Which U.S. federal law was passed during the "Environmental Protection" era of 1960?

The Multiple-Use and Sustained-Yield Act was a significant piece of legislation that emerged during the "Environmental Protection" era of the 1960s. It was passed in 1960 and established the principle that national forests should be managed to provide a variety of resources and recreational opportunities for multiple uses, including timber harvesting, grazing, and recreation, while also ensuring sustainability. This law reflected the growing recognition of the need to balance economic interests with environmental stewardship, setting a framework for managing public lands in a way that benefits a wide range of stakeholders while conserving natural resources.

In contrast, the other options, while important, were enacted at different times or under different focuses. For example, the Fish and Wildlife Act was passed later and focused specifically on enhancing wildlife conservation efforts, while the Wilderness Act established a system to protect designated wilderness areas in 1964. The National Environmental Protection Act (NEPA), passed in 1969, was pivotal in creating a framework for environmental assessments but came about later than the Multiple-Use and Sustained-Yield Act. Understanding the timing and intent behind each of these laws provides clarity on why the Multiple-Use and Sustained-Yield Act is the correct answer in the context of the 1960s environmental
