Give Earth a Hand - http://www.giveearthahand.com - is a social network supporting non-profit projects worldwide which work towards helping our planet.

We are currently looking for new members to sign up to help spread the word (it's for free) and if they like the idea, they can sign up for 2 Euros and join the 'Earth Chain', which will allow 1.8 million people to support these non-profit projects. Each member receives an individual figure in Google Maps showing who they are and it links to your profile.

My name is Jonathan Young. I am 35 years old, live in Hamburg, Germany with my family and work currently as the German site executive for a large Internet-based travel company. Time and time again I have had ideas for Internet-based projects, ideas which could get noticed by many people and at the same time aim to reach a goal which would make me proud of my achievement. The idea of creating a social community with a donation funded virtual human chain around the whole world came early February 2007 and I haven't stopped developing the site since. "Give Earth a Hand" will allow me to create a network of people around the world to help support projects aiming at fighting global warming and the general ecological downfall happening on our planet.
