Paul Ehrlich Discusses Overpopulation Solutions and Sustainability Challenges

Paul Ehrlich, Stanford Professor Emeritus, discusses overpopulation, citing Sir Partha Dasgupta's study suggesting a sustainable population of 3.2 billion. Despite China's declining population, he argues overpopulation strains resources and harms the environment. 

Ehrlich emphasizes equitable food distribution, empowering women for smaller families, and systemic changes like carbon taxes. He highlights the need for social science solutions and global cooperation, urging young people to educate themselves and act on sustainability issues.
