snow east of the mountains

air pollution and resulting acid rain severely affecting lakes and

damaging forests; metal smelting, coal-burning utilities, and

vehicle emissions impacting on agricultural and forest productivity;

ocean waters becoming contaminated due to agricultural, industrial,

mining, and forestry activities
