To celebrate this year's Earth Day, Google Doodle is displaying five different logo designs that feature creatures in varying major biomes.

The designs are painted by Google Doodler Sophie Diao who took inspiration from the earth's rich habitats. These landscapes include the tundra, forest, grasslands, deserts and the ocean.

Last year, the same concept was applied but focused on uncommon animals instead to represent their different backgrounds. These animals were the Rufous hummingbird, a dung beetle, moon jellyfish, veiled chameleon, Japanese macaque and puffer fish.

Today, Diao chooses to also highlight five major biomes to represent the earth's natural biodiversity.

"The vastness of Earth's diversity makes it an intimidating topic, but in the end I chose to highlight Earth's five major biomes: the tundra, forest, grasslands, desert, and coral reefs. In each illustration, you'll find one animal who's been singled out for their 15 minutes of fame," Diao writes.

The aquatic landscape features an octopus crawling across the ocean floor, the desert biome features its durable plant life and a tortoise, the grasslands feature an elephant in the background against a picturesque sunset, the forest features white trees and a red fox for contrast, and lastly, the tundra biome features a polar bear and its aurora lights.

These amazing representations by Diao randomly display on Google's homepage and can be accessed by repeatedly refreshing the page.

Despite the earth's ancient age, roughly 4.5 billion years old, Earth Day has been annually only celebrated 46 times since 1970, during which it was officially declared by U.S. Senator Gaylord Nelson. The idea was originally pushed by John McConnell, an activist, in the previous year where a devastating oil spill had occurred in California.

Earth Day was conceived because of our civilization's negative impact against the world. This realization aims to "raise public awareness of environmental issues by devoting a day to environmental events and education."

But why stop there?

How about we all, as grateful inhabitants of this magnificent world, celebrate Earth Day every day to give back to the Earth what it has freely given us. Make each day a day to reflect and help keep the Earth thriving, for "it's the only one we've got."
