It’s Earth Day today and Google is celebrating this day in its customary style by doodling colourful illustrations of our natural landscapes to remind us what a beauty Earth is.

Earth Day, observed annually on April 22 since it began in the 1970, is “the one day that transcends culture, language, and tradition,” Google says.

To celebrate the vastness of our planet’s diversity, Google has showcased five different biomes which appears each time one visits the site’s homepage. You just need to keep refreshing to admire a different side of Earth’s immense beauty, all day today.

Amidst the wonderful illustrations, you will have to struggle a bit to find the Google logo which has been smartly blended with the surrounding landscapes. Another interesting thing is that each illustration showcases an animal who inhabits that particular biome.  Let’s have a look:

A tortoise comfortably nestled in a Desert

The red fox running wild in the Forests

An octopus playing in an underwater coral reef in an Ocean

An elephant roaming in the grass savanna at sunset

The solitary polar bear on an ice sheet in the Tundras

Google’s doodler Sophie Diao who has illustrated these awesome pictures said in a blog post

“I am personally in awe of nature’s persistence and creativity. Our planet – with its alternate scorching heat and bitter cold, its jagged peaks and deep trenches – may not always be kind to its inhabitants. Yet somehow the flora and fauna of Earth manage to thrive. On a day like this, we remember and celebrate our home in this great and stunning ecosystem.”
