What is the projected result of converting 25% or less of crop and rangelands in the United States to forests with native trees? (Site 1)

one of the projected result in converting 25% or less of crop and rangelands with native trees in the united states is that around 30% percent of food supply will be reduced.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
