On the cusp of the 20th anniversary of the world’s first Earth Summit, held in Rio de Janeiro, Brazil, in 1992 and scheduled there again this coming June, The Regeneration Project is posting a series of videos and other content to spur thought and, more specifically, action.

One video, entitled Our Scarcest Resource is Time, underscores both the urgency and slow pace of progress in the two-decade fight against carbon emissions and climate change. “Are we at a critical point?” asks Jonathan Porritt, founder of Forum for the Future in his interview. “We’ve been at a critical point for years.”

Sha Zukang, secretary general of the upcoming Rio+20 summit, is even more direct. “It’s high time for the international community … to renew and reconfirm their commitment and also come up with practical measures to implement their commitment,” he says. “Otherwise, we are really wasting our time, and we don’t have much time to waste.”

Check out the video Our Scarcest Resource is Time and surf around The Regeneration Project website, a collaborative effort to improve “sustainable development strategy, increase credibility, and deliver results at greater speed and scale.”
