Garrett Hardin was an American ecologist and philosopher, best known for his work on environmental issues and population control. He gained prominence for his 1968 essay, "The Tragedy of the Commons," which discusses how individuals acting in their self-interest can deplete shared resources, leading to negative consequences for society. Hardin's ideas have influenced discussions on sustainability and resource management. He advocated for policies that limit population growth and promote responsible use of resources, emphasizing the need for collective action to address environmental challenges. His work remains relevant in debates about climate change and sustainable development.
