For Earth Day 2013, Google is celebrating with an interactive doodle that lets you experience much of what nature has to offer - in animated form, of course. Google's Earth Day doodle lets you change the seasons, weather, moon, and more.
"Today we are celebrating Earth Day with an interactive doodle that captures a slice of nature's subtle wonders. We hope you enjoy discovering animals, controlling the weather, and observing the seasons. Use the sightseeing checklist below to make sure you do not miss anything!" says Doodler Leon Hong.
Indeed, Google has provided a Doodle checklist. So, click around and have fun.
Earth Day, as we know it, is celebrated on April 22nd. Back in 1969, the first Earth Day was proposed at a UNESCO conference in San Francisco to be celebrated on March 21st. A month or so later, U.S. Senator Gaylord Nelson held an additional Earth Day on April 22nd, as an environmental teach-in. In 1990, the April celebration went international, and it is currently celebrated in nearly 200 countries worldwide.
Last year, Google's Earth Day doodle was also animated, though not quite interactive. The doodle was a time lapse photo of flowers blooming and eventually forming the Google logo.
