Toward 10.9 Billion: Challenges of Global Population Growth

July 29, 6:00 pm - 7:00 pm

Presented in partnership with the International Relations Council.

It took hundreds of thousands of years for the global population to reach 1 billion people, and just 200 years later it has skyrocket to over 7 billion. The World Population Report now estimates that the human population will swell to 10.9 billion before the end of the century. Driven largely by advances in medical care and improved living standards, how will this rapid growth impact our environment and communities? In this discussion, experts will examine the potential outcomes of this considerable population increase and how it will affect people and our planet.
