Program Overview

The 2020 U.S. Census Bureau shows that the central Ohio region experienced the fastest population growth in the Midwest in the last decade, and Columbus was one of only 14 cities nationwide to add more than 100,000 residents. With population growth comes the need for jobs, housing, transportation, and infrastructure – is this form of growth sustainable for our region? Do we have the social and environmental systems in place to support this growth?  

To provide a global perspective, the landmark MIT study Limits to Growth demonstrated fifty years ago that continuous growth is not sustainable and will lead to a collapse of human society. This position received global attention again this summer when Gaya Herrington (director, Sustainability Services, KPMG) updated the study’s original research models using decades of observations and current data. Her work published in the Journal of Industrial Ecology in June 20211 demonstrates alarming support for the Limits to Growth original thesis on a global scale – that humanity cannot sustain unrestrained economic growth. What does this mean for the Midwest’s fastest growing region?  

In central Ohio decisions are made daily to impact its regional ability to thrive while also balancing the needs of its environmental and social systems. Sandy Doyle-Ahern (president, EMH&T) will describe efforts within the region to invest in sustainable growth. 

In a lively and dynamic conversation with moderator Josh Knights (Sustainability Institute at Ohio State), Herrington and Doyle-Ahern will discuss how setting and achieving sustainable development goals through planning, engineering, and additional organizational strategies can improve environmental quality and limit the negative impacts of unrestrained economic growth.  

Join this program for a candid conversation on human society – local, regional, and global development, and the sustainable development strategies in practice designed to enhance well-being and steer us from danger. Learn what we can do in the 21st Century to both confront the challenging findings in the support of the limits to growth, and to think about humanity’s global sustainable development, and strategies to align towards a different, more ecologically balanced future in the central Ohio region and beyond.
