ANSWER: False
Answer to Question 2
ANSWER: In the late 20th century, many trees in Germany showed signs of a blight that was due, in part, to acid deposition. Apparently, acidic particles raining down on the forest floor for decades caused a chemical imbalance in the soil that, in turn, causes serious deficiencies in certain elements necessary for the trees growth. The trees were thus weakened and become susceptible to insects and drought. The impact on large forests was called Waldsterben, or forest death. The same type of processes may have affected North American forests, but at a much slower pace, with symptoms apparent in many forests at higher elevations from southeastern Canada to South Carolina.
