Paula

A factor to consider is that God had only said “when you eat you die”. He never said anything about additional penalties like cursing the earth. Both Adam and Eve became mortal when they ate, but God added to Adam’s penalty by cursing the ground. So the curse on the ground must be tied to Adam’s unique rebellion.

Or from another angle: God expressly stated that “Because you listened (perhaps meaning he “only listened and did not act”?)… and ate, the ground is cursed”. Adam both ate and “listened”, the ground he was taken from was cursed because of him, and sin was attributed to him alone according to Paul (Rom. 5:12).
