Towards a Greener, Better World with Jeffrey Sachs

World-renowned economist Dr. Jeffrey Sachs believes humanity can leap forward with science and technology – but only if we drop our primeval addiction to war and conflict. We can create new vaccines in less than a year or measure water below ground using satellites in spaces, but political institutions are still locked in a 50,000-year-old "Us vs. Them" mindset that prevents global cooperation and advancement. With a broader, more inclusive worldview, Dr. Sachs says, we can create a more sustainable planet.
