Earth Day, celebrated annually on April 22, may be the one day that transcends culture, language, and tradition. Doodler Sophie Diao shares some of her thoughts on the day and the paintings she created:

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. Each time you visit Google.com, you’ll randomly receive one of the five doodles. Keep refreshing to admire a different side of Earth’s immense beauty.

Scientists estimate the Earth’s age at over 4.5 billion years, but its Day has only existed for 46. 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.

Originally conceived by peace activist John McConnell in 1969, Earth Day as we know it was established by U.S. Senator Gaylord Nelson a year later. Concerned about humanity’s impact on the natural world, Nelson sought to raise public awareness of environmental issues by devoting a day to environmental  events and education. Since its inception, Earth Day has spread to nearly 200 countries, with millions of celebrants all around the world.

It’s a day to reflect. 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.

We live on a beautiful planet, and it’s the only one we’ve got. Happy Earth Day!
