change presents by taking a photo and telling your story."
Earth Day was coined by peace activist John McConnell in 1969 at the UNESCO Conference in San Francisco. The day was first celebrated on 22 April, 1970. Currently, 192 countries observe Earth Day.
