Why did Big Ma allow Mr. Anderson to cut down the Logan's trees?

Big Ma allowed Mr. Anderson to cut down the Logan family's trees because she believed it was the only way to protect her family's land and livelihood. Facing pressure from the Andersons, who were wealthier and wielded more power in the community, she felt compelled to compromise to avoid further conflict or potential loss of the land. Big Ma's decision reflects her pragmatic approach to survival in a racially and economically oppressive environment.
