Final answer:
The Civilian Conservation Corps (CCC) was established on March 31, 1933, and continued until 1942. It employed around 2 million young men and played a significant role in environmental conservation and the development of state and national parks.
Step-by-step explanation:
The Civilian Conservation Corps (CCC) was created on March 31, 1933, as part of President Franklin D. Roosevelt's New Deal to combat the Great Depression. The CCC aimed to provide jobs for young men and to engage in environmental conservation efforts. It operated from its inception until America's entry into World War II, ending in 1942. During its time, the CCC employed approximately 2 million young men between the ages of 18 to 25, and it established 711 state parks, contributed to forestry management and fighting soil erosion, and planted an estimated 3 billion trees. The majority of the wages earned by CCC workers were sent to support their families, demonstrating a commitment not only to conservation but also to providing financial relief to American families during a time of economic hardship.
