The world faces a global refugee crisis, with 65 million people displaced. David Miliband, drawing on his family's refugee history and political experience, argues that failing refugees betrays our shared history, values, and interests. He explores the crisis from the Middle East to Europe, emphasizing that both governments and citizens must act.

Miliband champions upholding human nature against divisive rhetoric, defending the post-WWII international order while advocating for its reform. Watch his webcast for insights on this critical issue.

An optimistic message suggests human-caused climate change will be largely solved within 10-15 years, driven by exponential changes we often underestimate. History shows we consistently misjudge the speed of transformational shifts, like the move from horses to automobiles or America's journey to oil independence.

We are seeing this underestimation again in the transition from a fossil fuel to a low-carbon economy. This perspective comes from David Leuschen, Co-Founder of Riverstone Holdings, a private equity firm focused on energy, and former Goldman Sachs executive.

Dr. David Zaber, an environmental consultant specializing in sustainable natural resources and agricultural management, holds a Ph.D. from the University of Michigan. His talk explores how human behavioral ecology reveals resource use conflicts. He emphasizes that evolved human perception often causes people to overlook relevant environmental problems, hindering consensus and solutions.

Zaber argues that bridging this "Perception Gap" is crucial for effective environmental activism and protection. With an M.S. from the University of Illinois and extensive experience at organizations like Defenders of Wildlife, he currently works to protect Great Lakes forests and wildlife.
