WASHINGTON, April 22 (UPI) -- Google is celebrating Earth Day 2016 with a set of five Google Doodles highlighting the planet's biomes.
In random order, site users will see illustrations by Doodler Sophie Diao which offer a creative look into habitats like the desert, coral reefs, grassland, the forest, and the tundra.
Each doodle includes the image of one animal found in these biomes, including the tortoise, octopus, elephant, red fox and polar bear.
"Scientists estimate the Earth's age at over 4.5 billion years, but its Day has only existed for 46," artist Diao wrote in her explanation for the April 22 Doodles. "Earth Day inspires all of us to appreciate our big blue and green orb with events big and small, ranging from family hiking trips to citywide recycling initiatives."
Earth Day was founded by Gaylord Nelson in 1970, when pollution was arguably at its most widespread, and continues on as an annual celebration of the natural. The Earth Day Network has devised a map of global events taking place to benefit and honor our blue and green planet.
In North America, such events as music festivals, city-wide cleanups, tree planting events, Earth Day picnics, and 5K runs are just a few of the hundreds of registered events occurring Friday. Every inhabited continent is saturated with Earth Day festivities, check out this map to find one near you.
The U.S. Environmental Protection Agency is also making moves to help the planet this Earth Day by providing tools to aid citizens in cutting food waste. The agency is asking those interested to pledge themselves as an EPA Food Steward in order to cut down on the amount of methane -- a greenhouse gas -- that is released into the air by rotting grub.
"Much of the food that is discarded in landfills is actually safe, wholesome food that can be used to feed vulnerable populations," the EPA said on its website.
