Who authored The Population Bomb in 1968, warning about unchecked population growth?

The correct answer is Paul Ehrlich, who authored "The Population Bomb" in 1968. In this influential book, Ehrlich argued that exponential population growth would lead to widespread famine and societal collapse unless measures were taken to control population size. He emphasized the environmental and resource challenges posed by a rapidly increasing population, which sparked significant discussion and debate about sustainability and environmental policy. Ehrlich's work remains relevant in contemporary discussions about population dynamics and resource management, highlighting the interconnectedness of population, environment, and social stability.

In contrast, Thomas Malthus, known for his earlier theories on population growth in the early 19th century, focused on the idea that population growth would outstrip food supply, but he did not directly author "The Population Bomb." Upton Sinclair was a social reformer and author known primarily for his works on social justice and labor conditions, such as "The Jungle," but he did not focus on population issues in the same way. Lemuel Shattuck, an early American public health advocate, contributed to public health standards and education but did not write about population growth in the context that Ehrlich did.
