Final answer:
The CCC promoted conservation through reforesting projects and improvements to parks, while the TVA focused on flood control, hydroelectric power, and educational programs.
Step-by-step explanation:
The Civilian Conservation Corps (CCC) and the Tennessee Valley Authority (TVA) both promoted conservation in different ways. The CCC employed millions of young men in reforesting projects and improvements to national and state parks. They planted billions of trees and established numerous parks, leaving a lasting legacy of environmental conservation. On the other hand, the TVA focused on developing an entire region by controlling river flow to prevent flooding and providing electricity to factories and rural homes, which encouraged industrial growth while also implementing educational programs on crop rotation, soil replenishment, and reforestation. Both the CCC and TVA played important roles in conservation efforts during the 1930s.
