Destroy all lands opponents control, Destroy all lands that enter the battlefield under an opponent's control, Lock, Mass Land Denial
Yavimaya causes all lands to be Forests in addition to their other types, thus Life and Limb causes all lands to be 1/1 Saproling creatures.
Because Ethereal Absolution gives all creatures your opponents control -1/-1, they die as a state-based action due to having zero toughness.
Whenever an opponent plays a land, it will also die as a state-based action.
