Acorp and Beeco are companies that each manufacture pesticide X. Their plants are located along the same river. During a specific 24-hour period, each plant discharged pesticide into the river. Both plants were operated negligently and such negligence caused the discharge of the pesticide into the river. Landesmann operated a cattle ranch downstream from the plants of Acorp and Beeco. Landesmann's cattle drank from the river and were poisoned by the pesticide. The amount of the discharge from either plant alone would not have been sufficient to cause any harm to Landesmann's cattle. If Landesmann asserts a claim against Acorp and Beeco, what, if anything, will Landesmann recover?
