Climate change is real. It is happening right now, before our very eyes. We all have a lot to lose. So why haven't world leaders taken action? This video features a cross section of young persons asking the question, Why? Why Not?, a project of the Climate Reality Project. They have been workingin collaboration with WPP, the world's largest communications services group, and UN Secretary-General Ban Ki-moon on the #WhyWhyNot campaign to put pressure on world leaders, through their citizens, to make meaningful commitments on carbon emission reduction

Why? Why Not? In every language on the planet, children ask these questions over, and over, and over. They ask the first to understand the world around them, and they ask the second when they want to change that world.

We want people of all ages to ask those questions of their friends, their social networks and, most importantly, their elected representatives and keep asking them until the lies of the deniers and their vested interests run out.Published on Oct 1, 2014
