A wide range of organizations around the world today makes an event which aims to save the Earth, and as always google participated in each event International, we can see from the google logo today.
And here's a video that I can be from earthday.org which invites us go green together.
It's supposed to be for those who settle in this planet had to protect and preserve it. Because condition of the earth that is increasingly unstable it will harm us too later. Much we can do, like planting a tree, bike to work, turn off lights when they're not in use, etc.
The Earth needs our help now more than ever, not just words, but also requires action.
Together we save the earth and make a difference. =)
