How did the warmer climate affect the environment in which paleo-indians lived?

The warmer climate that came to be after the end of the Ice Age significantly improved the lives of the Paleo-Indians. Because the ice sheets were now gone, and the climate got warmer and with more precipitation, the once icy and snowy landscape turned into wast green forests and into vast prairie. This conditions allowed the Paleo-Indians to migrate throughout most of North America and not be restricted to certain parts of the continent, and also now they were able to get their hands into agriculture, and the food sources from the nature were much bigger and much more stable with all the fruits and vegetables growing around, and the amount of rivers significantly increased which enabled the people to have fish on their menus very often too.
