On November 15, 2022, it is estimated that for the first time Earth’s population exceeded 8 billion humans. But what is Earth’s sustainable carrying capacity of humans? Dr. Christopher Tucker is the Chairman of the American Geographic Society and author of the book “A Planet of 3 Billion.” He believes that we have far exceeded a sustainable number of humans on the planet and says that we are headed toward a catastrophic outcome if we don’t start significantly reducing the overall population of the planet by the end of the century.
In this interview, Dr. Tucker shares why the education and empowerment of young women and girls is the key to reducing global population to a more manageable carrying capacity. He talks about how we can avoid catastrophe by “shrinking to abundance,” how leaders should be thinking about global population and a future that may not be incented by growth, and he gives his very candid, critical assessment of people and countries that say we need to continue growing Earth’s population. He finishes the interview by talking about the mistakes we are making today that the people of 2073 will look back at in disbelief.
Dr. Christopher Tucker has spent the last two decades at the intersection of technology, strategy, geography and national security as an innovator, investor, social entrepreneur, author, and strategic advisor to the US national security community. As Chairman of the American Geographical Society, he launched a multi-year strategic dialog known as Geography2050, focused on the vital trends that will reshape the geography of our planet over the coming decades. He has served on a wide variety of public sector, corporate, and non-profit boards. He holds a BA, MA, and PhD from Columbia University. His passion for geography and the fate of future generations animates this work.
