Question: What is the main idea of this paragraph Paul Ehrlich, known for his advocacy of zero population growth to address environmental concerns, might find elements of support for the one-child policy in China. Ehrlich has expressed concerns about the environmental impact of a rapidly growing population and the strain it puts on the planet's resources. From his perspective, the policy's initial goal of slowing population growth could align with his broader ideas. However, Ehrlich has also stressed the importance of achieving population control through voluntary measures and education rather than coercion. Therefore, he might be critical of the forceful implementation and human rights abuses associated with the policy. Ehrlich's stance would likely emphasize the need for ethical and voluntary approaches to achieve population stability.
