Actress Julia Roberts has done the voiceover in an impactful video uploaded on the YouTube channel of the organisation Conservative International.

In the video, which is one minute and 58 seconds long, the actress speaks from the point of view of Mother Earth.

She says in the video: "Some call me nature, others call me mother nature. I have been here for over four and a half billion years -- 22,500 times longer than you. I don't really need people but people need me. Yes, your future depends on me. When I thrive, you thrive. When I falter, you falter, or worse."

She goes on to make a powerful statement on behalf of earth as strong visuals add impact to her voice.

"But I have been here for eons. I have fed species greater than you and I have starved species greater than you. My oceans, my soil, my flowing streams, my forests, they all can take you or leave you," she says.
