Ticklish pandas, frolicking penguins, a growling lion, a cascading
waterfall, waterfall climbing fish, a fish devouring bear, birds,
butterflies, a koala and a jumping frog get together on an animated
and interactive Google logo to celebrate the 42st Earth Day.
The first Earth Day was celebrated on April 22, 1970 and was founded
by US Senator Gaylord Nelson. The original Earth Day was attended by
about 20 million Americans. The Earth Day movement went global in 1990
and is now celebrated in over 175 countries across the globe. April 22
was officially designated as the international Earth Day by the United
Nations in 2009
