Today’s Thursday is Earth Day

Something for the Google-pic collection – today: Earth Day.

Looks like directly from “Avatar”, doesn’t it?

Until today I didn’t know that Earth Day even exists, however, Wikipedia tells you more about it. And it is not just any Earth Day, it is the 40th this year!

So there will be some activities around it, some of it one can follow here on the official website.

I wonder how much has changed in 40 years? How and what did people do on the very first Earth Day, what where the issues then, in comparison to today?

Anyone of you who actively did anything related to Earth Day or took part in any event?
