Google collaborates Earth Day 2018 with renowned ethologist and conservationist Dr Jane Goodall to speak about our planet's future.

In the illustrated video of Doodle, she speaks about the conversation efforts and animal welfare.

The search engine giant partnered with Jane Goodall and The Jane Goodall Institute to create the graphic, through which Goodall shares her own personal message with the world.

According to Google, the goal is to tell her story and touch on "what we can all do to have a positive impact on our planet."

Goodall says in the video, "Out in the rainforest, you learn how everything is infinite, and how each different species, even though it may seem insignificant, has a role to play in the tapestry of life. What better day than Earth Day than to really make a determined effort to live in better harmony with nature."

She continues, "Every single individual matters, every single individual makes some impact on the planet every single day, and we have a choice as to what kind of difference we're going to make."

Every year, Earth Day is celebrated on April 22 worldwide, and with the Earth Day-themed doodle, Google supports and promotes the environment protection.

The theme of Earth Day 2018 is the end of Plastic use.

At a UNESCO conference in San Francisco in 1969, peace activist John McConnell proposed that a day should be set aside to honour the Earth and the environment.

The first Earth Day took place the following year in 1970 and marking it were 2,000 colleges and 10,000 schools across the US.

Now it is celebrated in 192 countries across the world by around one billion people.

Every year, hundreds of millions of people march, sign petitions, plant streets, clean up their streets and meet with elected officials in a day of action marking the day.

Earth Day 2018 is focused on ending plastic pollution, especially the "single use and throw away" culture associated with the material.
