Newswise — Earthwatch, the international environmental organization, announced phase two of its partnership with technology start-up TurnTo today, just a year and a half after the non-profit helped to provide the inspiration behind the e-commerce venture.

TurnTo is based on a simple idea " that friends and others in your network are often the best source of advice when making a purchase online. The opt-in service drives word-of-mouth by showing prospects what trusted contacts have bought. TurnTo CEO George Eberstadt, a trustee of Earthwatch, was inspired to create the service when he volunteered to develop the organization's social networking profile.

Eberstadt said, "I was struck by how often, when I mentioned Earthwatch, people said, 'I've been thinking about going on one of their expeditions for ages. What's it like?' Turns out, lots of my friends were interested in Earthwatch and just didn't know that I was a potential source of information. That's when the first light bulb went off. TurnTo was born from the idea that any time anyone in my extended network visited the Earthwatch website, they should see me as a reference. The goal was to provide a simple non-intrusive way for people to help their friends and spread the word about Earthwatch."

Caroline Chisholm, Head of Marketing and Communications for Earthwatch, said Earthwatch has been testing the TurnTo system for several months, and the feedback has been very positive. "So now we're launching phase two of the roll-out," Chisholm said. "We're placing the TurnTo widget in many more locations throughout the Earthwatch website, and we'll be actively reaching out to all our past volunteers and other members of the Earthwatch community to invite them to share their Earthwatch experience through the TurnTo system."

"We're delighted to be teaming up with TurnTo. Over the years, thousands of volunteers have been inspired to help Earthwatch because they heard about us through friends and family. In this digital age, the word-of-mouth effect is driven by social networking. People use the internet for all their needs " food, entertainment, real estate, even finding the perfect partner! Now, with a little help from their friends, people can also make choices about their volunteering options online," Chisholm said.

Since 1971 Earthwatch has pioneered its unique 'citizen science' model, giving ordinary people the opportunity to work alongside leading researchers to investigate some of the world's greatest environmental challenges.
