Answer:
d. rotate different crops that are grown each season
Step-by-step explanation:
because different crops need different recources and that gives it a break its the only reasonable answer
allow livestock to overgraze the pasture makes zero sense and would make the problem much worse
remove trees and other natural vegetation would also hurt the environment
overwater the ground causing soil erosion its better but would do nothing to aid in the goal
so hense the last one(my family are farmers)
