SAPPORO — After years of broken promises and ignoring problems until they turn into crises, it is time for the Group of Eight leaders to stop talking the talk and start walking the walk when it comes to climate change, poverty and human rights issues.

That was the message international nongovernmental organizations delivered in Sapporo on Sunday, the opening day of the People's Summit 2008.

The three-day NGO summit, which bills itself as the alternate G8 summit of industrialized nations, drew hundreds of activist leaders from around the world.
