During Roosevelt's presidency, many African American migrated from the South to the urban North. In the North, they were able to vote and had more job opportunities. The South was a worse place for black Americans to live. Roosevelt spoke against lynching and met with African American civil rights leaders.

This tension led to violence, like the race riot in 1943 Detroit.
I would say that a significant change affecting the natural environment and biodiversity could be the cultivation of corn and beans in mesoamerica which probably required the clearing of some land for the purpose. In populous societies such as the Aztecs the amount of cultivation would have been significant to feed a large population.
